On Friday, we demonstrated together with Fridays for Future Heidelberg and other movements against the extensive use of cement as a building material. According to police reports, around 800 demonstrators took part despite the cold and rain. Cement is viewed critically as a building material because its production releases about four times as much CO2 equivalent as international air traffic. Thus, this production process causes about 8% of global CO2 emissions.
