The deadline for feedback on the draft report, which aims to accelerate the adoption of low carbon concrete in construction, is 7 January 2022.
Civil engineers have been called to give feedback on a draft of the Low Carbon Concrete Routemap.
The Green Construction Board Low Carbon Concrete Group (LCCG)'s routemap aims to provide and share knowledge to accelerate the adoption of low carbon concrete in construction.
The public consultation is open until 7 January 2022, after which the group will formally launch the routemap in February 2022. The feedback will also inform any future revisions of the routemap.
As the infrastructure industry works towards a zero-carbon future, the routemap examines the use of concrete, given the amount of carbon dioxide produced from its active component – cement. The typical UK consumption of cement per year is equivalent to the emissions of 7.2 million cars, a figure that highlights the urgency for action.
Low carbon concrete strategies
The routemap sets out its proposals across seven strands, with chapter eight being a summary that includes a timeline for improvements.
The strategies set out in each strand of the document are signposts for a cooperative interaction between science-based technology, available materials, skills, knowledge and approaches to design and delivery that creates an enhanced combined effect.
Chris Newsome, chair of the Green Construction Board, said: “As we aim to build back better in the post-Covid world, we need to work even harder to reduce or eliminate carbon from the assets we seek to construct. This routemap has been created by a wide range of experts, representing a full cross-section of the value chain involved in specifying, designing, constructing and supplying materials for buildings and infrastructure.”
No single 'silver bullet'
The Low Carbon Concrete Group is formed of professionals from the concrete and cement industry, academia, engineers and clients. Brought together by the Green Construction Board in its role as the sustainability workstream of the Construction Leadership Council, the LCCG has been working together since January 2020 with a bias towards action.
The group recently released the report’s executive summary. This highlights the seven strands of knowledge that need to be developed concurrently to reduce the embodied carbon of concrete.
Andrew Mullholland, chair of the Low Carbon Concrete Group, said: “There is no one silver bullet to address carbon reduction in the construction industry. The focus of the routemap is on demonstrating what we can use today in terms of materials, how we can develop better construction methods and how we can utilise clever design approaches, as well as what actions are required and by when to simplify the specification of cement and concrete.”
