With $700,000 in funding secured by Congressman Roy Blunt, the city of Springfield has sought to establish a centralized CNG fueling station within its borders. Their rationale is that CNG is a clean burning (improves engine life), high octane fuel that produces 60%-90% less smog producing pollutants and 30%-40% less greenhouse gas emissions than either gasoline or diesel fuels and, thus, allows for cleaner air to breathe.
