When world leaders gather at COP climate summits, India is invariably in an uncomfortable position. Its current annual CO2 emissions place it third globally, after China and the United States. Its per-capita emissions are roughly 1.9 tonnes CO2 equivalent per year – a fraction of the United States (14.7), Australia (15.4), or Saudi Arabia (18.4). Its cumulative historical emissions since industrialisation are minimal compared to Europe and North America. And yet India is expected, by many in the international climate conversation, to accelerate its transition away from fossil fuels at a pace that may conflict with its development goals. The “60 billion tonnes” figure in this article’s title refers to a rough estimate of the CO2 debt – the excess emissions that rich nations have pumped into the atmosphere above a globally equitable level since industrialisation began – that the Global South is owed in the form of climate finance, technology transfer, and accommodation for its own development trajectory. This is the climate equity argument that India makes, inconsistently, at international forums.
Historic vs Current: The Emissions Accounting Debate
The climate equity argument begins with an accounting question: who caused the problem? The current concentration of CO2 in the atmosphere – approximately 421 parts per million, up from 280 ppm pre-industrial – reflects cumulative emissions since roughly 1850, when systematic fossil fuel use began at scale. On a cumulative basis, the United States has emitted more CO2 than any other nation in history – approximately 22 percent of total historical emissions. The European Union collectively accounts for another 17 percent. China, despite being the world’s largest current emitter, accounts for about 11 percent of historical emissions. India accounts for approximately 3 percent of cumulative historical emissions, despite having nearly 18 percent of the world’s population.
This historical accounting matters because the stock of CO2 in the atmosphere, not the current annual flow, determines the warming we experience and the climate risks we face. Countries that industrialised first and built their wealth through fossil fuel use have a disproportionate historical responsibility for the climate crisis. Countries that industrialised later – including India, most of Africa, and Southeast Asia – face a fundamental inequity: they are being asked to forego the development pathway that rich nations used, or to pursue an alternative pathway that is currently more expensive, while receiving inadequate financial compensation for doing so.
India’s Coal Reality
Coal provides approximately 70 percent of India’s electricity. About 800 million Indians have access to electricity today – a dramatic improvement from 20 years ago – and that electricity comes overwhelmingly from coal-fired power plants. The plan to triple renewable energy capacity by 2030 (240 GW of solar by 2030, as India committed at COP26) is real, and India has made extraordinary progress in solar deployment – becoming the world’s third-largest solar market. But renewable energy growth is not fast enough to replace coal while simultaneously meeting the growing energy demand of an economy developing at 6-7 percent per year. India added roughly 15 GW of coal capacity in 2022-23, the highest single-year addition in a decade. These are not signs of bad faith in the climate commitment; they are signs of the genuine difficulty of energy transition at scale for a country where energy poverty is still a recent experience for hundreds of millions of people.
The coal sector also employs approximately 3 million people in mining, transport, and power generation – a politically organised constituency in states like Jharkhand, Chhattisgarh, West Bengal, and Odisha. Any serious coal phase-down requires a “just transition” programme for these workers and communities that provides alternative livelihoods, retraining, and economic development support. The loss-and-damage fund established at COP27 was specifically designed to provide resources for transitions of this kind. The climate finance pledged by rich nations to developing countries – the $100 billion per year commitment made at Copenhagen in 2009 and still not fully met as of 2023 – was supposed to fund exactly these transitions. India’s argument at every COP is consistent: give us the money and technology to transition, and we will transition. Without adequate finance, expecting rapid coal phase-down means asking India to pay for a problem it did not primarily cause.
| Country | Per-Capita CO2 (tonnes/year) | Cumulative Share (%) | Coal in Energy Mix |
|---|---|---|---|
| United States | 14.7 | ~22% | ~20% (declining) |
| Australia | 15.4 | ~1.2% | ~48% |
| China | 8.0 | ~11% | ~61% |
| India | 1.9 | ~3% | ~70% |
| UK | 5.6 | ~5% | <2% (phase-out near complete) |
| Germany | 8.1 | ~4% | ~26% (phasing down) |
Solar Rhetoric vs Reality
India’s solar success story is real and significant. From a negligible base in 2010, India has built approximately 73 GW of installed solar capacity by 2024, with aggressive targets for further expansion. The cost of solar power in India has fallen dramatically – from over 15 rupees per unit in 2011 to under 2.5 rupees per unit in recent auctions. India has ambitious plans for green hydrogen, offshore wind, and pumped hydro storage. Prime Minister Modi has personally committed India to 500 GW of non-fossil fuel electricity capacity by 2030. At COP26 in Glasgow, India committed to net zero by 2070 and to meeting 50 percent of energy needs from renewables by 2030.
The solar narrative, however, obscures some less comfortable realities. A significant portion of India’s solar panels are imported from China, creating both a supply chain vulnerability and a current account problem. The domestic manufacturing capacity for solar modules and cells is growing but remains well below the scale needed for India’s own targets, let alone ambitions to be a solar exporter. The grid infrastructure to absorb large quantities of variable renewable power – storage systems, smart grids, transmission lines – is not being built at the pace required. And coal’s share of the electricity mix has been remarkably sticky: it was approximately 70 percent in 2015 and is approximately 70 percent in 2024, because renewables have largely met incremental demand growth rather than displacing coal generation. Genuine coal replacement requires firm commitments to retire existing coal plants on a schedule, which has not been made.
The Loss-and-Damage Argument
At COP27 in Sharm el-Sheikh in 2022, developed nations for the first time agreed to the principle of a “loss and damage” fund – financial compensation for climate impacts that developing countries are already experiencing and cannot adapt to. This was a significant diplomatic achievement, advocated by India, the G77 group, and particularly the small island developing states that face existential climate risk. The fund was formally operationalised at COP28 in Dubai in 2023, with initial pledges of approximately $700 million from a coalition of countries. Climate economists estimate that loss and damage requirements for developing countries will run to hundreds of billions of dollars annually by mid-century. The gap between $700 million pledged and hundreds of billions needed is the climate finance gap in one number.
India’s climate diplomacy has been sophisticated in framing these arguments but inconsistent in its domestic policy alignment. At international forums, India argues for equity, historical responsibility, and adequate finance. Domestically, it has expanded coal capacity, weakened environmental clearance requirements in some sectors, and made minimal progress on coal phase-down commitments. This inconsistency is not unusual among large emitters – the United States did not ratify the Kyoto Protocol; Australia has repeatedly walked back climate commitments. But it does weaken India’s moral authority when it makes the equity argument. The argument is substantively correct; it would be more persuasive if India’s own policy showed greater ambition on the emissions trajectory it controls.

