The urban agglomerations of Cairo, Jakarta, and Tokyo all had populations that exceeded 30 million people, for instance, but these cities had comparatively low carbon footprints (below 150 million tons). As shown by the chart below, emissions generally tracked closely with a city’s population, though there were exceptions. The maps on this page depict the carbon dioxide footprints for cities in Asia and North America-two of the highest emitting regions in the world. Seoul, Guangzhou, New York, Hong Kong, and Los Angeles had the largest carbon footprints in the world, according to the research team. “This means concerted action by a small number of local mayors and governments has the potential to significantly reduce national total carbon footprints.” “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. 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. The key to stopping or slowing global warming may lie with cities-particularly large and wealthy ones.
