Working with Parkway School District on their clean energy bus system, Lion CSG helped to provide a compressed natural gas system. In partnership with East-West Gateway Council of Governments, Clean Cities, and Laclede Gas, a grant for $1.5 million in federal highway funding was used to purchase 30 CNG buses and a fueling station. The project will save Parkway an estimated $100,000 per year in fuel costs, as well as reduce the amount of emissions to the environment.
