METRO’s compressed natural gas buses have covered 10 million miles

Natural gas buses are leading the alternative fuels charge against outdated diesel and gasoline fuels whilst reducing the amount of pollutants in the air.


Since 2016, Houston METRO has travelled 10 million miles with their fleet of compressed natural gas (CNG) buses.

The CNG fleet currently includes 50 buses, and will have 20 more by the end of 2018.

In the past two years, METRO has used more than 3 million gallons of CNG, preventing more than 3,000 tonnes of nitrogen oxide (NOx) from entering the air. By adopting clean burning fuels, METRO has greatly reduced the amount of harmful pollutants in the air. Replacing dirty fuels with CNG is the safest and most affordable method for improving air quality.

METRO’s efforts will be greatly appreciated as Houston is currently ranked 11th on the American Lung Association’s list of worst polluted cities by ozone with the high road traffic levels contributing to the high concentration of nitrogen oxide (NOx). The Texas Commission on Environmental Quality (TCEQ) reported that 67 per cent of all NOx emissions come from a mobile source, particularly heavy-duty trucks that run throughout the city.

METRO’s 10 million mile achievement was announced during the NGV America Road Rally by Jim Robinson, First Vice-Chair of the METRO Board. The road rally made 15 stops across the country promoting the use of natural gas as a transportation fuel and educating the public about clean burning alternative fuels. 

Freedom CNG, a developer of natural gas fuelling infrastructure is also helping to improve Houston’s air quality through the promotion of alternative fuels. Freedom encourages the adoption of clean and affordable CNG through education, training, workshops and grant writing support.
