38.11. In order to enhance and rationalize the intergovernmental decision-making capacity for integration of environment and development issues and to ensure effective follow up to UNCED and the implementation of Agenda 21, provision shall be made within the framework of the General Assembly and the Economic and Social Council. This should provide for active involvement from organs, programmes and organizations of the United Nations system, Governments and non-governmental organizations including industry, business and scientific communities. It could take the form of either: - a high-level Commission on Sustainable Development as the main subsidiary organ of the General Assembly and the ECOSOC for the integration of environment and development issues that will report directly to the General Assembly on matters of substance and through ECOSOC to the General Assembly on matters related to coordination. It would consist of States elected as members of this Commission; or - The full use of a revitalized ECOSOC, in accordance with General Assembly resolution 45/264, with a recommendation for either the establishment of a subsidiary mechanism such as, in particular, a third sessional committee, or the full utilization of its new high level and coordination segments. On the basis of the conclusions of UNCED, the 47th session of the General Assembly should determine specific modalities for the work and other organizational aspects of institutional arrangements agreed at the Conference, in conjunction with a review of the complementarity between the role of ECOSOC and the General Assembly in accordance with General Assembly resolution 45/264. In this respect, the Secretary-General is requested to prepare a report with appropriate recommendations taking into account institutional objectives and functions decided by UNCED.
