What Is a Carbon Footprint?
A carbon footprint measures the total greenhouse‑gas emissions (expressed in tonnes of CO₂ equivalent, or tCO₂e) that result from an individual’s or household’s activities. It is a key metric for understanding how lifestyle choices impact climate change and for setting reduction targets. Try our free to use tool to calculate your carbon footprint today.
How the Calculator Works
- Enter Your Data
- Electricity (kWh / year) – the average yearly electricity consumption of your home or office.
- Car Travel (km / year) – the total kilometres you drive in a typical year.
- Flights (hours / year) – the cumulative flight time you spend annually.
- Meat Consumption (kg / year) – the kilograms of meat you eat each year.
Each field comes with a sensible default (e.g., 4 000 kWh of electricity) so you can start immediately or adjust to your own numbers.
- Click “calculate”
The script applies simplified emission factors: - Electricity: 0.0004 tCO₂e per kWh
- Car: 0.0002 tCO₂e per km
- Flights: 0.5 tCO₂e per hour
- Meat: 0.015 tCO₂e per kg
The total is shown in the read‑only result box (e.g., 2.45 tCO₂e).

- A table lists the exact emissions per category.
Why Use This Tool?
- Personal Insight – Quickly see which habits drive the most emissions.
- Goal‑Setting – Experiment with lower inputs to model the impact of lifestyle changes.
- Educational – Share results with friends, family, or on social media to spark conversations about sustainability.
- Progress Tracking – Recalculate after making changes (e.g., switching to electric vehicles, reducing meat) to monitor improvement over time.
Key Definitions
- tCO₂e (tonnes of CO₂ equivalent) – A unit that aggregates all greenhouse gases into the amount of CO₂ that would have the same global‑warming potential.
- Emission Factor – A coefficient that translates a unit of activity (kWh, km, hours, kg) into the corresponding greenhouse‑gas emissions.
- Sustainability – Meeting present needs without compromising the ability of future generations to meet theirs, often measured through reduced carbon footprints.
Tips for Accurate Use
- Verify Your Data – Use actual utility bills or vehicle odometer readings for precise inputs.
- Include All Travel – Add public transport or cycling if you want a more comprehensive view.
- Adjust Meat Types – The calculator uses a general factor; you can manually lower the value if you mainly consume plant‑based proteins.
