"We understand that it is crucial that we strive to do better by the people and places that we collectively depend on."

The Travalyst scheme, an independent non-profit body backed by major tourism industry companies including Google, Booking.com, TripAdvisor, and Expedia, aims to help travellers to cut their carbon emissions, prevent over-tourism and develop local economies.

Harry founded Travalyst before he and his wife - the Duke and Duchess of Sussex - stepped down from their official royal roles in 2020.
