China is the world’s biggest polluter, and also, increasingly, its biggest supplier of the equipment that cuts pollution. A new analysis puts a number on the second half of that paradox: in 2026, China’s exports of solar panels, wind turbines, electric vehicles and batteries will help the world avoid 450 million tonnes of carbon dioxide emissions outside China — roughly the same as Brazil’s entire annual emissions from burning fossil fuels.
The analysis comes from the Centre for Research on Energy and Clean Air (CREA), a Finland-based research organisation, and was reported by Reuters ahead of next month’s COP31 climate summit. The avoided emissions equal about 2% of the world’s annual emissions outside China, and they are growing: last year’s figure was 370 million tonnes, already more than the United Kingdom emits from fossil fuels in a year.
The bulk of the benefit lands in the Global South. Countries there have sharply increased imports of Chinese clean technology and are using it to clean up fossil-heavy power grids — many of them in sunny regions where solar power, by far the biggest source of avoided emissions among the exports, works best. The analysis also accounts for the other side of the ledger: manufacturing the panels, turbines and batteries emits carbon too, but the report estimates it takes only around six months for a clean-tech import to “pay back” its manufacturing emissions.
Two caveats matter. First, “avoided emissions” are modelled estimates, not tonnes measured at a smokestack — they depend on assumptions about what power generation the imports displace. Second, none of this changes China’s own position as the world’s largest overall emitter of carbon dioxide, even as the United States remains the biggest per-capita emitter and the biggest historical producer of greenhouse gases.
Why this matters anyway: the climate debate often treats China as a single number — its domestic emissions. The export story complicates that picture in a useful way. The cheapest solar panels in history are being made in China, and they are decarbonising grids in countries that could never have afforded the energy transition at European prices. As negotiators head to COP31, that tension — the world’s largest emitter as the world’s largest enabler of emission cuts — will sit at the centre of arguments about who pays, who benefits, and who gets blamed. The 450-million-tonne figure will not settle those arguments. It does reframe them: the energy transition is no longer something only rich countries export. Increasingly, it arrives in a shipping container from China. The stakes are visible in this year’s record heat deaths.
