Cities with affluent residents who lead high-consumption lifestyles are driving global atmospheric pollution.

MIT Tech Review, May 2021

Cities with affluent residents – and corresponding high consumption lifestyles, account for the largest carbon footprints. (LA, New York and Shenzhen produce the biggest carbon footprint per capita).

Old megacities will lead on climate change

But slowing growth and greater resources should mean these ‘old’ megacities will be better able to adapt for climate change. Shenzhen is shifting to low emission public transport, promotes green buildings and expects to hit peak carbon emissions in 2022.

Rising megacities will suffer

The rising megacities will mainly be in Africa and Asia. By 2035 Kinshasa will support a population of 26.7 million – much larger than Shenzhen’s predicted 15.2m.

However despite its lower carbon footprint, with fewer resources and less opportunity to build resiliency, residents there will face many climate change hazards including food insecurity, drought, natural disasters, and extreme temperatures.

Best and worst of times

The wealth and technology concentrated in metro areas could lead the way in addressing climate change – if the lessons are applied equally well across all cities.
