The large number of definitions of sustainability proposed in the 1980's have been refined into a smaller number of positions on the relevant questions in the 1990's. The most prominent of these are based on the idea of maintaining a capital stock. I call this the capital theory approach (CTA). Though these concepts are beginning to inform policies there are a number of difficulties in applying this approach in a theoretically valid manner and a number of critics of the use of the CTA as a guide to policy. First, I examine the internal difficulties with the CTA and continue to review criticisms from outside the neoclassical normative framework. The accounting approach obscures the underlying assumptions used and gives undue authoritativeness to the results. No account is taken of the uncertainty involved in sustainability analysis of any sort. In addition, by focusing on a representative consumer and using market (or contingent market) valuations of environmental resources, the approach (in common with most normative neoclassical economics) does not take into account distributional issues or accommodate alternative views on environmental values. Finally, I examine alternative approaches to sustainability analysis and policy making. These approaches accept the open-ended and multi-dimensional nature of sustainability and explicitly open up to political debate the questions that are at risk of being hidden inside the black-box of seemingly objective accounting.I.INTRODUCTIONThe Brundtland Report (WCED, 1987) proposed that sustainable development is "development that meets the needs of the present generation while letting future generations meet their own needs". Economists initially had some difficulty with this concept, some dismissing it1 and others proliferating a vast number of alternative definitions and policy prescriptions (see surveys by: Pezzey, 1989; Pearce et al., 1989; Rees, 1990; Lélé, 1991).In recent years, economists have made some progress in articulating their conception of sustainability. The large number of definitions of sustainability proposed in the 1980's have been refined into a smaller number of positions on the relevant questions in the 1990's. There is agreement that sustainability implies that certain indicators of welfare or development are non-declining over the very long term, that is development is sustained (Pezzey, 1989). Sustainable development is a process of change in an economy that does not violate such a sustainability criterion. Beyond this, the dominant views are based on the idea of maintaining a capital stock as a prerequisite for sustainable development. Within this school of thought there are opposing camps which disagree on the empirical question of the degree to which various capital stocks can be substituted for each other, though there has been little actual empirical research on this question.There is a consensus among a large number of economists that the CTA is a useful means of addressing sustainability issues.2 Capital theory concepts are beginning to inform policy, as in the case of the UN recommendations on environmental accounting and the US response to them (Beardsley, 1994; Carson et al., 1994; Steer and Lutz, 1993). There are, however, a growing number of critics who question whether this is a useful way to address sustainability (eg. Norgaard, 1991; Amir, 1992; Common and Perrings, 1992; Karshenas, 1994; Pezzey, 1994; Common and Norton, 1994; Faucheux et al., 1994; Common, 1995). The literature on sustainable development and sustainability is vast and continually expanding. There are also a large number ofsurveys of that literature (eg. Tisdell, 1988; Pearce et al., 1989; Rees, 1990; Simonis, 1990; Lélé, 1991; Costanza and Daly, 1992; Pezzey, 1992; Toman et al., 1994). I do not intend to survey this literature.The aim of this paper is to present a critique of the capital theory approach to sustainability (CTA henceforth) as a basis for policy. This critique both outlines the difficulties in using and applying the CTA from a viewpoint internal to neoclassical economics and problems with this approach from a viewpoint external to neoclassical economics. I also suggest some alternative approaches to sustainability relevant analysis and policy. The neoclasscial sustainability literature generally ignores the international dimensions of the sustainability problem. I also ignore this dimension in this paper.The paper is structured as follows. In the second section, I discuss the background to the emergence of the capital theory approach, while the third section briefly outlines the basic features of the approach. The fourth section examines the limitations of the CTA from within the viewpoint of neoclassical economics and the debate between proponents of "weak sustainability" and "strong sustainability". The following sections examine the drawbacks of this paradigm from a viewpoint external to neoclassical economics and discuss alternative methods of analysis and decision-making for sustainability. The concluding section summarizes the principal points.SHIFTING DEBATE: EMERGENCE OF THE CAPITAL THEORY II. THEAPPROACHMuch of the literature on sustainable development published in the 1980's was vague (see Lélé, 1991; Rees, 1990; Simonis, 1990). There was a general lack of precision and agreement in defining sustainability, and outlining appropriate sustainability policies. This confusion stemmed in part from an imprecise demarcation between ends and means. By "ends" I mean the definition ofsustainability ie. what is to be sustained, while "means" are the methods to achieve sustainability or necessary and/or sufficient conditions that must be met in order to do the same. As the goal of policy must be a subjective choice, considerable debate surrounded and continues to surround the definition of sustainability (eg. Tisdell, 1988). As there is considerable scientific uncertainty regarding sustainability possibilities, considerable debate continues to surround policies to achieve any given goal.Sharachchandra Lélé (1991) stated that "sustainable development is in real danger of becoming a cliché like appropriate technology - a fashionable phrase that everyone pays homage to but nobody cares to define" (607). Lélé pointed out that different authors and speakers meant very different things by sustainability, and that even UNEP's and WCED's definitions of sustainable development were vague, and confused ends with means. Neither provided any scientific examination of whether their proposed policies would lead to increased sustainability. "Where the sustainable development movement has faltered is in its inability to develop a set of concepts, criteria and policies that are coherent or consistent - both externally (with physical and social reality) and internally (with each other)." (613). Judith Rees (1990) expressed extreme skepticism concerning both sustainable development and its proponents. “It is easy to see why the notion of sustainable development has become so popular ... No longer does environmental protection mean