The secretariat of UNCED has estimated the average annual cost (1993-2000) of implementing the activities in Agenda 21 in developing countries to be over US$ 600,000 million, including about US$ 125,000 million on grant or concessional terms from the international community. These are indicative and order-of-magnitude estimates only, and have not been reviewed by governments. Actual costs will depend on, [inter alia], the specific strategies and programmes governments decide upon for implementation.
