Surprise findings have revealed that Australia's cars are getting less fuel efficient. This is bad news for the hip-pockets of motorists - and for the climate.
New Zealand has proposed new fuel standards, along with a consumer rebates for cleaner cars – paid for by higher costs for high-polluting cars – to cut its rising transport emissions.
How far would you go to limit your carbon footprint?
Electric motors are used in everything from utes to mining trucks – because they pack plenty of oomph.
Labor's ambitious plans to reduce transport emissions will be dead in the water without regulatory CO2 emission standards and real financial and non-financial incentives for buyers.