sacrifice and confrontation with dominant materialist values” (435). She also argued that sustainable development was just so much political rhetoric. A UNEP report stated: "The ratio of words to action is weighted too heavily towards the former" (quoted in Simonis, 1990, 35). In the early days of the sustainability debate, vagueness about the meaning of sustainability was advantageous in attracting the largest constituency possible, but in the longer run, greater clarity is essential for sustaining concern.In the 1990's many people have put forward much more precisely articulated definitions of sustainable development, conditions and policies required to achieve sustainability, and criteria toassess whether development is sustainable. This has coincided with a shift from a largely politically-driven dialogue to a more theory-driven dialogue. With this has come a clearer understanding of what kinds of policies would be required to move towards alternative sustainability goals, and what the limits of our knowledge are. There is a stronger awareness of the distinction between ends and means. Most, but not all (eg. Amir, 1992), analysts agree that sustainable development is a meaningful concept but that the claims of the Brundtland Report (WCED, 1987) that growth just had to change direction were far too simplistic.There is a general consensus, especially among economists, on the principal definition of sustainable development used by David Pearce et al. (1989, 1991): Non-declining average human welfare over time (Mäler, 1991; Pezzey, 1992; Toman et al., 1994).3 This definition of sustainability implies a departure from the strict principle of maximizing net present value in traditional cost benefit analysis (Pezzey, 1989), but otherwise it does not imply a large departure from conventional economics. John Pezzey (1989, 1994) suggests a rule of maximizing net present value subject to the sustainability constraint of non-declining mean welfare. It encompasses many but not all definitions of sustainability. For example, it excludes a definition of sustainability based on maintaining a set of ecosystem functions, which seems to be implied by the Holling-sustainability criterion (Common and Perrings, 1992; Holling, 1973, 1986) or on maintaining given stocks of natural assets irrespective of any contribution to human welfare. A sustainable ecosystem might not be an undesirable goal but it could be too strict a criterion for the goal of maintaining human welfare (Karshenas, 1994) and could in some circumstances lead to declining human welfare. Not all ecosystem functions and certainly not all natural assets may be necessary for human welfare. Some aspects of the natural world such as smallpox bacteria may be absolutely detrimental to people. In the context of the primary Pearce et al. definition, the Holling-sustainability criterion is a means not an end.The advantage of formalizing the concept of sustainability is that this renders it amenable to analysis by economic theory (eg. Barbier and Markandya, 1991; Victor, 1991; Common and Perrings, 1992; Pezzey, 1989, 1994; Asheim, 1994) and to quantitative investigations (eg. Repetto et al., 1989; Pearce and Atkinson, 1993; Proops and Atkinson, 1993; Stern, 1995). Given the above formal definition of sustainability, many economists have examined what the necessary or sufficient conditions for the achievement of sustainability might be. Out of this activity has come the CTA described in the next section. The great attractiveness of this new approach is that it suggests relatively simple rules to ensure sustainability and relatively simple indicators of sustainability. This situation has seemingly cleared away the vagueness that previously attended discussions of sustainability and prompted relatively fast action by governments and international organizations to embrace specific goals and programs aimed at achieving this notion of the necessary conditions for sustainability.III. THE ESSENCE OF THE CAPITAL THEORY APPROACHThe origins of the CTA are in the literature on economic growth and exhaustible resources that flourished in the 1970s, exemplified by the special issue of the Review of Economic Studies published in 1974 (Heal, 1974). Robert Solow (1986) built on this earlier literature and the work of John Hartwick (1977, 1978a, 1978b) to formalize the constant capital rule. In these early models there was a single non-renewable resource and a stock of manufactured capital goods. A production function produced a single output, which could be used for either consumption or investment using the two inputs. The elasticity of substitution between the two inputs was one which implied that natural resources were essential but that the average product of resources could rise without bound given sufficient manufactured capital.The models relate to the notion of sustainability as non-declining welfare through the assumption that welfare is a monotonically increasing function of consumption (eg. Mäler, 1991). The path ofconsumption over time (and therefore of the capital stock) in these model economies depends on the intertemporal optimization rule. Under the Rawlsian maxi-min condition consumption must be constant. No net saving is permissible as this is regarded as an unjust burden on the present generation. Under the Ramsey utilitarian approach with zero discounting consumption can increase without bound (Solow, 1974). Here the present generation may be forced to accept a subsistence standard of living if this can benefit the future generations however richer they might be. Paths that maximize net present value with positive discount rates typically peak and then decline so that they are not sustainable (Pezzey, 1994). Pezzey (1989) suggested a hybrid version which maximizes net present value subject to an intertemporal constraint that utility be non-declining. In this case utility will first increase until it reaches a maximum sustainable level. This has attracted consensus as the general optimizing criterion for sustainable development. Geir Asheim (1991) derives this condition more formally.Under the assumption that the elasticity of substitution is one, non-declining consumption depends on the maintenance of the aggregate capital stock ie. conventional capital plus natural resources, used to produce consumption (and investment) goods (Solow, 1986). Aggregate capital, W t,and the change in aggregate capital are defined by:W t=p Kt K t + p Rt S t (1)∆W t=p Kt∆K t + p Rt R t (2)where S is the stock of non-renewable resources and R the use per period. K is the manufactured capital stock and the p i are the relevant prices. In the absence of depreciation of manufactured capital, maintenance of the capital stock implies investment of the rents from the depletion of the natural resource in manufactured capital - the Hartwick rule (Hartwick 1977, 1978a, 1978b). Income is defined using the Hicksian notion (Hicks, 1946) that income is the maximum consumption in a period consistent with the maintenance of wealth. Sustainable income is,therefore, the