Sustainable Development under Canadian Law
Paule Halley and Pierre-Olivier DesMarchais
Sustainable development represents a new paradigm, casting doubt on the belief that development can be based on sporadic and unlimited economic growth thanks to the planet earthās ability to perpetually provide adequate resources to keep pace with it. That belief has been replaced with uncertainty and concern in the face of deteriorating ecosystems, climate and biodiversity, and other risks associated with irreversible changes. Sustainable development is trying to become established for the long term and to sever its ties with any developmental approach that does not take into account the restricted nature of the planet earthās resources.1
The implementation of sustainable development has mobilized most national and international organizations and a great number of participants. The task at hand is colossal and meets with much resistance. For legal experts, sustainable development remains a dynamic concept, the subject of much debate and reflection.2 Here, we will content ourselves with introducing the origins of sustainable development, outlining significant milestones in its development on the international stage, and examining its implementation in Canadian law through its guiding principles.
Origins and Definitions of Sustainable Development
The concept of āsustainable developmentā first appeared on the international stage in 1980, in World Conservation Strategy published by the International Union for Conservation of Nature and Natural Resources: āFor development to be sustainable it must take account of social and ecological factors, as well as economic ones.ā3 It then gained prevalence in 1987 with the publication of the report Our Common Future by the World Commission on Environment and Development (the Brundtland Report): āSustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.ā4 The two main principles that inform these definitions are equity and integration, which have established the present-day model of sustainable development and influence the legislation and interpretations surrounding its scope, conditions of application, and implementation.
It was at the second United Nations Conference on Environment and Development, held in Rio de Janeiro in 1992, that the international community undertook to establish āa new and equitable global partnershipā through the integration of the goal of sustainable development in policy and public decision making. The Rio Declaration on Environment and Development 5 clearly defines the concept of sustainable development, most notably its conditions of equity: āthe right to development must be fulfilled so as to equitably meet developmental and environmental needs of present and future generationsā;6 and integration: āin order to achieve sustainable development, environmental protection shall constitute an integral part of the development process and cannot be considered in isolation from it.ā7
Since then, this change in the approach to development has been reiterated by the international community on numerous occasions8 and has flourished in the areas of both international environmental law and international trade.9 For example, the preambles to the Marrakesh Agreement Establishing the World Trade Organization10 and the North American Free Trade Agreement11 recognize that the rules governing international trade must favour the sustainable use of resources and that member states are obligated to promote sustainable development.12
The goal of sustainable development in international law is given concrete expression in guiding principles that set out its purpose, means of application and implementation. The Rio Declaration, for example, lays down 27 guiding principles, among which it is possible to distinguish those that are inherent to sustainable development from those that are operational principles.13 Today, these guiding principles represent the foundation for many international conventions. Thus, the principle of public participation is at the heart of the Aarhus Convention on Access to Information, Public Participation in Decision-making and Access to Justice in Environmental Matters;14 the precautionary principle was codified in the 1996 Protocol to the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter,15 while the prevention principle is the basis for the United Nations Convention on the Law of the Non-navigational Uses of International Watercourses,16 and the procedure for evaluating environmental impact contained in the Convention on Environmental Impact Assessment in a Transboundary Context.17
