12 A recent UNITAR Study by Serwer, International Environmental Regulation: Means of Achieving Environmental Quality (Provisional Draft, 1971) distinguishes, inter alia, quality standards, discharge standards, and operational standards. The Preparatory Committee for the Stockholm Conference, at its 3rd Session, drew a distinction between “criteria” and three types of “standards”: primary protection standards, derived working levels, and action levels. The report of the inter-governmental working group on the universal declaration (note 4 above), Annex I at 4, also calls for “agreements for the establishment of international standards of environmental quality” (Draft Fundamental Principle No. 12); and cf. the resolution of the International Parliamentary Conference on the Environment (Bonn, June, 1971) for “common environmental standards applicable to the contracting nations.”

13 E.g., see the recommendations for various Federal standards contained in President Nixon’s Message to Congress of Feb. 8, 1971, “Progress for a Better Environment,” H.R. Doc. No. 46, 92nd Cong., 1st Sess. (1971); or the proposed “national emission standards” in Canadian Bill C-224 (Clean Air Act), 28th Pari., 3rd Sess. (1971); and cf. the “environmental quality standards” under Art. 9 of the Japanese Basic Law for Environmental Pollution Control (1967, as amended in 1970); see “Problems of the Human Environment in Japan,” National Report Submitted by the Government of Japan for the U.N. Conference on the Human Environment, Annex I (1971). Generally on a “safe minimum standard” as an objective of conservation policy, see Ciriacy-Wantrup, Resource Conservation: Economics and Policies 251–268 (3rded., 1968).

15 Besides the activities of the U.N. agencies and other international bodies mentioned below (notes 20 to 58), particular reference must be made to the industrial standardization carried out by the non-governmental International Organization for Standardization (ISO) founded in 1946, which supplements the inter-governmental unification of measuring standards by the International Union of Weights and Measures (established by the Paris Convention of May 20, 1875, 1 de Martens, Nouveau Recueil Général des Traités (2nd Series) 663, T.S. 378, as amended on Oct. 6, 1921, 17 L.N.T.S. 46, T.S. 673) and the harmonization of rules on measuring instruments by the International Organization of Legal Metrology (established by the Paris Convention of Oct. 12, 1955, 560 U.N.T.S. 3).

16 Some of the legal implications of standard-setting have been touched upon in several monographs dealing with the “lawmaking” activities of international organizations. See Merle, , “Le pouvoir réglementaire des institutions intemationales,” 4 Annuaire Français de Droit International 341 (1958)CrossRefGoogle Scholar; Schulz, Entwicklungsformen Internationaler Gesetzgebung (1960); Saba, , “L’activité quasi-législative des institutions spécialisées des Nations Unies,” 111 Hague Academy, Recueil des Cours 607 (1964)Google Scholar; Erler, , “International Legislation,” 2 Canadian Yr. Bk. Int. Law 153–163 (1964)CrossRefGoogle Scholar; Skubiszewski, , “Forms of Participation of International Organizations in the Lawmaking Process,” 18 Int. Organization 790–805 (1964)CrossRefGoogle Scholar; idem, Uchwaly Prawotworcze Organizacji Miedzynarodowych (1965); Detter, Law-Making by International Organizations (1965); Skubiszewski, , “Enactment of Law by International Organizations,” 41 Brit.

General Assembly, 21st Sess., Official Records, Supp. 9 (1966): After stating (at 62) that “the development of international organization and the tremendous increase in multilateral treaty-making have made considerable impact on the process of amending treaties,” the Commission (at 64) explicitly refers to the displacement of the general rule “in some modern treaties,” citing the conventions on rail and road transport (notes 32, 33 below).

See Codding, The International Telecommunication Union: An Experiment in International Co-operation 28 (1952).

61 E.g., in the International Whaling Commission (note 38); also in the former ICAN (note 23), now superseded by ICAO; and in the UNCITRAL proposal (note 37). We have omitted here conventions requiring unanimous adoption of standards, which are not fundamentally different from traditional international lawmaking; e.g., see the Convention Concerning Fishing in the Black Sea, adopted on July 7, 1959, 377 U.N.T.S. 203, or the Oslo draft convention (note 3 above), Art. 18.

