Switzerland/UAE: The COP28 UAE Presidency named École Polytechnique Fédérale de Lausanne (EPFL) among its Energy Transition Changemakers in the Heavy Emitting Sectors category. EPFL won the prize for its LC3 limestone calcined clay cement, which replaces 50% of clinker content with calcined kaolinite clay and limestone. LC3 cement reduces CO2 emissions by 40% compared to ordinary Portland cement (OPC), and is a readily available solution that can be scaled worldwide. EPFL noted the special importance of LC3 cement for CO2 reduction efforts in developing countries, and sees it as having the potential to eliminate 500Mt/yr of global CO2 emissions by 2030. In a post to LinkedIn, the LC3 Project said that nine plants around the world currently produce LC3 cement, with a further 20 planned before 2025.
