Who’s “Out of Step” on Climate — Pope Francis or Harvard Expert?

New York Times climate reporter Coral Davenport writes today that Pope Francis’s warning against cap-and-trade as a tool to address the climate crisis creates a “paradox”:

[W]here Francis’ environmental and economic agendas meet, he leaves something of a paradox. . . While urging swift action to curb the burning of fossil fuels that have powered economies since the Industrial Revolution, he also condemns the trading of carbon-emission credits, saying it merely creates new forms of financial speculation and does not bring about “radical change.” But carbon trading is the policy most widely adopted by governments to combat climate change, and it has been endorsed by leading economists as a way to cut carbon pollution while sustaining economic growth.

With due respect to Davenport as well as Robert Stavins, the Harvard climate economist whose concerns figure prominently in her story, there is no paradox. Francis’s encyclical, On Care For Our Common Home, doesn’t muddy the climate change debate because a carbon tax, not cap-and-trade, is economists’ preferred policy tool for curbing carbon pollution. Francis-cap-tradeFrancis criticizes emissions trading on three grounds: First, trading carbon allowances allows traders to profit from the climate crisis — indeed, it’s designed to do that. Second, “offsets” that are virtually hard-wired into cap-and-trade shift the burden of pollution to developing countries. Third, cap-and-trade with offsets absolves the wealthy of responsibility to rein in their carbon-intensive lifestyles. In Francis’s own words:

The strategy of buying and selling carbon credits can lead to a new form of speculation which would not help reduce the emission of polluting gases worldwide. This system seems to provide a quick and easy solution under the guise of a certain commitment to the environment, but in no way does it allow for the radical change which present circumstances require. Rather, it may simply become a ploy which permits maintaining the excessive consumption of some countries and sectors. [171]

What, then, does Francis demand? That societies internalize the costs of pollution, especially climate pollution:

[O]nly when the economic and social costs of using up shared environmental resources are recognized with transparency and fully borne by those who incur them, not by other peoples or future generations, can those actions be considered ethical. [195]

A reference in that passage attributes Francis’s calls for polluters to pay “the economic and social costs” they incur to his predecessor, Pope Benedict. (Both pontiffs presumably intended “impose” rather than “incur,” i.e., for costs to be borne by those who impose them, but no matter.) Those resources surely include clean air. The new encyclical thus aligns the Catholic Church with the century-old “Pigovian” tradition of economists urging policies to internalize costs. Francis-carbon4-taxNevertheless, in an email quoted by Davenport, Stavins brands Francis as “out of step with … informed policy analysts around the world,” in effect labeling the Pope as economically-illiterate and naïve:

“I respect what the pope says about the need for action, but this is out of step with the thinking and the work of informed policy analysts around the world, who recognize that we can do more, faster, and better with the use of market-based policy instruments — carbon taxes and/or cap-and-trade systems,” Robert N. Stavins, the director of the environmental economics program at Harvard, said in an email.

That Stavins is the lone environmental economist quoted in Davenport’s piece did not deter her from claiming that “environmental economists criticized the encyclical’s condemnation of carbon trading, seeing it as part of a radical critique of market economies.” Hardly. The Pope, like legions of environmental activists and economists worldwide, has seen the shams of emissions trading and carbon “speculation” for what they are. [Read more…]

Earth Institute Chief Trashes the Carbon Tax

Steven Cohen, executive director of Columbia University’s prestigious Earth Institute, recently weighed in on the carbon-tax debate in the Huffington Post. The results are breathtaking – and not in a good way.

Cohen’s June 8 screed, “A Carbon Tax Is Not Feasible or Practical,” was a riposte to a New York Times editorial two days earlier endorsing a carbon tax as “one of the best policies available” to address global warming. The Times is wrong, says Cohen, as he proceeds to lay out a multi-count indictment. Among his anti-CT arguments are the following:

1. Carbon taxes are politically infeasible: Given the system’s deep hostility to tax hikes, “the space between the carbon tax as a policy idea and the reality of American politics is too vast to overcome. For better or worse, here in America we are in a period of tax policy paralysis that is unlikely to be surmounted anytime soon.”

2. Carbon taxes are unfair: They “cause people on the lower end of the economic ladder to pay a higher portion of their income on energy,” while corrective measures aimed at redistributing the costs “are far from simple to implement, might stigmatize recipients, and would become easy and obvious political targets.”

