The world's most polluting cities are revealed at COP29 as frustration grows at fossil fuel presence

BAKU, Azerbaijan (AP) 鈥 Cities in Asia and the United States emit the most heat-trapping gas that feeds climate change, with Shanghai the most polluting, according to new data that combines observations and artificial intelligence.

are trying to set new targets to cut such emissions and figure out to help the world with that task. The data comes as climate officials and activists alike are growing increasingly frustrated with what they see as the talks' 鈥 and the world's 鈥 inability to clamp down on planet-warming fossil fuels and the countries and companies that promote them.

Seven states or provinces spew more than 1 billion metric tons of greenhouse gases, all of them in China, except Texas, which ranks sixth, according to new data from an organization co-founded by former U.S. Vice President Al Gore and released Friday at COP29.

Using satellite and ground observations, supplemented by artificial intelligence to fill in gaps, Climate Trace sought to quantify heat-trapping carbon dioxide, methane and nitrous oxide, as well as other traditional air pollutants worldwide, including for the first time in more than 9,000 urban areas.

Earth's total carbon dioxide and methane pollution grew 0.7% to 61.2 billion metric tons with the short-lived but extra potent methane rising 0.2%. The figures are higher than other datasets 鈥渂ecause we have such comprehensive coverage and we have observed more emissions in more sectors than are typically available,鈥 said Gavin McCormick, Climate Trace's co-founder.

Plenty of big cities emit far more than some nations

Shanghai's 256 million metric tons of greenhouse gases led all cities and exceeded those from the nations of Colombia or Norway. Tokyo's 250 million metric tons would rank in the top 40 of nations if it were a country, while New York City's 160 million metric tons and Houston's 150 million metric tons would be in the top 50 of countrywide emissions. Seoul, South Korea, ranks fifth among cities at 142 million metric tons.

鈥淥ne of the sites in the Permian Basin in Texas is by far the No. 1 worst polluting site in the entire world,鈥 Gore said. 鈥淎nd maybe I shouldn鈥檛 have been surprised by that, but I think of how dirty some of these sites are in Russia and China and so forth. But Permian Basin is putting them all in the shade.鈥

China, India, Iran, Indonesia and Russia had the biggest increases in emissions from 2022 to 2023, while Venezuela, Japan, Germany, the United Kingdom and had the biggest decreases in pollution.

The dataset 鈥 maintained by scientists and analysts from various groups 鈥 also looked at traditional pollutants such as carbon monoxide, volatile organic compounds, ammonia, sulfur dioxide and other chemicals associated with dirty air. Burning fossil fuels releases both types of pollution, Gore said.

This 鈥渞epresents the single biggest health threat facing humanity,鈥 Gore said.

Climate talks wrestle with fossil fuel interests

Gore criticized the hosting of climate talks, called COPs, by Azerbaijan, an oil nation and site of the world's first oil wells, and by the United Arab Emirates last year.

鈥淚t鈥檚 unfortunate that the fossil fuel industry and the petrostates have seized control of the COP process to an unhealthy degree,鈥 Gore said. 鈥淣ext year in Brazil, we鈥檒l see a change in that pattern. But, you know, it鈥檚 not good for the world community to give the No. 1 polluting industry in the world that much control over the whole process.鈥

Brazil President Luiz In谩cio Lula da Silva has called for more to be done on climate change and has sought to slow deforestation since returning for a third term as president. But Brazil last year produced more oil than both Azerbaijan and the United Arab Emirates, according to the

On Friday, former U.N. secretary-general Ban Ki-moon, former U.N. climate chief Christina Figueres and leading climate scientists released a letter calling for 鈥渁n urgent overhaul鈥 on climate talks.

The letter said the 鈥済lobal climate process has been captured and is no longer fit for purpose鈥 in response to Azerbaijan's president Ilham Aliyev saying that oil and gas are a 鈥済ift of the gods.鈥

U.N. Environment Programme Executive Director Inger Andresen said she understands much of the frustration in the letter calling for massive reform of the negotiation process, but said their push to slash emissions fits nicely with U.N. Secretary-General Antonio Guterres鈥 .

One key benefit of the U.N. climate talks process is it is the only place where victim small island nations have an equal seat at the table, Andersen told The Associated Press. But the process has its limits because 鈥渢he rules of the game are set by member states,鈥 she said.

An analysis from the Kick Big Polluters Out coalition said Friday that the official attendance list of the talks featured at least 1,770 fossil fuel lobbyists.

At a press conference with small island nations chair Cedric Schuster said the negotiating bloc feels the need to remind everyone else why the talks matter.

鈥淲e鈥檙e here to defend the Paris agreement,鈥 Schuster said, referring to the climate deal in 2015 to limit warming to 1.5 degrees Celsius (2.7 Fahrenheit). 鈥淲e鈥檙e concerned that countries are forgetting that protecting the world鈥檚 most vulnerable is at the core of this framework.鈥 ___
