Green Power: Calculator

Compiling data on environmental impacts of electricity consumption is an important first step in an institutional green power program. The following three tools can help:

1) The EPA E-Grid database contains information on every U.S. utility's resource mix and emissions.

2) The EPA Power Profiler Tool allows users to calculate emissions from electric utility companies on a pounds per MWh basis.

3) The GHG Protocol Corporate Standard provides detailed guidance on cost-effective tracking of greenhouse gas emissions.

4) The EPA GHG Calculator Tool quantifies the causal link between pollution prevention and the corresponding decrease in greenhouse gases.

5) The EPA Pollution Prevention Cost Calculator helps calculate the financial dollar savings from implementing pollution prevention activities.
