Integration of environmental concerns with other social and economic issues must occur at several levels and through a lot of different mechanisms. There is no one mechanism that can solve all the problems. A sustainable development strategy is a mechanism. It's important. Strategic environmental assessment is another very important mechanism, but again, that can be done at different levels, and there are also instruments—such as taxes—that can foster linkages between economic decisions and environmental results. I believe what is needed is a multi-level vision and a number of different tools in order to attain that objective.
