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. Just over half of the world's urban greenhouse gas emissions come from just 25 mega-cities, with Shanghai (pictured, Tokyo and Moscow topping the list, a study has foundTHE WORST EMITTERS In their study, Dr Chen and colleagues looked at greenhouse gas emissions from 167 cities across 53 countries. The two main sources of greenhouse gas emissions, the team found, came from so-called stationary energy the transportation sector. Current urban greenhouse gas mitigation efforts are not enough to meet global targets to limit the extent of climate change by the century's end, the researchers warned. Next, he added, urban greenhouse gas reductions policies need to be monitored with methodologically consistent emissions inventories.
