Travel & flight carbon footprint calculator

Use this page as a free **flight carbon footprint calculator** and broader **travel emissions calculator**: add flights, driving, rail, and bus. For each flight you set **cabin class**; we apply country-specific factors and a **radiative forcing** multiplier on aviation so results align with common national guidance.

Add one or more trips, set distance and trips per year, and for flights choose cabin class. We show annual travel CO₂ in kg and tonnes, with a trees equivalent for intuition. Combine with diet and energy tools for a full household picture.