3. Contrary to The Times, carbon taxes are unequal to the problem of climate change because they would founder on the shoals of international politics: “China and India would need to go along, and given the urgency of their energy and development needs, it is difficult to imagine that they would agree to such a measure.”

4. Carbon taxes are anti-urban: “I sometimes think the push for a carbon tax comes out of an early 20th century environmentalist mindset that scolds people for consumption and living in evil, immoral cities.”

5. Finally, carbon taxes are unnecessary since tax breaks can be just as easily used to encourage alternative energy development: “Why waste time and effort on an infeasible policy that will never happen? Why not devote time and effort to building a real partnership between the public and private sector to create a sustainable economy?”

NYT-CohenCareful readers will notice that the first two items are variations on a theme, which is to say the futility of relying on the U.S. political system to pass a well-crafted carbon-tax plan that discourages fossil fuels without burdening workers and the poor. The same can be said for number three, which is about the inability of a beggar-thy-neighbor international system to institute significant reform. Whether the fault lies with Washington, Beijing, or New Delhi, Cohen argues, the point remains that politicians of all nationalities are too selfish and shortsighted to deal intelligently with a carbon tax, so it’s best to forget the whole thing.

Charges four and five are different, so let’s tackle those first. [Read more…]

Don’t Anchor a Carbon Tax to the Social Cost of Carbon

Editor’s note: Yesterday the world’s most influential newspaper finally did what CTC and other carbon tax proponents have sought for years: publish a ringing endorsement of a U.S. carbon tax. With its editorial, The Case for a Carbon Tax, the New York Times joins the growing community of opinion leaders, policy experts and, yes, elected officials who not only recognize the power of carbon taxes to quickly and equitably reduce emissions but also sense the emergence of a political critical mass that can enact fees into law. This heartening development signals that it’s not too soon to focus on the design of a U.S. carbon tax, especially its magnitude and rate of increase, as CTC senior policy analyst James Handley does in this post.

Which is the more effective way to set a tax on carbon pollution?

A. Start aggressively, then raise the rate slowly (“sprint”).

B. Start modestly, then raise the rate briskly and predictably (“marathon”).

You probably guessed that if the goal is to instill incentives that will bring about big emission reductions fast enough to avoid runaway global warming, the answer is B, the marathon. Yet a leading U.S. Senate advocate of legislative action on climate seems to be starting off like a sprinter, perhaps because his legislation is pegged to estimates of the Social Cost of Carbon that don’t account for the possibility that climate change will turn out to be catastrophically costly.

More on that senator in a moment — after this tutorial:

The Social Cost of Carbon (SCC) is a construct to quantify in monetary terms the damage caused by each additional ton of CO2 added to the atmosphere. While the SCC may sound arcane or academic, estimating its magnitude has real world implications: governments are pegging climate-related regulatory decisions to SCC estimates. A low SCC can make all but the lowest-cost clean-energy policies pencil out as expensive; higher estimates justify more rapid and aggressive measures, since moving too slowly to reduce emissions shows up as a mistake whose costs accumulate at a frightening pace.

Calculating the damage from a ton of CO2 turns on a host of assumptions that span wide ranges. Not surprisingly, estimates of the SCC reported in the peer-reviewed economics literature range from as little as $10 per ton of CO2 to over $400. A profoundly important modeling choice is how heavily to weigh the risks of climate-induced catastrophes. High-risk climate scenarios with nearly infinite costs, such as rapid release of methane from arctic permafrost or sudden sliding of vast ice masses into the ocean, “misbehave” in the equations used for conventional cost-benefit analysis, leading some modelers to omit them altogether.

One widely-used model assumes that economic growth rates will not be affected by climate change, thereby predicting that half of the world’s economic activity would continue after a whopping 18 degrees C of global warming. Other models dilute the high-risk scenarios by assigning them arbitrarily low probabilities that suppress their impact when their costs are averaged in with low-risk scenarios. A further problem in estimating the SCC is the bias toward high “discount rates” that telescope future impacts down to seemingly manageable proportions.

