Strong community and environmental partnerships lead to workable solutions in Colorado.

The CNG Bus Program was a collaborative effort between Noble Energy and the Regional Air Quality Council to replace diesel-burning school buses with new, efficient buses that run on clean-burning natural gas produced right here in Colorado.

Through the program, we purchased more than 60 buses for school districts in Denver and Greeley to:

  • Reduce noise pollution
  • Reduce pollutants by as much as 45%
  • Reduce fuel expenses

Fuel for the CNG buses is up to one-third less expensive than diesel fuel on an equivalent energy basis. As a result, school districts save approximately $3,000 on fuel per CNG bus per year.

Benefits of our CNG Bus Program

By helping school districts replace old diesel school buses with new ones that run on clean-burning compressed natural gas (CNG), we reduced carbon monoxide and other emissions, while saving our schools millions of dollars.

Some 480,000 school buses carry 25 million children — more than half of America’s schoolchildren — each day, making the school bus industry the largest form of mass transit in the United States.

Noble Energy saw a great opportunity to help create a better future for children by replacing diesel-fueled school buses in Colorado with compressed natural gas (CNG) buses.

Specifically, natural gas vehicles outperform conventional fuels with:

  • A significantly higher-octane rating
  • Better fuel efficiency
  • Lower operating costs
  • Dramatic emissions reductions

Plus, it is the only alternative fuel that can power heavy-duty trucks and buses, the busiest vehicles on the road today. Clean burning natural gas is also responsible for plummeting emissions in the United States, which now stand at 25-year lows according to data from the Energy Information Administration.
