SCS Group, a contractor on the HS2 project, has committed to using net zero concrete by 2050.
Having signed up to the ConcreteZero initiative, the firm has set goals for buying 30% lower emission concrete in 2025, with this rising to 50% five years later before the eventual end goal of no emissions.
The initiative was set up by the Climate Group, with concrete accounting for 8% of global emissions.
By becoming signatories, members commit to lower their emissions and the carbon impact of the materials they buy and use.
Jen Carson from the Climate Group said: “The carbon emissions linked to one of the world’s most used materials needs to be addressed head-on and that this can be done now through a live project.
“SCS sets the bar for the future of all UK infrastructure and shows that it’s not only necessary but entirely possible to limit the carbon emissions linked to concrete today.”
On making the commitment, Athina Papakosta from SCS added: “Joining ConcreteZero is testament to teaming up with the rest of the industry to drive the overarching goal of lower carbon concrete forward.”
