Methods of Estimating Emission Reductions from Energy Efficiency and Renewables

U.S. Environmental Protection Agency
Completed July 2005

Synapse analyzed different methods to estimate emission reductions from energy efficiency measures and renewable energy generation. Building on previous work for the Commission for Environmental Cooperation, Synapse evaluated methods that rely on power system dispatch models and methods that rely on simplifying assumptions to estimate emission reductions. The project objective was to help state and local air officials determine the best method for estimating emission reductions in a given situation, given key characteristics of the local power system and the amount of resources available for this assessment. Project completed in July 2005.
