25 Cities Account For The Majority Of Global Urban Greenhouse Gas Emissions

The Hill: Study: Just 25 cities account for majority of global urban greenhouse gas emissions 

Just 25 cities comprise more than half of greenhouse gas emissions from a sample of 167 urban centers, according to research published Monday in the journal Frontiers in Sustainable Cities. 

Researchers analyzed a sample of 167 cities and metropolitan areas in 53 countries, including more cities from countries that are major emitters, such as China, the U.S. and India. They then compared the cities’ respective levels of progress in carbon reduction based on 2012 and 2016 emissions inventories, in combination with their short and long-term reduction targets. 

The researchers found that 25 cities accounted for 52 percent of the sample’s emissions. All but three of the 25 — Moscow, Istanbul and Tokyo — were located in China, including major cities such as Shanghai and Beijing.
