Australian carbon tax is levied

Australians now pay AU$23 per tonne of CO2.

The Australian carbon tax came into effect on Sunday, at a price of AU$23 per tonne of CO2. The tax is supported by just a third of Australians, and has driven support of the Labor party, which leads the coalition which introduced it, to a forty year low, but many campaigners consider it a forward-looking measure.

The price will rise by 4 per cent a year for the next two years, before the tax becomes an emissions trading scheme in 2015. From then on, the cost of a tonne of carbon will be set by the market. A number of concessions had to be made to get the tax through the legislature at all, including exempting agriculture entirely and issuing large rebates – of up to 94.5 per cent – to industries like steel and aluminium mining, which take the largest hits from being undercut by foreign businesses.

The target is to reduce the countries emissions by 5 per cent by 2020, and 80 per cent by 2050, from 2000 levels. As it stands, Australians create more CO2 per capita than any other developed country. The country is responsible for 1.5 per cent of global greenhouse gas emissions, just 0.2 per cent less than Britain, which has three times the population.

The tax itself has been set at a relatively low figure. The Stern review, the seminal 2006 report by the economist Nicholas Stern, is commonly thought to have lowballed the damaging effects of climate change, and still suggested that the social cost of a tonne of carbon was in the order of $85 (AU$83). It is also intended to be revenue neutral, and in order to avoid what would otherwise be regressive effects, most of the money is being used to effect major cuts to income tax. The threshold for income tax raised by over $10,000 to $18,200 yesterday, and even direct payments into bank accounts under the name "Clean Energy Advance". Overall, any household earning udner $80,000 should be better off after the changes.

All of which appears to have done nothing for the popularity of the tax, which is hurt by the sheer strength of climate scepticism in Australia. Not only is the opposition leader, Tony Abbott, a climate skeptic, but the views of right-wing shock-jock Alan Jones are representative of a relatively large section of the population:

What [Prime Minister Julia Gillard] has done ... is to diminish the image of parliament and politics in the eyes of the public. The notion of global warming is a hoax, this is witchcraft. . . There are stacks and stacks of eminent scientists all over the world who've argued it's witchcraft. . . I have interviewed every one of them on my program and not one syllable they have uttered has been produced on any other media outlet anywhere in Australia. . . There is a conspiracy in this country to deny the other side.

Nonetheless, the government – made up of a coalition between the Labor party and the smaller Greens – has hope for the policy. Greens leader Christine Milne says:

I think people will shrug their shoulders and say 'what was all that about'. People will start to get angry with the Coalition [the opposition party], for having made all the claims they've made.

Even Milne seems to be anticipating a Coalition victory in the next elections, and no surprise. If there were an election today, they would win in a landslide. But as she says, the tax is in place, and it may be that by the time of the next election, there are more important questions to answer.

Why Labour's rise could threaten Nicola Sturgeon's independence dream

As the First Minister shelves plans for a second vote, does she join the list of politicians who bet on an anti-Brexit dividend that failed to materialise?

The nights are getting longer, and so are generations. The independence referendum sequel will happen after, not before the Brexit process is complete, Nicola Sturgeon announced yesterday.

It means that Scottish Remainers will not have the opportunity to seamlessly move from being part of a United Kingdom in the European Union to an independent Scotland in the European Union. Because of the ongoing drama surrounding Theresa May, we've lost sight of what a bad night the SNP had on 8 June. Not just because they lost 21 of the 56 seats they were defending, including that of their leader in Westminster, Angus Robertson, and their former leader, Alex Salmond. They also have no truly safe seats left – having gone from the average SNP MP sitting on a majority of more than 10,000 to an average of just 2,521.

As Sturgeon conceded in her statement, there is an element of referendum fatigue in Scotland, which contributed to the loss. Does she now join the list of politicians – Tim Farron being one, and Owen Smith the other – who bet on an anti-Brexit dividend that failed to materialise?

I'm not so sure. Of all the shocks on election night, what happened to the SNP was in many ways the least surprising and most long-advertised. We knew from the 2016 Holyrood elections – before the SNP had committed to a referendum by March 2019 – that No voters were getting better at voting tactically to defeat the SNP, which was helping all the Unionist parties outperform their vote share. We saw that in the local elections earlier this year, too. We knew, too, that the biggest beneficiaries of that shift were the Scottish Conservatives.

So in many ways, what happened at the election was part of a bigger trend that Sturgeon was betting on a wave of anger at the Brexit vote. If we get a bad Brexit deal, or worse, no deal at all, then it may turn out that Sturgeon's problem was simply that this election came a little too early.

The bigger problem for the Yes side isn't what happened to the SNP's MPs – they can undo that with a strong showing at the Holyrood elections in 2021 or at Westminster in 2022. The big problem is what happened to the Labour Party across the United Kingdom.

One of Better Together's big advantages in 2014 is that, regardless of whether you voted for the Conservatives, the Liberal Democrats or the Labour Party, if you believed the polls, you had a pretty reasonable expectation that your type of politics would be represented in the government of Britain sometime soon.

For the last two years, the polls, local elections and by-elections have all suggested that the only people in Scotland who could have that expectation were Conservatives. Bluntly: the day after the local elections, Labour and the Liberal Democrats looked to be decades from power, and the best way to get a centre-left government looked to be a Yes vote. The day after the general election, both parties could hope to be in government within six months.

As Tommy Sheppard, the SNP MP for Edinburgh East, observed in a smart column for the Herald after the election, one of the reasons why the SNP lost votes was that Corbyn's manifesto took some of the optimistic vote that they gobbled up in 2014 and 2015.

And while Brexit may yet sour enough to make Nicola Sturgeon's second referendum more appealing on that ground, the transformation in Labour's position over the course of the election campaign is a much bigger problem for the SNP.
