A central piece of President Trump’s executive order Tuesday nixes the federal government’s use of the obscure “social cost of carbon” calculation, ending an Obama-era experiment that put an official price tag on greenhouse gas emissions.
The metric, first established in 2010 by an interagency working group that consulted with scientists and others outside government, examined how carbon pollution would impact public health, food crops, infrastructure and a host of other parts of American life. The figure, which now stands at about $40 per ton of carbon, according to the latest federal figures, was a key way in which the Obama administration tried to financially justify its ambitious climate change agenda. The Environmental Protection Agency would, for example, claim that a given program, rule or regulation would save billions of dollars by cutting emissions, and it arrived at those estimates partly by using the social cost of carbon.
