estimate of your personal greenhouse gas emissions or your family’s greenhouse gas emissions. Then move on to the next section of the calculator to explore actions you and/or your family can take to lower your emissions while reducing your energy and waste disposal costs. For each action you choose to take, the calculator displays the amount of emissions you could avoid and how that amount relates to your total emissions.

ACUP Climate Commitment
•ACUP Member Commitments:
•Initiate program to “achieve climate neutrality as soon as possible” •Within two months of signature, create institutional structures to guide development and implementation of plan; •Within one year of signature, complete comprehensive inventory of all greenhouse gas emissions •Within two years, set target date for achieving carbon neutrality, actions to make this goal part of the curriculum, mechanisms to track progress.
Violent Weather Events
Global number and percentage of intense hurricanes is increasing
Projections of Future Climate Change
Best estimate for low scenario (B1) is 1.8°C (likely range is 1.1°C to 2.9°C), and for high scenario (A1FI) is 4.0°C (likely range is 2.4°C to 6.4°C).
GHG Trends
CO2, CH4 and N2O Concentrations - far exceed pre-industrial values - increased markedly since 1750 due to human activities
Relatively little variation before the industrial era
