How could Australia actually get to net zero? Here’s how
Every bit of warming matters if we want to avoid the worst impacts for climate change, as the latest report from the Intergovernmental Panel on Climate Change shows.
In 2020, we released modelling showing how Australia could get to net zero faster – and keep the Paris Agreement goal of holding warming to 1.5°C in play. Our new update shows this is still the case.
This week, we released our latest modelling based on cutting emissions in line with the 2015 Paris Agreement, which set an upper limit on warming of well below 2°C, with a commitment to strive for the lower harm limit of 1.5°C.
At present, the government’s 2030 goal is a 43% reduction from 2005 levels, with plans to set a further target for 2035 soon. Our new modelling of 1.5°C and well-below-2°C (1.8°C) pathways shows we must increase the pace of emissions cuts to between 48–66% for 2030 and 61%–85% for 2035.
This means Australia would reach net zero emissions by 2039, around a decade sooner than the current target of net zero by 2050. Our research shows this is possible.
