Overview

  • Study land use & climate mitigation relationship by combining Vulcan 1-km gridded fossil fuel CO2 (FFCO2) & EPA Smart Location Database land use features
  • Partition emissions into transportation, residential energy, & scope 2 residential electricity

Motivation

Newman & Kenworthy (1989)

Literature

  • Urban economics: Glaeser & Kahn (2008) used an ad-hoc CO2 estimation strategy to compare 66 metropolitan areas​
    • Lowest CO2 rates in California​
    • Highest CO2 rates in Texas & Oklahoma​
    • Development restrictions push new development into high CO2 regions​
  • Urban planning: Kockelman (1997) + Cervero & Ewing (2010) examine 3/5Ds of land use​
    • Density, Diversity, Design, Destination Access, & Distance to Transit​
  • Urban science: Fragkias et al. (2013) used earlier version of Vulcan CO2 dataset (1999-2008) to study urban scaling in total CO2​
    • Found proportional scaling of 0.95% increased CO2 per 1% increase in population – i.e., larger cities not significantly more efficient

In their words

This is where a pull-quote goes — styled with a left accent rule instead of a decorative bar, matching the “avoid accent stripes” guidance while still standing apart from body text.
