Air Transport
3.15 Recognising that air transport causes considerable environmental damage and is also less fuel efficient by a large factor particularly to transport by rail or by sea, the Australian Greens consider it important that the environmental costs of air transport are taken into account openly and incorporated into the cost of air travel.
3.16 The Australian Greens believe there are many unexplored possibilities for decreasing the dependence on air travel. One of these is the expansion of teleconferencing. In general, the Australian Greens will support measures such as tax incentives which will encourage people to travel less by air.
3.17 The Australian Greens recognise that bad planning in a number of cases has caused housing areas near airports to have an unacceptable noise level and support moves to remedy such mistakes, for example through modifying flying patterns and airport operations and compensating residents in the most affected areas.
