Medium- and heavy-duty vehicles (MHDVs), like the big rigs on our highways and the vans that deliver our packages, make up just over 1 in 10 of the vehicles on our roads, but are responsible for over half of ozone-forming nitrogen oxide pollution and lung-damaging fine particulate pollution from on-road vehicles.

It’s clear , and it has been clear for decades, that to stave off the worst impacts of climate change we must drastically reduce greenhouse gas (GHG) emissions. Much of California also continues to be out of compliance with federal air quality standards, and millions of Californians breathe unhealthy air every day.
