Australian passenger vehicles are emitting 50% more carbon dioxide than the average of the world's major markets. And the real-world situation is even worse than official figures show.for road transport. To hit the target, policies to cut vehicle emissions have to be intensified and supported by a range of other policies.. Each option would set a national limit on grams of CO₂ that can be emitted for each kilometre driven, averaged across all new cars sold.

The briefing paper used previous research into Australian and international real-world emissions performance to create a more accurate comparison. Whereas the official figures suggest newly sold Australian passenger vehicles have relatively high emissions, at least they appear to have improved each year. The picture is very different when we look at on-road emissions.suggest emissions from newly sold Australian passenger vehicles have actually been rising since 2015.

For instance, the official Australian test protocol is outdated and increasingly underestimates on-road emissions. It provides an unrealistic and skewed picture, undermining effective emission reduction. The government says it intends to adopt a more realistic test protocol.
