The main instruments available under international law for countries to collaborate on a broad range of global environmental challenges are international conventions and treaties on environment and natural resources also known as Multilateral Environmental Agreements (MEAs). These have been defined as agreements between states which may take the form of “soft-law”, setting out non legally-binding principles which parties are obligated to consider when taking actions to address a particular environmental issue, or “hard-law” which specify legally-binding actions to be undertaken toward an environmental objective.
MEAs have also been defined as international agreements that are intended to promote international cooperation to address global environmental challenges that the world is facing today such as climate change, biodiversity loss, pollution and waste. MEAs are based on the understanding that, just as the causes and the consequences of environmental issues are global in nature, so too must be the solutions. They intend to foster global cooperation in addressing environmental challenges. It has been pointed out that MEAs are negotiated and agreed upon by member states of the United Nations at the international level, and each country is responsible for implementing such agreements at the national level.
In addition, it has been asserted that MEAs have similar features to other international treaties. However, they are also different in that they are intergovernmental documents whose main objective is to prevent or manage human impact on the environment and natural resources. As a result, MEAs are legally binding to countries that participate in them through ratification or accession, as well as to those who accept them through signing since that in itself assumes an “official agreement” between the States via the MEAs. It has been contended that since MEAs are not merely declarations of intent but tools of international law, they are viewed as ideal and effective means of implementing policies whose objective is environmental protection and Sustainable Development.
MEAs have been identified as vital in addressing the most pressing environmental issues of global or regional concern and are critical instruments of international environmental governance and international environmental law. They cover a wide scope of issues, ranging from the protection of the atmosphere to the sustainable management of chemicals and waste, to halting nature and biodiversity loss. Amongst the global environmental issues that MEAs are designed to respond to include: loss of biological diversity, adverse impacts of climate change, depletion of the ozone layer, hazardous waste, organic pollutants, marine pollution, trade in endangered species, destruction of wetlands among others.
Among the key MEAS is the United Nations Framework Convention on Climate Change (UNFCCC) which is an MEA geared towards combating climate change by achieving stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system. It entails key principles and commitments by states towards confronting climate change. It has been observed that one of the achievements of the UNFCCC has been to establish a reporting framework which provides information on greenhouse gases emissions and removals using common categorisation and definitions.
Another key MEA is the Montreal Protocol on Substances that Deplete the Ozone Layer. The Protocol sets out a global determination by states to protect the ozone layer by taking precautionary measures to control equitably total global emissions of substances that deplete it, with the ultimate objective of their elimination on the basis of developments in scientific knowledge, taking into account technical and economic considerations. The Montreal Protocol has been identified as a landmark MEA that regulates the production and consumption of nearly 100 human-made chemicals referred to as ozone depleting substances46. It has been hailed as one of the rare treaties to achieve universal ratification. With its universal ratification, the protocol has been extremely successful in its original aim of cutting the production and use of chlorofluorocarbons and other ozonedepleting substances. It has been observed that the protocol has succeeded in eliminating nearly 99 percent of ozone-depleting substances.
The Convention on Biological Diversity is another important MEA. The Convention seeks to foster the conservation of biological diversity, the sustainable use of its components and the fair and equitable sharing of the benefits arising out of the utilization of genetic resources, including by appropriate access to genetic resources and by appropriate transfer of relevant technologies, taking into account all rights over those resources and to technologies, and by appropriate funding. It identifies key ways of conserving biodiversity including in-situ and ex-situ conservation. The Convention has had some notable successes including increase in protected areas coverage.
The Convention on Wetlands of International Importance especially as Waterfowl Habitat (Ramsar Convention) is another important MEA that has played a vital role in conserving wetlands. The Convention acknowledges the fundamental ecological functions of wetlands as regulators of water regimes and as habitats supporting a characteristic flora and fauna, especially waterfowl. It requires contracting parties to formulate and implement plans towards promoting the conservation and wise use of the wetlands in in their territory. It has been pointed out that the Ramsar Convention has fostered international cooperation in wetland conservation through actions such as establishing wetland restoration projects.
The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) is another pertinent MEA which seeks to foster international co-operation in the protection of certain species of wild fauna and flora against over-exploitation through international trade. It has been pointed out that as a result of effective implementation of CITES by those who harvest, produce, trade, transport, buy and regulate the wildlife species covered by the Convention, new emergency listings of species have become increasingly rare. Moreover, no CITES-listed species has ever become extinct as a result of trade.
