A steady state economy

Cup with a nose and lips on it

One key tenet of ecological economics is that we need to move from a political and economic system focused on the growth of production (GDP) to one focused on constant biophysical throughput. The latter concept is basically an amalgamation of everything humanity takes from the physical world and all the wastes that are returned to it. On the first side of the ledger are withdrawals like ore and hydrocarbons; on the other are wastes including greenhouse gasses and other forms of pollution. While it could not be expressed in the form of a single number, it is fairly easy to imagine a suite of key physical and energy flows through which the aggregate size of human throughput could be summarized.

The basic idea has appeal for several reasons. Most obviously, it addresses the concerns that exist about how much impact humanity can have on the world without causing key biological and physical systems to fail. It also partially addresses the question of how to ensure that human lives become sustainable without becoming unnecessarily unpleasant. It’s the human throughput that actually weighs on the world, not GDP. Even in a situation where the throughput was constant, welfare per person could still increase in many ways: things could become more technologically advanced, better designed, more elegant, etc. They could also be improved significantly by more effectively eliminating situations of needless suffering, as with the treatable diseases that continue to take a terrible toll in the developing world. Of course, per-capita improvements could also be achieved with constant throughput and a falling population.

One objection to the idea is that, when it comes to renewable power, we are nowhere near the physical limits of what is possible. The total quantity of solar, wind, and tidal energy available is momentous, and it doesn’t seem sensible to focus on the total size of human withdrawals from those flows. As such, perhaps the steady-state approach is better suited to non-energy resources, while on the topic of energy, the drive must be from unsustainable forms (oil, gas, coal) to semi-sustainable forms (nuclear fission, etc) and eventually to fully sustainable options like concentrating solar thermal, hydroelectric, and geothermal.

In the end, the prescription for humanity seems to resemble a cheesy grocery store magazine diet: avoid carbon-intensive fuels, manage resource use and waste flows, and feel free to use all the renewable energy and carbon- and resource-neutral technological advancement as you can manage.

U.S. Submission on Copenhagen Agreed Outcome

Dog chain

In preparation for the upcoming UNFCCC meeting in Copenhagen, various parties to the agreement have made submissions, outlining their perspectives on the negotiations. The position of the United States (PDF) is now available.

I don’t personally have time to keep track of the details of all the various proposals. Furthermore, the alliances formed between negotiating parties may prove to be the most important element in determining the outcome of the meeting. Nonetheless, I thought it would be of interest.

Australia’s carbon price delayed

When Australian Prime Minister Kevin Rudd came to power, it was hailed as a victory against climate change, given the inaction of his predecessor and the contents of the Rudd platform. Disappointingly, a key element of that has how been put on hold for a year, supposedly because of the ongoing economic crisis. Australia’s emissions trading scheme (ETS) will now launch in 2011, rather than July 2010, as originally planned.

Personally, I think it is foolish to delay carbon pricing on account of the credit crunch. We want to be rebuilding national economies in a manner complimentary to climatic stability. Also, the less time we give ourselves to increase carbon prices to the necessary levels, the more painful the eventual adjustment will be. Given that prices were to be set at $7 per tonne for the first year, the policy would not have been an excessive burden on industry, even if the funds weren’t recycled back via tax cuts elsewhere or investments in low-carbon infrastructure. A moderate carbon price now thus serves the dual purpose of alignment economic redevelopment more with environmental goals, while stretching out the total timeline across which adjustments will be made.

Like Canada, Australia has some of the highest per-capita emissions in the world. That means they bear special historical responsibility for the climate change problem. It also means they should have more opportunities for low-cost reductions in emissions. Both ethical and economic logic suggest that this delay is a mistake.

The Global Climate Coalition and climate change denial

Kid with a fake nose and glasses

Some interesting evidence has emerged about the artificial ‘debate’ that has been created about the reality of human-induced climate change. Documents filed in a federal lawsuit reveal that the scientists working for the Global Climate Coalition – a fossil fuel industry front group that sought to prevent action on climate change – were themselves convinced of the reality of the problem. Back in 1995, they advised in an internal paper that: “The scientific basis for the Greenhouse Effect and the potential impact of human emissions of greenhouse gases such as CO2 on climate is well established and cannot be denied.”

This contrasts sharply with what the group said in public, and what they probably said to politicians while lobbying. It helps to demonstrate that the tactic here isn’t appropriate scientific skepticism, but simply a rearguard action to delay climate change mitigation policies. They have certainly succeeded in confusing some politicians with an ideological bent that predisposes them to rejecting climate policies. For instance, Republican Representative for Minesota Michele Bachmann has publicly expressed an absurd position on the science of climate change, while also calling for those who are opposed to climate legislation to be “armed and dangerous” and ready to “fight back hard” against legislation like the Waxman-Markey bill.

Who would control geoengineering?

Sasha Ilnyckyj's eyes

Over at Slate there is an interesting article about the geopolitics of geoengineering: specifically, the ramifications of the fact that any major nation could choose to deliberately modify the planet’s climate. As the author identifies, this is in some sense the reverse of the ordinary climate change problem. So far, the issue has been how to produce a global action when states disagree on what should be done, how quickly it should occur, and who should pay. By contrast, the problems with the politics of geoengineering are making sure that any states that undertake it do so with the interests of all states (and future generations) in mind.

