How to Use
1. Enter your weekly driving distance and car type 2. Count your flights per year (short = domestic, long = international) 3. Select your diet — food is responsible for 20–30% of most people's footprint 4. Enter your monthly electricity usage from your billWhat's not included: Manufacturing of goods, public transport, natural gas, waste. This covers the 4 biggest categories for most Australians.
Formula
Total CO₂e = Car emissions + Flight emissions + Diet emissions + Electricity emissionsFrequently Asked Questions
What is the average Australian carbon footprint?
Australians average 15.4 tonnes of CO₂e per person per year — one of the highest in the world. The global average is 4.7 tonnes. The Paris Agreement target requires getting to ~2 tonnes per person by 2050.
What is the biggest contributor to my footprint?
For most Australians: flights (if you fly internationally), then diet (especially red meat), then car transport, then home energy. A single Sydney–London return flight produces ~3.5 tonnes CO₂e.
How can I offset my carbon footprint?
Carbon offsets fund projects that reduce emissions elsewhere (reforestation, clean energy). Look for Gold Standard or VCS certified offsets at ~$20–30/tonne. Offset is a last resort — reducing first is always better.
