CO2 Emissions and Climate Change
The Australian automotive industry is committed to making a strong contribution to national efforts to reduce the impact of global climate change.
Significant improvements in vehicle technology have resulted in new passenger vehicles in the Australian market recording their lowest ever carbon dioxide emissions. The National Average Carbon Emission (NACE) figure for 2011 is 206.6 grams of CO2 per kilometre, down 2.8% compared to the 2010 figure of 212 grams of CO2/km.
This means the average new passenger vehicle sold in Australia is now at least 20% more efficient than it was in 2000. All new passenger cars, SUVs and light commercial utes, vans and buses (up to 3.5 tonne) are included in calculating the NACE figure, including many more vehicle types than CO2 measures used in other parts of the world, including Europe.
This is one of the most significant yearly improvements in the NACE figure and demonstrates the industry's commitment to continue to improve fuel efficiency and reduce carbon dioxide emissions.
The result is a combination of improvements in vehicle technology and a change in consumer buying preferences toward lower emission vehicles.
There has been a strong uptake in new-generation diesel vehicles by consumers. In addition, ongoing efficiency improvements in average emissions from petrol powered vehicles by almost 7% indicates that consumers are continuing to purchase more efficient vehicles across the new vehicle fleet.
