  1. Trade, Growth,and the Environment Jeffrey Frankel Harpel Professor Graduate Consortium on Energy and Environment 24 Oxford Street, 3rd Floor, noon-1:30pm. March 26, 2010

  2. The anti-globalization movement • Ten years ago some protestors at the Seattle WTO Ministerial meeting, launching the first of the big anti-globalization demonstrations, wore turtle costumes. • Why? • They felt that a WTO panel had, in the name of free trade, negated the ability of the US to protect sea turtles, • simultaneously undermining national sovereignty & • the international environment.

  3. Central questions • Is trade good or bad for the environment? • Does globalization help or hurt in achieving the best tradeoff between environmental and economic goals? • Do international trade & investment allow countries to achieve more economic growth for any given level of environmental quality? • Or do they damage environmental quality for any given rate of economic growth? • How can globalization best be harnessed? • Do the WTO & environment conflict?

  4. Symmetric fears Free traders fear that talk of environmental protection will be used as an excuse by some industries to gain protection for themselves against competition from abroad. Environmentalists fear that talk of free trade will be used as an excuse to give inadequate weight to environmental goals and excessive weight to GDP.

  5. Widely agreed: openness to trade & other international activity is good for economic growth • In theory: classical comparative advantage (e.g., Ricardo) & more modern theories of trade based on imperfect competition (e.g., Krugman). • Empirically: many econometric studies. • E.g., one estimate: every .01 increase in a country’s trade/GDP ratio raises income 3 ½ % (over next 20 yrs)

  6. But what about effect of opennesson environmental quality,which is not capturedin GDP statistics?

  7. We care about both environmental quality and (market-reflected) real income • The objective, as always in economics: to attain the best “indifference curve” or “iso-welfare” curve possible, subject to technological constraints. • But environmental externalities are the classic case where the free market will not deliver the optimal tradeoff point. • Such market failure calls for government intervention. • Government regulation, if optimally designed, can deliver the optimum point (e.g., taxing pollution, not command & control). Environmentaldamage • Income per capita

  8. In practice, is growth per se good or bad for the environment? Environmental damage • EnvironmentalKuznets Curve:Grossman and Krueger (1995) Economic growth (whether trade-led or not) is good for the environment above a peak level of income. • EKC is confirmed for some pollution measures, e.g., SO2, • But generally rejected for CO2 . • Democracy matters too => need effective national regulation, not just demand for clean environment.

  9. Is trade itself good or badfor the environment? There are many possible effects of trade. They can be categorized according to Whether they (i) operate via GDP, just like investment, technology, or other sources of economic growth, or (ii) are peculiar to trade alone, and hold for a given level of GDP. Within each category, there are effects both beneficial for the environment, and detrimental.

  10. Is trade itself good or badfor the environment, in theory?

  11. The feared “race to the bottom” • Environmental regulation raises the cost of doing business. • Industry & labor worry about international competition. • The more open is a country to trade, the more pressure will they exert on their government to reduce the regulatory burden. • E.g., Barrett(1994) There are also fears that trade willaffect the allocation of pollution across countries • The “pollution haven” hypothesis: • trade encourages some countries to specialize in producing dirtier goods: • poorer countries • more capital-intensive countries • or less densely populated countries. • E.g., Levinson & Taylor(2004)

  12. RACE TO THEBOTTOM The impossible trinity of global environmental regulation Protectionism National sovereignty Environmental standards Unregulated emissions Multilateral governance Globalization

  13. Some examples of trade helping environment • Imports of environmentally friendly products(US ended 1980s tariffs & quotas on fuel-efficient Japanese autos, benefiting both consumer pocketbook & air quality) • Trade brings technological innovation, which can, for example, save energy. • MNCs bring global standards to where the local alternative is environmentally (even) less friendly. • Consumers can express enviro preferences via buying habits, e.g. “dolphin-free” labeling on tuna achieved its purpose. • Multilateral agreements • Potential for trade sanctions, as in Montreal Protocol • Kyoto Protocol • International trade in emissions permits: a win-win feature • Russia ratified as quid pro quo for EU supporting its WTO accession.

  14. More economic/environmentalwin-win ideas • Remove barriers to imports of environmental goods • USG proposal for Doha round: liberalize capital equipment & services used in environmental sector • US could let in imports of Brazil’s sugar/ethanol, again hitting multiple goals. • A global ban on subsidies to fossil fuelswould achieve both enviro goal of reducing carbon emissions and economists’ goals of reducing deficit spending& an economic distortion.

