Also high on the agenda at this year’s Farnborough airshow was ‘greener aviation’ and the efforts the aerospace industry is making in pushing forward exciting new developments in sustainable aviation. With aviation growth now set to resume, technologies such as newer ultra-efficient airliners, open-rotor engines and algae-based biofuels will be critical in balancing the worldwide demand for air travel with the need to reduce its carbon footprint. We interviewed two top-level executives - Dr Jean Botti, EADS and Charles Champion, Airbus about some of these ‘green’ developments in aerospace.
