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.

CARB deal with OEM on low NOx, electrification – and H2 ICE ?
California and Truck & Engine Manufacturers have reached a deal on low NOx and electrification targets in the state. This paves the way for more regulatory certainty but the challenges ahead are not diminished.
U.S. EPA Phase 3 Greenhouse Gas Proposal for Heavy-Duty Vehicles
A downloadable summary of the U.S. EPA announced the Phase 3 GHG proposal for heavy-duty vehicles. From 2027 to 2032, 45% reduction in CO2 emissions for light vocational vehicles and 25% for Class 8 sleeper cabs. Over half of light vocational and a quarter of sleeper cabs expected to be ZEVs by 2032.
