What is a Carbon Footprint?

A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions. Globally, the average carbon footprint is closer to 4 tons per person. To have the best chance of avoiding a 2℃ rise in global temperatures, the average global carbon footprint per year needs to drop to under 2 tons by 2050.

How This Calculator Works

Our calculator uses standard emission factors to estimate your impact across three primary categories:

Home Energy: We calculate emissions from electricity and natural gas. Electricity factors vary by region, but we use a global average of approximately 0.4kg CO2 per kWh. Natural gas is calculated at roughly 0.2kg per kWh.
Transportation: This is often the largest contributor. We calculate car emissions based on your specific fuel efficiency (2.31kg CO2 per liter of petrol) and flight emissions based on an average of 250kg CO2 per hour of flight time.
Dietary Choices: Food production accounts for significant emissions. A meat-heavy diet can produce double the emissions of a vegan diet due to the methane produced by livestock and the resources required for feed.

Realistic Examples

To put these numbers in perspective, consider these scenarios:

The Urban Commuter: Someone living in an apartment (low energy), taking the train, and eating a vegetarian diet might have a footprint of 3.5 tons.
The Frequent Flyer: A professional who travels internationally for work (50+ flight hours) and drives a large SUV might see a footprint exceeding 15-20 tons.
The Average Household: A family of four in a suburban home typically averages 8-10 tons per person.

How to Reduce Your Carbon Footprint

Lowering your impact doesn't require radical changes overnight. Small, consistent adjustments can lead to significant reductions:

Switch to LED Lighting: Reduces electricity consumption for lighting by up to 80%.
Reduce Meat Consumption: Even "Meatless Mondays" can reduce your food-related emissions by 15%.
Improve Home Insulation: Better insulation reduces the need for heating and cooling, which are the biggest energy drains in most homes.
Choose Direct Flights: Takeoffs and landings use the most fuel; direct flights are more efficient than multi-leg journeys.
