This conclusion presents some closing thoughts on the key concepts discussed in the preceding chapters of this book. The book conducts a global statistical analysis designed to assess explanations for the emergence of constitutional environmental rights grounded in IR theory, world society theory, and constitutional design theory. It provides an update on the status of constitutional environmental rights in Nepal and Sri Lanka. The book discusses a range of practical steps states can take to construct a robust environmental rights regime. It outlines directions for future research on this evolving subject at the intersection of human rights and the environment. In Nepal, following deadly protests by minority groups who felt the drafting process "backtracked on addressing structural discrimination", the 2007 Interim Constitution was replaced by a new constitution on September 20, 2015. In an effort to encourage public participation in the design of constitution, the Sri Lankan prime minister established a Public Representations Committee (PRC) on Constitutional Reforms.
