New report casts fresh doubts over Government emissions proposals


A National Transport Commission report calls into question how new vehicle emissions standards are being developed and highlights the urgent need for real-world vehicle emissions testing.

A report by the National Transport Commission (NTC) which shows Australian are shunning small cars in favour of larger, more powerful vehicles, calls into question the way in which the Federal Government is developing new vehicle emissions standards, and highlights the urgent need for a real-world vehicle emissions testing regime.

Emissions standards which dissuade the purchase of large vehicles and promote the sale of smaller vehicles bring benefits and costs. While the benefits (reduced fuel use) are generally easy to calculate, the costs, in the form of lost vehicle choice and performance are harder to calculate. The Government’s work in this area expressly acknowledges these costs are real, but then fails to make any attempt to calculate them.

The NTC report shows a growing number of Australians value the attributes the Government is failing to factor into its current cost-benefit analysis and suggests the Government’s numbers are getting less accurate by the month.

The NTC’s report, Carbon Dioxide Emissions Intensity for New Australian Light Vehicles 2016, reveals sales of micro, light and small cars have dropped by 45,114 between 2014 and 2016, while sales of SUVs (small, medium, large, upper large) have increased by 88,670.

These new figures underscore the need for the Government to update its modelling and undertake further consultation before finalising its preferred vehicle emissions regulations.

The NTC report also highlights Australian consumers are not provided quality information about the fuel use and carbon dioxide emissions of vehicles they intend to purchase. The AAA has long called for Government’s the Green Vehicle Guide to be improved to include a simple star-rating system and information based upon real-world vehicle emissions testing conducted in Australian conditions.

In the wake of the Volkswagen scandal, jurisdictions across the globe are taking steps to use real world emissions testing to provide more accurate information to consumers about emissions and fuel consumption and such reform should be at the top of the Government’s list of priorities in this area.

The AAA is currently conducting a pilot real-world vehicle emissions program which reveals vehicle fuel consumption and greenhouse gas emissions are up to 60 per cent higher than claimed on the Government’s mandated Fuel Consumption Label, which uses data recorded in laboratory testing.
