How will NGVs help the U.S. meet environmental and energy-security laws?
The Clean Air Act Amendments (CAAA), signed into law in November 1990, contain numerous provisions that affect vehicles the primary source of air pollution in many urban areas. The law includes new emission standards for passenger cars, trucks and buses, as well as off-road engines and vehicles. There also are new requirements for fuels and inspection and maintenance (I/M) requirements for the nation\’s most polluted areas. Although the law does not require automotive manufacturers to produce alternative-fuel vehicles, the number of NGVs in use is increasing measurably because of the law\’s tougher emission standards. The introduction of more expensive emission reduction technologies on gasoline vehicles is expected to make NGVs more economic, since they generally are expected to meet the new standards with little or no major modifications. Laws that focus on vehicle emissions reduction have served to educate millions of Americans on the importance of controlling motor vehicle pollutio
