Next 10 report finds California must increase GHG reductions to 4.9%/year through 2030 to meet target

Green Car Congress

This year’s Index finds that 2018 greenhouse gas emissions—the latest year for which data are available—rose overall for the first time since 2012, driven in part by increases in the power and commercial sectors. Data from the report illustrate that California now must reduce emissions by an average of 4.9%
