Space-based quantification of per capita CO2 emissions from cities

Urban areas are currently responsible for ~70% of the global energy-related carbon dioxide (CO2) emissions, and rapid ongoing global urbanization is increasing the number and size of cities. Thus, understanding city-scale CO2 emissions and how they vary between cities with different urban densities is a critical task. While the relationship …
