The EPA has recently announced a proposal to reduce carbon pollution. Specifically the EPA has set state targets for emission rates (the number of pounds of carbon emissions per megawatt hour of electricity produced). A summary of the percent reduction in proposed emission rate by state is below.
Of course, looking at percent reductions loses scale -- which is paramount in this case. If we look at total yearly proposed carbon reductions (in million metric tons) we see the largest reduction is by far in Texas (87 million metric tons per year) with Florida and Pennsylvania following.
