Markus Vordermayer-Riemer has published
Non-Regression in International Environmental Law (Intersentia 2020). Here's the abstract:
The book analyses the emerging concept of ‘non-regression’ as a novel legal principle of international environmental law. In order to do so, it traces the development of non-regression in the framework of international human rights law and provides an examination of the respective jurisprudence under universal and regional human rights instruments. These are then compared to closely-related normative concepts in the framework of international environmental law, including the non-regression concepts of the Paris Climate Change Agreement and biodiversity-related agreements such as the Ramsar Convention on Wetlands and the Bonn Convention on Migratory Species. The book advocates a novel usage of comparative law methods in order to allow for fruitful interactions between human rights and international environmental law.
