GCCA India–NCB Carbon Uptake by Concrete Report

Syllabus: Climate Change & Carbon Sinks

Ministry of Commerce & Industry

Why in news?

Global Cement and Concrete Association (GCCA) India and NCB released a report on CO₂ uptake through carbonation in concrete, highlighting cement industry's potential as a carbon sink.

📌

Prelims-Oriented Points

✦ Cement Industry Emissions: ~7% of total anthropogenic CO₂ emissions globally
✦ Carbonation Process: Concrete absorbs CO₂ over its lifecycle, acting as a partial carbon sink
✦ Methodology: Based on Tier-I methodology of IVL Swedish Environment Research Institute
✦ NCB: National Council for Cement and Building Materials—apex R&D body under DPIIT
✦ Gypsum Board Quality Control Order, 2024: Notified by DPIIT for standardization

⚠️

Examiner's Trap: Cement is a "hard-to-abate" sector due to process emissions from calcination of limestone, not just energy use.

Quick Data Points

Cement Industry: 7% of global anthropogenic CO₂

NCB: 63rd Foundation Day

Mains Value Addition

GS-3: Environment (Climate Change, Carbon Accounting), Science & Technology

Carbon Sink Recognition: If included in NATCOM to UNFCCC, it can offset India's emission inventory
Sectoral Decarbonization: Need for innovation in cement chemistry (e.g., blended cements, alternative binders)
Data-Driven Policy: Robust carbon uptake data can inform climate mitigation strategies
