The pledge comes as part of a new partnership with Durrell Wildlife Conservation Trust.
From Monday (22 November) all Blue Islands seats booked to fly from 1 December will include a £1 carbon offset contribution.
The carrier is also seeking to reduce its environmental impact through a series of "next-generation technologies" and aiming for a longer-term zero-carbon target.
Durrell’s Rewild Carbon programme aims to “revive eco-systems, recover species, reduce carbon and rebuild livelihoods”, with 95% of all funds received going towards its nature projects.
