Found out the concrete industry is a massive carbon source and it blew my mind

I was reading a report from the Global Cement and Concrete Association last week and learned that cement alone makes up about 8% of global CO2 emissions. I figured it was bad for the environment but not that bad. Anyone else run into surprising numbers like this?

Nah @lily_sullivan82, those blended cements can make the concrete weaker over time so it's not a real solution.

The 8% number hit me hard too when I first saw it. I started using blended cements with fly ash or slag for my own projects and it cuts emissions by like 30-40%. It's not a total fix but it's something we can do right now without waiting for new tech.