Amidst fraught debate and widely-divergent estimates, the Interagency Working Group has settled on $42 per ton of CO2 as the “official” U.S. government social cost of carbon. While that’s an improvement over past practice that omitted climate costs entirely — tacitly, an SCC equal to zero — the $42 figure grossly understates the large-scale global risks that dominate concern over global warming and climate change.

Book Review: “Climate Shock”

Rachael Sotos is a political theorist and adjunct professor with a background in philosophy, classics and environmental studies.

Climate Shock: The Economic Consequences of a Hotter Planet, is both a tidy summation of the state of the art in climate economics and a powerful call for action. For all the uncertainties and challenges, “the overall policy framework needed for addressing climate change is clear and has been for decades,” state co-authors Gernot Wagner and Martin L. Weitzman (p. 23). “Carbon dioxide is the problem. Pricing it properly is the solution.”(38)

climate shock coverWagner, a senior economist at the Environmental Defense Fund, and Weitzman, a celebrated economist at Harvard, are an intriguing blend of young and elder, and realist and idealist. They exhort economists and climate advocates to get past the “epic debates” between taxes and cap-and-trade and, while consensus builds toward carbon pricing, to engage in the work required for “second -, third-, and fourth-best solutions”(26): electricity grid reform, stronger CAFE standards, and strategic application of subsidies and U.S. EPA regulations. “At the very least,” they say, “these regulations could provide a real bargaining chip when it comes to U.S. Congress considering comprehensive climate policy and a direct price on carbon down the line.”(19).

Flying their Pigovian colors from Preface to Epilogue, the authors are emphatic and unambiguous; “Putting a proper price on carbon isn’t a question of if, it’s a question of when.(xi) Our best hope is “a high enough price on carbon to reflect its true cost to society.”(152)

Unfortunately, the bracing clarity of Climate Shock appears to have been lost on some reviewers. Earlier this month, NY Times columnist Joe Nocera misconstrued Wagner and Weitzman’s extensive discussion of geo-engineering as surrender to the political obstacles to carbon pricing. On Nocera’s reading, insofar as “a carbon tax on the worst emitters has gotten nowhere,” it’s time for Plan B: “chemo for the planet.” Au contraire, Wagner and Weitzman do not delve into geo-engineering scenarios like sulfates dispersal in lieu of ambitious policies to reduce emissions. Rather, they insist, “the specter of geo-engineering should be a clarion call for action. Decisive, and soon.”(29)

If Nocera reconfigured Wagner and Weitzman to suit his own techno-utopian ends, Yale Nobel economist Robert J. Shiller, also in the Times, willfully invested Climate Shock with libertarian designs. Directly contravening the thoughtful and informative discussion of social change presented in Climate Shock (and previously thematized in Wagner’s 2011 But Will the Planet Notice?), Shiller proposed idealistically-motivated incrementalism as a way around Kyoto’s failure “to impose strict taxes on carbon emissions.”

According to Shiller, Wagner and Weitzman “say that we should be asking people to save our climate by taking many small, individual actions.” Climate Shock actually says the opposite: “the numbers don’t add up. They’ll only begin to add up when environmentalists use their collective political powers to move the policy needle in the right direction, toward a price on carbon.”(40) (See also CTC director Charles Komanoff’s recent takedown of Shiller’s piece in regard to both facts and theory.)

Shiller’s misreading is doubly unfortunate because, as Wagner and Weitzman point out, the imperative to seriously engage policy must be directed toward average citizens, “those in the middle of the political spectrum,” as well as those already conversant with climate economics.(136) Certainly we should all do what we can to encourage virtuous cycles of ethical engagement and political participation – “Recycling well leads to better environmental policies, which allow for a more environmentally enlightened citizenry; a more enlightened citizenry, in turn, leads to more people recycling well.”(132)

Indeed. But, as Wagner and Weitzman are right to remind: in a greenwashed world seemingly structured to distract and misinform the average person, the most virtuous deeds can dead end. In the practical economics of everyday life, single actions sometimes crowd out other forms of engagement: “when people substitute single, individual actions – like recycling – for larger policy actions – like voting.”(133) Pigovians from start to finish, Wagner and Weitzman are emphatic: “if you have to make a choice between recycling and voting for a price on carbon, choose voting.”(137)

Yet another review, this one by Yale economist William D. Nordhaus in the current New York Review of Books, is notable on several grounds, not least of which is Nordhaus’s outsized reputation as a pioneering climate economist and modeler. Respectful in tone, Nordhaus engages of Climate Shock’s discussions of geo-engineering, the economics of uncertainty and the pitfalls of negotiating climate treaties. Strangely, however, Nordhaus takes up Weitzman’s path-breaking analyses of catastrophic risk without acknowledging any critiques of his own perennially optimistic approach.

