About 10 per cent of the federal government’s emissions reduction target to 2030 could be made by bringing light vehicle emissions standards in line with best practice, ClimateWorks research has found.

Analysis by the organisation found that reducing current Australian performance of 184 grams of CO2 per kilometre to 130gCO2/km in 2020 and 95gCO2/km in 2025 would cut carbon emissions by 100 million tonnes between 2020 and 2030.

ClimateWorks head of implementation Scott Ferraro said the outcome was “easily achievable”.

“The federal government has announced it will reduce carbon emissions by 26-28 per cent by 2030 of which 76 million tonnes of carbon dioxide or eight per cent of the target will be through light vehicle efficiency,” he said.

“Our analysis shows that Australia can improve fuel economy for new passenger and light- commercial vehicles at five per cent per year, matching rates targeted in other markets.”

Mr Ferraro said Australia was one of the few remaining developed countries without light vehicle CO2 emission standards in place.

“Best practice vehicle emission standards can help Australia meet its emissions reduction and energy productivity targets while providing financial savings to motorists and improving national fuel security,” he said.
