Treat the footprint as a map of leverage, not a moral score

A useful personal footprint model separates the big buckets: travel, driving, home energy, and food. The EPA calculator and EPA equivalencies tool are good official references for interpreting the scale of emissions.

"The best next action is usually in the largest category, not the category that feels most visible."

Boundary

This is a personal annual footprint estimate, not a verified corporate inventory.

Energy mix

Local electricity factors can move the result materially, so treat the power mix selector as a scenario lever.

Reduction first

Offsets are shown separately because direct reductions and purchased offsets are different decisions.

Frequently Asked Questions

  • It combines annual flights, car miles, public transit, home electricity, heating fuel, diet assumptions, household size, and offsets into an annual CO2e estimate. For official context, compare the result with the EPA Household Carbon Footprint Calculator and the EPA GHG Equivalencies Calculator.
  • Electricity emissions depend on the local power mix. This calculator uses broad planning factors, while official inventories use location-specific factors and activity data.
  • Offsets can be useful, but reduction first is the safer planning sequence: reduce travel, energy, and consumption where possible, then use verified offsets for emissions that remain.
  • No. It is a personal planning estimate. Formal reporting normally requires a defined boundary, official emission factors, documentation, and sometimes verification.
