Electrifying transport needs bigger changes than another high-end electric car.
In New Zealand, where more than 80% of electricity is renewable, the carbon footprint of electric cars is 62% lower than that of fossil cars. But their lithium battery has other environmental impacts.
We can't decarbonise the whole transport sector with just batteries - sustainable fuels are essential.
Unlike a car, you can't just stick a battery-powered engine in a plane and expect it to fly. Despite that, small planes might be the future of electric flight.
New Zealand is introducing new procurement rules to better link government spending with climate change policy. The first target is to reduce emissions profile of the government's vehicle fleet.
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.
Academic experts on how the humble car could evolve to become an unlikely hero in the global fight against climate change.
To become an attractive prospect for electric car manufacturers, the UK needs to sort out its supplies of rare earths – Brexit, or no Brexit.
Electricity consumption will grow as more people switch to electric cars – but this could drive up emissions, unless power is sourced from renewables.
When it comes to eliminating greenhouse gas emissions from transport, the future is already here on small islands.
The year 2030 may not seem far away, but a decade is a long time in technological terms. Widespread automation, electrification, and connectivity are set to revolutionise the car of the future.
Chinese electric vehicle sales already amount to more than half of the world's total – and car makers and battery manufacturers are working hard to grow even faster.
Vehicles in Canada are big, heavy and guzzle a lot of gasoline.
Electric motors are used in everything from utes to mining trucks – because they pack plenty of oomph.
Putting driverless cars on the road safely is hard enough. Doing it in the air is much more difficult.
Concerns about the strain electric cars can put on the electricity grid are not unfounded, but there are some relatively simple fixes available.
The transport sector is the fastest growing contributor of greenhouse gases. Electric vehicles are a cost-effective solution.
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.
Researchers have found a way to evaluate how energy-efficient electric vehicles are, and compare the sizes and costs of batteries for different models.
At the moment, fuel taxes pay for most of the maintenance of US roads, bridges and highways. What happens when the majority of cars no longer run on gasoline?
