Summary

Using zip code level data on many dimensions, research questions:

  1. "how much variability exists in the size and composition of household carbon footprints across all U.S. locations"
  2. "how much of this variability can be explained by population density, income, home size, and other factors contributing to carbon footprints in urban, suburban, and rural areas?"

Found lots of variation across US, especially dependent on electricity source.

Income is largest contributing factor. Density inverse U-shaped: increasing emissions up to 3k/square mile, then decreasing. Excepting NY and LA, larger metros have higher household emissions due to suburbs having especially high emissions. Exception might point to inverse U-shape for overall metro size.

Calls for nuanced policy interventions given regional variation and relationship of central cities and suburbs.
