California Passes Nation's Toughest Regulations to Cut Diesel Pollution From Over the Road Trucks

New Legislation Will Require Retrofitting of Over 230,000 Existing Big Rigs

STWA's ELEKTRA™ Product Can Cost-Effectively Reduce Emissions and Improve Fuel Economy While Boosting Performance

MORGAN HILL, CA--(Marketwire - December 18, 2008) - Save The World Air, Inc. ("STWA") (OTCBB: ZERO) reported today that the State of California has unanimously approved legislation that will require the retrofitting of more than 230,000 diesel rigs beginning in 2011. The Air Resources Board stated that the health benefits outweigh the potential financial implications for trucking company owners and operators.

Air Resource Board Chairman Mary Nichols said, "This regulation will save more than 9,000 lives and reduce the toxic emissions that cause cancer and birth defects."

Cecil Bond Kyte, Chairman of Save The World Air, Inc., commented, "The legislation that was just passed is the most comprehensive in the Nation to our knowledge." He added, "We have developed relationships with California State government officials that are leading the way in environmental regulation and reform, and we plan to meet with them over the coming months to discuss how our technology may be one potential solution for trucking companies and independent owner/operators."

According to the State, the regulation is expected to cost trucking companies and independent operators approximately $5.5 billion. California will offer about $1 billion in subsidies, but those subsidies will come with conditions and restrictions.

Kyte added, "We believe that our products offer a low cost alternative for retrofitting diesel truck engines that may allow many of the targeted vehicles to achieve the emissions standards they need to meet. Our products are designed to reduce emissions and save fuel. That means that they pay for themselves and increase the profits of the end user as well as help to solve environmental air quality and energy efficiency issues."
