In a move to empower American architects to help protect one of the most important ancient forests remaining in North America while decreasing toxic chemicals in our environment, Greenpeace reached out to thousands of design professionals urging them to eliminate the use of old growth temperate rainforest and PVC building materials. Greenpeace wrote to members and staff of the American Institute of Architechts and the National Association of Landscape Architects, asking them to state in their contract specifications and in resolutions from their professional societies that they will not use ancient forest wood or PVC.
