India Cement Sector Footprint and Challenges for Net Zero Target
Source:The Hindu ↗
ఇది ఎందుకు ముఖ్యం
Understanding the challenges in hard-to-abate sectors like cement is crucial for evaluating India's industrial decarbonization strategies and its long-term path to net-zero emissions by 2070.
సారాంశం
The article explores how India's large and expanding cement footprint poses a critical hurdle to achieving its net-zero emissions target by 2070. It highlights the technological, energy, and structural challenges involved in decarbonizing hard-to-abate sectors like cement amidst rising infrastructure demand.
ముఖ్య అంశాలు
- India's massive cement industry footprint presents a significant challenge to achieving its 2070 net-zero emissions target.
- Cement production is inherently carbon-intensive due to the calcination process and fossil fuel reliance for heat.
- Decarbonizing the cement sector requires shifting to alternative fuels, improving energy efficiency, exploring carbon capture and storage (CCS), and promoting blended cements.
- Balancing rapid infrastructure growth and urbanization with stringent climate commitments remains a core policy challenge for India.

Why is the cement industry classified as a hard-to-abate sector under climate change frameworks?
- Calcination Chemistry: Process emissions, accounting for roughly half of total cement emissions, arise inherently from the chemical calcination of limestone (CaCO3 to CaO and CO2).
- Thermal Energy Demand: High-temperature kilns traditionally require the combustion of fossil fuels (coal or petcoke) to reach temperatures exceeding 1400°C.
- Technological Limitations: Unlike power generation, renewable electricity alone cannot fully eliminate process emissions without technologies like Carbon Capture and Storage (CCS).
