How This Works

Carbon footprint = sum of CO₂-equivalent emissions from electricity (UK grid factor 0.2kg/kWh), heating fuel type, car miles (UK average petrol 210g CO₂/mile), flights (0.6t CO₂e per short-haul return trip inc. radiative forcing) and diet (Oxford University Poore & Nemecek 2018 figures).

Switching from a meat-heavy diet to vegan saves ~2.2t CO₂e/year. Dropping one long-haul flight saves 1.5–3t. Switching to a heat pump saves 1–2t. These three changes alone could halve a typical UK carbon footprint.
