An Iterative Process
SEA, by its nature, is not a one-way process. In the course of the SEA, certain steps might have to be proceeded iteratively to ensure environmentally unfriendly components are discarded and environmentally friendly components are brought forward to the next round of evaluations. Because of this nature, both the SEA process and its assessment results are equally important. SEA processes allow project proponents or decision makers to have a better and more thorough understanding of the objectives of their PPPs and the consequential environmental implications. When evaluating various considerations or factors, project proponents or decision makers always have opportunities to shift their mindsets and in turn change the objectives of the PPPs, with a view enhancing environmental performance. Both SEA processes and results are important in achieving environmental sustainability outcomes.