This is especially problematic because the side-effects of geoengineering might fall disproportionately on certain states, probably the ones who would not be in control of the policy. For instance, consider the so-called ‘Pinatubo option’ of particulate injection into the upper atmosphere. It might help cool the planet overall, but could severely disrupt patterns of precipitation and wind. It would also do nothing about the problem of ocean acidification. Who would decide if the possible advantages outweighed the risks? Who would pay for the side effects? Who could decide to shut the system down, if the effects in some places prove too painful?

Another issue with the ‘Pinatubo option’ is that it would need to be constantly maintained to keep working. This could be an advantage, since we could ‘turn it off’ if it proved too problematic. It could also be a disadvantage, since disabling the system would bring about abrupt and dangerous warming.

All this may be moot, if no forms of geoengineering actually work, or if the danger of unintended consequences is sufficient to deter states from trying. That being said, I see geoengineering (regrettably) as a real possibility. If we don’t reduce emissions fast enough and start to really feel the full brunt of climate change, it will become harder and harder to argue against. As such, it is good that we are starting to consider both the physical and political elements of geoengineering now.

A Canadian coal phase-out

Both The Globe and Mail and The New York Times are reporting on recent comments from Jim Prentice, Canada’s minister of the environment, about phasing out coal-fired electricity in Canada:

“The concept is that, as these facilities are fully amortized and their useful life fully expended, they would not be replaced with coal.”

That is certainly necessary, but may not be sufficient to achieve Canada’s domestic emission reduction targets. Indeed, if the world as a whole is to get onto an emissions path consistent with avoiding dangerous climate change, it will probably be necessary to scrap some existing coal plants before the end of their working lives.

About 18% of Canada’s current greenhouse gas emissions are from coal-fired electricity, with facilities in Ontario (about 25% of the total), Alberta (about 47%), Saskatchewan, Nova Scotia, and New Brunswick.

Limiting total historical human emissions

Osterer's sign

The BBC recently published an article that goes together well with two of my earlier posts. Like my post on how many greenhouse gasses humanity can safely emit and my post on the (absent) long-term future of the fossil fuel industry, it highlights how preventing catastrophic climate change obliges humanity to keep a significant proportion of all available fossil fuels in the ground. The BBC piece cites an article in Nature which argues that we must leave 75% of the remaining fossil fuels untouched, if we are to avoid dangerous climate change.

What this highlights is how the world has two great stocks of carbon, between which humanity is generating an ever-increasing flow: (a) the stock of fossil fuels, containing carbon dioxide that hasn’t been in the atmosphere since the Eocene period 30 – 50 million years ago, and (b) the stock of carbon dioxide currently in the atmosphere, trapping ever-more energy from the sun. If we are to live in a world without massive disorder, displacement, and upheaval by the end of the century, we need to start closing the spigot from (a) to (b), even though it will mean leaving a lot of usable fuel underground.

That will take more restraint than humanity has been able to muster for any collective project so far.

Transnational activism and the 2005 Gleneagles summit

Claire Leigh, a friend of mine and colleague from the Oxford M.Phil program, has published an article based on her thesis in Cosmopolis: Independence and transnational activism: lessons from Gleneagles. It may be of particular interest to the many readers of this blog who are interested in effecting political change through civil society, protest, and mass action.

The full text doesn’t seem to be available on the site, but those whose universities have print or electronic subscriptions to journals may be able to access it.

Climate risk ‘pyramid’ from US polling data

Graffiti murals in the ROM

Back during the 2008 election, many eyes were glued to fivethirtyeight.com: the statistics-oriented website of a baseball analyst turned electoral statistician. A couple of days ago, the man who runs the site posted an interesting diagram based on polling data about climate change (n=2,164). Basically, it shows that ever-decreasing numbers of people expect harm from climate change, the closer to them it would appear. For instance, more people expect it to harm plants and animals than people, and more people expect it to harm those in developing countries than those in the US.

All told, I think the trend is an accurate reflection of the most likely outcomes from climate change. It seems highly likely, for instance, that future generations will suffer more than this one. Nonetheless, the chart does a good job of demonstrating just how hard it is to get people to accept immediate sacrifices in order to protect long-term climate stability: they are not fully exposed to the risks, and they have ample opportunity to fob them off on others, so as to avoid making changes in how they live their own lives and how the political and economic systems in their states operate.

While I think the pyramid is basically correct when it comes to the relative magnitude of harm that will likely occur in each area, what it doesn’t convey is that the absolute level of harm would still be unacceptable, across the board, in the absence of strong climate policies. Continuing to emit greenhouse gasses at present levels until the end of the century will almost certainly cause massive harm to those living in the United States and other rich countries. It may not be as bad as the harm that would be visited on future generations and poorer countries, but it is more than serious enough to justify devoting a significant fraction of society’s resources to building a carbon neutral future.

There is some more discussion of the pyramid over at ZeroCarbonCanada.

Emissions permits for new entrants

One proposed element for a cap-and-trade system is holding back some permits for ‘new entrants.’ Basically, this would mean preemptively grandfathering emissions from certain types of new facilities. Depending on how it was done, it seems like it could be either environmentally beneficial or harmful. If the overall cap for any year is set below the level of emissions last year, on a downward trajectory compatible with stabilizing concentrations at a safe level, reserving some credits for new entrants would force other firms to bid for fewer permits, raising prices and increasing the number of mitigation activities that are worth undertaking. Conversely, if this is used as an excuse to increase the cap, it might impede the transition to a low-carbon future.

There is also the issue of complexity. It seems likely that special treatment for new entrants will lead to weird Enron-style accounting trickery. The more complicated a carbon pricing scheme becomes, the easier it is to do hidden favours, and the harder it is to transparently assess what is going on.
