The MoEF supervises all import and export-related activities that can have an impact on the environment, for example, import/export of hazardous wastes for which prior approval must be obtained from the MoEF. The MoEF is also the main agency for the negotiation/implementation of multilateral environmental agreements. The MoEF's website is an excellent source of copies of domestic environmental laws and information on India's position on international environmental matters.
