🕰️ PYQ · UPSC Prelims 2025 Consider the following statements : Statement I : Studies indicate that carbon dioxide emissions from cement industry account for more than 5% of global carbon emissions. Statement II : Silica-bearing clay is mixed with limestone while manufacturing cement. Statement III : Limestone is converted into lime during clinker production for cement manufacturing. Which one of the following is correct in respect of the above statements? (a) Both Statement II and Statement III are correct and both of them explain Statement I (b) Both Statement II and Statement III are correct but only one of them explains Statement I (c) Only one of the Statements II and III is correct and that explains Statement I (d) Neither Statement II nor Statement III is correct

🗞️ UPSC DAILY CA · 8 Oct 2026 · The Hindu · p.7 📌 India's cement footprint stands in its way to net-zero emissions 🧩 GS3 · Environment & Ecology › Climate Change 🔥 Must-read · 🎯 Prelims + Mains · 💡 Static Hook ⚡ Crux in one line Cement is hard to abate: about 60% of its CO2 comes from calcining limestone, not fuel. India emits 0.62 t CO2 per tonne of cement and output may rise nearly fivefold by 2070. Options include refuse-derived fuel, lower-clinker blended cements, public procurement of green cement, traditional lime binders and, finally, carbon capture. ❓ Why UPSC cares Industrial decarbonisation and net zero 2070 are GS3 climate themes; cement and fly ash facts are asked in Prelims (2025, 2015). 📚 Static link-up ▸ Calcination: CaCO3 to CaO + CO2 at about 1,450 °C ▸ Clinker (calcium silicates) mixed with gypsum = OPC (>95% clinker); PPC (fly ash, 65-80% clinker); PSC (slag, 35-64% clinker) ▸ Pozzolana reacts with calcium hydroxide ▸ Net zero by 2070 (Panchamrit, COP26) ▸ Carbon Credit Trading Scheme 2023 covers cement. 📊 Numbers to remember Construction: 35-40% of global GHG. Cement: 7-11% of emissions (about double aviation). Heating: 35-40% of cement emissions; clinker 53-65%. India: 0.62 t CO2/t cement; TERI-GCCA target 0.56 (2030), 0.51 (2047). Production 334 MT (2019-20) to 1,546 MT (2070). NITI: 20% RDF thermal substitution by 2030 (~80 MT CO2e saved). Replacing 1 t clinker avoids 0.83 t CO2 (IEA). 🔑 Prelims keywords clinker · calcination · hard-to-abate · RDF · PPC · PSC · lime-surkhi · green cement · CCUS 🕰️ PYQ connect — UPSC Prelims 2025 · GS Paper I UPSC has already asked this theme.