maximum consumption in a period consistent with the maintenance of aggregate capital intact (Weitzman, 1976; Mäler, 1991) and for a flow of income to be sustainable, the stock of capital needs to be constant or increasing over time (Solow, 1986).The initial work can be extended in various ways. The definition of capital that satisfies these conditions can be extended to include a number of categories of "capital": natural, manufactured, human, and institutional.4 Natural capital is a term used by many authors (it seems Smith (1977) was the first) for the aggregate of natural resource stocks that produce inputs of services or commodities for the economy. Some of the components of natural capital may be renewable resources. Manufactured capital refers to the standard neoclassical definition of "a factor of production produced by the economic system" (Pearce, 1992). Human capital also follows the standard definition. Institutional capital includes the institutions and knowledge necessary for the organization and reproduction of the economic system. It includes the ethical or moral capital referred to by Fred Hirsch (1976) and the cultural capital referred to by Fikret Berkes and Carl Folke (1992). For convenience I give the name 'artificial capital' to the latter three categories jointly. None of these concepts is unproblematic and natural capital is perhaps the most problematic. Technical change and population growth can also be accommodated (see Solow, 1986).Empirical implementation of the CTA tends to focus on measurement of sustainable income (eg. El Serafy, 1989; Repetto, 1989) or net capital accumulation (eg. Pearce and Atkinson, 1993; Proops and Atkinson, 1993) rather than on direct estimation of the capital stock.5 The theoretical models that underpin the CTA typically assume a Cobb-Douglas production function with constant returns to scale, no population growth, and no technological change. Any indices of net capital accumulation which attempt to make even a first approximation to reality must take these variables into account. None of the recent empirical studies does so. For example, David Pearce and Giles Atkinson (1993) present data from eighteen countries on savings and depreciation of natural andmanufactured capital as a proportion of GNP. They demonstrate that only eight countries had non-declining stocks of total capital, measured at market prices, and thus passed a weak sustainability criterion of a constant aggregate capital stock, but their methodology ignores population growth, returns to scale or technological change.IV.INTERNAL APPRAISAL OF THE CAPITAL THEORY APPROACHIn this section, I take as given the basic assumptions and rationale of neoclassical economics and highlight some of the technical problems that are encountered in using the CTA as an operational guide to policy. From a neoclassical standpoint these might be seen as difficulties in the positive theory that may lead to difficulties in the normative theory of sustainability policy. In the following section, I take as given solutions to these technical difficulties and examine some of the problems inherent in the normative neoclassical approach to sustainability.a.Limits to Substitution in Production and "Strong Sustainability"Capital theorists are divided among proponents of weak sustainability and strong sustainability. This terminology is confusing as it suggests that the various writers have differing ideas of what sustainability is.6 In fact they agree on that issue, but differ on what is the minimum set of necessary conditions for achieving sustainability. The criterion that distinguishes the categories is the degree of substitutability believed to be possible between natural and artificial capital.7The weak sustainability viewpoint follows from the early literature and holds that the relevant capital stock is an aggregate stock of artificial and natural capital. Weak sustainability assumes that the elasticity of substitution between natural capital and artificial capital is one and therefore that there are no natural resources that contribute to human welfare that cannot be asymptotically replaced by other forms of capital. Reductions in natural capital may be offset by increases inartificial capital. It is sometimes implied that this might be not only a necessary condition but also a sufficient condition for achieving sustainability (eg. Solow, 1986, 1993).Proponents of the strong sustainability viewpoint such as Robert Costanza and Herman Daly (1992) argue that though this is a necessary condition for sustainability it cannot possibly be a sufficient condition. Instead, a minimum necessary condition is that separate stocks of aggregate natural capital and aggregate artificial capital must be maintained. Costanza and Daly (1992) state: "It is important for operational purposes to define sustainable development in terms of constant or nondeclining total natural capital, rather than in terms of nondeclining utility" (39).8 Other analysts such as members of the "London School" hold views between these two extremes (see Victor, 1991). They argue that though it is possible to substitute between natural and artificial capital there are certain stocks of "critical natural capital" for which no substitutes exist. A necessary condition for sustainability is that these individual stocks must be maintained in addition to the general aggregate capital stock.The weak sustainability condition violates the Second Law of Thermodynamics, as a minimum quantity of energy is required to transform matter into economically useful products (Hall et al., 1986) and energy cannot be produced inside the economic system.9 It also violates the First Law on the grounds of mass balance (Pezzey, 1994). Also ecological principles concerning the importance of diversity in system resilience (Common and Perrings, 1992) imply that minimum quantities of a large number of different capital stocks (eg. species) are required to maintain life support services. The London School view and strong sustainability accommodate these facts by assuming that there are lower bounds on the stocks of natural capital required to support the economy, in terms of the supply of materials and energy, and in terms of the assimilative capacity of the environment, and that certain categories of critical natural capital cannot be replaced by other forms of capital.Beyond this recognition it is an empirical question as to how far artificial capital can substitute for natural capital. There has been little work on this at scales relevant to sustainability. However, the econometric evidence from studies of manufacturing industry suggest on the whole that energy and capital are complements (Berndt and Wood, 1979).In some ways the concept of maintaining a constant stock of aggregate natural capital is even more bizarre than maintaining a non-declining stock of total capital. It seems more reasonable to suggest that artificial capital might replace some of the functions of natural capital than to suggest that in general various natural