The Danish Minister for the Environment, Kirsten Brosbøl, is impressed that several of the world's biggest container carriers - including Maersk and Norwegian Wallenius Wilhelmsen Logistics - are planning to meet next week in Copenhagen to discuss a new environmental alliance. The alliance, named the "Trident Alliance, is aimed at finding a way to handle the coming sulphur emission regulations and, not least, the lack of control in this regard, which several carriers fear will create an incentive for fraud.
