Researchers calculated the required reduction in ticket price to drive down demand for flights as part of the study.
‘This would translate to a yearly 1.4 per cent increase on ticket prices, breaking the trend of increasing lower airfares,’ said Matt Grote, co-author of the study. ‘The price of domestic tickets has dropped by 1.3 per cent per year between 1979 and 2012, while international fares have fallen by 0.5 per cent per annum between 1990 and 2012,’ he added. Meanwhile, aircraft manufacturer, Boeing, predicts that between 2011 and 2031 aircraft numbers in service will double.
The study also points to deficiencies in the International Civil Aviation Organisation (ICAO), claiming it ‘lacks legal authority to force compliance and therefore is heavily reliant on voluntary cooperation and piecemeal agreements.’
The ICAO has previously set a global average fuel-efficiency improvement target of two per cent per year until 2050, and aims to keep global net CO2 emissions for international aviation stable from 2020. However, global market-based measures to achieve these cuts have yet to be agreed.
