Just over half of the world’s urban greenhouse gas emissions come from just 25 mega-cities — 23 of which are located in China — a study has reported.
The cities that emit the most greenhouse gases included Handan, Suzhou, Dalian, Beijing and Tianjin in China — but also Tokyo, Japan, and Moscow, Russia.
China’s President Xi Jinping has pledged to cap carbon emissions by 2030 and achieve carbon neutrality by 2060 — part of its commitment to the Paris Agreement.
