China's Clean-Tech Exports Could Avert 450 Million Tonnes of CO₂ a Year
An analysis by the Centre for Research on Energy and Clean Air (CREA) estimates that China's 2026 exports of solar, wind, battery and electric vehicle technology could prevent about 450 million tonnes of CO₂ a year abroad. That is comparable to Brazil's annual fossil fuel emissions.
Solar panels, wind turbines, batteries and electric vehicles exported by China could prevent around 450 million tonnes of carbon dioxide (CO₂) emissions a year outside the country. That is roughly what Brazil emits annually from burning fossil fuels. The estimate comes from an analysis by the Centre for Research on Energy and Clean Air (CREA), published by Carbon Brief, and it suggests that Chinese-made technology can shape emissions in other countries.
What the calculation covers
The analysis concerns technologies China exports in 2026 and their expected impact once installed or put into use. The full-year projection assumes that the export growth seen in the first nine months will continue through the final quarter.
In the first three quarters of the year, exports of electric cars and heavy vehicles rose by 61%, wind turbines by 45%, batteries by 39% and solar equipment by 22%.
Solar power and manufacturing emissions
According to Reuters, solar technology delivers the largest emissions savings. Its impact is especially significant in countries whose electricity supply still relies heavily on fossil fuels, where solar panels replace power that is produced with high emissions.
The researchers also accounted for emissions generated while manufacturing the equipment in China. According to the analysis, the production emissions of the exported technology could be offset on average after about six months of operation.
Over their full lifetimes, the technologies exported this year could prevent 8.4 billion tonnes of CO₂, comparable to the combined annual emissions of the United States and India. This figure covers many years of use, not a single year.
Limitations
These are modelled benefits. The Associated Press (AP) reports that independent experts found the estimate consistent with the scale of China's exports but could not verify the underlying data. The actual outcome will also depend on where and how the technologies are used.
AP stresses that China at the same time holds a dual role: it is the world's largest source of CO₂ emissions and the largest supplier of clean energy technology.
