With reference to ‘Global Environment Facility’, which of the following statements is/are correct?

The correct answer is A. The Global Environment Facility was set up in 1991 as a pilot and restructured in 1994 to provide grants and concessional funds to developing countries for global environmental benefits. It serves as the financial mechanism for the Convention on Biological Diversity and the UNFCCC, and also for the UNCCD and the Stockholm Convention on Persistent Organic Pollutants. It funds projects; it does not do the research itself.

Why the others fail:

• Statement B is wrong. GEF does not conduct scientific research. Environmental science at the global level is done by bodies such as the IPCC or national institutions.
• Statement C is wrong on two counts. GEF is not an OECD agency; it is an independent entity with its own Council and Assembly, implemented through agencies such as UNDP, UNEP and the World Bank. Its mandate is funding for global environmental benefits, not general technology transfer.
• Option D fails because B is incorrect.

Core concept: financing of global commons and the idea of incremental cost for developing countries under common but differentiated responsibilities. For Mains GS-III, this links to climate finance debates, including the Green Climate Fund and whether developed countries meet their finance commitments.

Trap: candidates see 'environment' and 'transfer of technology' and tick C, or assume a financial mechanism must sit inside an OECD or UN agency. Remember that GEF's role is funding, and it was created outside the OECD structure.
