The Greenhouse Gas Equivalencies Calculator uses the eGRID U.S. Environmental Protection Agency, Washington, DC. national weighted average CO 2 marginal emission rate, year 2021 data. Regional marginal emission rates are also available on the AVERT web page.This calculation does not include any greenhouse gases other than CO 2.national weighted average CO2 marginal emission rate, year 2021 data) Therefore, AVERT provides a national marginal emission factor for the Equivalencies Calculator. EE and RE programs are not generally assumed to affect baseload power plants that run all the time, but rather marginal power plants that are brought online as necessary to meet demand. A marginal emission factor is the best representation to estimate which fossil-fired units EE/RE are displacing across the fossil fleet. Calculating the emission impacts of EE and RE on the electricity grid requires estimating the amount of fossil-fired generation and emissions being displaced by EE and RE. Most users of the Equivalencies Calculator who seek equivalencies for electricity-related emissions want to know equivalencies for emissions reductions from energy efficiency (EE) or renewable energy (RE) programs. national weighted average CO 2 marginal emission rate to convert reductions of kilowatt-hours into avoided units of carbon dioxide emissions. The Greenhouse Gas Equivalencies Calculator uses the AVoided Emissions and geneRation Tool (AVERT) U.S. To facilitate user reproducibility calculations that use data from WARM, the input data were not modified to reflect GWPs from AR5. These are calculated using GWPs from the Intergovernmental Panel on Climate Change’s Fifth Assessment Report (AR5), except for the equivalencies that are calculated using the Waste Reduction Model (WARM) because the model uses the Fourth Assessment Report (tons of waste recycled instead of landfilled, GHG emissions avoided by recycling X garbage trucks or railcars full of waste, and trash bags of waste recycled instead of landfilled). Go to the equivalencies calculator page for more information.Ī note on global warming potentials (GWPs): Some of the equivalencies in the calculator are reported as CO 2 equivalents (CO 2E).
