EMISSIONS FACTS
If you are not convinced that there is a
problem, consider a few facts from the RACV
on vehicle contribution to overall air pollution
(for Victoria):
• Passenger vehicles contribute 47 per cent
of carbon dioxide (CO2) emissions, 40
per cent of nitrogen oxides, 27 per cent of
hydrocarbons and 4 per cent of particles;
• Ten per cent of the total greenhouse gas
emissions (which contribute to climate
change) come from passenger vehicles;
• One litre of petrol emits 2.3kg of CO2 into
the atmosphere, 1L of LPG emits 1.5kg,
and 1L of diesel emits 2.7kg. The average
emission per vehicle is four tonnes per year;
• Transport-related emissions are the second
highest contribution to greenhouse gas
pollution after electricity (mainly from coal).
Overall levels of greenhouse gases have
increased 62.9 per cent since 1990; and
• Forty billion tonnes of CO2 are added to the
environment globally every year.
REDUCING FUEL
CONSUMPTION
The experts have some tips on reducing fuel
consumption and saving money:
• Do not over-rev your engine. Accelerate
gently and slowly, changing gears as soon
as your engine can accommodate the next
highest gear;
• Drive as smoothly as possible. Keep to an
even, steady speed; this can increase fuel
economy by 30 per cent;
• Reduce your speed: 90km/h and below is
the most efficient speed;
• Turn off your engine whenever you are
stopped for more than 30 seconds. Fuel
consumption is reduced more if you turn
off the engine and start it again than if you
keep that engine running;
• If you don’t need to use your vehicle, don’t;
• Keep your tyres properly inflated and your
wheels aligned;
• Minimise wind resistance by removing
exterior attachments when not in use.
Reduce weight by clearing out unnecessary
items from your boot and/or roof rack;
• One-third of hydrocarbon emissions are
due to evaporation. Ensure your fuel cap
fits correctly and that the seal is not worn.
Avoid spillage and overfilling your tank;
Simply running correct tyre pressures
can make a real difference.
