To prevent this putting their industries at a disadvantage against imports from countries that don’t impose a similar carbon price on their own industries, the Europeans plan to use a “carbon border adjustment mechanism”, a tax on imported cement, fertilisers, aluminium and iron and steel to bring their carbon costs up to those faced by local producers.

So there’s no reason for any of us who believe climate change is real and must be countered to have any sympathy for the Abbott-Turnbull-Morrison government. All its sins of expedience and populist politicking are finding it out.

This not only levels the playing field for local industry, it eliminates the incentive for producers to move their production to countries without carbon pricing.

These problems are ones we ourselves worried about when designing Kevin Rudd’s original carbon pollution reduction scheme (which the Coalition and the Greens voted down in 2010) and Julia Gillard’s carbon pricing scheme of 2012 (which was repealed by Abbott in 2014).

So what the Europeans want to do can’t honestly be called protectionism. It bears no similarity with the new import duties China’s imposing on some of our exports.

What’s true is that it’s a messy but necessary way of solving the “wicked” problem of climate change which, being global, can only be fixed by all of the world’s big emitting countries doing their bit. This is why we can expect many other big countries – starting with America, and maybe extending to Japan − to impose similar carbon border taxes on those countries that try to freeload on those doing the right thing, while helping to sabotage the good guys’ efforts in the process.

So there’s no reason for any of us who believe climate change is real and must be countered to have any sympathy for the Abbott-Turnbull-Morrison government. All its sins of expedience and populist politicking are finding it out. It took a bet that the rest of the world wouldn’t get serious, and we lost.

The point is, had we stuck with either the first or the second version of our own emissions trading scheme – which was actually designed to fit with the Europeans’ scheme – we wouldn’t have this problem.

By now our exporters would be paying our carbon tax to our government (or, if they weren’t yet, we could easily fix it) rather than paying the same tax to foreign governments. Why’s that a good idea?

From the beginning, this government has used climate change as nothing more than an opportunity to attack the other side of politics by pushing populist delusions that taxes are always and everywhere a bad thing. Bad for the economy. Yeah, sure.
