MEAs and non-binding instruments
Multilateral environmental agreements
Although some international environmental treaties date back to early in the 20th century, it was not until the 1960s that concern about environmental pollution and the depletion of natural resources led to the kind of binding multilateral environmental agreements (MEAs) that we know today. The evolution of environmental agreements and legislation has fallen into two inter-related and overlapping generations. The first was one of single issue, use-oriented, mainly sectoral agreements and legislation, primarily addressing allocation and exploitation of natural resources such as wildlife, air and the marine environment; the second generation of agreements is more trans-sectoral, system-oriented and holistic. The second generation instruments are supplementing rather than replacing the first.
In this chapter, 10 major MEAs (see box below) are dealt with in much more detail than the others, and their current state of ratification is summarized both by region and by sub-region in the sections that follow. The graph below shows how ratification has grown over time.
In the early 1900s, environmental agreements, such as those covering fish or birds, were aimed more at regulating their exploitation and maintaining their economic usefulness than at protection for its own sake. One of the first international environmental agreements was the 1900 Convention for the Preservation of Animals, Birds and Fish in Africa, signed in London by the European colonial powers with the intention of preserving game in East Africa by limiting ivory exports from the region (Ruester and Simma 1975, Brenton 1994).
As knowledge about the environment increased, there was a gradual transition from such utilitarian approaches to a more general protection of endangered species. The prohibition, temporary or permanent, on taking and killing was supplemented by the protection of habitats, allowing the species to feed, rest and reproduce.
Many of the first-generation MEAs were concerned with the marine environment. Examples include the 1954 International Convention for the Prevention of Pollution of the Sea by Oil (OILPOL), 1972 Convention on the Prevention of Marine Pollution by Dumping of Wastes and other Matter, the 1973 International Convention for the Prevention of Pollution from Ships (MARPOL) and the 1982 UN Convention on the Law of the Sea (UNCLOS), which sets out the principles for dealing with threats to the marine environment and the biological resources of the sea. Many MEAs were also adopted for the protection of regional seas. Thirteen regional Action Plans and nine Regional Seas Conventions and their protocols today make up a web of detailed obligations for the majority of coastal states (Kiss and Shelton 1991, Sands 1995).
The UN Conference on the Human Environment held in Stockholm in 1972 was one of the first attempts to move away from a sectoral towards a more comprehensive approach including all aspects of environmental protection. This was reflected in the Declaration of the UN Conference on the Human Environment and the Action Plan for the Human Environment, which were adopted in Stockholm.
Environmental agreements drawn up in the lead-up to and aftermath of the Stockholm Conference, however, continued to emphasize conservation rather than addressing the totality of society's interaction with the environment. Examples include the 1971 Convention on Wetlands of International Importance Especially as Waterfowl Habitat (Ramsar Convention), the 1972 Convention concerning the Protection of the World Cultural and Natural Heritage (World Heritage Convention), the 1973 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), and the 1979 Convention on the Conservation of Migratory Species of Wild Animals (CMS) (Johnston 1997, UNEP 1997). These all address biological diversity, and the protection of wild fauna and flora has become one of the most developed areas of international environmental law covered by MEAs. Another sectoral MEA that emerged after Stockholm was the 1979 Convention on Long-range Transboundary Air Pollution (LRTAP), adopted by nearly all European States as well as Canada and the United States.
The second generation of multilateral environmental agreements and legislation is based on a holistic approach under which all species should be exploited either sustainably or not exploited at all, and their habitats protected, extended or improved to make this possible. This second generation was centred on the United Nations Conference on Environment and Development (UNCED), the Earth Summit, held in Rio de Janeiro in 1992. With all but six member states of the UN represented, the conference was a landmark in the history of environmental law, confirming the global character of environmental protection and its integration with development. Two new conventions were opened for signature: the UN Convention on Climate Change (UNFCCC), which is sectoral in that it deals with climate and the atmosphere but widespread in its effects, and the Convention on Biological Diversity (CBD) which seeks to bring together agriculture, forestry, fishery, land use and nature conservation in new ways. UNFCCC and CBD demonstrated the difficulty of pursuing agreements that affect multiple sectors. Both agreements were highly politicized with major diplomatic battles taking place during negotiations. Because holistic, multi-sector agreements involve so many different and cross-cutting areas of law, policy and politics, they can engender more conflict and problems than sectoral MEAs.
The Rio Conference also encouraged the development of other global MEAs (Burhenne and Robinson 1996), including those on Straddling and Highly Migratory Fish Stocks (1995), the Convention to Combat Desertification (CCD, 1994), the agreement on Prior Informed Consent (PIC) on Hazardous Chemicals (1998, see box on the Rotterdam Convention) and new regional MEAs including the Regional Agreement on the Transboundary Movement of Hazardous Wastes in Central America (1992), the Convention on Cooperation for the Protection and Sustainable Use of the Danube River (1994) and the Agreement on Cooperation for the Sustainable Development of the Mekong River Basin (1995).
