Project: Environmental law and environmental rights in India

The projectaims to analyze 1/how the central government, the states’ institutions and the local authorities use the law to tackle the growing environmental challenges facing India, 2/ what cultural, social and political drivers shape this legal response, and 3/ how successful Indian environmental lawis in meeting itsassigned objectives. In a first phase, the research will map out the institutional structure and the normative content of Indian environmental law drawing on official sources (constitutional provisions and constitutional case-law, federal statutes, state laws and local regulations). Over a second phase, the research will contemplate the relevance and the feasibility of legal transplants in environmental policy from India to France(e.g. the National Green Tribunal, environmental public interest litigation…) and more generally from the Global South to the West. The project will also evaluate the potential contribution of Indian legal doctrine to the contemporary debate on global environmental governance.
