  2023 SPM: Introduction and footnote 4; A.1–A.2; B.1–B.7; C.1–C.7. Retain confidence language, reference periods, scenarios and model assumptions. Figures SPM.1–4 and SPM.7 with full captions (PDF pp. 13–14,20,22–24,33–34): interpret legends, uncertainty and response assumptions; do not memorise map values or add independently assessed mitigation potentials. Exclude other figures/tables, technical model derivations and using assessment-era emissions, budgets, policies, costs or finance goals as current observations. B.1 footnote 28 distinguishes sustained warming from an individual year. B.6 footnote 47 supplies CCS/CDR scope; C.3.3 supplies transport lifecycle qualifications.

• AR6 Working Group I: Regional fact sheet Asia (2021) ↗

  2021 regional fact sheet, prose only: Common regional changes bullets 1,2,4,6–8; Asian Monsoons; Tibetan Plateau and South Asia. Retain stated confidence, period and regional distinctions. Exclude maps, other regional inventories and treating the report-era Karakoram observation as a current measurement or universal glacier behaviour.

• AR6 Working Group II: Fact sheet Asia (2022) ↗

  October 2022 fact sheet: Water first paragraph; observed/projected impacts; Food; Energy first paragraph; Cities and Settlements; Cryosphere first paragraph; Adaptation options and Barriers. Read as regional risk assessment, not a prediction for every Indian district. Exclude numerical inventories, migration totals, maps and clinical advice.

• About CCUS (7 April 2021) ↗

  7 April 2021: About this report; How is CO2 transported? opening sentence and transport modes; How can CO2 be used? opening paragraph; How is CO2 stored – and is it safe? first four paragraphs; How does CCUS support carbon removal? definitions. Read with IPCC B.6 footnote 47 for conditions and barriers. Exclude technology-status/plant/cost tables, capture-technology table, current deployment claims and automatic climate-neutrality claims for fuels or bioenergy.

• EV Life Cycle Assessment Calculator Methodology (2024) ↗

  2024 methodology: PDF p. 1 system boundaries; p. 2 Vehicle manufacturing opening sentence; p. 3 Battery manufacturing opening definition; p. 4 battery end-of-life exclusions paragraph; p. 6 Electricity under Fuel production and opening Fuel consumption definition. Exclude material/vehicle tables, chemistry ratios, battery standards, fixed replacement dates, biofuel neutrality and blanket all-EV-emissions-are-upstream sentence. This model omits some lifecycle stages and is limited to passenger-vehicle GHG comparisons; IPCC C.3.3 provides the mitigation assessment.

• India updated first nationally determined contribution, August 2022 ↗

  August 2022 submission: PDF pp. 2–3 (printed pp. 1–2), introduction and goals 1–8; PDF p. 4, net-zero sentence and unchanged-text clarification. Compare the 2030 commitments with the 2015 targets in the Cabinet account. Distinguish emissions intensity from absolute emissions and installed capacity from generation or total energy demand. No achieved-outcome claim.

• India nationally determined contribution 2031–2035, April 2026 ↗

  April 2026 submission: section 3 goals and clarifications, PDF pp. 10–11 (printed pp. 9–10); section 4 state-plan paragraph on PDF p. 11; Annexure A 1(a–b,d–f), 2(a–b) and 3(b), PDF pp. 17–20 (printed pp. 16–19). Study the 2031–2035 period, target metrics, support conditions and reporting.

• India’s Stand at COP-26, 3 February 2022 ↗

  3 February 2022 report of COP26: five Panchamrit announcements and following finance/technology, LiFE and equity paragraphs. Preserve the announcement wording: renewable energy requirements differs from the installed non-fossil electricity capacity metric in the later NDC. Projected-emissions reduction is not an absolute reduction from a stated historic inventory; exclude acclaim and predicted investment benefits.

• Cabinet approves India’s updated nationally determined contribution, 3 August 2022 ↗

  3 August 2022: paragraph beginning Earlier, India submitted and next paragraph beginning As per the updated NDC; final two paragraphs on finance and absence of sector-specific obligations. Compare the 2015 and 2022 target definitions. Exclude employment/export predictions, railway/LED estimates and assertions of realised decoupling.

• National Action Plan on Climate Change, 2008 government explanation ↗

  12 August 2008 explanation: opening launch paragraph; Domestic Action and National Missions sections, mission purposes only. Use as the original eight-mission design, not a current count. Exclude old implementation forecasts, numeric forest-area aims and claims that any energy source has no environmental costs.

• National Action Plan on Climate Change implementation, 24 July 2025 ↗

  24 July 2025 parliamentary reply: opening institutional paragraph; first Green India purpose sentence; DST programme descriptions before spending totals; Solar Mission purpose sentence; NMSA/NICRA purpose paragraph; NMEEE first sentence and FEEP purpose sentence; human-health paragraph through health preparedness and resilient services, excluding state counts/budget.
