The decline of coal use in the European Union and United States is overshadowed by surging natural gas and oil use around the world, according to the researchers. About 40% of global carbon dioxide emissions were attributable to coal use, 34% from oil, 20% from natural gas, and the remaining 6% from cement production and other sources.

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.
