Carbon dioxide emissions rise globally and in U.S., but drop in China
China’s carbon pollution was down 0.9% this year compared to 2021, while emissions in the United States were 1.5% higher, said a study by scientists atreleased early Friday at international climate talks in Egypt. Both are opposite long-term trends. American emissions had been steadily dropping while Chinese emissions had been rising — until this year.
Much of the jump was in transportation — cars and air travel — with Americans' limits on travel during the pandemic wearing off, Friedlingstein said. Friedlingstein’s team — along with other scientific reports — figure Earth can only put 380 billion metric tons of carbon dioxide into the air before Earth reaches the 1.5-degree mark. That’s about 9 to 10 years worth of emissions, meaning the globe will likely hit that point around 2031 or 2032.“This is bad news,” said Brown University climate scientist Kim Cobb, who wasn’t part of the research team.
Pollution from coal jumped 1% from last year, for oil it went up 2% and for natural gas it went down 0.2%, the report said. About 40% of the carbon dioxide comes from burning coal, 33% from oil and 22% from natural gas, Friedlingstein said.
