The SC ruled that CSR inherently includes environmental protection, in the MK Ranjitsinh & Others v Union of India case, linking CSR obligations to constitutional duties and biodiversity conservation.
Key Observations by the Court

- Corporations as Constitutional Actors: Corporations, as legal persons and key organs of society, are bound by Fundamental duty under Article 51A (g) to protect the environment and wildlife.
- Article 51A (g) mandates to protect and improve the natural environment including forests, lakes, rivers and wildlife, and to have compassion for living creatures.
- CSR is an Obligation, Not Charity: Allocation of CSR funds for environmental protection is a constitutional duty, not a voluntary philanthropic act.
