China's Clean Technology Exports Shift Climate Action From Aid to Trade

Cheap equipment is changing who can afford clean energy

China's clean technology exports in 2026 are on course to help avoid about 450 million tonnes of carbon dioxide emissions a year once the equipment is deployed, roughly equivalent to Brazil's annual emissions from fossil fuels. Much of that benefit would reach developing countries buying affordable solar panels, batteries, wind turbines and electric vehicles.

The estimate, from Lauri Myllyvirta, lead analyst at the Centre for Research on Energy and Clean Air and a senior fellow at the Asia Society Policy Institute, puts a number on a growing shift: countries can increasingly buy equipment that reduces their dependence on fossil fuels rather than wait for international climate assistance.

China's clean technology exports surpassed $220 billion in 2025. Its factories account for about 85% of global solar supply chain production capacity and 80% of lithium-ion battery capacity. Nearly 75% of electric cars manufactured worldwide in 2025 were made in China.

China's industrial strength is now a central issue at COP31, the United Nations climate conference running from November 9 to 20, 2026, in Antalya, Turkey. Developing countries want affordable technology, while competing manufacturers want protection from imports. Beijing is seeking discussions on the free flow of green technology as tariffs and geopolitical tensions complicate trade.

China also arrives with a contradiction: it supplies much of the equipment helping other countries reduce emissions, yet remains the largest greenhouse gas emitter. Its expanding coal fleet and cautious domestic targets sit alongside rapid growth in renewable energy.

How commercial sales compare with climate finance

An earlier estimate put Chinese clean technology exports and investment in developing countries at $132 billion, including about $40 billion in direct investment by Chinese companies. The investment estimate came from Mathias Larsen and Xiaokang Xue of the London School of Economics.

The $132 billion figure was close to the $137 billion that wealthy countries provided to poorer nations in climate finance in 2024. The comparison captures the scale of Chinese commercial activity, although the money serves different needs.

Chinese transactions mainly pay for equipment and projects expected to earn revenue. International climate finance also supports activities such as protecting agriculture, preparing for floods and recovering from storms. Many of those needs offer little prospect of a commercial return.

Wealthy countries' financial commitments grew from a 2009 United Nations agreement to help developing nations respond to climate change. Much of the support has arrived as loans rather than grants, including lending at market interest rates. Borrowers must repay that money, adding costs to already stretched public budgets.

Lower equipment prices create another route to action. A household, company or government may choose solar power or electric transport because it saves money on electricity or imported fuel. Climate finance still has a separate task: helping countries and communities pay for needs that equipment sales alone cannot meet.

What the emissions estimates actually measure

Myllyvirta's analysis projects that equipment exported in 2026 could avoid 8.4 billion tonnes of carbon dioxide over its operating life, compared with 6.8 billion tonnes for exports in 2025 and 5 billion tonnes for those in 2024. The calculation uses export volumes, manufacturing emissions and the energy sources displaced in importing countries.

The annual estimate of 450 million tonnes covers destinations worldwide. Earlier estimates put annual savings in the Global South at 257 million tonnes for one year's exports and 337 million tonnes for the following year's shipments. The newer analysis extends the period and geographical scope.

Manufacturing the equipment also releases carbon dioxide. For exports in 2025, the analysis estimates about 170 million tonnes of emissions during production in China, against 370 million tonnes avoided abroad annually once deployed. At that rate, the equipment would offset its manufacturing emissions in roughly six months.

The lifetime calculations assume 20 years of operation for solar and wind equipment, 10 years for cars and batteries, and five years for electric vehicles with two wheels. Actual savings depend on installation, use, operating life and the electricity or fuel replaced. The final quarter of 2026 is projected from growth during the first three quarters.

China's Ministry of Commerce has offered a broader historical figure, saying Chinese wind and solar exports reduced global carbon dioxide emissions by about 4.1 billion tonnes over five years. That ministry figure covers several years of equipment use, while Myllyvirta's annual estimate concerns the output of a single year's exports.

