Is the double-dip no more? Does it matter?

Maybe, and no. No it does not.

Last Friday, the ONS revised its estimates of the size of British construction output over 2012. It now thinks that the construction sector shrank by 5 per cent in the first quarter of that year, compared to the 5.4 per cent contraction it had previously estimated. (Although that's good news, the picture is less rosy for the other three quarters of the year, which were all revised downwards.)

That upward revision would be enough to bring the overall growth figure for Q1 2012 to exactly zero; hence the Saturday Mail story dubbing it "The double-dip that never was! Osborne gets a surprise boost as 'growth' was 0.0% rather than -0.1%".

There are two things to say at this point. Firstly, the nitpicking: the ONS is also due to announce the latest revisions to the service sector on the 23rd of this month (estimates for production, the third main component, were published on the 9th). Those revisions could be in either direction, and, given the size of services in the overall economy, it would not take a large downward swing to wipe out the "gains" from production. So it's too early to say for certain that the double-dip has been erased.

But the broader point is that it does not matter, and has never mattered, whether the economy grew by 0.1 per cent, didn't grow, or shrank by 0.1 per cent. What is important is that Britain has stagnated for the better part of two years running now. Anaemic growth is just as bad as a mild recession – and in some ways worse, because while a recession may be expected to spring back into recovery at some point, stagnation can last for decades. Just ask Japan.

That's the reason I've focused on the description of our economy as "corrugated". We focus so much on the ups and downs, with cheers alternating on either side of the aisle, that we neglect to take a step back and look at what the overall trend is. The fact that the economy was precisely stagnant in the first quarter of 2012 doesn't change that trend for the better; it makes it overwhelmingly clear that stagnation remains the reality we live in.

Of course, some will claim that this revision matters anyway, because it means that we never had the technical recession which garnered so much bad press last year. But – you can guess where this is going – technical recessions are an alarmingly misleading thing to focus on in an economic environment like ours. Because, again, in a corrugated economy, whether a particular consecutive pair of quarters displays slightly negative growth is basically down to chance. What is not down to chance is the overall pattern.

This is what our economy looks like, right now:

Until and unless that flat black line stops being quite so astonishingly flat, there is little to celebrate. Arguing about the size of the kinks within it is little more than trivia.

The rise of the green mayor – Sadiq Khan and the politics of clean energy

At an event at Tate Modern, Sadiq Khan pledged to clean up London's act.

On Thursday night, deep in the bowls of Tate Modern’s turbine hall, London Mayor Sadiq Khan renewed his promise to make the capital a world leader in clean energy and air. Yet his focus was as much on people as power plants – in particular, the need for local authorities to lead where central governments will not.

Khan was there to introduce the screening of a new documentary, From the Ashes, about the demise of the American coal industry. As he noted, Britain continues to battle against the legacy of fossil fuels: “In London today we burn very little coal but we are facing new air pollution challenges brought about for different reasons." 

At a time when the world's leaders are struggling to keep international agreements on climate change afloat, what can mayors do? Khan has pledged to buy only hybrid and zero-emissions buses from next year, and is working towards London becoming a zero carbon city.

Khan has, of course, also gained heroic status for being a bête noire of climate-change-denier-in-chief Donald Trump. On the US president's withdrawal from the Paris Agreement, Khan quipped: “If only he had withdrawn from Twitter.” He had more favourable things to say about the former mayor of New York and climate change activist Michael Bloomberg, who Khan said hailed from “the second greatest city in the world.”

Yet behind his humour was a serious point. Local authorities are having to pick up where both countries' central governments are leaving a void – in improving our air and supporting renewable technology and jobs. Most concerning of all, perhaps, is the way that interest groups representing business are slashing away at the regulations which protect public health, and claiming it as a virtue.

In the UK, documents leaked to Greenpeace’s energy desk show that a government-backed initiative considered proposals for reducing EU rules on fire-safety on the very day of the Grenfell Tower fire. The director of this Red Tape Initiative, Nick Tyrone, told the Guardian that these proposals were rejected. Yet government attempts to water down other EU regulations, such as the energy efficiency directive, still stand.

In America, this blame-game is even more highly charged. Republicans have sworn to replace what they describe as Obama’s “war on coal” with a war on regulation. “I am taking historic steps to lift the restrictions on American energy, to reverse government intrusion, and to cancel job-killing regulations,” Trump announced in March. While he has vowed “to promote clean air and clear water,” he has almost simultaneously signed an order to unravel the Clean Water Rule.

This rhetoric is hurting the very people it claims to protect: miners. From the Ashes shows the many ways that the industry harms wider public health, from water contamination, to air pollution. It also makes a strong case that the American coal industry is in terminal decline, regardless of possibile interventions from government or carbon capture.

Charities like Bloomberg can only do so much to pick up the pieces. The foundation, which helped fund the film, now not only helps support job training programs in coal communities after the Trump administration pulled their funding, but in recent weeks it also promised $15m to UN efforts to tackle climate change – again to help cover Trump's withdrawal from Paris Agreement. “I'm a bit worried about how many cards we're going to have to keep adding to the end of the film”, joked Antha Williams, a Bloomberg representative at the screening, with gallows humour.

Hope also lies with local governments and mayors. The publication of the mayor’s own environment strategy is coming “soon”. Speaking in panel discussion after the film, his deputy mayor for environment and energy, Shirley Rodrigues, described the move to a cleaner future as "an inevitable transition".

Confronting the troubled legacies of our fossil fuel past will not be easy. "We have our own experiences here of our coal mining communities being devastated by the closure of their mines," said Khan. But clean air begins with clean politics; maintaining old ways at the price of health is not one any government must pay. 

'From The Ashes' will premiere on National Geograhpic in the United Kingdom at 9pm on Tuesday, June 27th.
