Cement makes up just 10-15% of concrete, but is almost exclusively responsible for its CO2 emissions. As populations grow and urban development gathers momentum, green cement will make for more sustainable cities, while moving the needle closer to net zero.
After water, concrete is the second most widely-used substance on the planet. It is also one of the world’s biggest carbon offenders, generating 8% of global CO2 emissions annually.
Almost all these emissions come from a single ingredient: cement. Making up just 10-15% of the concrete mix, cement is responsible for 95% of its emissions. The vast majority of this is generated during the production process.
Aubrey Keller, VP, Emerging Technologies Team, Temasek, and Ryan Gilliam, CEO & Co-Founder of materials technology company Fortera, answer your Burning Questions on how scaling a promising technology can bring the industry closer to net zero.
We have a limited period of time to address climate change, so we need to think not only about the solutions that are available, but how fast we can scale them and introduce them into the market so that they are actually moving the needle on reducing carbon emissions.Aubrey Keller, VP, Emerging Technologies Team, Temasek
