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.

At a contentious board hearing on May 7, 2021, the South Coast Air Quality Management District (SCAQMD) approved a first-in-the-nation rule to regulate trucking emissions from warehouses by a 9-4 vote. These state and federal standards require areas to reach certain ambient concentrations of ozone to be considered in “attainment.”

Because last week, the California Air Resources Board (CARB) made history by unanimously adopting what is perhaps the most transformative clean trucks regulation ever considered—the Advanced Clean Fleets (ACF) rule. This rule creates the first-ever, economy-wide, zero-emission standard for large truck fleets.

Up until now, the main justification for initiatives to control leaks from oil and gas infrastructure from the wells through the distribution system has been because those leaks contain methane-- a potent greenhouse gas-- and volatile organic compounds-- a precursor to the formation of ozone air pollution.

Several cities in California, including Los Angeles and in the Bay Area, have outlawed new gas hookups, but these are the first regulations that would effectively ban the sale of gas appliances. Additionally, NOx react with other chemicals in the air to create other harmful pollutants, like fine particulate matter and ozone.

Critically, and as we’ll discuss in greater depth shortly, hydrogen combustion (as opposed to its use in fuel cells) also leads to greater emissions of nitrogen oxides (NOx), a toxic group of pollutants regulated under the Clean Air Act. It is also a precursor to other pollutants, including ozone (a key component of smog).
