California Leads in Pressing Automakers to Reduce Greenhouse Gas Emissions


A 2002 Cal­i­for­nia law seeks to force automak­ers to cut green­house emis­sions 29 per­cent by 2015. State gov­ern­ments have become impa­tient with the fed­er­al government’s inac­tion on heat-trap­ping gas­es that many sci­en­tists say con­tribute to cli­mate change. The Cal­i­for­nia Air Resources Board con­tends reduc­tions can be achieved large­ly with exist­ing tech­nolo­gies.

Calif rep­re­sents ~10% of new car mar­ket
Green­house gas­es are pri­mar­i­ly released when gaso­line burns dur­ing inter­nal com­bus­tion
2003-MY aver­age fuel econ­o­my of new cars and light trucks sold nation­wide was 20.7 mpg, down from 22.1 1987 high
US EPA recent­ly con­clud­ed it could not reg­u­late car­bon diox­ide under its exist­ing pow­ers because green­house gas was not a pol­lu­tant