resources may be substitutes for each other. How can oil reserves substitute for clean air, or iron deposits for topsoil? Recognizing this, some of the strong sustainability proponents have dropped the idea of maintaining an aggregate natural capital stock as proposed by Costanza and Daly (1992) and instead argue that minimum stocks of all natural resources should be maintained (Faucheux and O'Connor, 1995). However, this can no longer really be considered an example of the CTA. Instead it is an approach that depends on the concept of safe minimum standards or the precautionary principle. The essence of the CTA is that some aggregation of resources using monetary valuations is proposed as an indicator for sustainability.The types of models which admit an index of aggregate capital, whether aggregate natural capital or aggregate total capital, is very limited. Construction of aggregate indices or subindices of inputs depend on the production function being weakly separable in those subgroups (Berndt and Christensen, 1973). For example it is only possible to construct an index of aggregate natural capital if the marginal rate of substitution between two forms of natural capital is independent of the quantities of labor or capital employed. This seems an unlikely proposition as the exploitation of many natural resources is impractical without large capital stocks. For example, in the production of caught fish, the marginal rate of substitution, and under perfect competition the price ratio, between stocks of fresh water fish and marine fish should be independent of the number of fishingboats available. This is clearly not the case. People are not likely to put a high value on the stock of deep sea fish when they do not have boats to catch them with.If substitution is limited, technological progress might reduce the quantity of natural resource inputs required per unit of output. However, there are arguments that indicate that technical progress itself is bounded (see Pezzey, 1994; Stern, 1994). One of these (Pezzey, 1994) is that, just as in the case of substitution, ultimately the laws of thermodynamics limit the minimization of resource inputs per unit output. Stern (1994) argues that unknown useful knowledge is itself a nonrenewable resource. Technological progress is the extraction of this knowledge from the environment and the investment of resources in this activity will eventually be subject to diminishing returns.Limits to substitution in production might be thought of in a much broader way to include nonlinearities and threshold effects. This view is sometimes described as the "ecological" viewpoint on sustainability (Common and Perrings, 1992; Common, 1995) or as the importance of maintaining the "resilience" of ecological systems rather than any specific stocks or species. This approach derives largely from the work of Holling (1973, 1986). In this view ecosystems are locally stable in the presence of small shocks or perturbations but may be irreversibly altered by large shocks. Structural changes in ecosystems such as those that come about through human interference and particularly simplification, may make these systems more susceptible to losing resilience and being permanently degraded. There is clearly some substitutability between species or inorganic elements in the role of maintaining ecosystem productivity, however, beyond a certain point this substitutability may suddenly fail to hold true. This approach also asks us to look at development paths as much less linear and predictable than is implied in the CTA literature.All things considered, what emerges is a quite different approach to sustainability policy. It is probable that substitution between natural and artificial capital is limited, as is ultimately technicalchange. Additionally the joint economy-ecosystem system may be subject to nonlinear dynamics. This implies that eventually the economy must approach a steady state where the volume of physical economic activity is dependent on the maximum economic and sustainable yield of renewable resources or face decline ie. profit (or utility) maximizing use of renewable resources subject to the sustainability constraint. As in Herman Daly's vision (Daly, 1977) qualitative change in the nature of economic output is still possible. Sustainability policy would require not just maintaining some stocks of renewable resources but also working to reduce "threats to sustainability" (Common, 1995) that might cause the system to pass over a threshold and reduce long-run productivity.The notion of Hicksian income originally applied to an individual price-taking firm (Faucheux and O'Connor, 1995). However, even here it is not apparent that the myopic policy of maintaining capital intact from year to year is the best or only way to ensure the sustainability of profits into the future. If a competing firm makes an innovation that renders the firm's capital stock obsolete, the latter's income may drop to zero. This is despite it previously following a policy of maintaining its capital intact. The firm's income measured up to this point is clearly seen to be unsustainable. In fact its policy has been shown to be irrelevant to long-run sustainability. In the real world firms will carry out activities that may not contribute to the year to year maintenance of capital and will reduce short-run profits such as research and development and attempts to gain market share.10 These activities make the firm more resilient against future shocks and hence enhance sustainability.b.Prices for AggregationSupposing that the necessary separability conditions are met so that aggregation of a capital stock is possible, analysts still have to obtain an appropriate set of prices so that the value of the capital stock is a sustainability relevant value. The CTA is more or less tautological if we use the "right" prices. However, these correct "sustainability prices" are unknown and unknowable. A number of。

Background
Environmental accounting is set up on the basis of environmental resources deterioration and criticism of traditional accounting. In traditional accounting,there is a price and can be reflected in the accounting statement only if it has property ownership.But like the air, the oceans and the ozonosphere,they are essential to human while they Don’t have ownership,and they can’t involve in the accounting contents. That means these things’using and damaging by enterprises are not charged to operating costs.This not only inflates profits, even more serious is this would be an incentive for the behavior of sacrificing environment for current interest. 环境会计是在环境资源恶化和批评传统会计的基础上产生的。 环境会计是在环境资源恶化和批评传统会计的基础上产生的。 传统会计中,只有存在财产所有权才有价格,才能在会计账表中得以反映, 传统会计中,只有存在财产所有权才有价格,才能在会计账表中得以反映, 而如空气、海洋、 而如空气、海洋、臭氧层等对人类至关重要但无所有权的事物却不能成为会计 核算的内容,企业对这些事物的使用和损害并不记入经营成本, 核算的内容,企业对这些事物的使用和损害并不记入经营成本,这不仅使利润 虚增,更为严重的是对以牺牲环境来取得目前利益的行为的一种鼓励。 虚增,更为严重的是对以牺牲环境来取得目前利益的行为的一种鼓励。

