Key Findings

 

One observation that can be made based on this model is in many countries, a small number of large and or affluent cities drive a significant share of national total emissions.

 

This means concerted action by a small number of local mayors and governments has the potential to significantly reduce national total carbon footprints. Some other observations based on the results include:

 

● Globally, carbon footprints are highly concentrated into a small number of dense, high-income cities and affluent suburbs

 

● 100 cities drive 18% of global emissions

 

● In most countries (98 of 187 assessed), the top three urban areas drive more than one-quarter of national emissions

 

● We define cities as population clusters, but in practice mapping footprints to local jurisdictional bounds is complex

 

● 41 of the top 200 cities are in countries where total and per capita emissions are low e.g. Dhaka, Cairo, Lima). In these cities population and affluence combine to drive footprints at a similar scale as the highest income cities

 

● For large and high-income cities, their total Scope 3 footprint is much larger than the city's direct emissions

 

● Radical decarbonization measures (limiting nonelectric vehicles; requiring 100% renewable electricity) can induce substantial emissions reductions beyond city boundaries. In wealthy, high-consumption, high-footprint localities such measures may require only a small investment relative to median income, yet accomplish large reductions in total footprint emissions

 

● Local action at the city and state level can meaningfully affect national and global emissions
