SEOUL, June 10 (Yonhap) -- Seoul has been surveyed to be the world's No. 1 city in terms of carbon emissions, or carbon footprint (CF), but the world's 200th in regards to per capita CF, a Norwegian study said.

According to the survey conducted by a research team from the Norwegian University of Science and Technology, led by Daniel Moran, Seoul made the No. 1 post among 13,000 cities of 187 nations by generating 276.1±51.8 million tons (MT) of carbon, followed by China's Guangzhou (272.0±46.2 MT) and New York (233.5±75.4 MT).

The survey, published in the international science journal Environmental Research Letters on Thursday, is based on the Gridded Global Model of City Footprints that makes use of data on population and purchasing power.

Seoul's ranking was based on a population of 21.25 million that included the population of the metropolitan area as of 2015, the survey said.

Five other local cities were also put on the Top 500 CF list -- Busan (50th, 42.3±15.6), Daegu (115th, 20.4±8.7 MT), Daejeon (126th, 19.2±8.0 MT), Gwangju (132nd, 18.5±7.8 MT) and Ulsan (155th, 15.4±5.6)

However, Seoul was ranked 200th in CF per capita with 13.0±52.4 MT, the survey said. Hong Kong was at the top with 34.6±6.3 MT.

"Studies have shown that CFs are highly concentrated by income, with the top decile of earners driving 30-45 percent of emissions. Concerted action by a limited number of local governments can have a disproportionate impact on global emissions," Moran said.
