Having a carbon price is linked to lower emissions growth. A larger price cuts emissions by more.
Labor continues to be hung up on a decade-old Greens' decision to oppose an emissions trading scheme in 2009. But responsibility for Australia's climate policy void lies elsewhere.
With consultation underway to improve the New Zealand emissions trading scheme, experts argue that a reserve price on emissions units could help rebuild confidence in low-emission investment.
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.

While Tony Abbott's London climate speech has been widely criticised, research suggests his views have long had a sympathetic ear in Australia's coal heartland.
New Zealand is a trailblazer for emissions trading, which could help drive a low-emission transformation, both domestically and overseas, in a post-Paris world.
Labor has been criticised for vacillating about about its 50% renewable energy ambition. But its proposed emissions intensity scheme could boost green energy without any hard target at all.
In a year of coral bleaching, power blackouts, electricity arguments and Donald Trump, 2016 made the previous year's climate of environmental optimism rather difficult to maintain.
Liberal MP Craig Kelly said businesses and households in Australia are paying twice as much as Americans for their electricity. Is that true?

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.
