India is devoted to a clean environment with clean air and water. Indian constitution also supports environmental protection. India's commitments and obligations to environmental conservation and protection within the scope of the Sustainable Development Goals (SDGs) are manifested in the fact that several administrative and regulatory measures, including a separate statute on air and water pollution, have been enacted. However, with its expanding population and pervasive poverty, India has great problems in reaching its several other key goals related to poverty and hunger elimination.