A Carbon Tax Can Carry Earth Day’s Legacy

In 1970 I was teaching math in a New York City suburb. On Earth Day I stood at a highway off-ramp with members of the high school ecology club. One of their signs read, “The Earth is a Closed Garage.” Another said, “Make Polluters Pay.”

There’s been some progress since then. Breathing New York’s air, once equated to smoking two packs of cigarettes a day, is many times safer. Wind turbines now provide five percent of the nation’s power, and electricity produced with solar cells rose ten-fold in the past three years. Driving has flatlined nationwide over the past decade, partly because Americans are strapped but also because the intoxication with cars is wearing off.

That’s great news for the environment, but it’s not nearly enough for climate. CO2 levels are still rising inexorably. Ditto global temperatures, polar ice melting and extreme weather. Emissions need to be cut radically even as seven-and-a-half billion people strive for prosperity.

For that to happen, prices of fossil fuels have to reflect the climate costs of carbon pollution. The way to do this, of course, is with carbon taxes:

To demystify carbon taxes and showcase their appeal, we’re rolling out the Carbon Tax Center’s first video. It explains how a carbon tax will transform investment, re-shape consumption and sharply reduce carbon emissions. As the video shows, no other policy can match its reach or simplicity. No other policy can be replicated globally, from China to Chile to Chad.

A carbon tax is no mere “technical fix.” It’s both a symbol and a means for us to respect nature and each other.

The central messages on Earth Day 1970 were to abide by nature’s limits and make polluters pay. On this Earth Day, let’s spread the word about a carbon tax. Let’s educate and organize so that the U.S. and other nations make taxing carbon the central policy to combat catastrophic climate change and sustain the Earth we love.

Climate Idealism Can’t Hold a Candle to Collective Action

Why do Copenhageners ride bicycles? The key reason, says Yale economist and best-selling author (“Irrational Exuberance”) Robert J. Shiller, is that Danes are idealists who resolved, after the oil crisis of the 1970s, “to make a personal commitment to ride bicycles rather than drive, out of moral principle, even if that was inconvenient for them.”

“The sight of so many others riding bikes motivated the city’s inhabitants and appears to have improved the moral atmosphere enough,” Shiller wrote in yesterday’s New York Times, that the share of working inhabitants of Copenhagen who bike has reached 50 percent.

From “Copenhagen: City of Cyclists” (2010), a report by the City of Copenhagen.

From “Copenhagen: City of Cyclists” (2010), a report by the City of Copenhagen.

In much the same way, Shiller argues, “asking people to volunteer to save our climate by taking many small, individual actions” may be a more effective way to bring down carbon emissions than trying to enact overarching national or global policies such as carbon emission caps or taxes.

Goodness. Rarely do smart people so badly mangle both the historical record and basic economics. I say “people” because Shiller attributes his column’s main points to a new book, “Climate Shock: The Economic Consequences of a Hotter Planet” by Gernot Wagner of the Environmental Defense Fund and Martin L. Weitzman, a Harvard economist. And I say “smart” because the three stand at the top of their profession. Shiller won the Economics Nobel in 2013, Weitzman is a leading light in the economics of climate change, and Wagner is highly regarded young economist.

But mangle they have (I haven’t seen the Wagner-Weitzman book but assume that Shiller represents it fairly).

Let’s start with the history, which is fairly well known to anyone versed in cycling advocacy, as I’ve been since the 1980s, when I spearheaded the revival of New York City’s bike-advocacy group Transportation Alternatives (as recounted here.) Copenhagen’s 40-year bicycle upsurge, and indeed much of the uptake of cycling across Denmark, Germany and the Netherlands, came about not through mass idealism but from deliberate public policies to help cities avoid the damages of pervasive automobile use while reducing oil dependence.

