The National Green Tribunal (NGT) has suspended the environment clearance (EC) accorded by the Union Ministry of Environment and Forest and Climate Change (MoEF&CC) to the 780-MW Nyam Jang Chhu Hydroelectric Power Project in Arunachal Pradesh. The green tribunal maintained that though it is true that the hydel power project provides eco-friendly renewable source of energy and its development is necessary, it is of the considered view that such development should be “sustainable development” without there being any irretrievable loss to environment.
