13、 for the concepts, techniques, toolsand methodologies that can be used to support decisions surrounding thesustainable use of materials.Sustainable development is defined by BS 8900:2006 as “an enduring, balancedapproach to economic activity, environmental responsibility and social progress”.Materia
14、ls are an essential part of everyday life and the use of materialscontributes to the quality of living standards: the houses that we live in, thefood that we eat, the vehicles in which we travel and the way we communicate.NOTE For the purposes of this British Standard, the terms “materials”, “compon
15、ents”and “products” are interchangeable, depending on where the user is in the supplychain and on the stage of the life cycle. In essence, a material is an input that isprocessed is some way, a component is an input that is assembled, and a product isthe output. The product of one part of the supply
16、 chain can become a material orcomponent of the next.An expanding global population and increasing social need for an improvedquality of life will create even higher demands on raw materials and naturalresources. This framework recognizes that current levels of resourceconsumption related to materia
17、ls exceed that which can be replaced by naturalmeans, and as a consequence absolute sustainability is not currently attainable.This document sets out a framework to guide decision making in the sustainableuse of materials in relative terms.The sustainable use of materials seeks to attain positive so
18、cial, environmentaland economic contributions and to minimize negative impacts. The social,environmental and economic aspects form the basis of any sustainabilityassessment.It is important to note that the evaluation of the three aspects can be subjectiveand will require the consideration of a numbe
19、r of stakeholder views. This willaffect the complexity of the decision-making process, but will help to avoiddecisions being taken on the basis of narrow or short-term views that could leadto undesirable consequences when considered in a broader and longer-termcontext.A number of reference sources a

Theframework can be applied to all parts of the supply chain and is intend
