More China-invested overseas coal-fired power capacity was cancelled than commissioned since 2017, research showed on Wednesday, highlighting the obstacles facing the industry as countries work to reduce carbon emissions.
The Centre for Research on Energy and Clean Air (CREA) said that the amount of capacity shelved or cancelled since 2017 was 4.5 times higher than the amount that went into construction over the period.
Coal-fired power is one of the biggest sources of climate-warming carbon dioxide emissions, and the wave of cancellations also reflects rising concerns about the sector's long-term economic competitiveness.
Since 2016, the top 10 banks involved in global coal financing were all Chinese, and around 12% of all coal plants operating outside of China can be linked to Chinese banks, utilities, equipment manufacturers and construction firms, CREA said.
But although 80 gigawatts of China-backed capacity is still in the pipeline, many of the projects could face further setbacks as public opposition rises and financing becomes more difficult, it added.
China is currently drawing up policies that it says will allow it to bring greenhouse gas emissions to a peak by 2030 and to become carbon-neutral by 2060.
But it was responsible for more than half the world's coal-fired power generation last year, and it will not start to cut coal consumption until 2026, President Xi Jinping said in April.
Environmental groups have called on China to stop financing coal-fired power entirely and to use the funds to invest in cleaner forms of energy, and there are already signs that it is cutting back on coal investments both at home and abroad.
Following rule changes implemented by the central bank earlier this year, "clean coal" is no longer eligible for green financing.
Industrial and Commercial Bank of China, the world's biggest bank by assets and a major source of global coal financing, is also drawing up a "road map" to pull out of the sector, its chief economist Zhou Yueqiu said at the end of May.
