Carbon Footprint Calculator

What is the Carbon Footprint Calculator – CO₂ Emissions?

The carbon footprint calculator estimates the carbon dioxide emissions of a household or journey from transportation, housing, and consumption. The average carbon footprint is about 8–9 tCO₂/year, with a target of less than 2.5 t.

The calculator is free, works directly in the browser, and does not require registration. All figures are based on standard data.

Calculation Principle

CO₂ (kg) = Activity × Emission Factor (kg CO₂/unit)

Fill in the fields of the calculator with your information and press the calculate button – the result will be displayed immediately. Try different values to compare options.

Practical Example

Car 15,000 km/year, gasoline 7 l/100 km → 1,050 l × 2.31 kg CO₂/l = 2,426 kg CO₂. Flight round trip ≈ 350 kg CO₂.

Enter your own numbers into the calculator to get a personal result. The calculator is designed for quick use in everyday situations.

When do you need this calculator?

The calculator is needed to support decision-making, budgeting, and cost comparisons. Getting accurate references quickly makes everyday life easier.

The result is an estimate – for important financial or construction decisions, we recommend consulting a professional.

Tips

• Smallest action: fly less – one transatlantic flight = several years of emissions from the rest of life.
• A plant-based diet reduces the carbon footprint of food by 30–50%.
• Switching the heating method to a heat pump is a significant step in reducing home emissions.
