If you were born in 1989 or after, you haven’t yet voted in an election that’s seen a Prime Minister serve a full term.

Some point to social media, the online stomping grounds of digital natives, as the cause of this. As Emma Alberici pointed out, Twitter launched in 2006, the year before Kevin ’07 became PM.

Some blame widening political polarisation, of which there is evidence social media plays a crucial role.

If we take a look though, the thing that keeps killing our PMs’ popularity in the polls and party room is climate and energy policy. It sounds completely anodyne until you realise what a deadly assassin it is.

Rudd

Kevin Rudd declared, “Climate change is the great moral challenge of our generation”. This strategic focus on global warming contributed to him defeating John Howard to become Prime Minister in December 2007. As soon as Rudd took office, he cemented his green brand by ratifying the Kyoto Protocol, something his predecessor refused to do.

There were two other major efforts by the Rudd government to address emissions and climate change. The first was the Carbon Pollution Reduction Scheme(CPRS) led by then environment minister Penny Wong. It was a ‘cap and trade’ system that had bi-partisan support from the Turnbull led opposition party… until Turnbull lost his shadow leadership to Abbott over it. More on this soon.

Then there was the December 2009 United Nations climate summit in Copenhagen, officially called COP15 (because it was the fifteenth session of the Conference of Parties). Rudd and Wong attended the summit and worked tirelessly with other nations to create a framework for reducing global energy consumption. But COP15 was unsuccessful in that no legally binding emissions limits were set.

Only a few months later, the CPRS was ditched by the Labor government who saw it would never be legislated due to a lack of support. Rudd was seen as ineffectual on climate change policy, the core issue he championed. His popularity plummeted.

Gillard

Enter Julia Gillard. She took poll position in the Labor party in June 2010 in what will be remembered as the “knifing of Kevin Rudd”.

Ahead of the election she said she would “tackle the challenge of climate change” with investments in renewables. She promised, “There will be no carbon tax under the government I lead”.

Had she known the election would result in the first federal hung parliament since 1940, when Menzies was PM, she may not have uttered those words. Gillard wheeled and dealed to form a minority government with the support of a motley crew – Adam Bandt, a Greens MP from Melbourne, and independents Andrew Wilkie from Hobart, and Rob Oakeshott and Tony Windsor from regional NSW. The compromises and negotiations required to please this diverse bunch would make passing legislation a challenging process.

To add to a further degree of difficulty, the Greens held the balance of power in the Senate. Gillard suggested they used this to force her hand to introduce the carbon tax. Then Greens leader Bob Brown denied that claim, saying it was a “mutual agreement”. A carbon price was legislated in November 2011 to much controversy.

Abbott went hard on this broken election promise, repeating his phrase “axe the tax” at every opportunity. Gillard became the unpopular one.

Rudd 2.0

Crouching tiger Rudd leapt up from his grassy foreign ministry portfolio and took the prime ministership back in June 2013. This second stint lasted three months until Labor lost the election.

Abbott

Prime Minister Abbott launched a cornerstone energy policy in December 2013 that might be described as the opposite of Labor’s carbon price. Instead of making polluters pay, it offered financial incentives to those that reduced emissions. It was called the Emissions Reduction Fund and was criticised for being “unclear”. The ERF was connected to the Coalition’s Direct Action Plan which they promoted in opposition.

Abbott stayed true to his “axe the tax” slogan and repealed the carbon price in 2014.

As time moved on, the Coalition government did not do well in news polls – they lost 30 in a row at one stage. Turnbull cited this and creating “strong business confidence” when he announced he would challenge the PM for his job.

Turnbull

After a summer of heatwaves and blackouts, Turnbull and environment minister Josh Frydenberg created the National Energy Guarantee. It aimed to ensure Australia had enough reliable energy in market, support both renewables and traditional power sources, and could meet the emissions reduction targets set by the Paris Agreement. Business, wanting certainty, backed the NEG. It was signed off 14 August.

But rumblings within the Coalition party room over the policy exploded into the epic leadership spill we just saw unfold. It was agitated by Abbott who said:

“This is by far the most important issue that the government confronts because this will shape our economy, this will determine our prosperity and the kind of industries we have for decades to come. That’s why this is so important and that’s why any attempt to try to snow this through … would be dead wrong.”

Turnbull tried to negotiate with the conservative MPs of his party on the NEG. When that failed and he saw his leadership was under serious threat, he killed it off himself. Little did he know he would go down with it.

Peter Dutton continued with a leadership challenge. Turnbull stepped back saying he would not contest and would resign no matter what. His supporters Scott Morrison and Julie Bishop stepped up.

Morrison

After a spat over the NEG, Scott Morrison has just won the prime ministership with 45 votes over Dutton’s 40.

Killers

We have a series of energy policies that were killed off with prime minister after prime minister. We are yet to see a policy attract bi-partisan support that aims to deliver reliable energy at lower emissions and affordable prices. And if you’re 29 or younger, you’re yet to vote in an election that will see a Prime Minister serve a full term.
