India's Updated Climate Targets: What the New NDC Commits to and Why It Matters

India's updated Nationally Determined Contributions are notable for what they do and do not commit to. They raise targets where India has already overperformed, set realistic new goals, and make the case for equity in climate responsibility. They do not commit to absolute emission reductions — a position India has consistently defended by pointing to its per capita energy poverty and developed countries' failure to honour climate finance commitments.

Emissions intensity is the amount of greenhouse gas emitted per unit of GDP produced. A 47% reduction from 2005 levels means that India's economy produces 47% less carbon dioxide equivalent per rupee of economic output in 2035 than it did in 2005. This allows absolute emissions to rise as the economy grows while the carbon efficiency of each unit of activity improves. India has achieved a 36% reduction already — the gap between 36% and 47% represents the additional decarbonisation effort committed for the next decade.

India's current non-fossil fuel share of installed power capacity is 52.5%, already exceeding the Paris target of 50% by 2030. The new 2035 target of 60% is set against a more difficult energy backdrop — the West Asia conflict has raised energy import costs, making reliability arguments for some fossil fuel retention stronger. For exam purposes, distinguish between installed capacity (what power plants can theoretically generate) and actual generation (what they produce) — India's renewable generation share is around 20%, much lower than the 52.5% capacity share.

India's carbon sink target — 3.5-4 billion tonnes of CO2 equivalent by 2035 — will be achieved through forest cover expansion and afforestation. The Ministry of Environment, Forest and Climate Change tracks forest cover through the biennial State of Forest Report published by the Forest Survey of India. Concerns about including commercial plantations in the carbon sink calculation are ecologically valid: plantations store carbon but do not replicate the biodiversity, water regulation, or livelihood functions of natural forests.

The SHANTI Act of 2025 amended India's nuclear liability legislation and the Atomic Energy Act to allow private sector participation in nuclear power generation, with FDI up to 49% permitted. The liability clause was brought in line with international practice — the previous framework placed unlimited liability on equipment suppliers, deterring foreign firms from participating. The target of 100 GW of nuclear capacity by 2047 requires adding over 90 GW in roughly two decades, which is only achievable through private investment at scale.

India's National Green Hydrogen Mission, launched in 2023, aims to produce five million tonnes of green hydrogen annually by 2030. Green hydrogen is produced by electrolyzing water using renewable electricity — zero-carbon at the point of production. The challenge is cost: green hydrogen currently costs three to five times as much as hydrogen produced from natural gas. Achieving cost competitiveness requires both cheaper renewable electricity and cheaper electrolysis equipment, both of which are improving but not yet at scale.
