Is that a carbon tree? Or just another policy thought bubble?

If green groups and political opponents were unimpressed with the Turnbull government’s 2017 Review of Climate Change Policies yesterday, so was the Twittersphere.

A day after the Coalition made its pre-Christmas climate data dump – which showed a disturbing rise in emissions – and announced that another two right-wingers had been appointed to cabinet by the man coal magnate Gina Reinhardt rates as Australia’s greatest farmer – Barnaby Joyce – reviews of the review started to surface.

Journalist Adam Morton Tweeted that it was “transparently political: uses the minister’s language, doesn’t bother with new policies, suggests biz can emit more.” Another Tweet wondered “who wrote this work of fiction?”

But our favourite Tweet was from Michael Mazengarb, who wondered what secret, magic technology was depicted in the graphic pictured below and above, taken from the 52-page review.

Suggestions so far have included a giant balloon, a bubble wand, and a front loader washing machine for cleaning coal.

We thought we’d open the question up to RenewEconomy readers: What is this mysterious carbon offset thingamy that will deliver zero emissions? Any guesses?

Update: we asked the minister’s office. Apparently it is a tree. We’re not to sure why the leaves all fell to bottom left.
