Working with 4Air, Flexjet in Europe offsets 300 per cent of the carbon dioxide equivalent for every flight, to reflect both CO₂ emissions and other pollutants. Flexjet LLC has also been working hard to neutralise.

Under the opt-in programme, 4AIR will verify the flight activity of participating Jet Linx customers, calculate the emissions from their flights based on fuel use and then purchase credits to fund real-world projects.