  15. Which tend to dominate in practice: • The effects of trade that are detrimental to the environment (e.g., race to the bottom)? • Or the effects of trade that are beneficial (e.g., US imports of fuel-efficient autos)? • It depends on what measure of environmental quality is at stake.

  16. SO2 concentrations tend to fall with openness,especially after controlling for democracy, cross-country Low-democracy High-democracy = Trade/GDP

  17. CO2 emissions/cap tend, if anything,to rise with openness

  18. But these rough correlations tell us little. • To isolate the effect of trade on a country’s environment, we need to control for other determinants, such as • income • democracy • population density. • Econometric analysis • Antweiler, Copeland & Taylor (2001); Copeland & Taylor (2004, 05) • Frankel & Rose (2004)

  19. Environmental quality equationSource: Frankel & Rose, R.Ec.& Stats., 2004 IV for GDP/cap: investment, education… IV for openness: geographically-based prediction of trade

  20. Is trade itself good or badfor the environment, statistically?Source: Frankel & Rose (2004)

  21. Do harmful or beneficial effects of trade dominate for environmental goals? Bottom lines: For SO2 at low incomes, harmful effects (EKC) work against beneficial effects at high levels of income, trade helps through both channels. For CO2 Even at high levels of income, trade continues to hurt. <= Absent an effective multilateral treaty, the popular will cannot be enacted.

  22. I have updated this econometric analysis • in a 2009 paper for the Swedish Globalisation Council -- putting together data for 1990-2004, • for 158 countries. • EKC (inverted U) shows up for PM10 , and water pollution. • Trade still appears to worsen CO2. • Again, the obvious explanation: the lack of a comprehensive global climate agreement.

  23. The anti-globalization movement:the first big protests in Seattle, 1999

  24. Why did they march together in Seattle?

  25. What do the anti-globalizers meanwhen they say the WTO is an intrusive undemocratic bureaucracy? • Its governance? = the member-country governments. • Technically one-country one-vote. • True, US & EU have disproportionate weight.But making it more democratic means giving more weight to India. Result: Policy gives lower priority to the environment. • The Articles of Agreement? Hard to object to, as we will see. • The WTO staff? A few thousand powerless technocrats working in a building on Lake Geneva. • WTO panel rulings that interpret the rules? That must be it.

  26. Typical WTO panel cases • Tariffs or other measures that discriminate against producers in some trading partners, • either in favor of other trading partners (potential violation of MFN principle of Article I)or • in favorof “like products”from domestic producers (potential violation of national treatment provision of Article III).

  27. Typical WTO panel cases,continued • If a targeted country files a WTO complaint alleging such a violation, the question is whether the measure is permissible under Article XX • which allows for exceptions to the non-discrimination principles for environmental reasons (XXb), • provided that the measures in question are not “a means of arbitrary or unjustifiable discrimination” nor a “disguised restriction on international trade.”

  28. Mutual respect Drafters in Kyoto and Genevashowed more consideration for each other than the rank & file of environmentalists and free traders. The Kyoto Protocol text: Parties should “strive to implement policies and measures...to minimize adverse effects on international trade...” ; UNFCCC features similar language

  29. Mutual respect,continued • WTO regime is equally solicitous of the environment: • Article XX allows exceptions for health & conservation. • Preamble to 1995 Marrakesh Agreement establishing WTO seeks “to protect and preserve the environment;” • 2001 Doha Communiqué starting new round of negotiations: “the aims of ... open and non-discriminatory trading system, and acting for the protection of the environment ... must be mutually supportive.”

  30. The Kyoto Protocolwas in my view a useful foundation. But it lacks: • Provisions for emission targets in future years • Targets for US, China & other developing countries • An enforcement mechanism • including an incentive for holdouts to join, and • enforcement of the agreement. • Some ask: Could trade sanctions be the mechanism?

  31. Will the global climate regimecollide with the global trade regime?

  32. Leakage and lost competitiveness= what “unfairness” means in rich countries Could border measures give non-participants incentive to join, and level the playing field in the meantime? • Yes, in theory. • If properly designed, they could even be WTO-consistent, • building on precedents • and recent D-G Lamy speeches (2 Nov., 2009). • In practice, however, border measures written by politicians will almost certainly be discriminatory, WTO-inconsistent, and undermining of climate goals.

  33. Possible application of trade barriersby US climate change legislation: Climate Change bills in Congresscontain some trade measures: requiring permits for energy-intensive imports or granting allowances to affected industries. Washington might not realize that the US could qualify to be the victim of legal sanctions before it is the wielder of them.

