Discuss India's progress towards its Nationally Determined Contributions (NDCs) under the Paris Agreement. What structural challenges remain in achieving net-zero by 2070?

India's updated NDC (2022) commits to cutting the emissions intensity of GDP by 45% from 2005 levels, reaching 50% non-fossil installed power capacity by 2030, and creating an additional carbon sink of 2.5–3 billion tonnes CO₂e [1] — an equity-based pledge flowing from CBDR-RC. Progress has been uneven: strong on capacity, weaker on sinks and on absolute decarbonisation.

Progress on NDC commitments

• Non-fossil capacity target met early: India crossed the 50% share in 2025, five years ahead of the 2030 deadline, with renewables, large hydro and nuclear together exceeding thermal capacity [2].
• Ambition raised, not relaxed: the third NDC (2031–35) targets a 47% intensity cut and 60% non-fossil capacity by 2035, with a sink of 3.5–4 billion tonnes CO₂e [3].
• The sink leg lags: additional sink created since 2005 remains short of the 2.5–3 billion tonne goal [1], making afforestation the weakest commitment.
• Capacity is not generation: coal still supplies close to seven-tenths of electricity generated, since solar plants run only part of the day [4]. The milestone is real, but it measures machines installed, not carbon released.

Structural challenges to net-zero by 2070

• Coal lock-in: young thermal plants, coal-linked railway freight cross-subsidies and mining-dependent State economies make early retirement costly.
• Grid and storage deficit: variable renewables need balancing capacity, transmission corridors and battery storage at a scale not yet built.
• Finance gap: COP29 fixed only $300 billion a year by 2035 against far larger assessed needs, and without a grant sub-goal, leaving transition costs on domestic budgets [5].
• Hard-to-abate sectors and trade pressure: steel, cement and fertilisers lack commercial green technology, while the EU's CBAM, effective 1 January 2026, taxes their embedded carbon at the border [6].

India's record shows credible delivery on what it promised, even as the harder, emissions-reducing phase lies ahead. Sequencing storage investment, a just transition framework for coal districts, and firm concessional finance and technology transfer can convert early gains into net-zero — honouring both climate justice and Article 48A's constitutional mandate.
