The Environmental Impacts of Concrete Greenspec
• Production of one tonne of cement results in 780 kg of CO2 • Of the total CO 2 output 30% derives from the use of energy and 70% results from decarbonation • Important to realise is that although 5% of the worldwide generation of CO 2 is due to cement production that level of output also reflects the unique and universal importance of concrete throughout the construction industry
