California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. Per capita GHG emissions in California have dropped from a 2001 peak of 14.0 Source: California Air Resources Board (ARB). tons per person to 10.7

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

Researchers at Peking University have developed a new methodology to model black carbon (BC) emissions from diesel and gasoline motor vehicles. Black carbon is a key short-lived climate change forcer ( earlier post ) and motor vehicles are important sources of BC in the environment. Credit: ACS, Wang et al. Click to enlarge.

The worst sites in California have demonstrated a 52% improvement in ozone from 1976 to 2010, a 29% improvement in fine particulate matter (PM 2.5 ) from 2001 to 2010, an 84% improvement in carbon monoxide from 1970 to 2009, and a 92% improvement in sulfur dioxide from 1970 to 2009.

Levels of sulfur dioxide, a pollutant emitted largely by power plants, and chemical oxygen demand, a measure of organic pollution in the water, are down even as CO 2 emissions have continued to rise. What they don’t report is PM 2.5 , which has moved to a position of top concern as major pollution events have hit north China.
