Rice study finds using natural gas for electricity and heating, not transportation, more effective in reducing GHGs

MARCH 9, 2016

Rice University researchers have determined a more effective way to use natural gas to reduce climate-warming emissions would be in the replacement of existing coal-fired power plants and fuel-oil furnaces rather than burning it in cars and buses. However, residential uses and exports of natural gas were not considered in those comparisons.
