The 'POLLUTER PAYS PRINCIPLE' in international environmental law was endorsed in:

1. Rio Declaration 1992, Principle 16: 'National authorities should endeavour to promote the internalization of environmental costs and the use of economic instruments, taking into account the approach that the polluter should, in principle, bear the cost of pollution, with due regard to the public interest and without distorting international trade and investment.' 2. The POLLUTER PAYS PRINCIPLE assigns the financial responsibility for pollution prevention and remediation to the polluter. 3. Originally developed in OECD recommendations (1972). 4. Adopted as customary international law by the Indian Supreme Court in Indian Council for Enviro-Legal Action v. Union of India, (1996) 3 SCC 212 (Bichhri case). 5. Hence option B is correct. _Source: UN Charter 1945 / Vienna Convention on Law of Treaties 1969 / Geneva Conventions 1949 / ICJ Statute / UDHR ICCPR ICESCR — Rio Declaration on Environment and Development 1992, Principle 16_
