ANAHEIM, Calif. — The U.S. left coast will have new, tougher exhaust standards for heavy-duty diesels starting in 2007.
This news came after the California Air Resources Board (CARB) decided on the adoption of a new standard which mirrors U.S. EPA standards also slated to go into in effect at the same time. The standard achieves emission reductions by equipping new diesel engines with exhaust aftertreatment devices.
Emissions for six major pollutants have fallen 29 per cent since 1970, according to the EPA’s recent report, National Air Quality: 2000 Status and Trends Summary. The report specifically tracked carbon monoxide, nitrogen oxide, lead, particulate matter, sulfur dioxide and ozone. The full report is available online at www.epa.gov/airtrends.