Solar panels deliver the largest share of savings

China exported solar panels and intermediate products equivalent to 436 gigawatts of generating capacity in 2025, alongside 8 gigawatts of wind turbines. A gigawatt measures how much power equipment can produce at a given moment; the electricity generated over a year depends on sunshine, wind and operating conditions.

The solar and wind exports together could generate about 720 terawatt hours annually in their destination countries. Solar exports alone account for an estimated 6.4 billion tonnes of avoided emissions over their lifetimes, making them the largest contributor by a wide margin.

Developing countries accounted for about 73% of lifetime emissions savings from Chinese clean technology exports in 2025. Their share rose to 76% in the first three quarters of 2026, with South and Southeast Asia together accounting for 52% of the total.

Sunny conditions help explain those shares. So do electricity systems that rely heavily on fossil fuels: replacing a unit of coal power generally saves more carbon dioxide than replacing electricity from a cleaner grid.

Pakistan illustrates the appeal. An earlier annual estimate put its imports of Chinese solar panels at up to 17 gigawatts, approximately matching Germany's solar additions during the same period. For households and businesses facing frequent electricity shortages, affordable panels offer a way to generate their own power. Nearly two thirds of Chinese solar panel and photovoltaic cell exports went to developing countries in that earlier period.

From Ethiopian cars to electricity for Vietnam

Ethiopia banned imports of vehicles with internal combustion engines in 2024, seeking to reduce the foreign currency spent on imported fossil fuels. Affordable Chinese electric vehicles helped make that decision possible. Larsen described them as the cheapest and most effective option for Ethiopia's needs.

China's vehicle exports extend far beyond passenger cars. In 2025, shipments included 36 million electric vehicles with two wheels, 2.2 million battery electric cars, 160,000 plug-in hybrid cars, 15,000 buses and 30,000 trucks. Exported batteries had a combined capacity of 305 gigawatt hours, enough for roughly 5 million additional electric cars using typical battery sizes.

Laos offers a different model. The Monsoon Wind project began operating in August 2025, using 133 Chinese-built turbines to supply electricity to Vietnam's manufacturing sector. A consortium led by Thai investors owns the project, showing how Chinese equipment can support projects organised by companies from other countries.

China-linked renewable projects overseas included 69 gigawatts operating, 100 gigawatts under construction and 280 gigawatts planned as of July 2026. Even so, equipment exports account for a much larger climate benefit than Chinese ownership of overseas energy projects. Local developers and other companies carry out most project development.

Several milestones show how quickly this trade has become part of national energy strategies:

• 2024: Ethiopia banned imports of vehicles with internal combustion engines.
• August 2025: The Monsoon Wind project in Laos began supplying electricity to Vietnam.
• March 2026: China adopted a five year plan pledging a larger role in global climate governance.
• November 9–20, 2026: COP31 brings climate finance, technology access and trade tensions into negotiations in Antalya.

Trade rules still make technology harder to obtain

The United Nations Conference on Trade and Development, known as UNCTAD, identifies a gap between climate promises and practical trade policy in its November 2026 report, Accelerating Climate Action Requires Trade Cooperation.

UNCTAD examined 179 climate provisions in eight regional trade agreements signed between 2023 and 2025. Only 7% addressed tariffs or other barriers to climate technologies. General statements of climate intent accounted for 22%, while 18% called for cooperation. Most commitments lacked legally enforceable obligations.

Tariffs are taxes on imports. Other barriers include different product standards, certification procedures and testing requirements. Smaller businesses in developing countries can struggle to pay for those checks or find accredited laboratories and verifiers.

A United Nations survey of 174 countries in 2025 found only seven reporting full implementation of measures for green and climate smart goods. Twelve reported partial implementation, 14 were planning measures and 57 had implemented none.

The market affected is enormous. Global exports across solar and wind value chains exceeded $1.8 trillion in 2025, covering everything from production inputs to finished equipment. Battery trade grew 29% and electric car trade 11% in the first half of 2026.

