Carbon offsetting is only one way of reducing our carbon footprint. We have been making focused efforts to lower our emissions through changes to our operations, technical advances and fleet development. Our aircraft are subject to comprehensive regular maintenance checks to ensure that they are operating at optimal efficiency. Aircraft in our existing fleet have been re-engineered to improve efficiency where feasible, and our fleet development programme means we are now bringing more efficient aircraft into the fleet. We provide technical support to lobbying efforts for more efficient air traffic management that can limit journey times and reduce fuel consumption.
