Resource Manual to Support Application of the Protocol on SEA
Draft Final
A4. SEA of plans and programmes |
Box A4.3: Tiering
The SEA Directive, but not the Protocol, recognizes that plans and programmes may form part of a hierarchy of decisions and that there may be opportunities for savings by sharing information between processes related to these decisions – this is ‘tiering’. (See para. 4.5-4.7 of the EC Guide for further information.) However, the validity of sharing information between decision-making processes within a hierarchy should be examined critically, given that decisions in a hierarchy are usually taken at different times, under differing conditions.
The Protocol, besides a reference to hierarchies in annex III (item 3), does not consider the opportunities of tiering. It may nonetheless be useful to assure that the development of alternative plans and programmes respects the position of the plan or programme in tiered decision-making. Some plans and programmes may include all elements of strategic planning, whereas other plans and programmes may be more limited by related plans and programmes. |
