Although multilateral agreements on the protection of environmental goods have been in place for more than a century, the development of multilateral environmental agreements (MEAs), as we know them, in the 21st century, is a recent phenomenon that dates back about four to five decades. The selection in this bibliography focuses on global MEAS. They contain references to the literature on regional ACCORDS in areas where such contracts are particularly important. There is no generally accepted definition of MEAS. This bibliography is based on a fairly broad definition, including contracts to protect the environment at least in part. Some areas of international law have been the subject of in-depth discussions with respect to ME. The literature on the relationship between HUMAN RIGHTS and human rights, trade and investment has been included in the following sections. The United Nations Environment Programme is the main UN environmental body and has begun negotiations on basic MMAs. In addition, many specialized agencies and other United Nations agencies have taken the initiative to host the institutional structures created by the United Nations.

The following sections are not categorized according to the institutional affiliation of the MEA. Nor do they specifically focus on international environmental law (IEL). But there are strong links between customary law and MEA. For example, considerable efforts have been made to codify the usual EIF in some areas, including state responsibility and the obligation to cooperate in the prevention of environmental damage. The main elements of the usual EYI fall within the scope of this bibliography. MEAs can be described, studied and analyzed from a wide range. The main perspective of this bibliography is international law. In addition, significant contributions from other social sciences, including political science, were mentioned. Given the fragmentation of IEL and the many MEAs, we can only contain a few references for each topic. Therefore, the following quotations concern almost exclusively monographs and published books. Articles or publications written by conventional bodies, host bodies, non-governmental organizations or states are mentioned only in exceptional cases.

Since iEL is a young area of law, material and procedural provisions are still evolving in many areas.
