EPAs GHG Standards for Light-Duty Vehicles; Special Credits To Encourage PHEVs, BEVs and FCVs

Green Car Congress

Source: EPA. As part of its program, EPA is establishing a system of averaging, banking, and trading (ABT) of credits, based on a manufacturer’s fleet average CO 2 performance. Both EPA and NHTSA programs are footprint-based—i.e., g CO 2 /mi (EPA). mpg US (EPA). g CO 2 /mi (EPA). mpg US (EPA).

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

Source of data: US EPA (2019). EPA is targeting implementation in the 2027 timeframe while CARB is focusing efforts on phasing in more stringent standards in 2024 and again in 2027 with the hope of aligning with EPA as a national standard. Chart: MECA.

Ford / AVL study concludes mid-level ethanol blend attractive as a long-term future fuel for use in optimized engines in US

Green Car Congress

Given the properties of the fuel blend, improved fuel efficiencies can be generated by several approaches, including downsizing/downspeeding; increased compression ratio; reduced enrichment; and the leveraging of improved efficiency at part load. Downsizing/downspeeding. benefit in EPA M/H CO 2 and a 3.1% Earlier post.).

ICCT working paper highlights benefits of current and emerging light-duty diesel technology; “promising pathway for compliance”

Green Car Congress

The combined National Highway Traffic Safety Administration (NHTSA) / US Environmental Protection Agency (EPA) fuel economy and greenhouse gas standards for light duty vehicles require an estimated combined average fuel economy of 34.1 The original technology assessments informing the NHTSA/EPA rule are now about 5 years old.

CALSTART survey of major auto suppliers finds 70% don’t want US to change CAFE targets; split on amount of electrification needed

Green Car Congress

When presented with a list of technologies analyzed within a National Academies of Science report ( earlier post ) that might be used to meet fuel-efficiency standards, suppliers picked turbocharging and engine downsizing, along with higher-speed automatic transmissions, as the most critical.

Industry survey finds aluminum use in autos at all-time high; average per vehicle use expected to more than double from 2012 by 2025

Green Car Congress

The report expects aluminum to double its share of the light vehicle material mix by 2025 vs. the 2008 EPA baseline vehicle. Using aluminum will extend the efficiencies of other technologies, while enabling secondary cost-savings from downsized powertrains without sacrificing performance. Ducker Worldwide.
