California’s Renewable Natural Gas Vehicles Turn Carbon Negative in 2020
Vehicles in California running on renewable natural gas removed more carbon dioxide from the atmosphere than they emitted for the first time last year as the carbon intensity of the fuel continues to drop, according to new data from California’s Air Resources Board (CARB) analyzed by an industry trade group.
California adopted measures to decrease the carbon intensity of its transportation sector more than a decade ago, part of a wider scheme to cut greenhouse gas emissions in the state.
The use of renewable natural gas (RNG) in fleets of trucks, buses and other vehicles grew 25% from 2019 to 2020 and is up more than 170% in the past five years, according to the data.
