Ahead of the COP31 leaders' summit in Antalya, Hardin's commons problem and Ostrom's answer to it suggest the $300bn goal has the same weak point. - Author: Philosopheasy - Tags: World, Explainer, thinker-ostrom Rich countries promised $100bn a year by 2020; OECD figures reported by Down To Earth put 2022 at $115.9bn, and the Center for Global Development says the goal was partly met by relabelling existing development finance. On our reading, the new $300bn pledge for 2035 leaves the same room. ## What did the $100bn pledge deliver? The goal dates from 2009 and was due by 2020, [Down To Earth](https://www.downtoearth.org.in/climate-change/rich-nations-finally-delivered-on-100-billion-climate-finance-pledge-in-2022-finds-oecd-report-experts-flag-issues?ref=philocrux.com) reported in May 2024\. The OECD's figure for 2022 was $115.9 billion for developing countries. [Business Today](https://www.businesstoday.in/industry/energy/story/in-a-first-100-bn-climate-finance-goal-by-developed-nations-breached-oecd-431387-2024-05-29?ref=philocrux.com), covering the same release, called it the first time the goal had been exceeded. Due in 2020, met in 2022, on the OECD's count. The count is where the argument starts. Sehr Raheja of the Centre for Science and Environment was quoted by Down To Earth saying there is “no agreed-upon definition of climate finance”. Rebecca Thissen of Climate Action Network was quoted in the same report: “Loans are again taking the lion's share of climate finance.” The Center for Global Development (CGD) went further. Carbon Brief reported, in a copy on [Eco-Business](https://www.eco-business.com/news/rich-countries-met-us100-billion-climate-finance-goal-by-relabelling-existing-aid?ref=philocrux.com), that CGD concluded the goal was “partly achieved by adding climate objectives to existing development finance flows.” CGD's Ian Mitchell put it bluntly: “rebadging it, which is not providing climate finance.” The distinction matters for the next goal. If a target can be reached by relabelling, the headline number measures bookkeeping as much as money. ## What does the $300bn pledge say? The COP29 text, as [Down To Earth](https://www.downtoearth.org.in/climate-change/cop29-ends-with-300-billion-figure-declaration-but-it-is-public-or-private-finance?ref=philocrux.com) quotes it, asks for money “with developed country Parties taking the lead, of at least USD 300 billion per year by 2035”. The sources are left wide: “From a wide variety of sources, public and private, bilateral and multilateral, including alternative sources.” The same report records a dispute over what the number means. A UNFCCC press statement framed the goal as tripling public finance from the previous $100bn and referred to $1.3 trillion a year by 2035 from public and private sources. Down To Earth reported that the UNFCCC later deleted “public” from its statement. The wording repeats the old design. The lines quoted say who leads and where money may come from. They do not say who checks the count. A goal that welcomes private and alternative sources invites the counting habits CGD described. ## What do Hardin and Ostrom say about a pledge nobody can compel? Garrett Hardin, a biologist, set out the problem in Science on 13 December 1968, in a [copy on the Garrett Hardin Society site](https://www.garretthardinsociety.org/articles/art%5Ftragedy%5Fof%5Fthe%5Fcommons.html?ref=philocrux.com). His herdsman reasons alone: “As a rational being, each herdsman seeks to maximize his gain.” The result for everyone, he wrote: “Freedom in a commons brings ruin to all.” His remedy was not simply a state with a stick. It was “mutual coercion, mutually agreed upon by the majority of the people affected.” He did not pretend it was free. “Every new enclosure of the commons involves the infringement of somebody's personal liberty,” he wrote. A climate pledge has the agreement. The quoted pledge text names who leads, not who checks the count: that is the gap we see. Ostrom's work is the counterpoint, though we meet it only second-hand. Timothy Taylor, writing on the [Conversable Economist](https://conversableeconomist.com/2018/12/18/tragedy-of-the-commons-50-years-later/?ref=philocrux.com) blog, quotes Ostrom and co-authors in 1999: “Both