In interviews, environmental activists working to reduce greenhouse gas emissions say the merger would bring together two steel giants that are laggards on transitioning away from fossil fuels.
Researchers at Industrious Labs, a nonprofit pushing to decarbonize steel and other heavy industries, drew on both companies’ public disclosures to calculate that Nippon and U.S. Steel are relatively high emitters of heat-trapping gases from steel production. Both companies rely heavily on coal-powered blast furnaces and are on a slower path to transition to cleaner fuels than some international competitors. Three U.S. Steel facilities — in Pennsylvania, Indiana and Illinois — combine to emit more greenhouse gases in a year than a comparable number of coal-fired power plants, the researchers estimate.
Officials from Nippon and U.S. Steel say they are pursuing multiple strategies to decarbonize by 2050, including high-grade steel production in more efficient electric-powered furnaces and using hydrogen-injecting technology in blast furnaces, and that their merger will advance those efforts.
In a joint statement on Thursday, the companies said that the deal would “create a stronger, more competitive global company” and that Nippon and U.S. Steel “recognize that solving sustainability challenges is a fundamental pillar of a steelmaker’s existence and growth.”
