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.