government ownership and privatization are themselves subject to failure in some instances.” He also quotes the textbook summary by McLean and Dye, which says that “those who share in exploiting a common-pool resource can develop their own rules to prevent its overuse.” That second sentence is theirs, not Ostrom's. Read together, Hardin and the Ostrom summaries give one answer to who enforces: the parties themselves, through rules they write. The test is whether the rules exist. The rule that mattered most, what counts as climate finance, was by Raheja's account in 2024 still without an agreed definition. In Hardin's terms the herdsmen settled the number and left each of them to do the counting. The concept breaks at one point. McLean and Dye describe people who exploit a shared resource, whereas donors here are asked to pay in. The atmosphere is a commons only in a looser sense, which limits how much weight Ostrom can bear. ## What is happening in Antalya? COP31 is hosted in Antalya. [Climate Home News](https://www.climatechangenews.com/2026/09/11/turkiye-says-it-has-final-decision-at-cop31-despite-australia-running-negotiations/?ref=philocrux.com) reported in September that Türkiye hosts in the resort city and that Australia's Chris Bowen would act as COP31 President of Negotiations. The leaders' summit is set for 11 and 12 November. Murat Kurum, the COP31 President-Designate, said it “will take place in Antalya, on Türkiye's south coast, on November 11 and 12.” Climate Home News carried the line in [its April report](https://www.climatechangenews.com/2026/04/14/turkiye-sets-cop31-dates-and-appoints-australian-cattle-farmer-as-youth-champion/?ref=philocrux.com) on the dates. ## What is the strongest objection? That nothing was evaded. No donor or OECD statement in our sources makes this case in so many words, but the OECD's own framing supplies it: it counted finance “provided and mobilised”, and the OECD figure, as reported, exceeds the goal. Where no definition of climate finance has been agreed, counting climate objectives inside development finance may sit within the rules as they stood. On this view the $100bn goal was met under the only counting rules anyone had, and calling it relabelling holds donors to a standard that was never written down. That is a fair point: a pledge cannot be judged by rules that do not exist. The defence also proves the point. A pledge cannot be breached if what it covers is undefined, and a pledge that cannot be breached cannot be enforced. Raheja's phrase and Mitchell's phrase describe one fact: the count rests on a definition nobody agreed. The route Ostrom's summarisers describe, rules the parties write themselves, is open to the negotiators. The $300bn text, as quoted, uses it to say who leads and where money may come from, not what counts. Our position: a definition of what counts matters more than the next number. Watch for whether anything that comes out of Antalya says, in so many words, what counts as climate finance. ## Where to read next - [Down To Earth](https://www.downtoearth.org.in/climate-change/rich-nations-finally-delivered-on-100-billion-climate-finance-pledge-in-2022-finds-oecd-report-experts-flag-issues?ref=philocrux.com): the OECD's 2022 figure and the experts' objections. - [Eco-Business](https://www.eco-business.com/news/rich-countries-met-us100-billion-climate-finance-goal-by-relabelling-existing-aid?ref=philocrux.com): the CGD analysis, in a copy of Carbon Brief's report. - [Garrett Hardin Society](https://www.garretthardinsociety.org/articles/art%5Ftragedy%5Fof%5Fthe%5Fcommons.html?ref=philocrux.com): the 1968 essay in full. - [Conversable Economist](https://conversableeconomist.com/2018/12/18/tragedy-of-the-commons-50-years-later/?ref=philocrux.com): Timothy Taylor on the essay at 50 and on Ostrom's reply. - [What Is the Tragedy of the Commons?](https://philocrux.com/answers/what-is-the-tragedy-of-the-commons/): the dilemma Hardin described. - [How to Solve the Tragedy of the Commons](https://philocrux.com/answers/how-to-solve-the-tragedy-of-the-commons/): state, property or self-governance. - [Tragedy of the Commons (Philosophical Definition)](https://philocrux.com/glossary/tragedy-of-the-commons-definition/): the concept in brief.
