The 1,000 most CO2-intensive industrial plants in the world could save around eight billion tons of CO2 annually if they were to be fully decarbonized and thus help maintain the 1.5-degree limit on global warming. Depending on the technology, this transition would require investments of between 7.5 and 10.5 trillion US dollars between 2025 and 2050 and would deliver around a third of the necessary reduction in greenhouse gases. This is the result of the „Global Carbon Restructuring Plan“ study presented by management consultancy Roland Berger.
