Avoided Emission Rates Generated from AVERT
AVERT uses a peer-reviewed methodology to analyze electric power sector impacts on an hour-by-hour basis, but it can also produce approximations of marginal emission rates for each AVERT region. EPA has used AVERT to produce marginal emission rates for each AVERT region and a weighted average for the nation each year from 2007 to 2021. These emission rates can be used for quick estimates of avoided NOx, SO2, CO2, PM2.5, VOCs, and NH3 emissions and are divided into six categories: onshore wind, offshore wind, rooftop-scale photovoltaic, utility-scale photovoltaic, portfolio energy efficiency, and uniform energy efficiency.
