EPRI-NRDC report finds widespread vehicle electrification and a cleaner grid could lead to substantial cuts in GHG by 2050

Green Car Congress

As with the earlier assessment, this study consists of two separate, but related, analyses: greenhouse gas emissions from 2015-2050, and air quality impacts in 2030. In the Lower GHG scenario, in 2050, total emissions for the electricity and transportation sectors could be reduced by 2610 million metric tons relative to 2015 levels.
