Carbon Footprint Calculator

Travel, power, diet, and extras → annual tonnes CO2e and illustrative trees.

Last Updated: 10 Apr 2026

Order-of-magnitude annual footprint: car (gasoline ICE), flights, home electricity with a selectable grid factor, a diet / baseline bucket, and extra lifestyle kg CO2e per month. Trees equivalent uses ~22 kg CO2 absorbed per tree per year (very rough).

Estimated annual: 5.98 tonnes CO2e (5981 kg)

Equivalent trees (rough): 271.9 trees for one year at ~22 kg CO2/tree/yr


  • Car: 2079 kg
  • Flights: 912 kg
  • Electricity: 1890 kg
  • Diet / baseline: 800 kg
  • Lifestyle extras: 300 kg

Carbon Footprint Calculator helps you travel, power, diet, and extras → annual tonnes co2e and illustrative trees. It is commonly used by engineers, lab users, field operators for carbon footprint calculator, co2 emissions travel, electricity carbon calculator.

Inputs (annual where noted)

  • **Driving** (km/year) and gasoline **L/100 km** (ICE approximation)
  • **Flights** (passenger-km/year; illustrative kg per km with radiative forcing multiplier)
  • **Home electricity** (kWh/year) and a **grid intensity** preset (kg CO2e per kWh)
  • **Diet / baseline** lifestyle bucket (kg CO2e per year — user-tuned)
  • **Lifestyle extras** (kg CO2e per month for goods, services, food beyond the baseline)

Outputs

  • Total **kg CO2e** and **tonnes**
  • **Trees equivalent** using an illustrative ~22 kg CO2 absorbed per tree per year (species and climate vary widely)

Factors are order-of-magnitude only—not for carbon accounting compliance.
