This book, titled environment, energy and Climate change covers cases and material in environmental law and topics related to energy and Climate change, broadly based on the syllabus prescribed by bci. It includes the important legal provisions, case-law and some recent developments. This book, unlike a typical reference-book has been written in an elementary manner with detailed summaries of case-law highlighting the facts, issues, contentions and order. The book covers the principles of international environmental law, international jurisprudence, relevant constitutional provisions, principles and case-law and the cases and material on law relating to water, air, forests, animals and biological diversity. The book includes discussion on climate change, sustainable development goals (SDGs) and National Green Tribunal (NDT) with summaries of important not orders. The book presents a relatively novel approach and would be useful for students interested in environment, energy and Climate change. Lecturers, researchers and practitioners may also find it useful. The simple approach may also interest students who are yet to enroll in law schools, as environmental Studies and Environmental Science are being widely taught even in schools.
