GHG emissions from surface transportation decreased by 4.1% (or 5.3 MMTCO2e) from 2022 to 2023 despite rising VMT. The surprising drop in emissions came primarily from the heavy-duty vehicles subsector, where emissions declined by 17.2%.
GHG emissions from surface transportation per capita decreased by 4.5% during the same period.
In 2023, VMT in California totaled 316.6 billion miles, up 0.4% (or 1.4 billion miles) from 2022, but 9.2% below the 343.9 billion miles recorded in 2018.
In 2023, emissions per VMT averaged 0.39 tons of CO2-equivalent per 1,000 vehicle miles traveled. Not only is this ratio the lowest it has ever been, but it is also 8% less than the 2015 to 2019 average.
From 2022 to 2023, VMT per registered vehicle increased by 0.3% (30 miles) to 10,160 miles.
The vehicle ownership rate (excluding ZEVs) continues to drop precipitously, reaching a new low of 69.5% in 2024.29
For the first time, the number of ZEVs registered (1,899,831) exceeded the number of hybrid vehicles registered (1,758,070) in 2024.
In 2024, the share of new registrations from light-duty pickup trucks, mini-vans, and SUVs reached a new height, breaking 70% for the first time, making up 72.7% of new light duty vehicle registrations—up from 69.4% in 2023.
In 2024, total light truck registrations increased from 1.22 million vehicles to 1.23 million vehicles (+4.4%) while car sales dropped 10.9% from 539,900 to 480,900—less than half a million for the first time.
Together, new BEV and PHEV registrations totaled a quarter (25.5%) of new vehicle registrations in 2024.
At current trajectory, California is not on track to meet its immediate interim Advanced Clean Cars II (ACCII) goals of new ZEV sales at 35% for model year 2026.
In 2024, new battery electric vehicle (BEV) registrations totaled about 387,000 vehicles, a mere 1.2% growth from the 383,000 new vehicles registered the previous year.
Californians registered slightly over 60,000 new PHEVs, the highest figure since 2018 (64,600 vehicles) and the highest market share thus far (3.5% of new registrations in 2024).
