Notes: Additions mean any incentive or law that were added to the AFDC, which is usually the same year that they were enacted or brought into force. This count includes legislation that has since expired.
This chart shows trends in enactments of regulations related to alternative fuels and advanced vehicles according to the type of regulation, from 2002 to 2011. The dataset includes regulations enacted by any of the 50 states or the District of Columbia. Visit the Incentives and Laws page for information on federal and state incentives and laws.
Because a regulation may apply to more than one technology type, adding the totals for each row results in counting some regulations multiple times.
Beginning in 2009, regulations pertaining to economic development, fuel use requirements, idle reduction, renewable fuels mandates, and renewable fuels standards were grouped into "Other."
Beginning in 2009, Climate Change Initiatives was counted as its own category. Previously, climate change initiatives had been included in "Other."
Additions mean any incentive or law that were added to the AFDC, which is usually the same year that they were enacted or brought into force. This count includes legislation that has since expired.
