Consumption-based emissions in rich cities like New York will have to fall by as much as two thirds to put world on track for 1.5C target
Consumption levels in cities must be cut in half by 2030 to keep 1.5 degree target alive, according to C40 Cities research
City dwellers around the world are making an outsized contribution to climate change, according to new research released today which suggests ‘urban consumption’ levels will have to fall dramatically if the world is to limit global warming to 1.5C.
The analysis, conducted by the C40 Cities group, suggests consumption-based emissions from nearly 100 of the world’s big cities already represent 10 per cent of global greenhouse gas emissions.
Without action to cut emissions associated with what urban businesses and citizens use, eat, and wear – and minimise emissions from the production and transportation of goods and people – city-driven emissions will almost double by 2050, C40 Cities suggests.
To deliver on a 1.5C temperature goal, urban consumption emissions must fall by at least 50 per cent by 2030, the analysis adds.
“This research clearly demonstrates that changing the way we consume could make a significant contribution to cutting emissions,” said Mark Watts, executive director of C40 Cities. “This is a wake-up call for all leaders, business, and citizens to consider both the local and global climate impact of the things they consume, and an opportunity to better engage citizens and businesses in solving the climate emergency.”
The research suggests high income urban areas, such as the richer enclaves of London, Paris,
