A carbon tax may not actually do a whole lot for emissions

There's a chicken/egg problem at work.

A carbon tax is most economists' favourite method of dealing with climate change. It is exactly the sort of simple, market-driven intervention that they tend to like: set a price per tonne of carbon emitted which is equal to the value of the damage that tonne does to the climate, and then sit back and what businesses and consumers react. Some may cut their usage; some may switch to low-carbon sources of energy, which suddenly become cheaper comparatively; and some may choose to just pay the extra cost (what happens in that last situation is debatable – some think the money should just count as general taxation, others that it should be put towards climate change prevention and mitigation).

The Washington Post's Brad Plumer suggests that it may not work as well as we would hope, however. He reports on a recent MIT study looking at the likely effect of a $20 a ton carbon tax in the real world – the value proposed by a pair of MIT researchers last month.

Plumer writes:

Sebastian Rausch and John M. Reilly of the MIT Global Change Institute recently put forward a proposal for a $20/ton carbon tax that would rise 4 percent each year, starting in 2013. (The funds would be used to offset taxes elsewhere.) Here’s what their economic model predicts would happen to U.S. greenhouse-gas emissions:

Blue line: MIT reference case with no carbon tax. Black line: EIA reference. Green line: Scenario with MIT carbon tax in place.

With a carbon tax in place, U.S. greenhouse gas emissions do start declining quite a bit (this is the green line). But by 2030, emission levels stall, even though the carbon tax keeps rising and rising each year. The United States wouldn’t get anywhere near the 80 percent cut by 2050 that the White House has envisioned.

One explanation here is that MIT’s proposed carbon tax just isn’t high enough. But Muro favors another possibility–that a carbon tax alone isn’t enough to drive deep reductions. The private sector tends to under-invest in energy R&D and key bits of infrastructure such as transmission lines. Without further policies, it’s unlikely that we’ll see a sweeping transformation of our energy system to give people alternatives to coal plants and gasoline-powered cars.

This echoes an argument I've heard several times from those on the more technical side of climate change prevention. For all that the economists and politicians like to talk about creating the conditions in which the private sector will be incentivised to help tackle climate change, those who are more keenly aware of the massive costs involved tend to be rather more pessimistic.

They point out that the carbon tax model provides a cash injection to providers of low-carbon energy – but only after the tax is already instituted. As a result, there's another weak link in the chain, which is the ability of those providers to secure loans to build the capacity required. That's possible for massive companies looking to get into a new area; and it's possible for smaller companies, provided they get enough certainty from the government to be able to convince bankers.

But the fear is that larger companies, already strongly embedded in the conventional energy infrastructure, have little incentive to devote money, which could be used to lower the cost of polluting fuels, to instead build new capacity; and smaller companies won't be left with enough time between when the government finally confirms a carbon tax, and when their new generation is actually needed.

At the same time, though, there is growing evidence that some companies really are going above and beyond the call of duty. Some of it may be greenwashing, and some may be token expenditure, but if there really is any sizeable investment in low-carbon infrastructure, then it makes a carbon tax that much more effective.

Carbon taxes can only lower emissions if they raise the price of polluting relative to an alternative. If that alternative isn't available, then they risk being simply another source of revenue for the state.

What it’s like to fall victim to the Mail Online’s aggregation machine

I recently travelled to Iraq at my own expense to write a piece about war graves. Within five hours of the story's publication by the Times, huge chunks of it appeared on Mail Online – under someone else's byline.

I recently returned from a trip to Iraq, and wrote an article for the Times on the desecration of Commonwealth war cemeteries in the southern cities of Amara and Basra. It appeared in Monday’s paper, and began:

“‘Their name liveth for evermore’, the engraving reads, but the words ring hollow. The stone on which they appear lies shattered in a foreign field that should forever be England, but patently is anything but.”

By 6am, less than five hours after the Times put it online, a remarkably similar story had appeared on Mail Online, the world’s biggest and most successful English-language website with 200 million unique visitors a month.

