Low Carbon Cement In the production of cement, CO 2 is emitted through fossil fuel combustion and through a chemical reaction of the raw materials. Because cement is used widely as a construction material, its production contributes significantly to global warming. In Phase 1 of the project, EPFL in collaboration with partner institutions in Cuba and India conducted extensive research on a new cement type (LC 3 ) which emits 10-30% less CO 2 emissions compared to commercially available cements. Phase 2 of the project aims at preparing the grounds for large-scale production of the new cement by the industry, with a particular focus on India and Cuba.
