Meeting Environmental Challenges Head-On
Climate change and clean air are important concerns for Canadians and for Canada's cement manufacturers. Understanding that the manufacture of cement is an energy-intensive process, since large amounts of thermal energy are needed to heat the raw materials, Canada's cement producers are serious in moving forward with their strategy to reduce greenhouse gas and air pollutant emissions. This strategy includes efforts to further improve energy efficiency , and the increased use of alternative and renewable energy and supplementary cementing materials.
Greenhouse Gas Emissions and Air Pollutant Emissions Performance
Canada's cement industry accounts for an estimated 1.4% of total Canadian greenhouse gas emissions and 1.0% of total Canadian air pollutant emissions.
The cement industry has achieved significant improvements in its overall emissions performance through major technological advances, capital investments in new processes, and investments in pollution control equipment since the 1970s.
Between 2003 and 2006, the cement industry achieved a further 14% reduction in total SO2 emissions and a 14% reduction in total NOx emissions, while total production increased by 10%. During this same period, the industry achieved a 1.3% improvement its greenhouse gas emissions intensity.
Monitoring and Reporting
All member companies of the Cement Association of Canada measure, monitor and publicly report the air pollutants and greenhouse gas emissions data of each cement manufacturing plant on an annual basis through Canada's National Pollutant Release Inventory and Greenhouse Gas Inventory.
Member companies employ the Cement CO2 Protocol developed by the global Cement Sustainability Initiative to measure and report greenhouse gas emissions.
