A full decarbonization of the world’s 1,000 most CO2-intensive industrial plants could save around eight billion tonnes of CO2 a year. That is around a third of the reduction required to achieve the 1.5-degree target. This is the result of the „Global Carbon Restructuring Plan“ study presented by management consultancy Roland Berger. The necessary transformation would require investments of between 7.5 and 10.5 trillion US dollars between 2025 and 2050, depending on the technology used. Renewable energies would be the cheapest option.
