Renewable Energy and Trade: Interpreting against Fragmentation
Published online by Cambridge University Press: 09 March 2016
Summary
Several disputes relating to renewable energy are underway at the World Trade Organization (WTO). The Appellate Body has released its first decision on this subject on the feed-in tariff for electricity in the province of Ontario. The disputes raise once again the issue of the relationship between international trade law and environmental protection. Evolving WTO jurisprudence should be able to resolve many of the difficulties, although the crucial problem of the treatment of production and processing methods remains obscure after the Canada – Renewable Energy decision. Questions of fundamental theory lie close to the surface of these debates. The recent expansion in the number of international regimes and tribunals highlights the importance of approaches to interpretation in public international law. As countries negotiate new treaties to address the needs of global society, potential conflicts and overlapping provisions are likely to appear. Differences of opinion about reliance on non-WTO treaties in the WTO dispute settlement system illustrate problems that can be anticipated in several fora. To achieve workable solutions for renewable energy disputes and many others, interpretation should promote the harmonious integration of obligations, in accordance with the intent of the negotiators.

16 US – Tuna II, supra note 5 at paras 335, 338. The Appellate Body reversed a Panel finding of breach of Article 2.2 of the TBT Agreement because the Panel had incorrectly assessed Mexico’s argument over a less restrictive alternative measure. Due to a lack of evidence, the Appellate Body did not rule on whether there was a breach of Article 2.2. In 2001, the Appellate Body found that a distinction based on production and processing methods was justified pursuant to GATT Article XX.

Ibid, Annex B-11 (Integrated Executive Summary of the United States). Canada has reported that the Ontario government issued a ministerial directive that removed large-capacity projects from the content requirement for equipment and lowered the requirement for smaller projects. As well, the province is proceeding with a statutory change that will permit procurement of electricity under the feed-in tariff free from the requirement.

26 Ontario’s electricity system operated as a hybrid system, in which public and private entities were involved in generation, transmission, distribution, and retailing. Electricity was sold to retail consumers by a provincial government agency, by local distribution companies (including public municipal utilities), and by some licensed private sector retailers.

Qin would also use the reference to “discrimination between countries where the same conditions prevail” in the introductory paragraph of GATT Article XX to support extended consideration of regulatory purpose for analysis of exemptions under this article.

35 James Flett has argued in favour of an “aim-and-effects” test for the review of the treatment standard required in trade agreements and also in investment agreements, which often lack an exemption clause. See Flett, James “WTO Space for National Regulation: Requiem for a Diagonal Vector Test” (2013) 16(1)J Int’l Econ L 37 CrossRefGoogle Scholar. A major hurdle for the analysis is the one identified of respect for differing treaty texts. As investment agreements are updated, more may be modified to include specific exemption clauses.

38 In US – COOL, supra note 6, Canada argued unsuccessfully that the purpose of the US requirement for detailed records on where cattle were born, raised, and slaughtered was trade protectionism rather than the provision of information to consumers (at para 354). The panel had relied on evidence of a social norm that consumers want information on the origin of products (at para 441). While the Appellate Body was unsupportive of the panel’s reference to social norms to identify legitimate objectives (at para 448), it upheld the panel determination that the objective of the US measure to provide consumer information was legitimate (at para 453).

40 US – Tuna II, supra note 5 at para 225.
41 US – Clove Cigarettes, supra note 4 at para 174. The idea that a detrimental impact must be due exclusively to a legitimate regulatory distinction might be considered as establishing a test that differs from the requirement in the introductory paragraph of GATT Article XX that measures not constitute arbitrary or unjustifiable discrimination between countries where the same conditions prevail. Zhou argues that the two tests are not that far apart, since they would both depend on the reasonable availability of alternate less discriminatory means. Zhou, supra note 33 at 1120.
42 It is not clear what effect the interpretation of “treatment no less favourable” in US – Clove Cigarettes, supra note 4, will have on interpretation of the same phrase in GATT Article III:4. Since the GATT context is different and includes the specific exemptions of GATT Article XX, there may be no need to consider legitimate objectives directly at the stage of a GATT Article III analysis. There could be a possible linkage to a consideration of purpose in the identification of like products, as outlined earlier. Another issue that will undoubtedly be explored in future WTO jurisprudence is how the US – Clove Cigarettes interpretation of Article 2.1 will relate to the legitimate objectives listed in Article 2.2 of the TBT Agreement. In US – COOL, supra note 6, for example, if the Appellate Body had completed the Article 2.2 analysis and determined that the obstacle to trade was justified by the objective of providing consumer information, would it still have been able to find that the same measure breached Article 2.1 because the information demanded was disproportionate to the same objective? Will a proportionality analysis be used for both Articles 2.1 and 2.2 ?

