Climate change is the moral examination of our generation

The Intergovernmental Panel on Climate Change, in its AR6 Synthesis Report released on 20 March 2023, issued what its chair Hoesung Lee described as a 'final warning'. The 1.5 degree Celsius threshold of the Paris Agreement is likely to be crossed in the early 2030s, on current trajectories. The carbon budget remaining for a 50 per cent chance of staying below 1.5 degrees is approximately 500 gigatonnes of CO2. Yet that budget is not equally spent. The World Inequality Report of 2022 found that the wealthiest 10 per cent of humanity is responsible for nearly half of cumulative emissions; the poorest 50 per cent for barely 12 per cent. Climate change is not a scientific problem awaiting a technical fix; it is a moral examination of our generation, a test of whether one cohort can hold itself accountable to all those it has not yet met.

The framing is older than the science. John Rawls's veil of ignorance, applied across time rather than across class, asks: what climate policy would we choose if we did not know whether we would be born in 2025 or in 2125? Edmund Burke, that conservative of conservatives, wrote in Reflections on the Revolution in France in 1790 that society is 'a partnership not only between those who are living, but between those who are living, those who are dead, and those who are to be born.' The Atharva Veda, in its Bhumi Sukta, calls the earth 'Mata Bhumih Putroaham Prithivyah', 'the earth is my mother, I am her son.' Religion, philosophy, and constitutional theory converge on the same proposition: the present generation holds the earth in trust, not in fee simple.

The principle of common but differentiated responsibilities and respective capabilities, CBDR-RC, is the legal expression of this moral intuition. UNFCCC Article 3, drafted at Rio in 1992 and reaffirmed in the Paris Agreement of 2015, recognises that historical emissions are not evenly distributed. The United States, with 4 per cent of world population, contributed 25 per cent of cumulative CO2 emissions; the European Union added another 17 per cent. India, with 17 per cent of world population, contributed 3 per cent. India's per-capita emissions stand at 1.9 tonnes of CO2; the United States' at 14.4 tonnes (Global Carbon Atlas 2023). And yet, by Germanwatch's Climate Risk Index 2023, India is among the top three most climate-vulnerable countries on earth, with annual losses of USD 159 billion attributable to extreme-heat impact on labour productivity alone (ILO 2022).

The legal architecture is catching up. The Loss and Damage Fund, debated since the 2007 Bali COP and resisted for fifteen years, was operationalised at COP28 in Dubai in December 2023. Its initial capitalisation of approximately USD 700 million remains symbolic against estimated need exceeding USD 100 billion annually. Vanuatu's UN General Assembly resolution of 29 March 2023, requesting an ICJ advisory opinion on the legal obligations of states to climate-vulnerable populations, was adopted by consensus. The European Court of Human Rights, in Verein KlimaSeniorinnen Schweiz v Switzerland on 9 April 2024, held that Switzerland's failure to adopt adequate climate measures violated Article 8 of the European Convention. The Indian Supreme Court, in M. K. Ranjitsinh v Union of India on 21 March 2024, held that the right to be free from adverse effects of climate change is part of Articles 14 and 21. Climate justice is no longer an aspirational phrase; it is a litigable cause of action.

India's contribution to the moral examination has been substantive. The Long-Term Low Emission Development Strategy was submitted at COP27 in November 2022, charting India's path to net-zero by 2070. The Updated NDCs of August 2022 committed to reducing emissions intensity of GDP by 45 per cent from 2005 levels and to achieving 50 per cent of installed power capacity from non-fossil sources by 2030. Mission LiFE, launched on 20 October 2022, foregrounds individual and community behaviour. The International Solar Alliance, co-founded with France in 2015, has grown to 120-plus member countries. India's installed non-fossil capacity reached 200 GW by mid-2024; the PM Surya Ghar Muft Bijli Yojana of February 2024 targets 1 crore rooftop installations by 2027; the Green Hydrogen Mission of January 2023 targets 5 million tonnes by 2030.

An honest counter-argument deserves a careful answer. Climate action, sceptics say, sacrifices growth in a country where 800 million depend on PMGKAY. The IPCC's AR6 Working Group II report finds that every dollar invested in adaptation saves USD 4-10 in disaster recovery. The Global Commission on Adaptation estimated USD 1.8 trillion in adaptation through 2030 would yield USD 7.1 trillion in net benefits. The choice is not between climate action and growth; it is between calibrated investment now and catastrophic damage later.

What might full implementation look like? The State Action Plans on Climate Change, prepared in 2010-12, need a second-generation update with quantified targets. The Sovereign Green Bond programme should scale toward Rs 1 lakh crore annually. Carbon-trading under the Carbon Credit Trading Scheme of June 2023 needs robust monitoring. The Ranjitsinh judgment must be operationalised through a Climate Adaptation Act with public-trust grounding. School curricula must teach climate literacy under NEP 2020. The 'Polluter Pays' principle must extend to corporate Scope 3 emissions through SEBI's BRSR framework.

The intergenerational nature of climate change is what makes it ethical rather than merely technical. A child born in 2026 will be 76 in 2102, living through the 2.7 degrees Celsius rise projected under current policies. The Bundelkhand household whose monsoon failed thrice in seven years knows climate change as missed wages. The Mumbai sweeper whose May shift crosses the WHO heat-stress threshold knows it as a heart palpitation. The Chamoli family buried by the 7 February 2021 Rishiganga flash flood knows it as a funeral.

Climate change is the rare ethical question that admits no spectators. The atmosphere is the most democratic common in human history; every breath is a vote, and the vote of the future cannot be cast except by us, today. The Bhagavad Gita's lokasangraha, the Atharva Veda's Bhumi Sukta, the Christian doctrine of stewardship, and Rawls's veil of ignorance each meet at this point. The moral examination of our generation is therefore not whether to act but whether to act in time, at scale, with justice. India has begun. The world is watching. The next generation, whose vote we cannot count, will judge us on results, not rhetoric. The exam is one we must pass together, or fail forever.
