The European Union aims to become the world's leader in the fight against global warming and climate change.
But in doing so, it may trigger a green trade war of retaliation and litigation from China, India and other leading carbon polluters in lower-cost Asian economies that refuse to follow the new environmental and energy use standards set by Europe and perhaps soon by the United States as well.
If this were to happen, it would complicate the plans of Australia and New Zealand to make themselves honest brokers between developed and developing countries in the contentious international negotiations on climate change.
It would also undermine the multilateral trading system policed by the World Trade Organisation (WTO) and add momentum to protectionist pressures that already pose a significant challenge to the open international trade regime that has helped bring prosperity to the Asia-Pacific region.
It should be noted that the emissions trading regime currently being considered by the NZ Parliament is far more comprehensive and draconian than that being considered in the EU. The impact on company competitiveness is also likely to be far more severe.