63 This division is somewhat different from the ones suggested by Skubiszewski and Detter (op. cit. note 16 above), in that it distinguishes according to the binding force of standards rather than according to the procedure (majorities) required for their adoption.

86 Fleischer (op. cit. note 3 above), Art. 52; explained (at 67) as a combination of the systems under the 1954 Oil Pollution Convention (note 84 above) and of the 1959 Northeast Atlantic Fisheries Convention (note 40 above), which “may prove to be successful also in regard to other types of pollution.” Detter and Skubiszewski (op. cit. note 16 above) describe the principle as “contracting out.” Note, however, that this term has been used in a different context by the International Law Commission; viz., for inter se contractual modifications of a treaty under Art. 41 of the 1969 Vienna Convention. See the ILC commentary (op. cit. note 18 above) at 65, and cf. the materials cited in Rosenne, The Law of Treaties: A Guide to the Legislative History of the Vienna Convention 245–247 (1970).

87 No detailed figures are available. According to the ICAO Secretariat, Memorandum on ICAO 23 (6th ed., 1969), no majority of member states had ever opted out of the approximately 600 regulations which had become effective until then by way of annex adoption or amendment. In UPU, the “abstention” procedure had been used some 122 times from 1874 to 1963, according to Codding, op. cit. note 22 above, at 107. In WHO, 73 reservations were made by member states until 1957, of which 38 were rejected (note 90 below); see WHO, The First Ten Years 260 (1958).

88 As regards air navigation over the high seas, see Art. 12(3) of the Chicago Convention (note 24 above); Carroz, , “International Legislation on Air Navigation Over the High Seas,” 26 J. Air Law and Commerce 159 (1959)Google Scholar; Drion, , “The Council of ICAO: An International Legislator Over the High Seas,” Studi in Onore di Antonio Ambrosini 326 (1957)Google Scholar; Buergenthal, note 82 above, at 80.

89 On the de facto “sanctions” against opting out under Arts. 39–40 of the ICAO Convention, see Jones, , “Amending the Chicago Convention and its Technical Standards: Can Consent of All Member States be Eliminated?” 16 J. Air Law and Commerce 189 (1949)Google Scholar; Skubiszewski, op. cit. note 16 above, 41 Brit. Yr. Bk. Int. Law 214 (1968); Buergenthal, op. cit. note 82 above, at 86.

90 Art. 101 of the International Health Regulations (1969) of WHO (note 26 above) provides that “reservations” to the regulations must be accepted by the World Health Assembly in order to be valid. On past experience with this system see Detter, op. cit. note 16 above, at 241.

91 Clauses to this effect, usually requiring a two-thirds majority decision, may be found in the amendment procedures of several international organizations: e.g., ICAO (note 24 above), Art. 94 (b), and IMCO (note 71 above), Art. 52. See Zacklin, The Amendment of the Constitutive Instruments of the United Nations and Specialized Agencies (1968); and cf., for similar clauses in some international commodity agreements, U.N. Secretariat, Handbook of Final Clauses (ST/LEG/6) 145 (1957). The coercive effect of this procedure has been criticized as “un système autoritaire camouflé” by Scelle, , “La révision dans les conventions générales,” 42 Annuaire de l‘Institut de Droit International 185 (1948)Google Scholar. The Road Traffic Convention (note 33 above) in Art. 31 (4) expressly excludes application of this sanction to two of the more controversial technical annexes (Nos. 1 and 2).

92 E.g., see Art. 9 (3) of the Southeast Atlantic Convention (note 43 above): “If an objection is presented within the ninety-day period referred to in the preceding paragraph, any other Contracting Party may present an objection at any time within a further period of sixty days or within thirty days after notification of an objection presented by another Contracting Party made within the further sixty-day period.”

93 Most elaborate in this respect is the “reconfirmation system” of the Atlantic Tuna Convention; see Carroz and Roche, loc. cit. note 42 above, at 689.

