Key Alternative Fuel and Fuel Economy Legislation

Key alternative fuel and fuel economy legislation date back to the Clean Air Act of 1970 (as amended in 1990), which created initiatives to reduce mobile sources of pollutants. In 1988, federal laws established vehicle manufacturer incentives in the form of Corporate Average Fuel Economy (or CAFE) credits (Alternative Motor Fuels Act). The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) and the Transportation Equity Act for the 21st Century (TEA-21) of 1998 laid the foundation for the highway construction and safety programs. In 1992, the Energy Policy Act of 1992 established regulations requiring federal, state, and alternative fuel provider fleets to build an inventory of alternative fuel vehicles. Subsequently, Congress passed the Energy Policy Act in 2005, which emphasized the use of alternative fuels and the development of supporting infrastructure.

Surface transportation acts include the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA), the Transportation Equity Act for the 21st Century (TEA-21) of 1998, and the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU), enacted in 2005. Each of these acts authorizes funds for highway construction, highway safety, and public transportation programs.

The Energy Independence and Security Act of 2007 introduced provisions to increase the supply of renewable fuel sources and raise CAFE standards to reach 35 miles per gallon by 2020. The Emergency Economic Stabilization Act enacted the Energy Improvement and Extension Act of 2008, and the American Recovery and Reinvestment Act of 2009 appropriated nearly $800 billion towards the creation of jobs, economic growth, tax relief, improvements in education and healthcare, infrastructure modernization, and investments in energy independence and renewable energy technologies. This section summarizes these laws.

American Recovery and Reinvestment Act of 2009

The American Recovery and Reinvestment Act (ARRA) of 2009 (Public Law 111-5) was signed into law by President Obama on February 17, 2009. ARRA appropriates nearly $800 billion towards the creation of jobs, economic growth, tax relief, improvements in education and healthcare, infrastructure modernization, and investments in energy independence and renewable energy technologies. ARRA supports a variety of alternative fuel and advanced vehicle technologies through grant programs, tax credits, research and development, fleet funding, and other measures. Below is a summary of the provisions relevant to the Clean Cities portfolio areas (alternative fuels, advanced vehicles, idle reduction, and fuel economy):

Energy Independence and Security Act of 2007

(Enacted December 19, 2007)
The Energy Independence and Security Act (EISA) of 2007 aims to improve vehicle fuel economy and help reduce U.S. dependence on petroleum. EISA includes provisions to increase the supply of renewable alternative fuel sources by setting a mandatory Renewable Fuel Standard, which requires transportation fuel sold in the U.S. to be a minimum of 36 billion gallons of renewable fuels by 2022 including advanced and cellulosic biofuels as well as biomass-based diesel. In addition, the law requires the Corporate Average Fuel Economy (CAFE) standard for passenger cars and light trucks to reach 35 miles per gallon by the year 2020. In addition, EISA includes grant programs to encourage the development of cellulosic biofuels and plug-in hybrid electric vehicles and other emerging electric technologies, and the inclusion of electric drive vehicles under EPAct 1992. The law is projected to reduce greenhouse gas emissions by 9% by 2030. For more information, see the EISA summary table. For the full text, see the EISA link.

Energy Policy Act of 2005

(Enacted August 8, 2005)
The Energy Policy Act (EPAct) of 2005 called for the development of grant programs, demonstration and testing initiatives, and tax incentives that promote the production and use of alternative fuels and advanced vehicles. EPAct 2005 also amended existing regulations, including fuel economy testing procedures and EPAct 1992 requirements for federal and state and alternative fuel provider fleets.

Energy Policy Act of 1992

(Enacted October 24, 1992)
The Energy Policy Act (EPAct 1992) of 1992 aims to reduce U.S. dependence on imported petroleum and improve air quality by addressing all aspects of energy supply and demand, including alternative fuels, renewable energy, and energy efficiency. EPAct 1992 encourages the use of alternative fuels through voluntary and regulatory activities and approaches carried out by the U.S. Department of Energy (DOE). Voluntary activities are implemented through Clean Cities, and EPAct 1992 regulations require that link federal and state and alternative fuel provider fleets build an inventory of alternative fuel vehicles. EPAct 1992 also defines "alternative fuels" as methanol, ethanol, and other alcohols; blends of 85% or more of alcohol with gasoline (E85); natural gas and liquid fuels domestically produced from natural gas; liquefied petroleum gas; hydrogen; electricity; biodiesel (B100); coal-derived liquid fuels; fuels, other than alcohol, derived from biological materials; and P-Series fuels, which were added to the definition in 1999. Under EPAct 1992, DOE has the authority to add more alternative fuels to the list of authorized alternative fuels if certain criteria are met. For more information, visit the EPAct Web site.

Clean Air Act Amendments

The Clean Air Act Amendments (CAAA) of 1990 amended the original Clean Air Act (CAA) of 1970. The CAAA of 1990 created several initiatives to reduce mobile source pollutants, thereby pursuing one of the original goals of CAA. CAAA establishes standards and procedures for reducing human and environmental exposure to a range of pollutants generated by industry and transportation. Each state is required to develop a state implementation plan that explains how it will carry out initiatives outlined by CAAA. The U.S. Environmental Protection Agency (EPA) assists states by providing scientific research, expert studies, engineering designs and funding to support clean air programs.

Surface Transportation Acts (ISTEA, TEA-21, SAFETEA-LU)

The national surface transportation acts authorize funds for highway construction, and highway safety and public transportation programs. The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) and the Transportation Equity Act for the 21st Century (TEA-21) of 1998 laid the foundation for the highway program. ISTEA established the Congestion Mitigation and Air Quality (CMAQ) Improvement Program, which provides funding for projects and programs in air quality non-attainment and maintenance areas to reduce transportation-related emissions. TEA-21 continued the CMAQ program and established the Clean Fuels Grant Program, which allows transit systems to apply for and receive grants to purchase or lease clean fuel buses, related equipment or facilities, and use biodiesel. The Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) was enacted in 2005. SAFETEA-LU continued and amended several programs established under ISTEA and TEA-21, such as CMAQ and the Clean Fuels Grant Program. SAFETEA-LU also established additional programs and incentives related to alternative fuels, advanced vehicles, and fuel efficiency, including the Alternative Fuel Excise Tax Credit, the High Occupancy Vehicle (HOV) Lane Exemption, and the Idle Reduction Facilities Regulation in Interstate Rights-of-Way program.

Alternative Motor Fuels Act

(Enacted October 14, 1988)
The Alternative Motor Fuels Act (AMFA) created vehicle manufacturer incentives in the form of Corporate Average Fuel Economy (CAFE) credits for the production of motor vehicles capable of operating on certain alternative fuels (electricity, liquid petroleum gasoline, and biodiesel are not included). AMFA also directed the U.S. Department of Transportation, in consultation with the U.S. Environmental Protection Agency and the U.S. Department of Energy (DOE), to conduct a study and submit a report to Congress evaluating the success of the policy decision to offer CAFE credit calculation incentives for dual-fuel vehicles. The report, Effects of the Alternative Motor Fuels Act CAFE Incentives Policy, was submitted to Congress in March 2002. The AMFA fuel economy provisions were extended by the Automotive Fuel Economy Manufacturing Incentives for Alternative Fueled Vehicles Rule of 2004.

AMFA required that an alternative fuels education and data resource center be created. As a result, the Alternative Fuels and Advanced Vehicles Data Center was established in 1991 at DOE's National Renewable Energy Laboratory.
