China mulls bid to host 2028 U.N. climate summit as geopolitical positioning

Beijing is weighing whether to bid for the right to host the United Nations climate summit in 2028, according to two people with knowledge of the deliberations. No final decision has been made, and there is no announced timeline for when one might come. The move would position China as a global climate leader at a moment when the world's environmental politics are in flux.

The summit in question is COP33, the thirty-third annual gathering of the U.N. Framework Convention on Climate Change. The U.N.'s climate conferences rotate among regional blocs, and 2028 falls to the Asia-Pacific region. This year's summit, COP31, is scheduled for Turkey. Ethiopia will host COP32 in 2027. India had previously offered to host COP33 but withdrew that offer in April without explanation. South Korea has also expressed interest in the role.

China's consideration of a bid carries obvious symbolic weight. The country has spent recent years positioning itself as a counterweight to the United States on the world stage, particularly on climate matters. The Trump administration has withdrawn from the Paris climate agreement and is actively promoting fossil fuel development. For Beijing, hosting the 2028 climate talks would be a high-profile opportunity to assert itself as a serious climate actor and to contrast its stance with American policy.

There is also a straightforward economic calculation at play. China is the world's leading exporter of green technologies—solar panels, electric vehicles, wind turbines, batteries. Hosting the summit would elevate the profile of these industries and reinforce China's position in the global clean energy market. The country's manufacturing prowess and technological reach give it genuine leverage in these sectors.

Yet the bid carries a significant complication. China is the world's largest emitter of greenhouse gases, a consequence of its massive population of 1.4 billion and its enormous manufacturing base. While the country has committed to achieving carbon neutrality by 2060, its interim targets are modest. It is aiming for only a 7 to 10 percent reduction in economy-wide greenhouse gas emissions by 2035, measured against peak levels. Hosting a global climate summit while pursuing such limited near-term emissions cuts would inevitably invite scrutiny and questions about the sincerity of its climate commitments.

Another layer of calculation involves the United States. Climate cooperation was a cornerstone of the bilateral relationship under Presidents Barack Obama and Joe Biden. If a Democrat wins the 2028 presidential election, the summit—which would likely occur days after that election—could serve as a platform for renewed collaboration between the two countries. One source suggested this U.S.-China dynamic is part of what Beijing is considering. Alden Meyer, a climate analyst at the think tank E3G, noted that the relationship between the two powers has been both a driver of progress and a source of tension throughout the thirty-five-year history of international climate negotiations, and that dynamic will remain complicated regardless of who occupies the White House.

The U.N. Framework Convention on Climate Change secretariat has not yet been formally notified of any nomination from the Asia-Pacific regional group. The process requires regional groups to consult among themselves first, agree on a candidate country, and then formally submit that nomination to the secretariat. China's interest, first reported by Bloomberg News, remains in the exploratory phase. The Chinese Embassy in Washington did not respond to requests for comment.