Washington has imposed tariffs exceeding 100% on Chinese electric vehicles to protect domestic manufacturers. European measures also reflect concerns about competition and industrial jobs. For countries seeking cheaper technology, those trade disputes can affect both prices and access. UNCTAD calls for cooperation on standards, certification, technical assistance and investment to reduce such costs.

The competition is moving into factories and fuels

China's advantage now reaches beyond solar panels and vehicles into industries that are harder to clean up. Mission Possible Partnership, a nonprofit organisation working on industrial emissions, found that China secured 23 of 36 major clean industrial projects financed during the preceding year. Those Chinese projects were worth more than €40 billion.

China hosts 49% of clean industrial plants operating or under construction worldwide. It also accounts for more than 90% of capacity for lower emissions methanol and more than 40% of cleaner aluminium capacity. Methanol can be produced using biomass or renewable hydrogen, while cleaner aluminium relies on electricity with lower carbon emissions.

Other emerging economies are attracting projects of their own. Six secured €4.7 billion in financing during the same period, compared with €4.3 billion in developed economies. Another 281 projects were in development across emerging markets.

Kenya is developing a fertiliser plant powered by geothermal energy, targeting annual output of 200,000 to 300,000 tonnes, mostly for domestic farmers. Paraguay has secured financing for cleaner fertiliser production. South Africa has attracted investment in aviation fuel made from captured carbon dioxide and renewable electricity.

The European Union launched its Clean Industrial Deal in February 2025, pledging to mobilise more than €100 billion. Its requirement for aviation fuel suppliers to provide at least 2% sustainable aviation fuel from 2025 has also helped create demand. Financing remains difficult worldwide: Mission Possible Partnership tracks more than 800 proposed projects, representing about €4.3 trillion, that have yet to secure funding.

China's coal expansion complicates its climate role

China accounts for roughly one third of global carbon dioxide emissions, with coal supplying more than half its electricity. Its emissions have followed a broadly flat or falling trend since March 2024, but recent movements show the pressure from continuing energy demand.

Emissions rose 2% in the first quarter of 2026 and fell 1% in the second, leaving the first half marginally higher than a year earlier while still below the March 2024 peak. Lower oil use helped drive the second quarter decline as electric vehicles reduced demand for transport fuel. Coal use in power generation rose.

China added 30 gigawatts of coal power capacity in the first half of 2026. Another 290 gigawatts were under construction at the end of 2025. Those investments put new generating assets into an electricity system that must also absorb growing renewable output.

Beijing's 2035 pledge calls for net greenhouse gas emissions to fall 7% to 10% below their peak, nonfossil sources to provide more than 30% of energy consumption, and wind and solar capacity to reach six times its 2020 level. Its broader commitments remain to peak emissions before 2030 and reach net zero before 2060.

Will manufacturing strength become diplomatic leadership?

China's March 2026 plan pledged to take a more active leadership role in global climate governance. COP31 offers an early test of how that language translates into negotiations. Turkey holds the conference presidency, while Australia leads negotiations under an arrangement agreed at COP30.

Former United States secretary of state John Kerry argues that other countries need to match China's pace in clean energy. He described the contrast in direct terms:

"The only country that has hugely accelerated is China. The rest of the world is stumbling along while Mother Nature is sending us more powerful signals every week, every day," he said.

Beijing has historically been cautious about setting the international climate agenda. Agreements with Washington helped prepare the ground for the 2015 Paris Agreement, but the United States' retreat from international climate commitments under President Donald Trump in 2025 changed that relationship.

China must also navigate competing interests among developing countries, including energy exporters, manufacturers and nations vulnerable to climate damage. Its commercial influence gives it a strong voice, while a larger diplomatic role brings expectations of financial support and faster reductions in fossil fuel use.

Negotiators are watching China's climate finance commitments, its support for workers and communities moving away from fossil fuels, and whether it seeks to host COP33 in 2028. A hosting bid has not been announced. The immediate deadline is November 20, when COP31 is scheduled to conclude.
