GS Paper 3 · Tips & tricks

GS-3 — data first, then policy, then a concrete way forward

  1. Open with a number.GDP share, FDI inflow, emissions intensity, forest cover %, fiscal deficit — the right number in the first sentence does the work of a paragraph.
  2. Cite the latest report by name.Economic Survey, RBI Financial Stability Report, NITI Aayog SDG India Index, ISRO mission timeline — examiners can verify, so accuracy is checked.
  3. Use a flowchart for processes.Disaster cycle, ML pipeline, food-processing value chain, cybersecurity kill chain — a small labelled diagram beats prose.
  4. Distinguish stock from flow.Forex reserves vs trade balance, debt stock vs deficit, capacity installed vs energy generated. Mixing them up costs marks.
  5. Way forward must be specific.Not "the government should take steps" — name the ministry, the scheme name, the budget head, the timeline.

Introduction: India submitted updated NDC in August 2022 — 45% emissions-intensity cut by 2030 (vs 2005 baseline) and 50% non-fossil capacity by 2030; LT-LEDS released at COP27 (Sharm El-Sheikh, November 2022); EU CBAM definitive phase from 1 January 2026.

Body: 1) LT-LEDS pillars — low-carbon electricity, transport electrification, urban systems, hard-to-abate sectors, CO2 removal, finance. 2) CBAM impact — covers cement, iron-steel, aluminium, fertilisers, hydrogen, electricity; ~US$8 billion of Indian exports exposed. 3) Domestic instruments — CCTS notified 2023, Green Credit Programme 2023, GH2 mission ₹19,744 crore.

Way forward: Operationalise CCTS compliance phase; negotiate CBAM equivalence via India-EU FTA; scale GH2 to 5 MMT by 2030; ramp climate finance flows; assert CBDR-RC at COP31.

Key points
  • Updated NDC 45% emissions-intensity reduction by 2030 (Aug 2022)
  • 50% non-fossil capacity by 2030; net-zero by 2070
  • LT-LEDS released at COP27 Nov 2022
  • EU CBAM definitive phase 1 Jan 2026
  • ~US$8 billion Indian exports exposed to CBAM
  • Carbon Credit Trading Scheme notified 28 June 2023

Show model answer outline

Introduction: National Clean Air Programme launched January 2019, revised target of 40% reduction in PM2.5/PM10 by 2025-26 over 2017 baseline; CAQM Act 2021 created the Commission for Air Quality Management for NCR and adjoining areas; CPCB AQI 2025 records winter PM2.5 in Delhi at 250-400 µg/m³ against WHO 5 µg/m³ annual.

Body: 1) NCAP — 131 non-attainment cities; ₹10,000+ crore disbursed via 15th FC grants. 2) Airshed governance — CAQM Act covers 5 states; GRAP stages I-IV. 3) Gaps — stubble burning, ULBs under-resourced, slow source-apportionment science.

Way forward: Statutory airshed plans for IGP; expand SAFAR-style real-time monitoring; mandatory crop-residue management with PUSA decomposer; phase out unfit BS-IV trucks.

Key points
  • NCAP launched January 2019, MoEFCC
  • Revised target 40% PM reduction by 2025-26
  • 131 non-attainment cities under NCAP
  • ₹10,000+ crore disbursed via 15th FC air-quality grants
  • CAQM Act 2021 — Commission with statutory powers
  • GRAP stages I-IV trigger by AQI
  • WHO 2021 guidelines PM2.5 5 µg/m³ annual
  • Stubble fires Punjab-Haryana ~30% Delhi winter PM2.5
