In July 2025, India announced a climate milestone: 50% of its installed electricity capacity came from non-fossil fuel sources, meeting a 2030 target five years early. Meanwhile in March 2026, coal production passed 1 billion tonnes for the second financial year running. This contradiction exposes a problem with measuring progress; a country can meet its clean energy target while continuing to deepen its dependence on fossil fuels. How should governments judge progress when one policy advances a climate goal but may also serve other economic priorities?
The UN's 17 Sustainable Development Goals (SDGs) offer one answer: a broader vision of progress than economic growth alone. Yet delivery is faltering. In 2026, only 36% of the 139 targets with available trend data were on track or making moderate progress, while 15% had fallen below their 2015 baselines. The UN points to conflict, slowing growth, climate change, rising debt and a record fall in development aid. Together, these pressures mean governments can no longer advance every goal at once; with less money and more crises, they must choose. Yet the framework says little about how. Agreeing on objectives does not tell governments which policies to pursue, and when a policy promises gains in one area and losses in another, governments should explain why they chose it over the alternatives and which trade-offs they accepted.
India’s energy choices show why meeting a target is not the same as settling a policy decision. Non-fossil fuel sources accounted for half of its installed capacity by June 2025, but coal still generated 71% of its electricity that year. Installed capacity measures potential output; actual generation shows which sources supplied the power people used. The milestone therefore leaves open the question on how future demand should be met. Comparing financial costs alone cannot answer that question, because some of coal’s costs never appear on the bill. Coal may be cheap to burn, but its costs extend far beyond the price of electricity. Pollution damages health and the environment, leaving the public to bear the external costs that producers and consumers do not pay themselves.
Counting pollution changes the calculation, but does not finish it. Governments must still compare realistic alternatives that deliver comparable reliability. Cost-benefit analysis offers a way to do this, by weighing each option’s wider consequences rather than financial returns alone. For India, the question then becomes whether additional electricity demand could be met with less overall harm. For the SDGs, the broader lesson is that reporting an improving indicator cannot, by itself, establish that the policy behind it was preferable to its alternatives.
The SDG framework already recognises that goals can pull against each other. Target 12.c, for example, calls for reforming inefficient fossil-fuel subsidies while accounting for environmental impacts and protecting vulnerable communities. Countries also present Voluntary National Reviews to the UN, and the UN’s guidelines for these reviews encourage discussion of trade-offs. The case for reform is therefore not that the SDGs ignore difficult choices. It is that these choices deserve a more structured place in reporting.
The 2027 SDG Summit offers an opportunity to provide one. Governments should agree on a common “trade-off account” within national reviews, beginning with a small number of major policies. Each account should identify the policy’s objective, the realistic alternatives, its effects on other goals, the groups bearing the costs and the assumptions that could change the conclusion. To keep the burden manageable, existing appraisal work should be reused, with support for countries lacking analytical capacity. Reviews would remain country-led, but readers could compare the reasoning behind selected decisions, not just their reported results.
A common format would not prevent every evasion. Governments could still omit awkward decisions or choose flattering assumptions. But it would give researchers, journalists and citizens a clearer basis for challenging what is reported and what is missing.
A trade-off account would not turn politics into arithmetic. An energy policy could produce benefits overall while leaving particular households worse off. A credible account should therefore separate the total balance from its distribution and explain how those left worse off would be protected. It should also disclose how future damage is valued. Coal's benefits arrive now, while much of its climate damage arrives decades later. The discount rate, which converts future costs into today's terms, decides how much that damage counts: at 1%, $100 of harm in 50 years is worth about $61 today; at 5%, barely $9. Effects that cannot credibly be priced should remain visible rather than disappear from the assessment.
The SDGs measure outcomes well, but they say far less about whether the decisions behind them were sound. For India's next coal investment, a trade-off account would ask a concrete question: why choose this option over the alternatives, and who bears the costs? Governments should report not only which goals a policy supports, but which trade-offs they accepted in choosing it, in a form others can scrutinise.
Meeting a target early is worth celebrating. Showing what it cost and why it was worth it is what makes it progress.
