Government says new efficiency standards could cut fuel spending by $28bn

New standards could reduce Australia's greenhouse gas emissions by up to 65m tonnes by 2030, government claims

The Turnbull government has opened discussions on new fuel efficiency standards for vehicles which it says could cut consumer fuel spending by up to $28bn by 2040.

Fresh after being forced into a hasty retreat by conservatives over a potential emissions intensity trading scheme which experts argue would allow Australia's electricity sector to reduce emissions at least cost to consumers - the government has regrouped and opened a new policy conversation about regulations that would force car manufacturers to supply cars with more fuel-efficient engines.
