Skanska Sweden is the largest construction company in Sweden, with about 15 000 employees. As part of Skanska’s commitment to sustainability, a strong focus area is adaptation of products and materials used in construction towards resource efficiency and minimization of hazardous chemicals. In order to achieve such a development, a number of changes in the operations of several individual actors in the supply chain, as well as in their interaction with other actors, are required. How has Skanska dealt with the challenge of establishing efficient environmental management in a chain of actors that covers approximately 15 000 suppliers and subcontractors and 60 000 building products? Several means of evaluation and communication have been developed and implemented within the framework of the environmental management systems of Skanska Sweden - in order to ensure that both internal and external environmental requirements are communicated and followed up efficiently throughout the supply chain. 2. SUPPLIER EVALUATION AND COMMUNICATION The purchasing function and Skanska Sweden’s main suppliers is of crucial importance in order to ensure success in achieving the overall environmental ambitions of Skanska Sweden. Skanska Sweden thus promotes development of environmental management of our main suppliers including environmental product development and eco-labelling. It is also of importance to secure a high minimum level of environmental performance from suppliers that are identified as critical from an environmental perspective in certain selected projects. In order to communicate the environmental requirements on suppliers and products to the suppliers, a web site called Miljöwebben, “The Environmental Web” (http://www.inkop- miljo.skanska.se) has been established by Skanska Sweden. The purpose of the web site is to serve as a tool for management of environmental supplier evaluations. The supplier evaluations are used to ensure that the suppliers of Skanska Sweden are aware of and comply with legal requirements as well as Skanska Sweden’s minimum requirements on suppliers and their products. In addition, by giving suppliers an opportunity to comply with requirements beyond minimum requirements, and hence market themselves in terms of environmental aspects, the intention is to stimulate suppliers to develop environmental management and provide incentives for environmental excellence among our main suppliers. The result of the environmental supplier evaluation is then integrated into the total supplier evaluation performed by the purchasers, which also takes into consideration parameters such as economy, quality, time, technology and level of co-operation. As a result of the environmental supplier evaluation, the supplier will be placed in one of four categories of suppliers: Not Approved (level 0), Approved (level 1), Good (level 2), and Very Good (level 3). The questionnaire that is the basis of the evaluation is divided into three parts, of which all the requirements of the first part need to be met by the supplier in order to be approved. The requirements of the first part mainly aims to secure compliance with environmental and occupational health legislation, and that the supplier complies with minimum Skanska requirements such as at-source waste separation at project sites, that products sold do not contain restricted substances and that the supplier will identify products that contain hazardous substances that Skanska has decided to phase-out. To become a supplier evaluated as Good, all the requirements of the second part of the questionnaire have to be fulfilled. These requirements entail for example that suppliers must work according to established environmental policy, targets and programs, which are followed up by documented internal audits. It is also required that environmental information in the form of Building Product Declarations is supplied for delivered products. To become rated as Very Good, for example means that the supplier needs to have implemented a certified environmental management system, that the supplier has in-house environmental specialists as well as reference projects with high environmental profile, and that the supplier provides products that fulfil criteria of environmental labelling where applicable. The supplier answers the questionnaire on-line. The evaluation is later performed by an editor of the web-site, which is associated with the Environmental Unit of Skanska Teknik. The result is then communicated to the purchaser at Skanska that is the contact of the supplier. If requirements are not met, the purchaser has to support the supplier to improve in order to continue to co-operate. Otherwise, an alternative supplier has to be identified. The supplier can at anytime enter the web-site using his unique user name and pass word, and update his questionnaire. The supplier is able to view the result of the evaluation of his company, but not of the competitors. The latter information is only available when logged on as a Skanska employee. The Environmental Web makes it possible to communicate general requirements and principles to a larger number of suppliers, as well as giving them an entry to ask questions regarding the requirements. At present, more than 700 prioritised suppliers have been evaluated through the Environmental Web, of which approximately 80% has been graded as Approved, 10 % Good and 1% Very Good suppliers. The information provided on the Web by the suppliers, is then used as a basis for a discussion of the suppliers’ environmental performance held in the regular follow-up meetings held between Skanska purchasers and the suppliers. 3. PRODUCT EVALUATION AND COMMUNICATION The Skanska in Sweden Product Evaluation Method has a strong focus on contents of hazardous substances in chemical products and other building products used in construction. The basis of the Evaluation method is the chemical substances lists, consisting of the List of Restricted Substances, the List of Phase-out Substances, and the Surveillance List. Further, the method also includes criteria for recommended products. The List of Restricted Substances (“Förbudslistan”) is based on the Skanska Group list of five globally restricted substances, which for Skanska in Sweden has been extended to cover 15 groups of substances that are not allowed to be present in products purchased by Skanska in Sweden or any of its subcontractors. The restricted substances are primarily examples of substances which use is not in compliance with Skanska environmental policy or Swedish and international legislation. The Skanska in Sweden List of Phase-out Substances (“Avvecklingslistan”) is a list of 24 substances, or groups of substances, that are to be phased out from products purchased in the Swedish Skanska companies. The selection of substances is based on an analysis of which substances that are to be phased out on a short-term basis due to their especially harmful environmental and health characteristics, and their relevance to the building sector in terms of volumes used. Also this list could be seen to constitute a list of examples of substances that are to be phased out, as the intention is not to replace them with not mentioned alternatives which possess the same negative characteristics. Skanska Sweden has established an environmental target associated with the chemical lists, which entails that by the end of the year 2004 no phase out substances should be present in purchased products. An exception is made for brominated flame retardants, which has been selected as a priority issue and which should therefore be phased out by the end of year 2002. For products covered by central and regional purchasing agreements, the time table is more strict, and the target is set such that no substances on the phase out list should be present in products through central agreements by the end of year 2002. Other examples of substances present on the phase out list are phthalates, cadmium, mercury, lead, chlorinated paraffines and nonylphenoletoxylates. The Surveillance List (“Bevakningslistan”) is a selection of substances that is given special attention due to their negative characteristics from an environmental and health perspective, but are for different reasons not currently selected for phase-out. Still, it is considered preferable to choose a product that does not contain any substances on the surveillance list than one that does. In order to enable all parts of the organisation to comply with the product requirements and to be able to select products that do not contain phase out substances, two database tools have been developed: “The Chemical Database” (Kemdatabasen) and “The Environmental Database for Building Products” (Miljödatabas Byggvaror). The Chemical Database is available on the intranet and consists of more than 5000 evaluated chemical products used in Skanska in Sweden and their Material Safety Data Sheets (MSDS). Only products that have been subject
