Low carbon Communities

Our “built environment” is a major source of energy consumption. As recently as 2013, our buildings have accounted for 28% of secondary-energy consumption and related greenhouse gases in Canada. This is closely followed by the transportation sector, which accounted for 29% of secondary-energy use, 80% of which was by on-road transportation. Focusing attention on the carbon efficiency of our built environment is key to a sustainable future.

With operating energy demands representing over 90% of a building’s energy use and GHGs over its lifecycle and the environmental burden of road reconstruction, rehabilitation or maintenance, the energy efficiency and durability of concrete buildings and pavements make it the solution of choice for low carbon communities.

Now, a new study by Canada’s renowned International Institute for Sustainable Development finds that up to 72% of carbon emissions from wood products may currently be omitted from wood products LCAs and that when these emissions are taken into account, concrete’s embodied carbon footprint could be up to 6% less intensive than that of wood products.
