Germany’s most CO2-intensive industries are iron and steel production, followed by cement and lime production and the chemical industry. This is the conclusion of the „Dirty Thirty“ study published by the Öko-Institut and WWF. 30 industrial plants together account for 8 percent of total CO2 emissions in Germany. ThyssenKrupp’s steel mill in Duisburg alone emitted almost eight million metric tons of CO2 in 2022. Overall, the industrial sector accounted for a quarter of Germany’s greenhouse gases in 2021.
