ASC achieved ISO 14001 certification in 2004, meaning our environmental management system, GREENTRACK, meets ISO's strict standards. One requirement of ISO is an annual inspection. In the winter of 2005-6, we certified to ISO 14001 (2004) the most current, and stringent, standard. Part of the new requirements are that ASC inform vendors that we have an environmental policy that guides our work. To that end, ASC sent a letter to 500 businesses describing our policy. And we went beyond the requirements, informing vendors that the environmental attributes of their products, and their own company's environmental performance, will factor into our purchasing decisions in the future. As of April 2006, another American ski resort has joined Aspen Skiing Company in ISO certification: Jackson Hole, Wyoming. And other resorts, like Stowe, VT, are moving in that direction.
