With a nip and a bit of tuck Turnbull can bring a touch of green to Direct Action

The Coalition's climate policy holds a hidden key which will allow its new leader to set tougher baselines that emitters are not allowed to exceed

Malcolm Turnbull once said he didn't want to lead a party that wasn't as committed to climate action as he was. Now he does.

Climate policy cost Turnbull the Liberal leadership in 2009 when he backed Kevin Rudd's emissions trading scheme. He had to promise not to try to reintroduce an emissions trading scheme to gather the support he needed to win it back.
