Cement Production and Emissions

In 2021, cement production was responsible for 8% of greenhouse gas emissions. While some emissions are unavoidable due to energy needs, others come from the concrete itself. Adding baking soda can reduce these emissions by up to 15% by mineralizing CO2, preventing it from escaping into the atmosphere.
