Various countries in Europe are considering tax schemes to combat the threat of global warming and Europeans have shown their concern by their growing support of the various Green parties. Unfortunately, policy-oriented research on climate warming lags behind North America and governments still seem to display a “wait and see” philosophy. Europe expects a leading role in any global climate convention and, because of its trade links and the uniqueness of the British Commonwealth, has a special role in regard to developing countries. These links are especially important since domestic policies must be coordinated and combined with international agreements in order to be effective.