  34. Possible application of trade barriersby EU:Directive of the European Parliament & of the Council, Paragraph 13,amending Directive 2003/87/EC so as to improve and extend the EU greenhouse gas emissions allowance trading system; Brussels, 2008: “Energy-intensive industries which are determined to be exposed to significant risk of carbon leakage could receive a higher amount of free allocation, or an effective carbon equalization system could be introduced with a view to putting EU and non-EU producers on a comparable footing. Such a system could apply to importers of goods requirements similar to those applicable to installations within the EU, by requiring the surrender of allowances.”

  35. Would carbon-import penalties be compatible with the WTO? Question (1): GHG emissions are generated by so-called Processes and Production Methods (PPMs). Does that rule out trade measures against them? Question (2): What specific trade control design is appropriate?

  36. Precedent (1): Montreal Protocol on stratospheric ozone depletion Trade controls had two motivations: (1) to encourage countries to join, and (2) if major countries had remained outside, would have minimized leakage, the migration of production of banned substances to nonparticipating countries. In the event (1) worked, so (2) not needed.

  37. Precedent (2): The true meaning of the 1998 WTO panel shrimp-turtle decision • New ruling: environmental measures can target, not only exported products(Article XX),but also partners’ Processes & Production Methods (PPMs), • subject, as always, to non-discrimination (Articles I & III). • US was able to proceed to protect turtles, without discrimination against Asian fishermen. • Environmentalists failed to notice or consolidate the PPM precedent.

  38. Precedent (3): In case there is any doubt that Article XX, which uses the phrase “health and conservation,” applies to climate change, … • a 3rd precedent is relevant: • In 2007, a WTO Appellate Body decision regarding Brazilian restrictions on imports of retreaded tires confirmed the applicability of Article XX(b): • Rulings “accord considerable flexibility to WTO Member governments when they take trade-restrictive measures to protect life or health… [and] apply equally to … measures taken to combat global warming.”

  39. Central message: border measures to address leakage need not necessarily violate sensible trade principles or the WTO, but there is a great danger that they will in practice. The big danger: If each country imposes border measures in whatever way suits national politics, they will be poorly targeted, discriminatory, and often disguisedly protectionist; they will run afoul of the WTO, and will deserve to. We need a multilateral regime to guide such measures. Some subjective judgments as to principles that should guide design of border measures…

  40. Appropriate border adjustments could be tariffs or, equivalently, a requirement that importers surrender tradable permits.Guiding principles include: • Measures should follow guidelines multilaterally-agreedamong countries participating in the targets of KP & its successors. • Judgments as to findings of fact(who is complying, etc.)should be made by independent expert panels. • Measures should only be applied by countries that cut their own emissions in line with the KP & its successors,against countries not doing sodue to either refusal to join or failure to comply. • Import penalties should target fossil fuels, and a half dozen of the most energy-intensive major industries: aluminum, cement, steel, paper, glass, iron & chemicals.

  41. Summary of conclusions • Has globalization damaged the environment • through a “race to the bottom” in regulation? • Empirical studies of cross-country data find no detrimental effects of trade on some measures of environmental degradation such as SO2 air pollution, controlling for income.

  42. Summary of conclusions,continued • Thus globalization and the environment need not necessarily be in conflict. • Trade & growth give countries the means to clean the air, • provided they have effective institutions of governance in place. • For local air pollution, the appropriate governance is at the national level.

  43. Summary of conclusions,continued • But the evidence does suggest that trade & growth can exacerbate other measures of environmental degradation, particularly CO2 emissions. • The difference can be explained by the observation that CO2 is a global externality • which cannot be addressed at the national level due to the free rider problem. • We need institutions of governance at the multilateral level. • These have not been in place, in the past.

  44. The solution • Greater international cooperation on environmental and trade issues, • so that we can get the best of both. • Very specifically, the UNFCCC or (more likely) the WTO should agree on guidelines for penalties on carbon-intensive imports that countries are allowed to impose on each other.

  45. What form should border measures take? • Best choice: multilateral sanctions. (Not likely.) • Next-best: national sanctions adopted under multilateral guidelines • Penalties can only be applied by participants-in-good standing • Judgments to be made by technical experts, not politicians • Penalties only in 6or8 of the most relevant sectors (aluminum…). • Third: No border measures. • Each country chooses carbon tariffs as it sees fit. • Worst choice: national measures are subsidies (e.g., free permits) to adversely affected firms.
