China clean-tech exports are about to cut global emissions by roughly the same amount that Brazil produces in a full year, according to a new analysis published this week by Carbon Brief. The numbers land just days before world leaders gather for the COP31 climate summit in Antalya, Türkiye.

The headline numbers

The analysis comes from Lauri Myllyvirta of the Centre for Research on Energy and Clean Air. It estimates that China clean-tech exports in 2026 will avoid around four hundred and fifty million tonnes of carbon dioxide outside China, which is nearly two percent of global emissions beyond its borders, according to the Carbon Brief analysis.

That impact grew twenty-six percent year on year in the first three quarters of 2026, after already jumping thirty-six percent in 2025. Over the full lifetime of the equipment, this year's exports are on track to avoid eight thousand four hundred million tonnes, about what the United States and India emit together in a year.

What is actually being shipped

Solar is the star. China exported solar panels and parts equal to four hundred and thirty-six gigawatts of capacity in 2025, and wind and solar exports in 2026 should generate as much electricity as around one hundred coal plants. Growth in the first three quarters was wild across the board: electric cars and heavy vehicles up sixty-one percent, wind turbines up forty-five percent, batteries up thirty-nine percent, and solar up twenty-two percent.

Two-wheelers matter too. Of the thirty-nine million electric vehicles China exported in 2025, thirty-six million were e-bikes and scooters. If you have seen a cheap electric scooter anywhere lately, there is a good chance it came from this pipeline.

The global south is the big winner

Most of the export value goes to richer countries, but about seventy-six percent of the lifetime avoided emissions land in the global south. South and south-east Asia alone account for fifty-two percent, largely because Chinese solar is replacing power from carbon-heavy grids. India leads the list, and the United States ranks second even with higher tariffs, since American grids are dirtier and sunnier than Europe's.

The tech has also paid for itself fast. Making the equipment released about one hundred and seventy million tonnes in China in 2025, while it avoided three hundred and seventy million tonnes abroad, so the exports pay back their manufacturing carbon in roughly six months.

Why it matters at COP31

China's environment vice-minister Li Gao said China will play a positive and constructive role at COP31, and flagged what he called the new problem of unilateralism and protectionism, according to Carbon Brief's China Briefing. Translation: Beijing wants a trade system that keeps its solar panels and EVs flowing, and these numbers are a strong argument.

Not everyone is cheering. Johns Hopkins professor Jeremy Wallace argues that China seems more focused on fighting tariffs abroad than on speeding up adoption at home, noting that its renewables buildout slowed dramatically in 2026 while new coal power continues to be built. Another China briefing item notes clean sources made up thirty-seven percent of its power in the first three quarters of the year.

Meanwhile the UN's emissions gap report says breaching the one point five degree limit is now imminent and unavoidable, per bne IntelliNews. In that context, cheap clean tech may be one of the few real levers left.

Trade tension is the catch

Western governments worry about Chinese overcapacity crowding out their own industries. The analysis finds that for most technologies, Chinese exports opened new markets rather than displacing other producers, though wind turbines and fuel-burning vehicles are exceptions. It also warns that if China's domestic solar slowdown continues, more panels could be pushed abroad and inflame trade fights.

For countries that want less dependence on China, the takeaway is blunt: they will need to scale up their own factories to meet demand that is clearly not going away. Türkiye's COP31 presidency is also pushing a voluntary electrification goal, which Chinese suppliers would be well placed to serve.

Keep an eye on Antalya from November nine to twenty. Whether China clean-tech exports become a bargaining chip or a shared climate win could shape the whole summit. For more coverage, see our climate coverage and world news.
