Environmental Impact of Cement Production

Cement production is a major contributor to global CO2 emissions, surpassing those from airplanes, ships, and long-distance trucking combined. The process involves heating limestone, which requires fossil fuels, and results in the release of CO2. For every ton of cement produced, nearly a ton of CO2 is emitted. The video explores whether there are viable alternatives to cement that do not release CO2.
