Beneath the Wisteria

If you despair of Australia’s lacklustre climate policies, you might take heart from the Greens’ stated goal of limiting global warming to 1.5℃. But are the party’s own policies up to the job?

Shortly after announcing this target late last year, the Greens launched an ambitious renewables policy, promising to achieve 90% renewable electricity by 2030 and save money in the process.

But as wonderful as it sounds, even this plan is insufficient to meet a 1.5℃ target.

The arithmetic is simple. According to the Intergovernmental Panel on Climate Change (IPCC), to preserve a two-thirds chance of avoiding 1.5℃ warming, future carbon dioxide emissions must not exceed 200 billion tonnes. As annual global emissions are now around 40 billion tonnes, we will blow the budget within five years.
