How concrete could become a surprising climate solution – BBC News

Could one of the world’s most destructive materials become part of the solution to the climate crisis?

After water, concrete is the second most consumed material on the planet, with a colossal 30 billion tonnes used each year.

It has a serious emissions problem though, accounting for more than 8% of all greenhouse gases in 2021.

However, innovative new technology could offer a way to revolutionise the construction industry, creating new forms of concrete that actively capture and store CO2.
