California’s fleet of commercial trucks and buses is responsible for an outsized impact on air quality and climate change. As currently drafted, the ACF would require that all new drayage trucks be zero-emissions after 2024, and only zero-emissions trucks will be able to perform drayage operations after 2035.

For example, home deliveries in some areas may cut climate-warming emissions compared to driving in a personal vehicle to purchase items in person. Even when accounting for pollution from electricity generation, electric trucks can significantly reduce air pollution and get us on a better track to addressing climate change.

These fees and programs were established with legislation in 2007 and then were extended until 2024 with the passage of Assembly Bill 8 in 2013 (hence the name, “AB 8 fees”). 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.

The California Air Resources Board (CARB) is currently considering one of the most critical rules for air quality and climate change in many, many years. Despite their low numbers, these trucks are responsible for around one-third of smog-forming nitrogen oxide (NOx) emissions, a quarter of lung-damaging fine particulate matter (PM2.5)

These parts have three high-level impacts: Increasing electric truck purchase requirements for large commercial, federal, state, and municipal fleets, beginning as early as 2024 and ramping up to a 100-percent zero-emission fleet requirement in 2042, based on vehicle category. A full transition to electric drayage truck operations in 2035.

The Advanced Clean Fleets (ACF) rule has the potential to significantly reduce climate-warming greenhouse gas (GHG) emissions as well as harmful air pollutants like fine particulates (PM2.5) and nitrogen oxides (NOx) from the numerous commercial and government fleets of MHD vehicles in the state.

Zero-emission trucks were hardly considered viable just a few years ago, but now heavy-duty electric trucks – think semis, delivery vans, and other large commercial vehicles – are beginning to hit the roads and are poised to deliver significant benefits for clean air, climate change, and fleet operators.
