Cement contributes to ~8% of the Earth's CO2 emissions. Almost 4x aviation, and not too far off all of the Earth's combined agriculture.

If concrete was a country, it'd be the 3rd highest polluting country on Earth, after China and the US.

Even if this headline is overly ambitious, any improvement is a good one.
