"straw argument madam..... plenty of other jurisdictions are scaling back on emissions. many with tighter conditions than Aus."
With great ease I'll neuter your flawed straw man assertion by pointing out that even more jurisdictions are increasing emissions than reducing them, notably the likes of those that step into the market to replace the production capacity being shuttered in those jurisdictions claiming virtue by acting in a manner that at face value reduces emissions.
In a great many cases, it is merely affluent western countries effectively acting to trans-locate dirty industries to developing countries.
As such, it is tantamount to a form of "environmental imperialism", i.e., we citizens of rich countries still demand the industrially-generated products, but we just don't want to make them here, so they can simply be made in poor countries.
I'm no fan of Marx in general, but he had some valid reservations, rightly observing that Capitalism has the knack of making its ill effects invisible by displacing them elsewhere.
"Green" Capitalism perfectly fits Marx's narrative of having the effect of trans-locating dirty industries to somewhere where they aren't able to be observed.
