Dans le système financier et commercial actuel, l'OMC est au cœur des débats, sa politique libérale divisant tant les universitaires que les praticiens sur les formes de gouvernance économique mondiale. Très ouverte à la participation de divers acteurs du commerce mondial, l'OMC a en effet vu la percée lente mais assurée des ONG lors des négociations. Dans le même temps, les intégrations économiques régionales se sont multipliées et leur participation aux négociations de l'OMC s'est accrue, ce qui a conduit à augmenter les interrogations sur les formes de gouvernance étatique économique mondiale. Au sein de l'Organisation, il est un type de regroupement étatique qui a un rôle de plus en plus important, mais dont l'étude reste quasi inexistante : les Groupes d’États, qui reposent sur le respect et la défense de relations équitables. or, l'équité est affichée comme un des objectifs de l'OMC. L'approche constructiviste et de politique juridique permettront d'analyser les modalités et conséquences de l'interaction entre les Groupes et l'Organisation. Cette analyse mettra alors en lumière le degré de contribution des groupes au droit de l'OMC et, dans une plus large mesure, dessinera uen nouvelle acception de l'équité et des formes de gouvernance économique mondiale. / The WTO, which is one of the most criticized international organizations in the world, is currently the focus of debates because of its liberalisms policies. As academics as lawyers wonder how the WTO philosophy can be linked to different forms of international economic governance. Indeed, the number of NGO has grown in the WTO negotiations. In the same time, the number of Regional Economic Integration and their participation to the WTO negotiations increased. As a consequence, interrogations concerning international economic governance rose. At the WTO, a kind of coalitions is particularly remarkable but rarely studied in law: State Coalitions, which are based on the respect and defence of Equity. Similarly, one of the goals of the WTO is to establish Equity in international economic relations. Thanks to constructivism, this thesis highlights the interaction between State coalitions and the WTO. The focus is to point up how important is the contribution of State coalitions to WTO law. As a consequence, this thesis will draw a new meaning of Equity and international economic governance.

Climate change is a critical sustainable development issue with implications for the environment, economies and society as we know it. The problem of climate change is caused by some countries in parts of the world that has a direct effect on people and natural resources in other parts of the world. Climate change is the effect of increased production of Greenhouse gases (GHGs). Due to the vast complexity of the climate change regime the study does not attempt to be comprehensive or conclusive. The aim of the study is to critically evaluate and determine the purpose, enforceability, legal nature, shortcomings and strengths of the non-binding Copenhagen Accord and how the international climate change regime will evolve after the Copenhagen Accord. The study starts with a brief explanation of the international climate change regime and its development, including international environmental law principles, specifically the common but differentiated responsibility principle. The United Nations Framework Convention on Climate Change (UNFCCC) has the ultimate objective to achieve the stabilisation of GHG concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system. The Conference of the Parties (COPs) is the ultimate decision-making and supreme body of the UNFCCC and is authorised to make and implement decisions to promote the implementation of the UNFCCC, it further has the power to adopt new protocols under the UNFCCC and plays a substantial role in the development of new obligations by the parties to the convention. Various COPs, their respective adopted decisions and resolutions which played an important role in the development of the climate change regime are discussed. This includes COP 1 that lead to the Berlin Mandate; COP 3 and the Kyoto Protocol; COP 7 and the Marrakech Accords; COP 11 that marked the entry into force of the Kyoto Protocol; COP 13 and the Bali Action Plan. COP 15 in Copenhagen was internationally expected and intended to be the breakthrough in addressing the post 2012 period. As is evident from the content of this study the result of COP 15 at Copenhagen means different challenges for different countries and the “bottom up” architecture of the accord could help encourage and reinforce national actions. An overview of the effect of the Copenhagen Accord on the climate change regime, with specific reference to COP 16 in Cancun, is then done. The “bottom up” architecture of the Copenhagen Accord was brought into the official UNFCCC process by the Cancun Agreements that were reached at COP 16. The study mostly comprised of a literature study, which reviewed the relevant international environmental law dealing with climate change, taking into account customary international law; international treaties and conventions; government documents, policies and reports; textbooks and academic journals as well as electronic material obtained from various internet sources. / Thesis (LLM (Environmental Law and Governance))--North-West University, Potchefstroom Campus, 2012
