Diesel Retrofit Project in China
The U.S. Environmental Protection Agency, the Beijing Environmental Protection Bureau (EPB) and China's State Environmental Protection, Administration (SEPA), kicked off a diesel retrofit demonstration project in Beijing on November 10, 2005.

The project will entail installation of emissions control equipment on 25 - 30 city buses in Beijing, many of which will use low-sulfur fuel in combination.

Air pollution in China is increasing rapidly, much of it due to the rising number of vehicles. In Beijing alone, close to 1,000 vehicles are being added to the roads each day. The fine particulate matter and other emissions from existing diesel-powered trucks and buses contribute to air pollution in Beijing and other large cities and pose serious public health impacts.

At least two different technologies will be demonstrated: one that can reduce particulates by as much as 30 percent; and a second that when used with low-sulfur fuel, can reduce particulates by 90 percent or more. A successful retrofit demonstration project will lay the groundwork for expanded retrofits of heavily polluting vehicles in Beijing. This will have a positive impact on air quality in Beijing, and thus public health, as the city prepares for the Olympics in 2008 and beyond.

EPA has committed $200,000 and staff time to the diesel retrofit demonstration project. Through a cooperative agreement, the Southwest Research Institute will manage the project in Beijing, working closely with EPA, Beijing EPB, the bus company and the emissions control vendors. SWRI is contributing matching funds to the project.

Because new vehicle technologies and the most effective retrofit technologies depend on clean fuels, EPA and SEPA agreed to work together to reduce fuel sulfur levels as one of an integrated array of projects in China for clean fuels and vehicles. Other projects under this agreement include compliance management, training, and advanced vehicle technologies.

Several other partners have also committed to join in one or more of these collaborative projects in China, including the Energy Foundation China, Harvard University, Tsinghua University, Cummins, Corning, and others.
