Quantifying Air and GHG Emission Reductions from Clean Energy Measures

Basic approaches typically include spreadsheet-based analyses that use emissions factor relationships or other assumptions to estimate reductions. Sophisticated approaches are usually more complex and involve dynamic electricity or energy system representations that predict energy generation responses to policies and calculate the effects on emissions.* 4.2.2 QUANTIFY AIR AND GHG EMISSION REDUCTIONS FROM CLEAN ENERGY MEASURES Once states have developed their baseline emission estimate or business as usual forecast, they can estimate the emissions that are avoided when implementing clean energy measures. Although an emission reduction estimation can be performed independently from a baseline emissions forecast, aligning many of the assumptions in the baseline case and the clean energy measures case is
