The Environmental Protection Agency (EPA) is finalizing the federal greenhouse gas (GHG) emissions standards for passenger cars and light trucks for Model Years (MY) 2023 through 2026. EPA is planning to initiate a separate rulemaking to establish multi-pollutant emission standards under the Clean Air Act for MY 2027 and later.

The US Department of Transportation’s (DOT) National Highway Traffic Safety Administration (NHTSA) and the US Environmental Protection Agency (EPA) issued a Notice of Intent (NOI) to begin developing new standards for greenhouse gases and fuel economy for light-duty vehicles for the 2017-2025 model years.

IEA fuel economy readiness index status, 2010. New propulsion systems requiring new fuels, such as plug-in electric vehicle systems and fuel cell systems, are beyond the scope of this technology roadmap and are treated in separate roadmaps.

Greenhouse gas and fuel economy levels under the EPA NHTSA joint proposed rulemaking. These standards would require these vehicles to meet an estimated combined average emissions level of 250 grams/mile of CO 2 in model year 2016. NHTSA is proposing CAFE standards for passenger cars and light trucks under 49 U.S.C.

Their TWP approach extends the standard GWP calculation in two ways: by combining the effects of CH 4 and CO 2 emissions from technology-fuel combinations and by considering streams of emissions in addition to single pulses. Reductions in CH 4 leakage are needed to maximize the climate benefits of natural gas.

Since it can refuel from a standard household outlet and from a gasoline station, it needs no new infrastructure. If PHEVs became the major form of transportation, the use of fossil fuels would be cut dramatically. As biofuel becomes a greater percentage of the total fuel mix, less fossil fuel is used.
