Summary of EPA proposal : Heavy-Duty Clean Trucks Plan

Here’s a summary of EPA’s proposed changes to tailpipe NOx and CO2 emission standards for HD trucks in the US beyond 2027.

California’s Advanced Clean Trucks regulation

This is an update to a previous article on the targets for electrification of heavy-duty trucks in the US. Initially developed in California (where else?!), now five more states have adopted these regulations.

Overview of California’s Advanced Clean Fleets proposed regulation

California’s Advanced Clean Trucks regulation requires an increasing portion of heavy-duty (HD) vehicle sales to be zero emitting, starting 2024. However, a mandate on selling electric trucks will work only if there is a market for these vehicles. That’s the idea behind the Advanced Clean Fleets regulation. Read here for the current elements being considered.

California’s Heavy-Duty Low NOx Omnibus Regulation

California’s Air Resource Board (CARB) has passed what could be perhaps it’s last major regulation for reducing NOx and particulates from heavy-duty trucks and buses. The HD Low NOx “Omnibus” regulation practically touches upon every aspect of in-use emission reduction. Highlights summarized here.
