What is the average carbon footprint per person?

The global average is about 4 tonnes of CO₂ per year. The US average is about 14 tonnes; the EU average is about 6-8 tonnes. The 1.5°C climate target requires getting to about 2.3 tonnes per person by 2030.

What is the biggest contributor to personal carbon footprint?

For most people in developed countries, transport (especially flying and car use) and home energy are the largest contributors, together accounting for 50-70% of personal emissions.
