OECD/ITF Joint Transport Research Centre Discussion Papers

The International Transport Forum at the OECD is an intergovernmental organisation with 52 member countries. It acts as a strategic think tank for transport policy and organizes an annual summit of ministers. Our work is underpinned by economic research, statistics collection and policy analysis, often undertaken in collaboration with many of the world's leading research figures in academia, business and government. This series of Discussion Papers is intended to disseminate the International Transport Forum’s research findings rapidly among specialists in the field concerned.

Does SEA Change Outcomes?

This paper addresses the advocacy role that SEA can strategically play towards more sustainable and environmental decision-making and how this can be achieved. It discusses the required conditions for this performance and also the frustrations of SEA when such conditions are absent or insufficient. The paper shares the experience with the case of an SEA on the strategic decision on the location of the new international airport in Lisbon, particularly with respect to how SEA made a difference to infrastructure development decisions and the conditions that were met to make it possible.
