Canada

Buildings are the third-largest source of greenhouse gas emissions in Canada. In many cities, including Vancouver, Toronto and Calgary, buildings are the single highest source of emissions.

The recently launched Infrastructure for Good barometer, released by consulting firm Deloitte, suggests that Canada’s infrastructure investments already top the global list in terms of positive societal, economic and environmental benefits.

In fact, over the past 150 years, Canada has built railways, roads, clean water systems, electrical grids, pipelines and communication networks to connect and serve people across the country.

Now, there’s an opportunity to build on Canada’s impressive tradition by creating a new form of infrastructure: capturing, storing and sharing the massive amounts of heat lost from industry, electricity generation and communities, even in summer.
