Climate change is the central issue of our time. In order to meet the agreed greenhouse gas reduction targets of the Paris Climate Change Convention, immense efforts are required, which must be tackled as soon as possible. Now, the structure for a sustainable world has to be developed in which it is possible to do business in a climate-neutral and competitive way. The project SCI4climate.NRW will contribute significantly to this process. The project builds the scientific part of the IN4climate.NRW initiative, a group of the basic materials producing industry (steel, cement, chemicals, aluminum, paper, glass) and energy transporting infrastructure providers (gas, electricity) in North Rhine-Westphalia. The primary goal: identification of the most suitable transformation process and selection of the most appropriate technology therefore towards a climate-neutral and sustainable basic materials industry in 2050 - while maintaining economic efficiency and competitiveness.
