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.
Nations are struggling to agree on how international carbon trading should work under the Paris accord. A weak result would undermine global efforts to fight climate change.

Australia’s entire coal fleet will retire in the next few decades. The federal government’s response to the Hazelwood coal plant closure has left a mess – it must do better.
It’s long been known that our diet choices help determine our carbon footprint. But do you know which of your favourite foods are the most water-hungry?
History has told us Aboriginal people in Tasmania almost exclusively occupied open plains. Revelations to the contrary could transform modern conservation.
New research shows that warming by more than 2°C could be a tipping point for Antarctica’s ice sheets, resulting in widespread meltdown and changes to the world’s shorelines for centuries to come.
Australian supermarkets and fast food chains will soon be stocking a homegrown meat alternative that tastes and feels like meat and even sizzles on the barbecue.
