The federal government and companies that produce materials for the construction industry can play a significant role in helping to reduce the amount of carbon that is emitted each year. That’s the bottom line in a report from the Buy Clean Industry Alliance, a coalition of industry associations, think-tanks and labour and environmental groups which includes the Cement Association of Canada and Aluminum Association of Canada. The report, called Building Success: Implementing Effective Buy Clean Policies, lays out recommendations and specific actions the government and industry can take to reduce up to four million tonnes of carbon emissions a year. Actions include using lower-carbon building materials, as well as construction and design practices for publicly procured construction projects. …The construction industry is the focus of the report because production of building materials is highly emissions-intensive, with iron, steel and cement making up almost four per cent of Canada’s greenhouse gas emissions.