The project team is thankful for their timely cooperation.ABSTRACTInternational and national standards, and in some cases corporate policies require that planned and scheduled audits be performed to verify all aspects of environmental compliance and to determine effective implementation of the environmental management program. An example of this can be found in the definition of auditing as provided by U. S. Environmental Protection Agency (EPA) Policy Statement on Environmental Auditing. It defines environmental auditing as follows:"Environmental auditing is a systematic, documented, periodic and objective review by regulated entities of facility operations and practices related to meetingenvironmental requirements. Audits can be designed to accomplish any or all of the following: verify compliance with environmental requirements, evaluate the effectiveness of environmental management systems already in place, or assess risksfrom regulated and unregulated materials and practices.Auditing serves as a quality assurance check to help improve the effectiveness of basic environmental management by verifying that management practices are in place, functioning and adequate. ''Many specifications further emphasize that the audit be performed to written procedures or checklists (to provide later documentation) by personnel who do not have direct responsibility for performing the activities being audited. The results of such audits are generally required to be documented, reported to, and reviewed by, responsible management. Follow-up action will be taken where indicated. The responsible organization can then take follow-up action as needed.An effective auditing program is a useful tool for improving environmental compliance. If developed properly, the program will point out areas of weakness and areas ofpotential problems. An auditing program will also identify environmental compliance activities that meet or exceed expectations.At the Pacific Northwest Laboratory(PNL), Environmental Audits used to consist of nontechnical auditors auditing to findings published in General Accounting Office reports. Today's practice of deploying a composite team of technical specialists and nontechncial auditors to audit to specific environmental programmatic requirements provides, we believe, a significant improvement.国际和国家的标准, 而且在一些情形企业的政策需要那计划了的和预定的稽核是运行到查证所有的环境服从的方面和决定环境管理的有效落实计画。
有关环境的会计英文
有关环境的会计英文Environmental accounting refers to the incorporation of environmental costs and benefits into an organization's financial reporting and decision-making processes. It involves tracking and assessing the environmental impact of an organization's activities, as well as the costs associated with environmental compliance and conservation efforts.There are several types of environmental accounting, including:1. Environmental cost accounting: This involves identifying and accounting for the costs associated with environmental protection and compliance, such as pollution control measures, waste disposal, and environmental remediation.2. Environmental performance accounting: This focuses on measuring and tracking an organization's environmental performance, such as energy consumption, greenhouse gas emissions, water usage, and waste generation, and reporting this information both internally and externally.3. Natural capital accounting: This involves valuing and accounting for the economic contribution of natural resources, such as forests, ecosystems, and biodiversity, and their depletion or degradation due to an organization's activities.4. Environmental risk accounting: This identifies and assesses the financial risks associated with an organization's exposure to environmental risks, such as climate change, natural disasters, and regulatory changes.Environmental accounting provides a comprehensive picture of an organization's environmental impact and helps address sustainability challenges. It can inform strategic decision-making, resource allocation, and risk management, and also allows organizations to demonstrate their commitment to environmental stewardship to stakeholders, investors, and customers.。
Environmental management accounting
Accounting for Environmental Costs
• F5 is concerned with information for internal decision making only. It is not concerned with how environmental information is reported externally • Four management accounting techniques (a) Input/output flow analysis (b) Flow cost accounting (c) Activity-based costing (d) Life-cycle costing
Activity-based costing
• Environmental costs would be grouped together into environmental cost pool & each pool would be associate with an environmental cost driver • As for ABC in general, this will lead to: (a) Increased awareness of how environmental costs behave (b) Better product pricing (c) Better production decisions
Managing environmental costs
• Environmental costs are becoming huge for some companies. Once identified, environmental costs can be controlled & reduced • There is increasing worldwide regulation & a need for regulatory reporting of environmental costs • Ethical issues-businesses should be aware of how their production methods will affect the environment • Improved brad image- ‘green’ ways of doing business can be a selling point • Associating environmental costs with individual products will lead to more accurate pricing & improved profitability

Conclusion ............................... (30)31 (32)Efficient Accounting SystemsThe existence and development of everything are under certain environmental conditions. Accounting, as one of the most important practice of human activities is not a cases outside. Accounting environment have the base sense for the smooth conduct of the activities of accounting, while various accounting environmental factors will have isolated impact on total activity of the accounting system. The study of the structure of the accounting environment system and the relations between the various elements in this system made us to be much more realistic in this area of accounting theoiy and practice, to build a harmonious Environmental System for clear direction, so as to promote the accounting cause of sustainable development.Chapter 1 Accounting1.1The decision of accountingAccounting is one of the fastest growing fields in the modern business world・Every new shore, school, restaurant, or filling station indeed, any new enterprise of any kind increases the demand for accountants・ Consequently, the demand for accountants is generally much greater than the supply. Government official often have a legal background: similarly, the men and women in management often have a background in accounting. They are usually familiar with the methodology of finance and fundamentals of fiscal and business administration・Today's accountants are as diverse as their job assignments・ Accountants may be male or female, outgoing or conservative, but they are all analytical. They mayhave backgrounds in art history or computer programming. They come from every ethnic and cultural background・The accounting backgrounds can open doors to most lines of business・ In short, accounting deals with all facets of an organization —purchasing, manufacturing, marketing, and