A review of India’s evolving NDC commitments and the growing health-climate agenda at COP

Over the past decade, India has transformed from a cautious participant in global climate negotiations into one of its most consequential actors, achieving key renewable energy targets five years ahead of schedule and, in March 2026, approving an ambitious new NDC covering 2031–2035. This review traces that journey and examines how the global COP process has simultaneously elevated health as a central pillar of climate action.

A Decade of Rising Ambition

India’s formal climate commitments began in 2015 with the submission of its Intended Nationally Determined Contribution (INDC) ahead of the Paris Agreement. The targets: a 33–35% reduction in emissions intensity of GDP, 40% non-fossil installed power capacity, and a 2.5–3 billion tonne carbon sink, all against a 2005 baseline by 2030, were considered ambitious for a developing economy still grappling with energy poverty.

The 2021 COP26 summit proved a turning point. India announced its “Panchamrit” commitments: 500 GW of non-fossil capacity, 50% renewable energy share, and a net-zero target by 2070. These were included in the Updated First NDC submitted to the UNFCCC in August 2022, which raised the emissions intensity target to 45% and the non-fossil capacity goal to 50%. Crucially, both revisions reflected not aspirational thinking but an already-visible trajectory of overachievement on the ground.

By 2025, India had reached 50% non-fossil installed power capacity; five years ahead of the original 2030 deadline. The 2019 emissions intensity milestone of ~33% had similarly been achieved well ahead of schedule. These outcomes challenge a persistent assumption in climate discourse that developing nations must choose between growth and decarbonisation.

NDC 3.0: The 2031–2035 Framework

India’s newest NDC, approved by Cabinet in March 2026, sets targets for 2031–2035 under the overarching “Viksit Bharat 2047” development vision. The headline commitments are a 47% reduction in emissions intensity of GDP, 60% non-fossil installed power capacity, and a carbon sink of 3.5–4 billion tonnes. The document is explicit about India’s current standing: over 52% non-fossil capacity already achieved, a 36% emissions intensity reduction logged between 2005 and 2020, and a 2.29 billion tonne carbon sink as of 2021.

The NDC’s emphasis on green hydrogen, battery storage, and clean industrial corridors, alongside adaptation priorities such as coastal protection, climate-resilient agriculture, and disaster early-warning systems, signals a more integrated approach to climate governance than previous iterations. It is anchored in the principles of equity, consistently situating India’s ambition within its developmental context and its limited historical contribution to cumulative emissions.

Health Arrives at COP

A parallel and important shift has occurred within the COP process itself. Prior to COP26, health featured at the margins of formal climate negotiations. Since 2021, it has moved steadily toward the centre. At Glasgow, over 50 countries committed to building climate-resilient, low-carbon health systems. COP27 formalised this with the first-ever Climate and Health Ministerial Meeting and the inclusion of health in the Implementation Plan.

COP28 in Dubai (2023) is widely regarded as the defining moment: the introduction of the first dedicated “Health Day” in COP history, and the adoption of the COP28 Declaration on Climate and Health, which addressed heat illness, vector-borne diseases, and mental health, and called explicitly for health to be integrated into NDCs and national adaptation plans. COP29 and COP30 have continued this trajectory, with new financing platforms and accountability frameworks taking shape.

The thematic architecture of this agenda now encompasses health system resilience, the public health co-benefits of emissions reduction (particularly through cleaner air), One Health approaches linking human, animal, and environmental health, and the disproportionate burden borne by the most vulnerable populations. It represents a genuine broadening of the climate policy frame, one that creates new entry points for civil society, public health professionals, and subnational actors.

What This Means

India’s NDC trajectory and the health-climate agenda at COP are, in important respects, two sides of the same story. Both reflect a growing recognition that growing recognition that climate change is not primarily an environmental abstraction but a concrete threat to human lives, livelihoods, and health systems. India’s consistent overachievement on its climate targets offers credible evidence that ambition is achievable; the COP health agenda provides the normative scaffolding to ensure that ambition is directed toward human wellbeing. As NDC 3.0 takes shape, the alignment between these two threads will be worth watching closely.
