![]() 41 of the top 200 cities are in countries where total and per capita emissions are low e.g.We define cities as population clusters, but in practice mapping footprints to local jurisdictional bounds is complex.In most countries (98 of 187 assessed), the top three urban areas drive more than one-quarter of national emissions.100 cities drive 18% of global emissions.Globally, carbon footprints are highly concentrated into a small number of dense, high-income cities and affluent suburbs.Some other observations based on the results include: This means concerted action by a small number of local mayors and governments has the potential to significantly reduce national total carbon footprints. 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. The dataset is also available on the WRI ResourceWatch platform ( blog). World Economic Forum, NASA's Earth Observatory blog, US News & World Report, National Geographic, among others. This article from Scientific American also gives a nice overview of the study. Is described in the open-access publication It incorporates existing subnational models for the US, China, Japan, EU, and UK. This model provides a globally consistent, spatially resolved (250m), estimate ofĬarbon footprints (also called Scope 3 emissions) in per capita and absolute terms across 189 countries.
