Prime Minister Malcolm Turnbull has abandoned the emissions-reduction component of his signature energy policy, in the latest chapter of a brutal decade-long saga for Australian climate policy.
Barnaby Joyce had a long history of opposing climate action. His successor Michael McCormack seems to think the same way, despite climate being a growing threat to the Nationals' rural voters.
Australia's flagship climate policy, has spent more than $2 billion on emissions reductions, yet big businesses could wipe all this out. Time to resurrect the idea of a simple carbon tax.

New technologies that can help us to meet climate change targets are struggling to see the light of day. Incentives need to be fixed, and carbon pricing is at the heart of the matter.
Two members of the Climate Change Authority offer an alternative view on its latest report, arguing that the recommendations are not in line with Australia's international climate obligations.
A new "toolkit" of suggested climate policies looks politically feasible, but it's too complicated and not ambitious enough to drive a real move to a low-carbon economy.
