Goal: Reduce volatile organic compound (VOC) and fine particle emissions

According to the U.S. Environmental Protection Agency (EPA), the installation of diesel oxidation catalysts can reduce VOCs by 50%, carbon monoxide by 40% and particulate matter by 20%. The Clean School Bus project involved a consortium of partners, including 14 Wisconsin school districts (six in Dane County) and five private bus companies in southern and central Wisconsin, that installed diesel oxidation catalysts in 253 school buses. The Madison Metropolitan School District (MMSD) was the project leader in partnership with Dane County Clean Air Coalition and the EPA's Clean School Bus USA program.

DCCAC and EPA also partnered with the Middleton-Cross Plains School District to provide the same retrofit service to its publicly-owned school bus fleet and to Denmark School District's fleet in Brown County.
