California’s Transportation Emissions Drop While Its Economy, Population Grow

Greenhouse-gas (GHG) emissions continue to drop in California even as the state grows its economy and population. Although transportation accounts for the largest chunk of the state’s GHG emissions, data from the California Air Resources Board (CARB) shows emissions already dropping in that sector.

Since 2001, GHG emissions per person have dropped 19% in California, according to data from CARB. While the state’s carbon pollution per million dollars of California gross domestic product (GDP) has declined 33% since 2001, its GDP has grown 37% between 2001 and 2015.