CITES has made significant progress in preventing more species from becoming threatened by trade and enabled the recovery of species that were endangered. It currently regulates international trade in over 40,000 species of plants and animals. It has been argued that CITES can help to reverse the precarious situation of high-value species of wild fauna and flora and ensure a sustainable supply. Most recently, at COP 21, parties to the UNFCCC adopted the Paris Agreement a legally binding international treaty on climate change. Its overarching goal is to strengthen the global response to the threat of climate change, in the context of Sustainable Development and efforts to eradicate poverty through holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels; increasing the ability to adapt to the adverse impacts of climate change and foster climate resilience and low greenhouse gas emissions development, in a manner that does not threaten food production; and making finance flows consistent with a pathway towards low greenhouse gas emissions and climate resilient development.
It has been pointed out that the Paris Agreement has strengthened the global response towards climate change by establishing Nationally Determined Contributions (NDCs) which embody efforts by each country to reduce national emissions and adapt to the impacts of climate change. The Paris Agreement requires each Party to prepare, communicate and maintain successive NDCs that it intends to achieve. It also requires parties to pursue domestic mitigation measures, with the aim of achieving the objectives of such contributions.
From the foregoing it is evident that MEAs have played a fundamental role in addressing global environmental challenges. It has been pointed out that MEAs are central to achieving global environmental commitments towards sustainability. According to UNEP, MEAs have emerged as one of the best ways of institutionalizing intergovernmental cooperation and triggering national action in the environmental sector. In addition to MEAs, environmental multilateralism has been enhanced through institutions, and processes that address environmental concerns at the international level. These include the United Nations Environment Assembly (UNEA), composed of all the United Nations (UN) Member States and tasked with providing overarching policy direction for the global environmental agenda.
UNEA is the world’s highest-level decision-making body for matters related to the environment, with a universal membership of all 193 Member States. It sets the global environmental agenda, provides overarching policy guidance, and defines policy responses to address emerging environmental challenges. It also undertakes policy review, dialogue and the exchange of experiences, sets the strategic guidance on the future direction of the UN Environment Programme (UNEP), and fosters partnerships for achieving environmental goals and resource mobilization.
In addition, UNEP is a body within the United Nations Systems responsible for coordinating international environmental activities and supporting the implementation of treaty commitments. UNEP is tasked with strengthening environmental standards and practices while helping implement environmental obligations at the country, regional and global levels. UNEP’s work is focused on helping countries transition to low-carbon and resource-efficient economies, strengthening environmental governance and law, safeguarding ecosystems, and providing evidence-based data to inform policy decisions. UNEP plays a key role in environmental multilateralism by supporting countries’ efforts in the implementation of MEAs.
The Intergovernmental Panel on Climate Change (IPCC), is a body of the United Nations established to assess the science related to climate change. It prepares comprehensive Assessment Reports about the state of scientific, technical and socioeconomic knowledge on climate change, its impacts and future risks, and options for reducing the rate at which climate change is taking place. The IPCC has had significant accomplishments including its First and Second Assessment Reports, which led to the development of the UNFCCC and the Kyoto Protocol which are key MEAs on climate change. In addition, its Fifth Assessment Report, finalized in October 2014, informed the negotiations and policy formulation towards the Paris Agreement in 2015.
Further, there has been growth of regional environmental agreements to address specific environmental challenges. For example, the East African Community (EAC) has adopted EAC Climate Change Policy which is aimed at contributing to Sustainable Development in the EAC region through harmonized and coordinated regional strategies, programmes and actions to respond to climate change. The Policy identifies several ways of confronting climate change in the region which include establishing a regional framework to guide the harmonization, coordination and implementation of climate change initiatives amongst partner states; identifying priority adaptation and mitigation action areas and roles of partner states and other stakeholders to address climate change in the region; promoting public awareness and socio-economic importance of climate change including; vulnerability, impacts, risks, and response measures in the region and promoting capacity building efforts through inter alia education, training, research, technology development and transfer, information and knowledge management. The policy is therefore a key regional instrument geared towards responding to climate change within the EAC region.
From the foregoing, it is evident that environmental multilateralism has been vital in addressing the most pressing environmental issues of global or regional concern including the triple planetary crisis of climate change, nature and biodiversity loss, and pollution and waste. However, it has been pointed out that environmental multilateralism faces several concerns including implementation of and compliance with the MEAs. In addition, it has been asserted that the inactions of a state or those of others may affect the cooperation chain in environmental multilateralism. It is necessary to (re) invigorate environmental multilateralism in order to enhance sustainability.
