The UK concrete industry has reduced the carbon dioxide emissions per tonne of concrete by 30%
Decarbonising cement and concrete has been a focus for over 30 years, with the UK cement sector reporting on its efforts since the Kyoto protocol in 1990.
A 30% reduction in embodied carbon per tonne of concrete has been achieved due to a range of measures including investment in fuel switching, with both biomass and waste materials, and producing low-carbon cement formulations.
Work is now underway to switch to zero-carbon fuels. In 2019, a BEIS-funded feasibility study found that a combination of biomass, hydrogen and plasma energy could eliminate fossil fuel CO2 emissions from cement manufacturing.
In 2020, a ground-breaking BEIS-funded project will involve trials at sites operated by Tarmac and Hanson Cement, one focusing on electrical plasma energy with biomass, the other on hydrogen and biomass.