If idealism played a part at the outset it was a social idealism that instructed government to undertake integrated policies ­― stiff gas taxes and car ownership fees; generously funded public transit; elimination of free curbside parking; provision of safe and abundant bicycle routes ― that enabled Copenhageners to do what they evidently desired all along: to use bikes safely and naturally.

The telltale is in the graphic. Only one in eleven Copenhageners who cycle have environment and climate in mind. The majority do it because it’s faster than other ways to travel, and around a third of cyclists say they ride because it’s healthy, inexpensive and convenient ― belying Shiller’s meme of Danes idealistically choosing bikes despite their inconvenience vis-à-vis cars.

One Cheer for the Guardian’s Divestment Campaign

The worldwide fossil fuel divestment campaign got a huge boost this week when Guardian editor Alan Rusbridger boldly thrust his paper into the fray. Britain’s most respected newspaper is urging readers to sign a petition by 350.org demanding that the Gates Foundation and the Wellcome Charitable Trust divest from the world’s top 200 fossil fuel companies within five years.

Divestment can’t loosen the fossil fuel stranglehold without a carbon tax.

Combined, the two charities manage over $70 billion in assets. Both say they consider climate change a  serious threat. But last year the Gates Foundation invested at least $1 billion of its holdings in 35 of the top 200 carbon reserve companies, while the Wellcome Trust invested $834 million in fuel-industry mainstays Shell, BP, Schlumberger, Rio Tinto and BHP Billiton.

We’re both elated and concerned by Rusbridger’s audacious move. Elated that this distinguished and brave journalist has thrown down the gauntlet to the global fossil fuel industry. But concerned that this divestment campaign may raise false hopes.

As Matthew Yglesias articulated last year in a thoughtful piece on Slate, divestment by socially responsible investors, universities and even governments won’t starve capital flows to fossil fuel corporations anytime soon. That’s because in a global market, every share of stock we activists dutifully unload will be snatched up in milliseconds by some trader who can bank on humanity’s continued dependence on fossil fuels to continue generating profits.

South Africa’s historic divestment campaign — the one that helped topple Apartheid and enshrined divestment as a tool against oppression  — was paired with a UN-sponsored boycott of South African goods. Not just aiming at the supply of capital but destroying the demand for goods sheared the Apartheid regime’s economic lifeline to the rest of the world more than either policy could have done alone.

No, we’re not suggesting a global boycott of fossil fuels. Rather, we point to the Guardian’s campaign to reiterate that the best and maybe only broadly effective way to reduce fossil fuel demand (which is the point of a boycott) is with a carbon tax. Economists agree on that policy prescription just as strongly as climate scientists agree on the diagnosis. And national-level carbon taxes can be designed to draw our or any nation’s global trading partners into carbon taxing, which means that a move by a big economy to impose a carbon tax will trigger a wave of followers.

So by all means, divest. The cultural and perhaps political opprobrium that divestment can spark is long overdue for the fossil fuels industry. But let’s not assume that divestment alone will break the chains of fossil fuel dependence. Even with the Guardian’s welcome campaign, the world still needs a transparent price on carbon pollution to strangle demand for fossil fuels by replacing them with non-carbon alternatives.

British Columbia’s Carbon Tax Architects Speak

A new report from a British Columbia think tank reveals the inside story behind B.C.’s successful tax on CO2 pollution. “How to Adopt a Winning Carbon Price, Top Ten Takeaways from Interviews with the Architects of British Columbia’s Carbon Tax,” published by Clean Energy Canada, draws on extensive interviews with senior government officials, elected representatives and a broad range of experts who helped shape or respond to this groundbreaking policy.

BC C-TX RPT CVRBritish Columbia inaugurated its carbon tax on July 1, 2008 at a rate of $10 (Canadian) per metric ton (“tonne”) of carbon dioxide released from coal, oil and natural gas burned in the province. The tax incremented by $5/tonne annually, reaching its current level of $30 per tonne of CO2 in July 2012. At the current U.S.-Canadian dollar exchange rate (1.00/0.80), and converting from tonnes to short tons, the B.C. tax now equates to around $22 (U.S.) per ton of CO2.

