We designed our methods to estimate carbon, nitrogen, and phosphorus fluxes through individual households, and to address two primary questions:

  1. How are these fluxes distributed across households?
  2. What biophysical and socioeconomic factors contribute to differences in these fluxes across households?

Our hybrid approach combines:

  • a mailed survey (pdf)
  • energy provider records
  • on-the-ground landscape measurements
  • a computational tool (the Household Flux Calculator)
  • parcel data (interpreted using GIS)

The resulting dataset includes information on biophysical and socioeconomic variables that potentially influence household-level fluxes of elements. Using this method to study element fluxes at the household level allows us to explicitly link consumption choices and element fluxes.