distribution. This is why accounting provides such an excellent basis for business experience・ Accounting is an information system necessitated by the great complexity of modern business・1.2The functions of accountingOne of the most important functions of accounting is to accumulate and report financial information that shows ail organization^ financial position and the results of its operations to its interested users・ These users include managers, stockholders, banks and other creditors, governmental agencies, investment advisors, and the general public. For example, stockliolders must have an organization^ financial iiifonnation in order to measure its managementperfbnnance and to evaluate tlieii' own holdings・ Banks and other creditors must consider the financial strength of a business before permitting it to borrow funds. Potential investors need financial data in order to compare prospective investments. Also many laws require that extensive financial information be reported to the various levels of government. Businesses usually publish such reports at least annually. To meet the needs of the external users, a framework of accounting standards, principles and procedures known as ^generally accepted accounting principles^ have been developed to insure the relevance and reliability of the accounting information contained in these external financial reports. The subdivision of the accounting process that produces these external reports is referred to as financial accounting・Another important function of accounting is to provide the management inside an organization with the accounting iiifonnation needed in the organization^ internal decision-making, which relates to planning, control, and evaluation within an organization. For example, budgets are prepared under the directions of a company's controller on an annual basis and express the desires and goals of the company's management. A performance report is supplied to help a manager focus his attention on problems or opportunities that mightotherwise go unnoticed. Furthermore, cost-benefit data will be needed by a company^ management in deciding among the alternatives of reducing prices, increasing advertising, or doing both in attempt to maintain its market shares. The process of generating and analyzing such accounting information for internal decision -making is often referred to as managerial accounting and the related information reports being prepared are called internal management reports・ As contrasted with financial accounting, a management accounting information system provides both historical and estimated information that is relevant to the specific plans on more frequent basis・ And managerial accounting is not governed by generally accepted accounting principles.Chapter 2 Accounting environmentThe growth of organizations, changes in technology, government regulation, and the globalization of economy during the twentieth century have spurred the development of accounting・ As a result, a number of specialized fields of accounting have evolved in addition to financial accounting and managerial accounting, which include auditing, cost accounting, tax accounting, budgetary accounting, governmental and not -for-profit accounting, human resources accounting, environmental accounting, social accounting, international accounting, etc. For example, tax accounting encompasses the preparation of tax returns and the consideration of the tax consequences of proposed business transactions or alternative courses of action. Governmental and not-for-profit accounting specializes in recording and reporting the transactions of various governmental units and other not-for-profit organizations. International accounting is concerned with the special problems associated with the international trade of multinational business organizations. All forms of accounting, in the end, provide information to the related users and help them make decisions.Accountant the environment has, the development closely with accountant related, and decided that accountant the thought that the accounting theory, accountant organize, accountant the legal system as well as the accountancy level of development historic condition and the particular case・Studies accountant the environment the influence which develops to accountant,should take accountant the goat accountant suppose, the accounting standards as the clue.2.1 The goal of accountant is the starting point in which accounting environment affects the accounting information systemEach kind of accountant under the pattern accountant the goal concrete difference may sum up as accountant the environment different result. Looking from longitudinal, the different historical period, accountant the environment is different, accountant the goal is also different, from this causes the accounting information existence huge difference; Looking from crosswise, different national accountant the environment is different, accountant the goal content has the difference, its accounting iiifonnation is also unique. About accountant the goal, the theorists have “the policy-making usefill view” and "the management responsibility view" the stmggle・ What policy-making useful view interdependence is the developed capital market, the resources request and is entiusted with something the relations are establishes through the capital market. Thus, the resources entrusting party and is entrusted with something the side responsibility relations intermediary becomes because of the capital market fuzzy. But the responsibility view to base the resources request which forms in the direct intercourse with is entrusted with something the relations. Western various countries and the international accounting standards committee approve the policy-making useful view. If the international accounting standards committee said that “must focus the attention to provide to the economic decision-making useful iiifbnnation n. Comparatively speaking, the management responsibility view depends on each other accountant the environment and the Chinese present stage economic reform and the development actual situation even more tallies. The current our country financial inventory accountings essential target, should locate, in approaches the tmstee to report the fiduciary duty in the fulfillment situation. Because of from the time, the management responsibility view mainly faces the future, but faces in the past and the present. But in accountant confirmed that the standard and the measurement foundation s choices aspect, the foothold in the past and the present must be easier than in the future the foothold, provided the information quality even more drew close to the goal the request.Because just accountant the goal affects the accounting information systems basic reason, therefore, the environment embarks from accountant to accountant the goal locates,can cause the accounting theory to move toward the accounting practice from Yu the accounting practice.2.2accountants supposed has promulgated accountant between the external environment