Special mention must be also be made of a major new convention on Persistent Organic Pollutants (POPs) which is expected to be opened for signature early in the next century. Two meetings of the Negotiating Committee for an International Legally Binding Instrument for Implementing International Action on Certain Persistent Organic Pollutants have been held, and three more are planned before the treaty is opened for signature (POPs 1995).
Most of the global conventions developed since Stockholm are supported by a Conference of the Contracting Parties, a Secretariat and a Scientific Body (see box on page 202).
Non-binding instruments are often forerunners of binding policy instruments and have at times had a more profound effect on environmental policy than binding ones. Non-binding instruments have also helped to bring about changes in attitudes and perceptions at all levels of society. While binding instruments receive the bulk of attention from policy makers and the public alike, non-binding instruments have played and are likely to continue to play a major role in the management of global and regional environmental problems.
Non-binding instruments, rather than creating commitments for action in the form of legally-binding targets and timetables, provide a looser framework. In some cases, the main aim is to set out important issues and priorities, foster discussion and attention, and stimulate new thinking and understanding about the relation of humans to the natural world. In other cases, such as the non-binding Prior Informed Consent (PIC) system for chemicals and pesticides, jointly administered by UNEP and FAO, non-binding instruments provide international procedures and arrangements that contributed to the development of a legally-binding regime (Victor and others 1998).
Examples of non-binding instruments include the Global Programme of Action for the Protection of the Marine Environment from Land-Based Activities and the Pan-European Strategy for Biological and Landscape Diversity.
Many non-binding instruments were developed during the run-up to the Rio Conference, some intended for discussion and definition by governments during the Conference. Two important non-binding instruments were adopted during the Conference: the Rio Declaration and Agenda 21 (UN 1993).
The Rio Declaration, consisting of 27 principles, reaffirms the Stockholm Declaration on the Human Environment and builds upon it. Its central concept is sustainable development but it also includes several established and emerging principles, including common but differentiated responsibilities of states, the precautionary principle and the polluter pays principle. Many of the environmental agreements drawn up since the Rio Conference include principles contained in the Rio Declaration which are now becoming part of international law. These include the right of people to an appropriate environment, the right to information, and the right to participate in environmental management. The Rio Declaration has had an important impact on the development of national legislation in all regions, much of which now incorporates some or all of the principles contained in the Declaration, including the right of all people to an appropriate environment and the polluter pays principle.
Agenda 21 is essentially a programme of action covering 40 different sectors and topics. It pays particular attention to national legislation, measures, plans, programmes and standards, and to the use of legal and economic instruments for planning and management. It is probably the most prominent, significant and influential non-binding instrument in the environmental field and has become the guiding document for environmental management in most regions of the world. Its most important impact, through its core concept of sustainable development, has been to extend the environmental debate beyond environmental departments and NGOs. It provides policy makers with a starting point for linking environmental and socio-economic issues. Although there is a long way to go, such linkages have become difficult to ignore. To fulfil the requirements of Agenda 21, most countries have prepared national environmental strategies or action plans and set up institutions for environmental management. Agenda 21 has also had an impact on environmental governance and led to the creation or strengthening of multi-stakeholder organizations in many countries.
Implementation, compliance and effectiveness
While many environmental policy instruments have been put in place in recent years, there is growing concern about their implementation and effectiveness. Implementation, compliance, and effectiveness are separate but linked concepts (see box below). Most policy instruments seek to change the behaviour of target groups - for example, traders of endangered species or emitters of greenhouse gases - leading to an improvement in the state of the environment. Implementation is an activity not only of government - international organizations, trade associations, local governments, NGOs and the general public may all be involved. In practice, society has to deal with a mixture of policy tools: a complex set of legislation that directs command-and-control measures, economic instruments, cleaner production processes, voluntary action by the public and business, etc.
Reporting on the implementation of MEAs generally improves effectiveness by making parties more accountable, diffusing information on successful strategies and methods, helping to direct assistance if needed, and providing information and assessments to guide any future development of the MEAs (Victor and others 1998). States are more likely to comply with the terms of an MEA if they are confident that others are also complying, and transparency provides some deterrence against non-compliance (Chayes and Chayes 1995).
Effective reporting depends on the willingness and capacity of parties to gather and report data accurately and objectively, and well-resourced Secretariats to process this information into accessible formats. The increase in the number of MEAs and non-binding instruments has led to more and more onerous reporting requirements and bureaucratic burdens.
Some of the most highly-developed and effective reporting and review systems are those in MEAs for wildlife conservation The implementation of the Ramsar Convention, for example, is enhanced by a Monitoring Procedure for the specific requirement of maintaining the ecological character of a designated wetland of international importance. A team, generally composed of one Secretariat representative and two international experts, undertakes field visits and office-based discussions with local experts and government representatives. A detailed report, with recommendations for action, is then compiled and submitted to the Government concerned.
