Abstract: | Transboundary impact assessment has been carried out for many years but only now is it becomingnormal practice in Europe at the project level. This is occurring because of clear legal frameworks, including bilateral and multilateral agreements, and long experience in finding solutions to the many practical problems. However, many challenges remain, especially (a) in regions with unclear or weak provisions for transboundary impact assessment; and (b) for more strategic decisions for which we have little experience in transboundary impact assessment, notably for policies, plans and programmes likely to have significant transboundary effects and for transboundary activities. |
