Designers have a key role in adapting products to the environment and a sustainable society and many attempts have been made to establish universal DfE guidelines that can be used for these design situations. However, most attempts have failed due to the level of information; too generic makes no sense for the user, and too specific means that the guidelines are too private to be useful for everyone. Furthermore, designers and the acquisition department as well as marketing and production have different background knowledge and different primary tasks. Depending on the complexity and type of product as well as on the cultural background in-different companies and countries, the product development process looks different. It is therefore impossible to establish generic DfE guidelines that are valid for any product in any company. The 10 Golden Rules are a set of generic Design for Environment aspects (first presented by Luttropp (2000)). The "10 Golden Rules" are broad principles, which establish a common basis for a product development team, giving the team members a mutual perspective on the sustainability issue. The 10 Golden Rules are preferably individually customized to be of most use in direct design and product development process. This paper presents the customisation of the 10 Golden Rules at Bombardier Transportation, which is one of the worlds leading companies manufacturing rail vehicles.