45 GATT Working Party, Border Tax Adjustments, Doc L/3464 (2 December 1970), BISD 18S/97 at para 15: “taxes occultes.” The French version of GATT Article II:2 (a) refers to “ une marchandise qui a été incorporée dans l’article importé” seeming to require that the product tax be on components that have been incorporated into the imported goods, which does not describe greenhouse gases (GHGs) emitted during production.

50 A counter-argument is that trade in the emission certificates can be detached from goods and classified as a service subject to the General Agreement on Trade in Services, 1869 UNTS 183 (in force 1January 1995) [GATS], but not to provisions that relate to products. Classification will depend on the details of any particular measure and, probably, on the availability of secondary markets in emission certificates. A measure could also be subject to rules under the GATT, the TBT Agreement, and the GATS. If the GATS applies exclusively, then any national treatment requirement would depend on whether a commitment had been made under Article XVI of the GATS. The exemption clauses would be GATS Articles XIV and XIVbis; and subsidies would be governed by GATS Article XV rather than the SCM Agreement, supra note 19. See generally Howse and REIL Project, supra note 34, for the argument that the GATS has wide application to energy trade; Vranes, Erich “Climate Change and the WTO: EU Emission Trading and the WTO Disciplines on Trade in Goods, Services and Investment Protection” (2009) 43(4) J World Trade 707 Google Scholar.

76 O’Brien, Julia “The Equity of Levelling the Playing Field in the Climate Change Context” (2009) 43(5) J World Trade 1093 at 1110 Google Scholar. As O’Brien argues, the same issue can affect the interpretation of GATT Article III as applied to the border adjustment: “Unless an exporting country could be expected to reduce its carbon emissions to an equal degree as the importing country, a carbon tax that charged imported goods the equivalent of what they would have had to pay if they had been produced domestically would amount to placing an inequitable tax burden on producers in the exporting country and may thus be inconsistent with the second sentence of Article III(2).” Ibid at 1108–9.
77 It has been argued that such discounting would also be required for adjustments to be acceptable under Article II. See Pauwelyn, supra note 44 at 21–22; McLure, supra note 48 at 285–87. In addition, free allowances for exporters could be seen as illegal export subsidies. Maruyama, supra note 47.

123 Ibid at 168. The wide view of a conflict is now part of WTO jurisprudence. The Panel in United States – Certain Measures Affecting Imports of Poultry from China refers to both the strict view of conflict arising “where… obligations are mutually exclusive in the sense that a Member cannot comply with both obligations at the same time” and the wider view “where a rule in one agreement prohibits what a rule in another agreement explicitly permits.” United States – Certain Measures Affecting Imports of Poultry from China, Doc WT/DS392/R, Panel Report (25 October 2010) at para 7.63, n 240, citing for the first view Turkey – Restrictions on Imports of Textile and Clothing Products, Doc WT/DS34/R, Panel Report (adopted with the Appellate Body Report, 19 November 1999) at para 9.92, and for the second view European Communities – Regime for the Importation, Sale and Distribution of Bananas, Doc WT/DS27/R, Panel Report ( adopted with Appellate Body Report25 September 1997) at para. 7.159.

126 Ibid at para 118: “The example… was that of maritime carriage of hazardous substances. Depending on what the interpreter sees as the relevant consider-ation, the case comes under one or another set of rules as lex specialis: is the point of the law to advance trade, flag or coastal State jurisdiction, or environ-mental protection? None [of] these perspectives enjoys intrinsic priority over the others. This is why, in a hard case, a justifiable decision would have to take all of these into account.”
127 Jenks, supra note 119 at 450.
128 Lex specialis is not solely a priority rule, replacing one norm with another. It can operate to indicate the appropriate intensity of one norm in relation to another or to create partial carve-outs that leave more general provisions in place across a range of meanings. Legislative measures, after all, may have more than one purpose. As an interpretive technique, lex specialis can function as part of a general teleological approach.
