COMPRESSED NATURAL GAS VEHICLES EMIT AS MUCH AS GASOLINE by politico, March 9, 2016
Cities with fleets of compressed natural gas vehicles tout their reduced climate emissions, but when viewed throughout the fuel life cycle of natural gas, they emit just as much as gasoline buses, and more than diesel, according to a study from Rice University and published Tuesday in the International Journal of Global Warming. The study found that, from a greenhouse gas emission perspective, natural gas would be best used as a replacement for coal-fired power plants and oil-fueled heating furnaces.
