The U.S. is expected to reach a major carbon emissions milestone this year: For the first time, carbon dioxide emissions from burning natural gas in the U.S. are set to surpass those from burning coal — the globe’s chief climate polluter.
Emissions from burning natural gas are expected to be 10 percent greater than those from coal in 2016, as electric companies rely more on power plants that run on natural gas than those that run on coal, according to U.S. Department of Energy data.