The Equity Argument for a Slower Transition
India’s climate negotiators have consistently argued that developing countries need accommodation for a longer transition timeline, and that the burden of rapid transition cannot be placed on countries that have the least responsibility for the problem and the least resources to manage the transition costs. This is not an argument against climate action – India is genuinely investing in renewable energy at significant scale. It is an argument about the pace and finance of transition, and about who pays. The carbon budget concept – the total amount of CO2 the world can emit while limiting warming to 1.5 degrees – gives India a legitimate claim to a larger share of remaining global emission space than it would get under pure proportional allocation, precisely because it has historically used a smaller share.
The counterargument is that every year of delay in global emissions reduction makes the eventual transition more costly and more disruptive, and that the countries that will suffer most from warming – including India, given its geography and dependence on monsoon agriculture – have the strongest interest in rapid global action. Both arguments have force. The resolution lies in genuine international burden-sharing: rich nations actually delivering the climate finance and technology transfer they have promised, so that India and other developing countries can transition at the pace that global climate targets require without bearing the full cost themselves. That financial compact has not yet been honoured.
Why This Debate Matters to India
India’s climate vulnerability is among the highest of any large economy. Agriculture employs nearly half the workforce and depends heavily on monsoon regularity. Coastal cities including Mumbai, Chennai, and Kolkata face sea-level rise risks. Heat stress is already affecting labour productivity in many states. The climate equity argument India makes internationally is substantively correct – but it does not protect Indians from the physical consequences of warming that will intensify regardless of where responsibility lies.

The Indian Ocean and Monsoon Agriculture Vulnerability
India’s climate vulnerability is not abstract. Agriculture employs approximately 42 percent of India’s workforce and directly affects the livelihoods of over 600 million people. Indian agriculture is heavily dependent on the South Asian monsoon, which delivers approximately 80 percent of annual rainfall in 4 months. IPCC projections suggest that the monsoon will become more intense but also more variable under warming scenarios – more rainfall concentrated in fewer, more extreme events, interspersed with longer dry spells. For farmers without irrigation infrastructure, this variability is potentially catastrophic. The 2022 heatwave that struck wheat crops in Punjab and Haryana, causing yield losses of 10-15 percent in some districts, is a preview of conditions that will become more frequent.
Sea-level rise is also a present and accelerating threat. The Sundarbans, the world’s largest mangrove delta shared between India and Bangladesh, has been losing islands to rising seas for decades – Lohachara Island disappeared entirely in 1996. Mumbai’s sea-front is vulnerable to a combination of sea-level rise and more intense cyclonic storms. Chennai and Kolkata face similar risks. The $100 billion climate finance promise made by rich nations was specifically intended to help countries like India adapt to climate impacts that are already occurring and will intensify regardless of future emissions reductions. The loss-and-damage argument India makes at COP is about paying for the consequences of warming that is already locked in. India’s per-capita emissions do not make it innocent of climate impact, but they do make the equity argument for compensation from high-historical-emitter nations compelling.

The Glasgow Pledges: What India Committed and Where It Stands
At COP26 in Glasgow (November 2021), India made four commitments, sometimes referred to as the “Panchamrit”: reach 500 GW of non-fossil fuel power capacity by 2030; meet 50 percent of energy requirements from renewables by 2030; reduce projected carbon emissions by 1 billion tonnes by 2030; reduce the carbon intensity of the economy by 45 percent (relative to 2005 levels) by 2030; and reach net zero by 2070. The 2070 net zero target, well beyond the 2050 or 2060 targets of most major economies, was immediately criticised by European diplomats and climate groups as insufficiently ambitious. India’s negotiators defended it as consistent with equity principles and development needs. Progress on the nearer-term targets has been mixed: renewable energy capacity has grown strongly, carbon intensity reduction is on track, but the 500 GW target requires a pace of installation over 2024-2030 that exceeds anything achieved so far.
