This calculator estimates your annual carbon footprint across four main areas: your diet, home energy use, flights, and ground transport. Fill in each section and you get a total in tonnes of CO2-equivalent per year, along with a comparison to the global average. The breakdown shows which parts of your lifestyle have the biggest impact.
Most people are surprised by how much long-haul flights contribute relative to everyday habits. A single return flight to a distant destination can add more emissions than months of driving. Diet is the other major surprise area, with beef-heavy diets contributing significantly more than plant-based ones. Seeing numbers broken down by category is usually more useful than just a total.
Frequently Asked Questions
What is the average global carbon footprint?
The global average is around 4 tonnes of CO2-equivalent per person per year. The US and Australia average much higher at 14-16 tonnes, while many African and South Asian countries sit below 1 tonne.
How accurate is this calculator?
It gives a reasonable estimate based on standard emission factors. Treat the result as a directional guide rather than a precise measurement.
What counts as a high carbon footprint?
Anything above 10 tonnes per year is considered high. Sustainable targets are generally cited as 2 to 3 tonnes per person per year by 2050.
What is the highest-impact change I can make?
It depends on your habits. Flying less, switching to a plant-rich diet, and moving to renewable home energy are typically the highest-impact individual actions.
