- It’s 7% of global emissions, just cement. So finding alternatives is not just an edge case, it’s kind of one of the main things that we need to do.
- Cement is made by heating limestone — the process releases carbon dioxide: Limestone + heat → calcium + CO₂
- For every 1 ton of cement, about **1 ton of Carbon dioxide is emitted.
- China and India together produce more cement than the rest of the world combined — and China alone makes about seven times more than India.
