New analysis from the Climate Change Authority shows pursuing the deployment of nuclear in Australia’s grid could add at least 2 billion tonnes to national emissions.
This approach would involve a pace of climate action consistent with a global pathway to around 2.6°C of warming, a level at which scientists, economists and governments anticipate major social, economic and environmental harm.
The Climate Change Authority has compared published modelling by the Australian Energy Market Operator (AEMO) and Frontier Economics to understand how the adoption of a nuclear pathway could impact national efforts to reduce emissions.

The analysis finds that a nuclear pathway could see Australia miss the legislated 43% emissions reduction target for 2030 by over five percentage points, and still not achieve this level of reduction by 2035.
Australia would not reach 82% zero emissions electricity until 2042—more than a decade later than current national plans.
“Australia faces a fork in the road and we need to be clear about the choices in front of us,” Climate Change Authority chair Matt Kean says.
“Continuing on Australia’s current pathway and accelerating our progress can deliver rapid cuts to emissions by overhauling our grid with renewables, firming and storage in the next 15 years.
“On the other hand, the nuclear pathway would delay Australia’s necessary transition— keeping coal in the grid for longer and leading to billions of tonnes more emissions in the process.
“Having examined the emissions impacts of these two pathways, the Climate Change Authority’s view is that staying Australia’s current course is the only viable option.
“Prioritising nuclear at this time would be inconsistent with Australia’s national emissions reduction priorities and commitments,” Kean says.

Responding to the analysis, the Climate Council said Opposition leader Peter Dutton’s nuclear scheme risks locking Australia into worsening climate catastrophes, with no credible plan to cut pollution from coal, oil or gas.
Climate Council CEO Amanda McKenzie says, “Mr Dutton knows most Australians want their government to be making progress on climate action. But modelling from the Climate Change Authority shows his nuclear scheme would massively drive up climate pollution and put Australia in breach of its own national law, and international law. Mr Dutton himself has warned that failing to meet our global climate commitments would hurt our own economy and cost Australians jobs.
“The Coalition is out of step and out of touch with the majority of everyday Australians, who overwhelmingly voted for climate action at the last election and want to ditch climate pollution for clean power.”
