Green Car Congress

The state’s latest Greenhouse Gas Emissions Inventory shows that California emitted 429 million metric tons of climate pollutants in 2016—a drop of 12 million metric tons, or three percent, from 2015. They fell 23% from a peak of 14 metric tons per person (roughly equal to driving 34,000 miles) in 2001 to 10.8

EIA: US energy-related CO2 dropped 2.7% in 2015; of end-use sectors, only transportation increased

Green Car Congress

Specific circumstances, such as the very warm fourth quarter of 2015 and relatively low natural gas prices, put downward pressure on emissions as natural gas was substituted for coal in electricity generation. Coal’s share of total electricity generation in the power sector fell from 54% in 1990 to 34% in 2015. between 2014 and 2015.
