The results contained in this report show that policies that aim to reduce emissions by managing demand, through raising the price of air travel, are likely to fail. Tourists are shown to be very sensitive to prices for air travel on competing airlines or to alternative destinations. However, at the national or supra-national level these choices cancel each other out and the overall market is much less sensitive to the cost of air travel. It is economic growth and incomes that are found to have been the key drivers of air travel demand, and those drivers are expected to remain particularly strong in the developing markets of Asia. Decoupling emissions from travel growth needs to focus not on demand management but on mechanisms to bring about emission reduction measures from technology, infrastructure and operations.
