Will bolshie Nationals or Joe Biden have more sway with Morrison on 2050 emissions target?
Many observers have been assuming Scott Morrison's strategy is to creep towards endorsing the 2050 target of net zero emissions, finally embracing it before the Glasgow climate conference in November. But this week's developments suggest the Prime Minister might have to adopt another course. He could stay with his present position, which has the target as an aspiration he surrounds with a web of subsidiary policies, such as the multiple bilateral technology agreements he announced while he was overseas. Morrison's present commitment, reiterated in his major speech in Perth before leaving Australia, is to reach net zero "as soon as possible, preferably by 2050". In London, British Prime Minister Boris Johnson, in an intriguing but unexplained moment at their joint news conference, stated Morrison had "declared for net zero by 2050". Of course he hadn't, and Johnson was aware of that  he has been urging him to do so. We don't know whether there was intent in Johnson's comment, or just sloppiness. In the mouth of a politician, the word "preferably" is like that handy phrase "the government plans to " (or "has no plans to "). It is cheap coinage. It certainly wouldn't buy much in Glasgow. But it is useful and it may be the coinage Morrison will need to continue to deal in. Remember we are talking here about political reality, not what is the best policy, which clearly would be to sign up to the target. In the shadow of Glasgow  We've thought Morrison would want to shift before Glasgow so Australia would have a more credible position internationally, respond to the pressure from the US and Britain, and minimise isolation. That's apart from the electoral implications surrounding an issue many voters feel strongly about. But Morrison this year has already worn the awkwardness of taking Australia's weak position through Joe Biden's "virtual" climate summit and maintaining it during his trip to the G7 meeting. And even if he changed for Glasgow, other countries wouldn't be convinced. There'd be no foreign applause. The sharp point of the debate has moved from 2050 to the medium term, and Morrison won't make Australia's 2030 targets more ambitious (though he'll argue it will exceed them and possibly even project to 2035). The US and the UK have leaned on Morrison, and he hasn't firmed his 2050 stand. Now, at home, it's increasingly looking dangerous for him to do so, even though work is under way to map out Australia's emissions technology plans and what that means for reductions. British Prime Minister Boris Johnson greets his Australian counterpart Scott Morrison with an elbow bump outside No 10 Downing Street in London this week. ( Reuters: Henry Nicholls  Risk and reward  It's a risk-benefit judgment for Morrison, and the risk of moving could be high. Not all the Nationals oppose the 2050 target but enough of them do  and very strongly  to create a serious obstacle for the PM. The opponents within the minor party are bolshie and willing to fight. Nationals Senate leader Bridget McKenzie was a minister until she became the fall girl in the sports rorts affair. She doesn't owe anything to Morrison or her leader, Michael McCormack. McKenzie was on Sky News with Alan Jones this week. "The National Party is the second party in this Coalition government. [It] has not signed up to net zero anything at any time and we'll take a lot of convincing that that is actually the destination we need to get to," she said. "Because we know it'll be our miners, our farmers, our manufacturers that will be paying the price for all this posturing. "We will not let our people be put under the bus to chase some fake ambition to appease overseas masters." In normal circumstances, Morrison might expect the Nationals' leadership to be able to get a desired result  by pointing out there could be benefits for farmers  regardless of noisy dissidents. But nothing is normal in the Nationals. It's a wasps' nest. Poke a stick in and anything could happen. McCormack, with a tenuous grip on the leadership, could easily be stung to death. McCormack knows this. Pressed in a Wednesday podcast with The Conversation, he said the Nationals wouldn't be agreeing to the target this year. When it was put to him, "we can be sure that the Nats would not embrace that target?" he replied: "Correct." Deputy Prime Minister Michael McCormack doesn't have a strong hold on the Nationals' leadership. ( AAP: Mick Tskikas  Resources Minister Keith Pitt told the ABC on Thursday that for the government policy to change to endorsing net zero by 2050 would require the Nationals' agreement, "and that agreement has not been reached or sought". Asked what the mood of their party room would be now, he said: "I think they'd be unsupportive, but we are yet to have that discussion." If Morrison wants to trigger "that discussion", it could be very messy and divisive in the latter months of this year. What suits the country may not suit the city  Failing to embrace the target would not do the Coalition any harm in regional seats in Queensland  in fact it would maximise the difference with Labor. It would obviously be unhelpful. But many of those for whom climate is a major vote-changing issue may have shifted their vote anyway. The prospects of independent Zali Steggall retaining Warringah would probably be assisted by the government failing to endorse 2050. But the Liberals are not reckoning on regaining this seat unless former NSW premier Mike Baird runs, and he has resisted that. So while there would be clear costs in staying with the weasel words, "as soon as possible" and "preferably", they are arguably not as great as a potential blow-up in the Nationals that could have unforeseen consequences. Greater if he were there than if he just sent Foreign Minister Marise Payne and Energy Minister Angus Taylor, who wouldn't be noticed. He'd remember Kevin Rudd's presence at Copenhagen in 2009 played badly for him. He'd note Tony Abbott did not attend the 2015 Paris conference. Julie Bishop, as foreign minister, led the Australian delegation. Morrison has said he hopes to go to Glasgow. It would be a matter of scheduling. He'll be in Rome for the G20 at the end of October. The Glasgow conference, which runs from November 1-12, is expected to have a leaders' segment at the start, facilitating them going straight from the G20. If he attends, Morrison will be armed with a heap of policy on technology and how it will cut emissions. But he still mightn't have that hard and fast 2050 target in his kit bag.