94 E.g., the Rail Transport Conventions (note 32 above: CIM Art. 69, CIV Art. 68): “The decision [of the Revision Commission] shall be deemed to be accepted unless within a period of three months from the date of notification not less than five Governments of Contracting States have lodged objections” [four months according to a 1969 draft revision]. Under the Northeast Atlantic Convention (note 40 above) and the Southeast Atlantic Convention (note 43 above), objections by at least three states are sufficient to prevent recommendations from becoming binding erga omnes (though not from being voluntarily accepted by other states inter se).

95 E.g., under the Chicago Convention (note 24 above), the Northwest Atlantic Convention (note 41 above), the Atlantic Tuna Convention (note 42 above), and the Draft Convention on the Export, Import and Transit of Certain Species of Wild Animals and Plants (note 58 above).

97 See, generally, Seidl-Hohenveldern, , “Transformation or Adoption of International Law into Municipal Law,” 12 Int. and Comp. Law Q. 88 (1963)Google Scholar. Transformation of international standards into national law is frequently delegated (by way of enabling legislation) to a lower level of statutory enactment than transformation of treaties; see the examples given by Erler, loc. cit. note 16 above, at 162, and by Skubiszewski (toe. cit. note 16 above), 41 Brit.

One could also envisage a permanent inspection system, either directly by international institutions (similar to the IAEA and Euratom safeguards and safety controls; cf. McKnight, Atomic Safeguards: A Study in International Verification, UNITAR, 1971) or on the basis of information from national institutions (as under the ILO Labor Inspection Convention No. 81 of July 11, 1947, 54 U.N.T.S. 3; cf.

In addition, the following standards are now in preparation: lists of protected species under the IUCN Draft Convention (note 58); water standards under the draft conventions of the Council of Europe (note 46) and of the Lake Chad Basin Commission (note 47). International standards for measuring techniques set by the International Union of Weights and Measures (note 15; e.g., for radiation measurement) and by the International Organization for Standardization (note 15; e.g., for toxicity measurement in chemical products) should also be mentioned in this context.

For background information, see Proceedings, Conference on Aircraft and the Environment 218–239 (Society of Automotive Engineers and U.S. Dept. of Transportation, 1971); cf. Sand, , “Intemationaler Umweltschutz und neue Rechtsfragen der Atmosphärennutzung,” 20 Zeitschrift fur Luftrecht und Weltraumrechtsfragen 109, 129 (1971)Google Scholar.

121 Cf. the recommendations of the 1955 Conference on the Conservation of the Living Resources of the Sea (pars. 43-e and 43-f) to the effect that, where regulatory powers are granted to inter-governmental bodies, these powers should be sufficiently broad to ensure the full application of all suitable conservation measures which have been arrived at on the basis of adequate scientific investigations, and that there should be facilities for adjusting and reviewing the convention to meet changing conditions and to take advantage of advancing technical and scientific knowledge; U.N., Report of the International Technical Conference on the Conservation of the Living Resources of the Sea (Doc. A/CONF.10/6)5–6 (1955).

122 E.g., see the maximum levels (“tolerances” and “practical residue limits”) for pesticide residues in food, published on the basis of international expert committee findings by the joint FAO-WHO Codex Alimentarius Commission (note 36 above): Recommended International Tolerances for Pesticide Residues, 1st Series: FAO Doc. CAC/RS. 2 (1969); 2nd Series: FAO Doc. CAC/RS. 35 (1970). On the definition of standards in economic terms of “results” and “performance” see Ciriacy-Wantrup, op. cit. note 13 above, at 257–259. The derived working levels as defined by the Preparatory Committee for the Stockholm Conference (note 12 above) include “environmental or ambient quality standards, maximum permissible limits and maximum allowable concentrations.”