close relations which depended on each other with it.Accountant supposes is the accounting personnel the reasonable judgment which locates to the accounting the change which does not decide accountant who the environment makes, is the accounting basic premise Accountant supposes to financial inventory accounting has the overall importance influence, it is the behavior main body and the general situation embarks from accountant constructs the system info, American Accounting standards Committee Respective Accountant Research depaitment's first memoir is "accountant's fimdamental assumption^. Although theoretically speaking, the sound value information will have the guidance compared to the historical costs information regarding the user future economic decision-making, just like but US Chartered accountant the Association financial report Technical committee will publish the topic will be'Improvement Enterprise Reported that -- Customer Guidance" said that the numerous users did not advocate by the sound value pattern substitution historical costs pattern, its reason will mainly be stems from the guarantee financial report information consistency, reliable and the cost - benefit principle consideration. However, they advocate many kinds of measurement attribute mix valuation.Accountant supposes is based on the external environment uncertainty proposed that therefore, may say that accountant supposes is the accounting theory and accountant the environment connected border meeting point, depends on each other accountant with it the environment to have the extremely close relationship・2.3The accounting standards disclose accountant the environment to the accounting information requestAccountant the environment to accounting standards* influence, may manifest in the accounting standards technical nature, the social two aspects・1.Technical nature. The accountins standards were considered that is one kind of pure objective restraint organization, one merely technicals standard method, its goal is enables accounting practice processing the science, to be reasonable, to be consistent. Sinceproduces the behavior has universal restraint accountant after accountant the standard system, accountant reforms mainly displays in accountant the standard system s reform, but accountant standard system's reform, displays for concrete accountant the computing technique innovation.2・ Sociality. The different accounting standards will have the different accounting information, thus affects the different main body benefit, it will cause part of people to profit, but another part of people possibly suffer injury. The accounting standards produce the economic consequences prove its and impure objective. Accounting standards* sociality materially is the economic interest question, immediate influence to economic interest between related various aspects assignment. One of market economy's base elements is the fair competition ; All market economy participants cannot different form the rank difference because of the right status. If the administrative right trades the behavior with the market economy to unify in together, will destroy the market mechanism, will be unable to realize the market economy effective disposition resources function. Therefore accounting standards* formulation organization must be the neutral organization, guarantees the accounting standards fairness and the rationality.Chapter 3 Accounting SystemAccounting system refers to establish accounting and accounting supervision procedure and method of business activities. Effective accounting system should do:1.Confirmed and record all real business, timely and detailed description of economic business, so in the financial and accounting reports of economic business appropriately classified・2.Measurement value of economic business, so in the financial and accounting reports records in the appropriate monetary value・3.Determine the time, business to business records in the appropriate accounting period ・4.In the financial and accounting reports, business and proper disclosure of expression related matters・有效会计体系任何事物都是在一定的环境条件下存在和发展的,作为人类重要实践活动之一的会计活动也不例外。

elEditorialEnvironmental accounting:Emergy,systems ecology,and ecological modelling1.Environmental accounting:the need for an integrated perspectiveThe environmental performance and sustainability of human-dominated systems supported by both natural and human-driven flows can be explored by analysing different aspects:the envi-ronmental sustainability,the economic profitability,and the social desirability,all relevant to achieve a comprehensive understanding of the system under investigation.Energy analysis can provide a valuable perspective on the demand for commercial energy as well as the energy returned on energy invested (Cleveland et al.,1984;Herendeen,2004).The Emergy Synthesis method entails a donor-side viewpoint and expands the system boundary to the whole biosphere by account-ing for the global environmental support to systems and processes (Odum,1988,1996).Emergy accounting therefore considers free renewable inputs,matter and energy flows as well as direct and indirect labour flows not in terms of the benefits that humans can extract from them but rather in terms of the work performed by the biosphere to make them available (Brown and Ulgiati,2004).Other environmental accounting methods adopt a cost of pro-duction point of view and show so-called environmental footprints,i.e.the amounts of land,matter,and water required by a given pro-cess or the amount of carbon and other greenhouse gases released per unit product (Buonocore et al.,2012;Franzese et al.,2013;Hoekstra,2009;Häyhäet al.,2011;Steen-Olsen et al.,2012).Life Cycle Assessment (LCA)has an important role in assess-ing the environmental impacts of producing goods and services,avoiding the shortcomings related to the narrow perspective of short-term benefits and impacts.LCA can be extended to also include the indirect contribution of economic inputs,which typ-ically fall outside the boundary of conventional analyses,by means of hybrid approaches based on input–output analysis (Finnveden et al.,2009;Strømman et al.,2006,2009).Finally,other tools like geographical information systems (GIS)are useful to map and allo-cate resource supply,use,and impacts on reference territories (Sacchelli et al.,2013).All these perspectives,theories and methods should not be con-sidered as alternative to each other but instead complementary and all necessary to fully investigate processes and systems across multiple scales of analysis.This is particularly important when dealing with systems supported by natural resources and integrat-ing human-managed ecosystems and technologies playing a crucial role for human well-being.2.Integrating environmental accounting with ecological and climate change modellingEnvironmental accounting can be usefully integrated with eco-logical and climate change modelling to provide solid scientific information in support of policy makers committed to develop plans and targets for the sustainable