Should Australia abandon Net Zero 2050

None of the Top 4 emitters in the world are signed up to 2050, between them (US, China, India, Russia) they account for ~60% of total global emissions.

So the question therefor begs, should Australia abandon Net Zero 2050 for a more realistic and achievable target that isn't at the detriment of Australia's sovereignty, prosperity and productivity?

Context: According to Labor's own numbers we are well behind their emissions reduction targets and in the past 3 years have seen no meaningful reduction in emissions, despite a 50% increase in energy prices.
