Question
The cement industry contributes approximately what
percentage of global CO₂ emissions, as highlighted in the CCU collaboration?Solution
The cement sector contributes nearly 7% of global CO₂ emissions, which is why Carbon Capture and Utilisation (CCU) technologies are being promoted to reduce emissions.
