Designing buildings with low carbon materials can slash cement emissions by 40%.
That’s according to a report by the World Economic Forum (WEF), Boston Consulting Group and the Global Cement and Concrete Association, claiming that systemic changes are needed in the way we construct our buildings.
Cement is to blame for 7% of the world’s greenhouse gas emissions – and the study states that focusing on decarbonising this vital product could be the answer in the net zero question.
This 40% emissions reduction can be achieved by 2030, the research says – by implementing blends of lower carbon cement and by being more efficient and strict on the amount of materials needed to make a building.
Carbon assessment practices need to improve, the study stresses – as currently many buildings are not held to clear enough guidelines surrounding carbon levels.
Government must bring about supportive policy to help decarbonise construction, with a focus also in place for project buyers to consider green credentials when bidding or procuring properties.
“No one player can achieve the necessary actions alone. Scaling low carbon design will take action and collaboration across the built environment value chain. Now is the time for public and private sector leaders to act,” the WEF said.
