Nippon Steel’s US Steel acquisition raises decarbonization cost concerns 

Nippon Steel could risk increasing its decarbonization costs by acquiring US Steel. An activist shareholder group has urged the company to consider the takeover’s impact on its climate goals. 

In 2023, Nippon Steel, the world’s fourth-largest steelmaker, announced a $15 billion takeover bid for US Steel. While US Steel supported the bid, the move has faced opposition from a strong labour union and the White House.