management of natural resources and,ultimately,for the sustainable development of human societies.When environmental accounting is employed within the framework of environmental impact assessment and cli-mate change modelling,the analysis should embrace the changes that human-induced ecosystem perturbations cause to biogeo-physical factors and global biogeochemical cycles (Hallgren et al.,2013;Bonan,2008).These changes can be quantified through empirical measurements (either in situ or from satellite observa-tions)or by means of a modelling approach (Lee et al.,2011;Bright et al.,2013).Successful examples in this direction are given by the formulation of site-specific characterization factors (e.g.,the global warming potential,GWP)for biogenic CO 2emissions from biomass combustion,where both temporary changes in atmospheric CO 2concentration and albedo effects are taken into account (Cherubini et al.,2012;Guest et al.,2013).Ultimately,analysts working with different methods of environmental accounting and impact assess-ment have the opportunity to perform a joint effort to promote the adoption of metrics that better support the setting of global policy targets,as it is for instance the case of temperature-based metrics in relation to the commitment to limit global warming (Cherubini et al.,2013;Smith et al.,2012).Some of the articles presented in this issue show how emergy accounting can be usefully employed to investigate systems at different spatial and temporal scales,from specific production sys-tems,to cities,to large scale systems and global biogeochemical cycles,thus supporting the assessment of temporal changes and future targets vital in the framework of climate change research and policy.3.Goal of this special issueThe main goal of this special issue is to present a set of articles showing the state of the art and some theoretical and procedural advancement in emergy theory and accounting,emphasizing the potential for integration between the emergy synthesis method and other methodological approaches for environmental accounting,environmental impact assessment,and ecological modelling.0304-3800/$–see front matter © 2013 Published by Elsevier B.V./10.1016/j.ecolmodel.2013.10.0072Editorial/Ecological Modelling271 (2014) 1–34.Papers presented in the special issueThe papers gathered in this special issue were presented at the 7th Biennial Emergy Research Conference,a biennial conference providing a venue and forum for meaningful discussion expressly dedicated to theory,principles,and applications of the emergy methodology.The papers explore different aspects of emergy theory and methodology,among which:a)the possible integration of emergy and other environmental accounting methods;b)the integrated use of emergy accounting and ecological modelling,with particu-lar reference to urban metabolism,climate and land use change, and ecosystem services assessment;c)the use of conventional and innovative modelling techniques for spatial analysis,emergy inputs and conversion factors calculation,and uncertainty assess-ment.Raugei et al.(2013)explore obstacles and potential added value of integrating emergy into LCA,highlighting how emergy could be used as a valuable complement,rather than an alternative,to existing life cycle impact assessment metrics.Buonocore et al.(2013)propose a multi-method approach to environmental accounting by performing an assessment encom-passing material,energy,and emergy demand as well as relevant emissions to explore the environmental performance and sustain-ability of forestry operations.Lee(2013),starting from the observation that pulsing is preva-lent in nature,investigates the relation between frequency and pulsing of resourceflows and power output maximization in a system.Campbell et al.(2013)calculate specific emergies of the global flows of six biologically active elements and two compounds for use in waste management and environmental accounting in order to establish emergy reference values to guide environmental man-agement policies.Further,they compare the specific emergies of globalflows of elements during the Industrial Age to those in the Preindustrial Era to determine the extent of changes and the sen-sitivity of the global biogeochemical system to the5-fold increase in the emergy use of the global system over the past160years.Hudson and Tilley(2013)propose the use of Monte Carlo simu-lations to assess the uncertainty in emergy evaluations.Their study highlights the need for the community of emergy analysts to reg-ularly perform an assessment of the uncertainty affecting their results.Giannantoni(2013)presents a real novelty in mathematical modelling represented by the so-called“emerging solutions”.This innovative mathematical modelling approach is discussed through the case of smart grids,with particular reference to their large scale “intrinsic”instability and their recognized strong vulnerability to cyber-attacks.Patterson(2013)describes and characterizes a new matrix alge-bra method named“the reflexive method”capable of calculating transformities from ecological and economic network data.Reiss et al.(2013)apply the landscape development intensity (LDI)index to facilitate calculation of wetland mitigation poten-tial and credit awards for mitigation banks,also highlighting that, regardless of the used tool,consideration of potential wetland func-tional lift should incorporate a landscape perspective.Liu et al.(2013)describe a forecasting model,named“emergy-based urban dynamic model”,capable of accurately simulating the observed resource consumption,economic growth,and environ-mental impact of Beijing from1999to2039.Mellino et al.(2013)use emergy accounting integrated in a GIS framework to quantify and map the regional distribution of envi-ronmentalflows(solar radiation,rainfall,wind,and geothermal heat),thus offering an emergy perspective of the spatial distribu-tion of naturalflows within a regional boundary.Watanabe and Ortega(2013),considering the importance of climate change,freshwater scarcity,soil erosion and other envi-ronmental issues,present a model that simulates the impact of land-use change on the ecosystem services related to water and carbon biogeochemical processes in the Taquarizinho river basin (Brazil).Ghisellini et al.(2013)assess the environmental performance of the Italian agricultural system over a time series of25years coupling emergy accounting method and decomposition analy-sis technique,thus identifying the major drivers of performance changes to be used as the basis for future policy scenarios.Morandi et al.(2013)propose an innovative approach to the evaluation of the main emergyflows entering a system using set theory.5.Concluding remarksThe Guest Editors hope that this volume will boost a construc-tive and collaborative interaction among the analysts committed to integration and synergic use of different methods of environmental accounting.AcknowledgementsA special thank is due to all the reviewers who contributed their time and valuable effort.Without their work and scientific support this special
