The project leading to this compilation of studies has two purposes. The first is to leave a record of the intellectual discussions underpinning the project of a Global Pact for the Environment, with its many sources, views and debates. The second is to contribute to the discussions of the ad hoc open-ended working group established by UN General Assembly A/72/L.51. The report gathers compilations from some of the main authorities in international environmental law from around the World. Each chapter is written in a concise, self-contained and practical manner. The analysis focuses on the different principles and aspects of the Draft Global Pact but it also reviews a range of other materials and topics. Some chapters survey aspects that were not included in the Draft Global Pact.
