In their own words this is only "a massive transformation of the economy", so who cares about the details like, is it possible, and what will it cost?

And of course that all important detail "why bother in the first place?"

The Australian government has just legislated a 43% cut to emissions of a beneficial trace gas, of which Australia makes 1.1% of human output and about 0.05% of the emissions of all the plants, algae and oceans on Earth. We've only got 8 years to do it in and even the head of the our largest national scientific institute admits nearly half of the technologies we need are not even invented yet.

Even the minister calls it "insanely late".

What could possibly go wrong, apart from bankrupting the nation in an effort to change the weather?

Climate target set, now for the tricky bit on cutting emissions
Greg Brown, The Australian

Anthony Albanese's climate change agenda will shift to ­creating two road maps to slash emissions in the transport and ­industrial sectors after his 43 per cent 2030 target became law in a momentous parliamentary vote.

Ahead of the passage of the bill, Climate Change Minister Chris Bowen warned there was a lot of work to be done to ensure Australia lowered emissions by 43 per cent on 2005 levels by 2030.
