China releases more greenhouse gases into the atmosphere than all developed countries combined, and in 2019 it accounted for 27 percent. global emissions of these gases - according to a report by the Rhodium Group research institution, reported on Friday by the BBC.
The second place in the ranking was taken by the United States, which accounted for 11 percent. global emissions, and in the third India with 6.6 percent.
Scientists warn that dangerous climate change will be difficult to avoid unless the US and China agree to reduce emissions.
China is the most populous country in the world and still releases significantly less greenhouse gases per capita than the US. However, Chinese per capita emissions are also rising and have tripled in the past 20 years, the report said.
The communist authorities in Beijing have announced efforts to achieve carbon neutrality by 2060. According to promises, emissions are expected to start falling by 2030 at the latest.
However, as the BBC points out, China's energy production is still largely based on coal. There are currently 1,058 coal-fired power plants in operation in the country, accounting for more than half of the global electricity production from coal.
PRC leader Xi Jinping said in April at a virtual climate summit hosted by US President Joe Biden that over the next five years China would "tightly control coal-fired power plant projects" and "rigorously limit the growth of coal consumption."
Earlier in April, China was visited by Biden's special envoy on climate, John Kerry, who, despite political and diplomatic tensions between the two countries, discussed there with his Chinese counterpart Xie Zhenhu about coordinating efforts to combat climate change.
