Willie Walsh, Chief Executive Officer of British Airways, addressed the Aviation and Environment Summit about best operational practice for airlines. Walsh recognised that the economy had replaced the environment as the key public concern in recent months, although he highlighted that this change did not translate into changing priorities for airlines. The environment remains a key priority for British Airways (BA) and other airlines, with the economy and environment presenting a win – win situation. Investment in fuel efficient measures (including new airplanes, route shortening, reducing the weight of aircraft, to name but a few) reduces the amount of fuel consumed, decreasing both cost and carbon dioxide emissions. Walsh added that BA aims to cut CO2 emissions by 50% by 2050 and is absolutely committed to IATA’s four-pillar strategy on climate change.
