The Global Cement and Concrete Association, made up of 40 global cement companies, has announced its ‘2050 Climate Ambition’, which is to make carbon-neutral concrete by 2050, in line with the aims of the Paris Agreement. With the industry producing something like 6-7% of total anthropogenic greenhouse gas emissions, such an ambition is welcome in the fight against climate change, and numerous cement companies are already studying and testing ways of reducing emissions beyond the 19% reduction the industry has already managed per tonne from 1990 levels. A roadmap for meeting the 2050 ambition is currently in development by the GCCA, and is scheduled to be published in the second half of 2021. It is expected to include a focus on eliminating energy-related emissions, the use of carbon capture and storage, and a transition to a circular economy, in which concrete will be recycled and reused during construction.
