California’s historic AB1493 was the first law in the country to tackle the issue of greenhouse emissions from automobiles head on. Under the law, automakers that produced cars and small trucks were required to significantly cut down on greenhouse emissions — 22 percent less by 2012 and 30 percent by 2016. The standards laid the groundwork for national standards, announced in 2012, that require American-made cars and light trucks to average 34.5 mpg by 2016, and the US auto fleet to average 54.5 miles per gallon by 2025.
