The key to stopping or slowing global warming may lie with cities—particularly large and wealthy ones. That was the major finding of an effort to map the carbon footprint of 13,000 cities—one of the first times researchers analyzed so many areas with a consistent methodology.
“A small number of large and or affluent cities drive a significant share of national total emissions,” said Daniel Moran, an environmental economist at the Norwegian University of Science and Technology. “This means concerted action by a small number of local mayors and governments has the potential to significantly reduce national total carbon footprints.”
Seoul, Guangzhou, New York, Hong Kong, and Los Angeles had the largest carbon footprints in the world, according to the research team.
