25 megabyer producerer 52% af Verdens ‘klimagasser’ og 23 af dem er kinesiske

Just 25 ‘mega-cities’ produce 52 per cent of the world’s urban greenhouse gas emissions — and 23 of them are in China

  • Researchers from Sun Yat-sen University recorded the emissions of 167 cities
  • The largest carbon emitters were found to be Asian megacities like Shanghai
  • Cities in Europe and the US emit more than those in most developing countries
  • Of 42 cities with data spanning 2012–2016, 30 showed emissions reductions
  • Yet the team warned we are not on track to meet global climate change targets

At present, China is running a whopping 1,058 coal-fired power plants — equal to more than half of the world’s entire capacity. 

In their study, Dr Chen and colleagues looked at greenhouse gas emissions from 167 cities across 53 countries.

The worst 75 cities for total emissions were as follows (with figures in megatonnes of CO₂ equivalent):
