摘要: Representing the greenhouse gas (GHG) emissions attributable to plug-in electric vehicles (PEV) in vehicle GHG regulations is complex because of spatial and temporal variation fueling sources use. Previous work has shown that environmental performance PEVs significantly varies depending on characteristics electricity grid how driven. This article evaluates U.S. Environmental Protection Agency's (EPA's) accounting methodology current future standards for new electrified vehicles. The approach employed by EPA their 2017–2025 model year light-duty regulation compared with an mechanism where actual regional sales PEVs, emission factor sold, are used determine compliance value. Changes over time included modeling efforts. A projection a past rule observe effect such regulation. results showed complexity involved tracking PEV will not dramatically increase effectiveness capture electricity-related absence major policy shift. discussion feasibility standard notable examples region-specific instated energy policies, also addressed.