In the tax’s initial four years (2008 to 2012), CO2 emissions from fuel combustion in British Columbia fell 5% — or 9% per capita, considering the province’s 4.5% population growth over that span. [NB: These figures are revised downward from the original version of this post; see editor’s note at end.] During the same period, emissions from the rest of Canada increased slightly. Revenue from the tax has funded more than a billion dollars worth of cuts in individual and business taxes annually, while a tax credit protects low-income households who might not benefit from the tax cuts.

Why is Naomi Klein So Cool on a Carbon Tax?

(Daniel Lazare is a writer living in New York City; his books include The Frozen Republic, The Velvet Coup, and America’s Undeclared War.)

Naomi Klein is not exactly bubbling over with enthusiasm about a carbon tax, and since she has emerged as a leading voice on climate change, it’s worth exploring why. She barely mentions the topic in This Changes Everything: Capitalism vs. The Climate, her magnum opus on global warming, and was oddly dismissive in a recent interview with Grist. “I don’t think a carbon tax is a silver bullet,” she said, “but I think a progressively designed carbon tax is part of a slate of policies that we need to make this transition … [to] rapid renewables.” But then she went on to disparage the analysis that is at the core of the carbon-tax argument:

You know, I’ve been making these arguments around economics, but there is nothing more powerful than a values-based argument. We’re not going to win this as bean counters. We can’t beat the bean counters at their own game. We’re going to win this because this is an issue of values, human rights, right and wrong. We just have this brief period where we also have to have some nice stats that we can wield, but we shouldn’t lose sight of the fact that what actually moves people’s hearts are the arguments based on the value of life.

So on one hand we have economics, the stuff of “bean counters” and other bloodless sorts, while on the other we have values and morality. A carbon tax would be beneficial, but since we will never beat the economic analysts on their own turf, there’s no point even trying. Instead, we should concentrate on things that stir the soul, such as human rights.

Naomi Klein: Why is she so cool on taxing carbon pollution?

Naomi Klein: Why is she so cool on taxing carbon pollution?

Or so Klein maintains. But there’s something off-putting about such arguments. The distinction between economic analysis and morality, for instance, smacks of anti-intellectualism. Not only are head and heart separate and distinct in Klein’s world, but there’s no question as to which is on top. But her view of a carbon tax is also incorrect. It’s not for bean counters only. Like any real-world phenomenon, a carbon tax is multi-dimensional, which means that it has not only an economic component but a political and moral aspect as well.

How so? Everyone knows what the purpose of a carbon tax is. It’s to internalize the externalities, to take the growing costs associated with fossil fuels and bundle them into the price of such fuels so that the individuals using them have a more accurate idea of how much a specific activity truly costs. When drivers understand how expensive gasoline really is when all the attendant costs are taken into account, then they’ll treat it with the respect it deserves.

This is the sort of economic wonkery that no doubt leaves Klein cold. But it is not only an economic argument. Externalities include not only environmental and congestion costs and the like, but such items as the cost of insuring an uninterrupted flow of oil from the Persian Gulf. Expenditures like these aren’t trivial, needless to say. Indeed, one study published in Energy Policy puts them at a stunning $7 trillion for the years 1976-2007, not including the Iraq War, which, according to Joseph Stiglitz and Linda Bilmes, may wind up costing $3 trillion more.

Conservatives: Unpriced Carbon Pollution is Theft — Milton Friedman Would Tax It

Free dumping of CO2 pollution into the atmosphere is nothing less than “theft” from future generations who stand to suffer from unabated global warming, declared University of Chicago economist Steve Cicala at a symposium last week in honor of the conservative icon Milton Friedman. “It is theft,” said Cicala. “That’s a loaded term, but if someone else has a better term for taking something from someone without their consent and without compensating them, I’d be happy to hear it.”

E&E News reports that Cicala and former Obama White House adviser Michael Greenstone, who holds the Friedman chair at the U. of Chicago and directs its Energy Policy Institute, asserted that “if the late free-market economist Milton Friedman were alive today, he’d probably support pricing carbon.”

According to E&E, Cicala and Greenstone argued that,

Friedman… would have viewed climate change as a negative externality associated with burning fossil fuels and would have believed that society was entitled to recover its losses from those who emit carbon to advance their economic interests… While there is a market for the products that are associated with greenhouse gas emissions — like electricity, fuel and steel — there is no market for the pollution inflicted by their manufacturers on the public.
