Q&A: Why cement emissions matter for climate change ...

If the cement industry were a country, it would be the third largest emitter in the world. In 2015, it generated around 2.8bn tonnes of CO2, equivalent to 8% of the global total – a greater share than any country other than China or the US.. Cement use is set to rise as global urbanisation and economic development increases demand for new buildings and infrastructure.
