Light-duty vehicles
CO2 compliance pathways for EPA MY 2030 light-duty fleet – a case study
How are light-duty cars and trucks expected to meet future EPA fuel economy standards? What level of electrification would be required? Would hybrids play a role? How does one go about calculating it? Here’s a case study attempting to address some of these questions.
U.S. EPA Proposal for MY2027+ Light- and Medium-Duty Vehicles
On April 12th 2023, the U.S. EPA published a proposal to further reduce greenhouse gas and criteria pollutant emissions from light- and medium-duty vehicles beyond model year 2027. Here is a summary of this “multi-pollutant” regulatory proposal.

Understanding the IRA for electric vehicles
In case you are confused by the Inflation Reduction Act in the US and it’s implications for electric vehicle incentives, then you are not alone. It’s an evolving story, and the U.S. Treasury Department is making clarifications to help consumers understand what’s in it for them. The latest revised guidelines expand the list of vehicles which qualify for the $7,500 tax credits. Here’s a summary.
EPA proposes to revise national ambient air quality standard for fine particulates
The US EPA has proposed to revise the annual PM2.5 national ambient air quality standard (NAAQS) from 12 ug/m3 (micrograms per cubic meter) to a level of 9 – 10 ug/m3. See here for a overview on reasons and implications.
Summary of Euro 7/VII proposal – criteria pollutants
The EU Commission has proposed Euro 7 / VII emission standards for light- and heavy-duty vehicles. Here is a quick tabular summary.
