- It takes less energy to produce concrete than it does to produce steel or wood according to a study conducted by the National Ready-Mixed Concrete Association and reported by the World Business Council for Sustainable Development.
- The production of cement – the primary ingredient of concrete – is responsible for 1.5% of Canada’s CO2 emissions, compared with 3% for the forest industry.
- Given the costs and challenges of shipping concrete, most concrete is produced very close to where it will be used. This reduces the need for fuel for transportation.
- Concrete is highly reflective. A high percentage of the light that hits concrete roads and walls is reflected, thereby helping to keep cities cooler and reduce the need for air conditioning.
- Heat moves very slowly through concretewalls and floors, thereby reducing swing in indoor temperatures.
- The industry increasingly uses waste products to the replace some of the conventional cement required in the production of concrete.
- The concrete industry has made important progress in its use of alternative fuels.
- The longevity and stability of concrete means that it requires less maintenance and it is rarely replaced.
