Carbon Benefits of Building Conservation in Canada

A new report from the Canadian Association of Heritage Professionals highlights how retrofitting and reusing existing buildings can lower carbon emissions compared to new construction. By focusing on the full life cycle of a structure, the study shows that conserving building fabric reduces construction waste and the high carbon cost of new materials. As Canada's energy grids decarbonize, the emissions from demolition and new building materials become a larger part of the total climate impact. Prioritizing adaptive reuse and targeted performance upgrades offers a practical path to meeting housing needs while reducing the overall environmental footprint of the built environment.
