The international legal and institutional context for sustainability labelling and certification is being determined by a number of international governmental and non-governmental organisations. In this context, the UN performs a prominent role, as far as it has adopted a large number of principles, norms, and recommendations in the field of sustainable development, environmental protection, labour conditions, human rights and development. These standards constitute a global framework addressed to Member States, but also indirectly to other international actors. In the environmental field, the UN has promoted the establishment of several international agreements, inter alia including the Convention on International Trade in Endangered Species of Wild Fauna and Flora, the UN Convention on the Law of the Sea, the Vienna Convention for the Protection of the Ozone Layer, the Convention on Biological Diversity and the UN Framework Convention on Climate Change. The 1948 Universal Declaration of Human Rights, the conventions produced by the UN (International Covenant on Civil and Political Rights 1966 and International Covenant on Economic, Social and Cultural Rights 1966), and the core conventions of the ILO (forced labour, freedom of association and right to organise, collective bargaining, equal remuneration, abolition of forced labour, discrimination, minimum age and worst forms of child labour) represent the most widely accepted codification of human rights standards in international law.
Of direct relevance for sustainability labelling and certification within the WTO are the GATT 1947/94, the GATS, and the TBT Agreement. From the perspective of the WTO trade rules, the development of sustainability labelling and certification schemes is mainly conditioned by the persistent legal uncertainties regarding the legality of schemes based on non-product related process and production methods. It seems that this product/process distinction does not properly fit into the concept of sustainable development, since this concept adopts an integrated approach as regards to economic development, environmental protection, and improvement of the populations social conditions. Contrary to this integrated perspective, the product/process distinction implies a separate consideration of the product and the social and environmental conditions within which it was produced. Keeping the product/process distinction within the multilateral trading system and ignoring the PPMs non-reflected in the final product may constitute a relevant concern for those that are in favour of the integrated approach of sustainable development.
For the EU, sustainable development has become an operative goal since 1997, when the Treaty of Amsterdam introduced the concept of sustainable development into EC law. The Unions political and legal commitment to sustainable development has consequences for almost all policy fields under EU authority and also influences the legal and institutional context for labelling and certification. Apparently, social and environmental labelling and certification play a significant role in the sustainable development strategy of the EU. The EU, however, is faced with both internal and external challenges that make sustainability labelling and certification quite difficult to handle as a policy tool. On the external front, developing countries are the main opponents of these schemes, which they consider illegal and economically unsound trade barriers. As regards the internal front, the business community stands against any kind of regulation of commercial practices that refers to the concept of sustainable development. On the opposite side, other actors invoke an intervention of public powers aimed at safeguarding the integrity and the viability of certain labelling and certification schemes, threatened by the proliferation of sustainability claims made by powerful economic actors.
Several major organisations from the business community and civil society are also contributing to environmental and social governance. Some of these organisations are actually seeking corporate commitment to sustainable development through the creation of procedures for endorsement and participation. These initiatives differ in their level of detail and the need for further interpretation. Furthermore, they may be competing, parallel, or complementary to each other, largely depending on the circumstances under which they are applied. Ultimately, these initiatives may offer a contribution to the tapestry of actions that is needed to stimulate social responsibility by companies, and that consists of several instruments, one of which is sustainability labelling and certification.
