"California’s largest greenhouse gas polluters, from power plants to oil refineries to chemical manufacturers, produced slightly fewer emissions last year than the previous year, federal data shows. But it’s still too much planet-warming gas to cut significantly into the problem of climate change, environmentalists say.
Three of the five biggest carbon emitters in the state were in the Bay Area, according to the Environmental Protection Agency’s 2022 data on large polluting facilities. All three were refineries in the East Bay, where the process of turning crude oil into gasoline, jet fuel and other high-demand petroleum products creates substantial greenhouse gas discharges — even before the fuels themselves are used in vehicles or planes.
The refineries were among 367 large stationary sites in California that collectively reported 93 million metric tons of carbon pollution last year, a decline of about 1% over 2021, according to the data. The facilities produce about a quarter of the state’s total human-generated greenhouse gases, which does not include wildfires. Cars and trucks remain the biggest source of carbon emissions."
