The Coalition’s pledge to build seven nuclear reactors, if elected, would represent a huge shift in energy policy for Australia. It also poses serious questions about whether this nation can meet its international climate obligations.
If Australia is to honour the Paris Agreement to limit global average temperature rise to 1.5˚C by mid-century, it can emit about 3 billion tonnes, or gigatonnes, of carbon dioxide (CO₂) over the next 25 years. This remaining allowance is what’s known as our “carbon budget”.
My colleagues and I recently outlined the technological options for Australia to remain within its carbon budget. We did this using a tool we developed over many years, the “One Earth Climate Model”. It’s a detailed study of pathways for various countries to meet the 1.5˚C goal.
