The New Vehicle Efficiency Standard Act 2024 (NVES) is an Australian act of parliament that imposes emissions limits on vehicles.
The law was implemented on 1 January 2025, with it coming into effect on 1 July 2025.
Manufactures are fined A$100 for every gram of carbon dioxide per kilometre (g/km of CO<sub>2</sub>) average over the limit, and credits for every g/km of CO<sub>2</sub> under the limit. Credits can be sold to other manufactures or be banked for future years. Vehicles with a gross vehicle mass over 4.5 tonnes are exempt from the bill.
Fines will be first issued in 2028, for the 2025 reporting period, called interim emissions value (IEV) which ran from 1 July to 31 December 2025. The results of the 2025 IEV will be publicised in February 2026.
The bill has two classifications of vehicles with emission targets. Type 1 vehicles: passenger cars and SUVs. Type 2 vehicles: light commercial vehicles, such as utes and vans.
SUVs can count as a Type 2 vehicle if they are built with four wheel drive on a body on frame and have three tonnes braked towing capacity.
In 2025, Ford Australia and Isuzu dropped their 4ÃÂ2 variants of their Ford Everest and Isuzu MU-X SUVs in Australia due to not meeting emissions requirements for passenger vehicles. In 2026, Kia discontinued the 3.5 liter V6 petrol engine powered versions of the Kia Carnival MPV and Kia Sorento SUV models in Australia as the engine is unable to be modified to meet 2024 NVES regulations mandated on all new passenger vehicles sold in Australia from 2026.
