The Chicago Area Clean Cities Coalition (CACC) and its member fleets helped to displace nearly 26.5 million gasoline-gallon equivalents of petroleum in 2016, and reduce greenhouse-gas emissions by 230,000 tons.

This represents a 6% increase in fuel savings over 2015 and a 2% improvement in emissions, according to the coalition. Members of CACC include commercial fleets and municipalities throughout the six-county Chicago area.

The coalition made the announcement at the annual Green Drives Conference and Expo. Companies such as UPS, Ozinga, and Alpha Baking Company were featured at the conference as examples of companies that are using cleaner vehicles.

The United States is 92% dependent on petroleum to transport our goods, services and people, according to the U.S. Department of Energy. In 2016, the U.S. imported 3.6 billion barrels of oil at a cost of $154 billion, according to the CACC.

CACC’s membership is comprised of federal, state and local governments, auto manufacturers, dealerships, fuel suppliers, conversion companies, environmental organizations, corporations, small businesses, and individuals.
