Forty cement and concrete companies from around the globe have unveiled a joint industry effort to deliver carbon neutral concrete by 2050.

The initiative, called the 2050 Climate Ambition, is being co-ordinated by the Global Cement and Concrete Association. It aims to reach its targets through reducing and eliminating energy-related emissions, reducing process emissions through new technologies, more efficient use of concrete, recycling of concrete and other methods.

Adam Auer, vice-president of environment and sustainability for the Cement Association of Canada, outlined the progress Canada has been making and what can be done to accelerate carbon reduction.

Auer noted because the solutions and technology for cement around the world are roughly the same, the key difference between countries is their regulatory environment, policy and the ambitions of government to achieve climate goals.
