One thought on “Two charts in Australia’s 2023 climate statement show we are way off track for net zero by 2050”
All of these are projected to remain roughly constant between now and 2035, and there is little reason to expect sharp declines after that, at least under current policies. So, on our current trajectory, we are unlikely to get much below 50% of 2005 emissions, let alone net zero, by 2050.
