Nornickel starts sulphur dioxide capture in Russia's most polluted city
Russian mining giant Nornickel launched a multi-billion dollar project on Wednesday aimed at reducing sulphur dioxide emissions by 45% in Norilsk, Russia's most polluted city, through a complex capture programme. Before Russia sent troops into Ukraine in February 2022, the company had estimated costs at $4.1-$4.3 billion. "Challenges arose when certain international vendors declined to provide vital equipment to Russia," Nornickel said in a statement.
