One new goal: to cut air pollution at its Mariupol steel plants to meet EU standards by 2025. Metinvest CEO Yuriy Ryzhenkov said at a press conference on Wednesday: “In the last seven years, the pollution levels of Metinvest’s plants in Mariupol have halved.” To cut pollution, Metinvest plans to invest $500 million over the next five years at the company’s 11 iron mining and steel producing units in Ukraine.