It began: “Despite being etched with the immortal line: ‘Their name liveth for evermore’, the truth could not be further from the sentiment for the memorials in the Commonwealth War Cemetery in Amara.”

The article ran under the byline of someone called Euan McLelland, who describes himself on his personal website as a “driven, proactive and reliable multi-media reporter”. Alas, he was not driven or proactive enough to visit Iraq himself. His story was lifted straight from mine – every fact, every quote, every observation, the only significant difference being the introduction of a few errors and some lyrical flights of fancy. McLelland’s journalistic research extended to discovering the name of a Victoria Cross winner buried in one of the cemeteries – then getting it wrong.

Within the trade, lifting quotes and other material without proper acknowledgement is called plagiarism. In the wider world it is called theft. As a freelance, I had financed my trip to Iraq (though I should eventually recoup my expenses of nearly £1,000). I had arranged a guide and transport. I had expended considerable time and energy on the travel and research, and had taken the risk of visiting a notoriously unstable country. Yet McLelland had seen fit not only to filch my work but put his name on it. In doing so, he also precluded the possibility of me selling the story to any other publication.

I’m being unfair, of course. McLelland is merely a lackey. His job is to repackage and regurgitate. He has no time to do what proper journalists do – investigate, find things out, speak to real people, check facts. As the astute media blog SubScribe pointed out, on the same day that he “exposed” the state of Iraq’s cemeteries McLelland also wrote stories about the junior doctors’ strike, British special forces fighting Isis in Iraq, a policeman’s killer enjoying supervised outings from prison, methods of teaching children to read, the development of odourless garlic, a book by Lee Rigby’s mother serialised in the rival Mirror, and Michael Gove’s warning of an immigration free-for-all if Britain brexits. That’s some workload.

Last year James King published a damning insider’s account of working at Mail Online for the website Gawker. “I saw basic journalism standards and ethics casually and routinely ignored. I saw other publications’ work lifted wholesale. I watched editors...publish information they knew to be inaccurate,” he wrote. “The Mail’s editorial model depends on little more than dishonesty, theft of copyrighted material, and sensationalism so absurd that it crosses into fabrication.”

Mail Online strenuously denied the charges, but there is plenty of evidence to support them. In 2014, for example, it was famously forced to apologise to George Clooney for publishing what the actor described as a bogus, baseless and “premeditated lie” about his future mother-in-law opposing his marriage to Amal Alamuddin.

That same year it had to pay a “sizeable amount” to a freelance journalist named Jonathan Krohn for stealing his exclusive account in the Sunday Telegraph of being besieged with the Yazidis on northern Iraq’s Mount Sinjar by Islamic State fighters. It had to compensate another freelance, Ali Kefford, for ripping off her exclusive interview for the Mirror with Sarah West, the first female commander of a Navy warship.

Incensed by the theft of my own story, I emailed Martin Clarke, publisher of Mail Online, attaching an invoice for several hundred pounds. I heard nothing, so emailed McLelland to ask if he intended to pay me for using my work. Again I heard nothing, so I posted both emails on Facebook and Twitter.

I was astonished by the support I received, especially from my fellow journalists, some of them household names, including several victims of Mail Online themselves. They clearly loathed the website and the way it tarnishes and debases their profession. “Keep pestering and shaming them till you get a response,” one urged me. Take legal action, others exhorted me. “Could a groundswell from working journalists develop into a concerted effort to stop the theft?” SubScribe asked hopefully.

Then, as pressure from social media grew, Mail Online capitulated. Scott Langham, its deputy managing editor, emailed to say it would pay my invoice – but “with no admission of liability”. He even asked if it could keep the offending article up online, only with my byline instead of McLelland’s. I declined that generous offer and demanded its removal.

When I announced my little victory on Facebook some journalistic colleagues expressed disappointment, not satisfaction. They had hoped this would be a test case, they said. They wanted Mail Online’s brand of “journalism” exposed for what it is. “I was spoiling for a long war of attrition,” one well-known television correspondent lamented. Instead, they complained, a website widely seen as the model for future online journalism had simply bought off yet another of its victims.
