Answer 15 quick questions about your lifestyle to estimate your annual CO2 emissions. Takes about 2 minutes.
FAQ
A carbon footprint is the total amount of greenhouse gases (measured in CO2 equivalent) produced by your activities. It includes transportation, home energy, diet, and consumption.
The global average is about 4 tonnes CO2 per year. Americans average about 16 tonnes, Europeans 6-8 tonnes. Climate targets suggest we need to reach 2 tonnes per person by 2050.
The biggest impacts come from reducing car and air travel, switching to renewable energy, eating less red meat, and reducing consumption. Small changes across multiple areas add up significantly.
About this test
The carbon footprint calculator estimates your annual CO2 emissions across four categories: transportation, home energy, diet, and consumption. Compare your footprint to regional and global averages.
How It Works
Answer questions about your transport habits, home energy use, diet choices, and shopping patterns. The calculator estimates your annual carbon emissions in tonnes of CO2 equivalent.
Why It Matters
Understanding your personal emissions helps identify the most impactful changes you can make. Individual action, combined with systemic change, is necessary to address climate change.
Reduction Tips
- Transportation is usually the largest category — drive less, fly less
- Switch to renewable energy if available in your area
- Reduce red meat consumption — it has the highest food emissions
- Buy less, buy used, and choose durable products
