Concerns about greenhouse gases and pollution are registering with Australian motorists, but many are unsure about the effect vehicles are having on the environment, according to a recent survey.
The survey, conducted by the Australian Automobile Association, shows that while 79 per cent of drivers are concerned about the effects of their cars on the environment, they believe that their vehicles contribute, on average, 36 per cent of Australia’s total greenhouse gas emissions. The National Greenhouse Gas Inventory lists the total contribution of road transport at 12.6 per cent of national emissions, and passenger vehicles contributing approximately 7.8 per cent.
Stationary energy production remains the largest contributor of greenhouse gases at approximately 51 per cent, with agriculture coming in second at 17 per cent.
46 per cent of the 1500 drivers surveyed believed they had a “rough idea” of the contribution of vehicles to greenhouse gas emissions, but many overestimated the contribution. Younger drivers in particular were more likely to overestimate the contribution of passenger vehicles, with their average estimate just over 35 per cent.
Despite the relatively smaller contribution of transport, the sector is the fastest growing contributor to greenhouse gas emissions, having increased 30 per cent between 1990 and 2005. Passenger vehicle emissions have increased 25 per cent in the same period.
