  5. Activity Guidelines regarding Responsible Care (Showa Denko, 1995) (1) In the total life cycle of chemical substances, we should make our best effort to review and improve the business activities from the viewpoint of ensuring safety / health and protecting the environment. (2) In the manufacturing activities, we should make best efforts to reduce the burden on the global environment not only by conventional approaches to environmental protection but also by promotion of raw material switching, energy conservation, wastes reduction and recycling, and reduction in the release of chemical substances. (3) In new product development, new business development and establishment / increase / renewal of facilities, we should make ourbest effort to ensure safety / health and protect the environment. (4) We should promote R & D and technology development which will contribute to the improvement of safety / health andprotection of the environment. We should also promote marketing of alternative or new products. (5) We should investigate the influences of the products and materials we handle on Safety / Health / Environment, and encourage ouremployees to have deep knowledge related to safe use and handling, and also provide our customers with such information. (6) In overseas business activities, technology transfer and international trading of chemical products, we should give fullconsideration to ensuring safety / health and protecting the environment. (7) We should comply with the international rules and domestic laws and regulations and make our best effort to cooperate with therelevant international organizations and foreign / domestic administrative agencies. (8) We should positively participate in various activities related to environmental protection and make our best effort tocommunicate with society and communities for better understanding and trust.
