All targets of the Waste Prevention and Management Programme are aligned to, and are consistent with, the national objectives for the National Development Plan and the National Environment and Resources Management Programme, and they are all derived from the Waste Law. Indicators included In the National Environment and Resources Management Programme were developed by SEMARNAT staff, together with Japanese international co-operation agency (JICA) experts, and were aimed at assessing the effects of implementation of the programme. Waste management targets are generally qualitative in nature, although quantitative targets exist in other environmental management areas such as energy and water policies.
