Former U.S. President Donald Trump revived his support for the coal industry during a campaign-style rally in Pittsburgh on Tuesday, telling the crowd that the fossil fuel should be referred to only as “clean, beautiful coal.” Trump argued that rebranding the fuel would help the public better appreciate its purported environmental improvements. Trump’s remarks echo his administration’s earlier efforts to ease regulations on coal production and promote technologies such as carbon capture. The comments drew fresh criticism from environmental advocates and some lawmakers, who say the notion of “clean coal” overstates the sector’s progress in reducing emissions.
