This standard defines environmental and corporate social responsibility performance criteria for computer For the purposes of this standard@ the definition of computer server aligns with ENERGY STAR Program Requirements for Computer Servers 2.11 This standard establishes criteria for multiple levels of environmental leadership and corporate social responsibility performance throughout the product life cycle@ relating to energy efficiency; management of substances; preferable materials use; product packaging; design for repair@ reuse and recycling; product longevity; responsible end-of-life management; and corporate responsibility. Purpose The purpose of this standard for servers is to establish product environmental performance criteria and corporate performance metrics that exemplify environmental leadership and corporate social responsibility in the market. The standard provides a framework and standardized set of performance objectives for manufacturers and the supply chain in the design and manufacture of servers and server components. For purchasers@ this standard provides a consensus-based definition of key environmental and corporate social responsibility attributes and performance metrics@ alleviating individual purchasers from the arduous and complex task of defining environmental and corporate social responsibility performance for servers and server manufacturers. This standard can be used within an established system for the identification of environmentally preferable products by purchasers and to provide market recognition for conforming products and brand manufacturers. This standard is an environmental leadership and corporate social responsibility standard@ defined with the 36 recognition that only leading products@ i.e.@ approximately 25 ?C 35% of the products available in the marketplace@ would be likely to qualify to the base or Bronze level@ and even fewer at the Silver and Gold levels@ at the date of publication of this standard@ although this standard does not limit the number of products that can so qualify. As the environmental performance of products that are available in the marketplace and corporate social responsibility of server manufacturers improves@ it is intended that the criteria will be updated and revised to set a higher performance standard for leadership products. It is intended that this standard will be continually maintained and periodically reviewed to ensure that the definition of environmental leadership and corporate social responsibility@ as reflected in the performance criteria@ progresses with the evolution of technology and services and environmental and corporate social responsibility improvements in the product sector.
