Electric vehicles fall foul of upstream emissions

摘要

If electric utilities could offer advice to US federal regulators setting greenhouse gas emissions standards for vehicles, it would be to stick to measuring exhaust from the tailpipe. The rule finalized by the US Environmental Protection Agency to target GHG emissions from the transportation sector takes a hybrid approach when it comes to vehicles that are fueled by the power grid and not the gasoline pump. That, the electric utility's trade association believes, could stunt the growth of electric vehicle fleets.
