Trip Carbon Footprint Calculator

Total the carbon footprint of a whole trip across all components.

About Trip Carbon Footprint Calculator

Flights typically dominate trip emissions to the point where every other component is a rounding error. Comparing the total with an annual carbon budget puts the scale in perspective. A single long-haul return trip can consume most of a year’s sustainable carbon budget, which no amount of accommodation choice offsets.

Formula

Trip Carbon Footprint

Total = flights + ground transport + accommodation + food and activities

two-tonne budget
The per-person annual figure often cited as consistent with 1.5 degrees

Assumptions and limits

  • The result is derived only from the 5 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is Trip Carbon Footprint calculated?

Total = flights + ground transport + accommodation + food and activities Flights typically dominate trip emissions to the point where every other component is a rounding error. Comparing the total with an annual carbon budget puts the scale in perspective.

Why does Trip Carbon Footprint matter?

A single long-haul return trip can consume most of a year’s sustainable carbon budget, which no amount of accommodation choice offsets.

What values do I need to enter?

This calculator takes 5 inputs: Flight emissions, Ground transport emissions, Accommodation emissions, Food and activities emissions, Offset price per tonne. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