123 See Ciriacy-Wantrup, op. cit. note 13 above, at 35–47. For background information on the depletion of bioresources see the international lists of rare and endangered species contained in the IUCN Red Data Books (1966 to date). A combination of qualitative and quantitative standards (“essential or desirable degree of integrity”) is suggested by Frankel, , “Genetic Conservation in Perspective,” in Genetic Resources in Plants: Their Exploration and Conservation 469 (Frankel, and Bennett, eds., 1970)Google Scholar. The concept of “environmental integrity” also appears in the Canadian Draft Declaration on the Human Environment (Arts. 2 and 3) submitted and discussed at an inter-governmental working group session in May, 1971; see the report, U.N. Doc. A/CONF. 48/PC. 12, Annex IV, at 13 (June, 1971). The UNITAR Study and the recommendations of the Preparatory Committee (note 12 above), which focus on pollution only, do not include depletion standards. See, however, on the interdependence of resource depletion and degradation: Natural Resources, Quality and Quantity (Ciriacy-Wantrup and Parsons eds., 1967).

124 Besides maximum limits (i.e., absolute prohibition of all emissions exceeding a specified “intolerable” level), an international system of effluent charges (i.e., progressive compensation payments due for all emissions exceeding a specified “undesirable” level) is also conceivable; e.g., see the OECD proposals for international tolerance limits, as reported in the New York Times of Feb. 19, 1970, p. 11, col. 1. A progressive fee to be imposed on users of vehicles with combustion engines, with the proceeds to be allocated to users of non-polluting vehicles is suggested by Contini, E., “The Elimination of Smog,” in Ecocide and Thoughts Towards Survival 141 (Fadiman, and White, eds., 1971)Google Scholar.

125 E.g., the European Agreement on the Restriction of the Use of Certain Detergents in Washing and Cleaning Products, adopted by the Council of Europe on Sept. 16, 1968, 16 European Yearbook 335 (1968), and already implemented by several member states. It may be noted, however, that any revision of the 80 percent bio-degradability level established by this Agreement (Art. 1) requires diplomatic consultations (Art. 3).

126 On the potential effect of anti-pollution laws as new non-tariff trade obstacles, see G. and V. Curzon, Hidden Barriers to International Trade 30–31 (1970), and particularly the recommendations on “international economic implications of environmental control and pollution abatement programs,” in U.S. Commission on International Trade and Investment Policy, United States International Economic Policy in an Interdependent World 129 (1971). A step towards harmonization of standards has recently been made by the Organization for Economic Co-operation and Development (OECD) with the introduction, for an initial period of two years, of a “Procedure for Notification and Consultation on Measures for Control of Substances Affecting Man or his Environment,” adopted on May 18, 1971, OECD Doc. C (71) 73/Annex (1971); cf. the earlier OECD Council Resolution of March 2, 1971, Doc. C (71) 43 (1971). Cf. the notification requirement for food additive controls pursuant to Res. 23.50 adopted by the World Health Assembly on May 21, 1970; WHO Official Records (No. 184) 26 (1970); and especially the work of the Codex Alimentarius Commission (note 36 above).

127 Under the ICAO system of “notification of differences” (notes 24 and 82 above), governments are usually requested to inform the Organization by a fixed date: (a) whether they wish to register disapproval concerning any part of the standards; (b) whether differences will exist on the specified date of uniform applicability or thereafter between national regulations or practices and the provisions of the standards; and (c) as of which date or dates they will have complied with the provisions of the standards.

128 Cf. the “directives” (binding as to objectives, optional as to means) under the Euratom Treaty (note 64 above) and in the European Communities generally for the approximation or harmonization of legislative and administrative provisions, Arts. 100–102 of the Treaty Establishing the European Economic Community, of March 25, 1957, 298 U.N.T.S. 3, 51 A.J.I.L. 865 (1957). Another precedent for this approach are the Objectives for Boundary Water Quality Control, first recommended in 1950 by the U.S.-Canadian International Joint Commission (established under the Boundary Waters Treaty of Jan. 11, 1909, T.S. 548). The flexible concept of water quality “objectives” (technical criteria to be met in order to maintain the waters in satisfactory condition, yet allowing governments a choice of methods to achieve the objectives) proved so effective that it was ultimately embodied in the U.S. Federal Water Quality Act of 1965; see Bilder, , “Controlling Great Lakes Pollution: A Study in U.S.-Canadian Environmental Cooperation,” 70 Mich. Law Rev. (forthcoming, 1972)Google Scholar.
