California 2017 GHG inventory shows 1.2% total drop from 2016; transportation sector emissions up 1%

Green Car Congress

Emissions from transportation sources were relatively constant from 2002 through 2007, declined through 2013, then increased by 9.0 In-State Hydro, Solar, and Wind Electricity Generation. The transportation sector represents tailpipe emissions from on-road vehicles and direct emissions from other off-road mobile sources. Source: ARB.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Soot could be further reduced by converting vehicles to run on renewable electric power. Providing electricity to rural developing areas, thereby reducing usage of solid biofuels for home heating and cooking, would have major health benefits, he said. These three gases are all greenhouse gases, and ozone is a surface air pollutant.
