50% of population: https://ourworldindata.org/urbanization#how-urban-is-the-wor...

70% of emissions: https://www.c40.org/why_cities

This is based on the concept of a "consumption emission", which is an interesting concept. The point being that cities (especially western cities) have seen their emissions drop due to de-industrialization, but consumption has increased (hence your statement about carbon footprints correlating to wealth/income). To say that cities impacts are smaller when they just outsource all of their carbon impact is disingenuous.

From your source: It usually incorporates the population in a city or town plus that in the suburban areas lying outside of, but being adjacent to, the city boundaries.

GGP suggested that suburban living is greener. How does the 50%/70% support his point if cities include the suburbs?
