New York and the New England states have adopted aggressive greenhouse gas (GHG) emission reduction goals. Deep decarbonization will be required to achieve these goals, and the region has made substantial progress. Emissions from energy use in these seven states in 2015 was 19 percent less than 2001 emissions. However, there’s still a long way to go: the region’s collective objectives will require emission reductions of about 80 percent below 2001 levels. This report examines electrification in detail. We show how electrification can work with efficiency and clean electric supply to drive deep decarbonization.
