State Laws & Regulations


California Low Carbon Fuel Standard

The Low Carbon Fuel Standard (LCFS) is administered by the California Air Resources Board. Established In 2007 through a Governor’s Executive Order, it uses a market-based cap and trade approach to lowering the greenhouse gas emissions from petroleum-based transportation fuels like reformulated gasoline and diesel. The LCFS requires producers of petroleum-based fuels to reduce the carbon intensity of their products, beginning with a quarter of a percent in 2011 culminating in a 10 percent total reduction in 2020. Air Resources Board LCFS Homepage. LCFS Program Meeting and Workshop Schedule. 


Oregon Clean Fuels Program

The Oregon Clean Fuels Program, approved by the 2009 Oregon Legislature, aims to reduce Oregon’s greenhouse gas pollution by lowering the carbon content of transportation fuel used in the state. In addition to carbon reduction, the Clean Fuels Program helps Oregon reduce the state’s dependence on traditional petroleum fuels. DEQ is currently implementing the program’s first phase, which entails collection of data from fuel importers and producers. Oregon’s Environmental Quality Commission adopted rules for the first phase of the Oregon Clean Fuels program in December 2012 and amended them in December 2013. 


Regional Greenhouse Gas Initiative (RGGI)

RGGI, an initiative of the Northeast and Mid-Atlantic States of the U.S., is the first market-based regulatory program in the United States to reduce greenhouse gas emissions. RGGI is a cooperative effort among the states of Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont to cap and reduce CO2 emissions from the power sector.

Washington Low Carbon Fuel Standard

The Washington Department of Ecology (Ecology) is charged with assessing whether the California Low Carbon Fuel Standard (LCFS) or a modification thereof would best meet Washington’s greenhouse gas emissions reduction targets.
