The secretariat of UNCED has estimated the average total annual cost (1993-2000) of implementing the activities of Agenda 21 in this area to be about US$ 1,900 million from the international community on grant or concessional terms. These are indicative and order-of-magnitude estimates only and have not been reviewed by governments. Actual costs and financial terms, including any that are non-concessional, will depend, [inter alia], on the specific strategies and programmes governments decide upon for implementation.
