Concrete: the most destructive material on Earth, and one we need to use less of, not more. To make concrete, you need cement. Cement is responsible for about 8% of the world's CO2 emissions – if the cement industry were a country, it would be the third largest emitter in the world.

The Mineral Products Association – the trade body representing Aggregate Industries and friends – wants us to have other ideas, and in a sign that perhaps the industry is beginning to feel the heat, has launched UK Concrete "to provide a voice for the concrete industry":
It is time for the features and benefits of concrete to be recognised and valued together with the commitments the industry is making to support the transition to a net zero carbon society by 2050. Part of our new role will be to highlight the progress the industry is already making to lower concrete's carbon footprint, through the development of materials that allow us to build faster and more cost effectively, and showcasing the benefits of using concrete for a sustainable built environment throughout the UK.
LafargeHolcim – parent to Aggregate Industries – is the largest cement company in the world. Despite commitments, LafargeHolcim’s gargantuan carbon footprint continues to rise – as readers will know. Hardly surprising then that LafargeHolcim was targeted last week by Extinction Rebellion in Paris.

Amazingly lax attitudes towards collusion in the construction industry— David Price (@DavidPriceCN) February 26, 2020
- 1 in 3 think price fixing with rivals is ok 👍
- 1 in 4 think it’s ok to discuss bids with rivals and agree who should win 🤝
(And they still can’t make a good margin!) https://t.co/TY6Ph88so2
