Environmental Rules Played Minor Role in Coal’s Decline

Environmental and climate regulations that cut pollution from coal-fired power plants have played only a minor role in the decline of the coal industry, which has been hurt mainly by expanding use of natural gas and less demand for electricity, according to a Columbia University report published this week. U.S. coal use fell by about 30 percent between 2011 and 2016. The paper attributes about half of that decline to low natural gas prices, 26 percent to falling demand for electricity and 18 percent to growth in renewable energy such as wind and solar. Only 3.5 percent of the coal industry’s decline is due to environmental and climate regulations that took effect prior to 2016.
