What Makes Greenhouse Sense? (Part 2/2) by Thomas C. Schelling From Foreign Affairs, May/June 2002
[FL: excerpts and commentary, highlighted as an aid to skimming]
Hot Air --------------- FL: Schelling briefly explains that emissions trading is a popular scheme and is part of the latest Nov. 2001 version of the protocol. Emissions trading allows nations that underuse their emissions quota to sell their excess rights to any other country. But he goes on to point out the inherent flaws in the system:
The problem with trading regimes is that initial quotas are negotiated to reflect what each nation can reasonably be expected to reduce. Any country that is tempted to sell part of an emissions quota will realize that the regime is continually subject to renegotiation, so selling any "excess" is tantamount to admitting it got a generous allotment the last time around. It then sets itself up for stiffer negotiation next time.
And in addition, since "excess quotas" or "hot air" as he calls it, have been awarded to several developing nations as inducement to sign the Protocol, both the credits selling and the credits buying nations have a cheap safety valve to their own commitments essentially skirting the spirit of the agreements. -----------
PAST AS PROLOGUE
There is remarkable consensus among economists that nations will not make sacrifices in the interest of global objectives unless they are bound by a regime that can impose penalties if they do not comply. Despite this consensus, however,there is no historical example of any regime that could impose effective penalties, at least with something of the magnitude of global warming. But there are historical precedents of regimes that lacked coercive authority but were still able to divide benefits and burdens of a magnitude perhaps comparable to the demands of a global-warming regime.
-------------- FL: The Marshall Plan (est. 1948) and NATO (est. 1951) serve as unusual precedents for coordinated global action. The aid varied from 5% to 20% depending on the nation. ----------
For the first two years of the Marshall Plan, the United States divided the money itself. For the third year, it insisted that the recipient countries divide the aid among themselves. Government representatives therefore went through a processof "reciprocal multilateral scrutiny." Each government prepared extensive documentation of all aspects of its economy:its projected private and public investments, consumption, imports, exports,what it was doing about railroads and livestock herds, how it was rationing gasoline or butter, and how its living standard compared to prewar conditions.Each government team was examined and cross-examined by other government teams; it then defended itself, revised its proposals, and cross-examined other teams. More aid for one country meantless for the rest.
There was no formula. Rather, each country developed "relevant criteria....Of course,the United States was demanding the countries reach agreement on aid. Today,there is no such "angel" behind green-house negotiations. Still, the Marshall Plan represents something of a precedent.
---------------- FL: Similarly, the NATO members engaged in a "burden-sharing exercise.
------------- ...it involved U.S. aid and included targets for national military participation, conscription of soldiers, investments in equipment, contributions to military infrastructure and real estate,and so on. Again, the process was one of reciprocal scrutiny and cross-examination,with high-level officials spending months negotiating...After one more year, NATO proceeded without U.S. aid—except for the contribution of U.S. military forces to NATO itself.
With the possible exception of the reciprocal-trade negotiations that ultimately created the World Trade Organization (WTO), the Marshall Plan and NATO experiences are the only non-wartime precedents in which so many countries cooperated over such high economic stakes. They were not aesthetically satisfying processes: no formulae were developed, just a civilized procedure of argument. Those examples are a model for what might succeed the Kyoto Protocol if it fails or evolves into something else. Their procedure is one that the main developed nations might pursue prior to any attempt to include developing nations. NATO has been an enormous success; member nations made large contributions in money,troops, and real estate. They did it all voluntarily; there were no penalties for shortfalls in performance.
--------- FL: Now a distinguishing feature becomes apparent: the difference between commitment to actions and commitment to results. ----------------
PROMISES, PROMISES
One striking contrast between NATO and the Kyoto Protocol deserves emphasis:the difference between "inputs" and "outputs," or actions and results. NATO nations argued about what they should do, and commitments were made to actions. What countries actually did—raise and train troops; procure equipment, ammunition, and supplies; and deploy these assets geographically—could be observed, estimated, and compared. But results—such as how much each NATO nation's actions contributed to deterring the Warsaw Pact—could not be remotely approximated.
With the Kyoto Protocol, commitments were made not to actions but to resuIts that were to be measured after a decade or more. This approach has disadvantages. An obvious one is that no one can tell, until close to the target date, which nations are on course to meet their goals.More important, nations undertaking result-based commitments are unlikely to have any reliable way of knowing what actions will be required — that is,what quantitative results will occur on what timetable for various policies....A government that commits to actions at least knows what it is committed to, and its partners also know and can observe compliance. In contrast, a government that commits to the consequences of various actions on emissions can only hope that its estimates, or guesses, are on target, and so can its partners.
-------------------- FL: Schelling concludes that the wealthy nations will have to carry the water for a while. In particular, we need to fund serious research efforts to replace fossil fuels over the coming decades. The developing nations are depending on us, and others, to shoulder these responsibilities. ---------------------
SPREADING THE WEALTH
Eventually, to bring in the developing nations and achieve emissions reductions most economically, the proper approach is not a trading system but financial contributions from the rich countries to an institution that would help financ eenergy-efficient and decarbonized technologies in the developing world.....
Such a regime will suffer the appearance of "foreign aid." But that is the form it will necessarily take. The recipients will benefit and should be required to assume commitments to emissions-reducing actions. Meanwhile, the burden on the rich countries will undoubtedly be more political than economic. Large-scale aid for reducing carbon dioxide emissions in China is economically bearable but enormously difficult to justify to the American public, or to agree on with Japan and the European Union.
While European countries are lamenting the U.S. defection from theKyoto Protocol, a major U.S. unilateral initiative in research and development oriented toward phasing out fossil fuels over the next century would both produce welcome returns and display American seriousness about global warming.
The greenhouse gas issue will persist through the entire century and beyond.Even though the developed nations have not succeeded in finding a collaborative way to approach the issue, it is still early.We have been at it for only a decade. But time should not be wasted gettingstarted. Global climate change may become what nuclear arms control was for the past half century. It took more than a decade to develop a concept of arms control. It is not surprising that it is taking that long time to find a way to come to consensus on an approach to the greenhouse problem. |
