It was prepared jointly by Technical Committees MI/1, MaterialsIndustries, and SDS/1, Sustainable development co-ordination.

It should not be quoted as if it were a specification or a codeof practice and claims of compliance cannot be made to it.Presentational conventionsThe provisions in this standard are presented in roman

11、(i.e. upright) type. Itsrecommendations are expressed in sentences in which the principal auxiliaryverb is “should”.Commentary, explanation and general informative material is presented insmaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis public

12、ation does not purport to include all the necessary provisions of acontract. Users are responsible for its correct application.Compliance with a British Standard cannot confer immunity from legalobligations.BRITISH STANDARDBS 8905:2011ii BSI 2011IntroductionThis British Standard provides a framework

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

20、re included to support the evaluation of thethree aspects of sustainability.1 ScopeThis British Standard provides a framework for the assessment of social,economic and environmental issues in the sustainable use of materials. Theframework can be applied to all parts of the supply chain and is intend

21、ed tosupport decision making about the sustainable use of any type of material.This standard covers consideration of:a) the social, economic and environmental aspects throughout the materiallifecycle, covering:1) sourcing of materials;2) conversion of materials into products;3) performance of a prod

22、uct over its functional lifetime;4) end of life of the product and either the reuse, remanufacture,recycling or disposal of the product; and5) end of life of a material and either the reuse, remanufacture, recyclingor disposal of the material,BRITISH STANDARD BS 8905:2011 BSI 2011 1with particular e

23、mphasis on social performance in the use phase of aproduct life and environmental performance over the full life cycle, andtaking into consideration the longer term and local economic issues;b) how to balance these aspects against stakeholder priorities in terms ofsustainable development;c) guidance

24、 on the use of decision support tools to assess the relativesustainability of material choice; andd) the importance of data quality when carrying out a sustainabilityassessment.NOTE This standard assumes that the project brief and material design options havebeen agreed prior to the use of the asses

25、sment framework.The standard does not provide:i) comparisons between specific materials;ii) advice on the properties of materials and products; oriii) recommendations on specific software tools to support the evaluation andcomparisons of social, economic and environmental aspects.2 Terms and definit

28、 basis. When a product orcomponent comes to the end of its useful life it does not necessarily mean that thematerials it is composed of are at the end of their useful life. The sustainabilityassessment ought to take account of this.NOTE 2 In sustainability terms design for end-of-life is important b

Sustainability requires a balanced decision-ma

These three aspects of sustainabilityshould be considered to be interdependent because a change in one aspect canimpact on another. For example, trying to achieve an environmentalimproveme

40、nt, such as reduced emissions of greenhouse gases, might also havean economic implication in regions where emissions trading has beenintroduced. When considering sustainable development, the benefits potentiallyattained through any improvements have to be weighted against the potentiallynegative imp

41、acts that could be caused by the consequences of making thatimprovement. This is assessed by carrying out a full sustainability assessment,and needs to be based upon life cycle thinking and provide information onbenefits set against impacts.BRITISH STANDARDBS 8905:20114 BSI 20114 Framework for a sus

Care should be taken to ensurethat the transparency of any exclusions are considered in data collection andverification.As a s

47、ustainability assessment can only be relative, a reference or base caseshould be defined for comparison with the alternative solutions to assesswhether each alternative is more or less sustainable than a base case (e.g. anexisting product, a benchmark or an aspirational goal).Figure 1 illustrates th

48、e phases of an effective sustainability assessment andAnnex D (Figure D.1) demonstrates how comparative assessments of materialchoice may be conducted.BRITISH STANDARD BS 8905:2011 BSI 2011 5Figure 1 The sustainability assessment process for a materialKeyOptionalBRITISH STANDARDBS 8905:20116 BSI 201

49、15 Phase 1: Scoping (see Figure 2)5.1 Setting the aims, objective and scope of the sustainabilityassessmentIt is critical to define the scope of the assessment and to check that this isaligned with the original aims. Scoping defines what is and what is not to beincluded in the assessment, and the user needs to check that the scopingdefinitions at each stage remain relevant and are sufficiently inclusive to achievethe desired aims and objectives. Without a well-drafted scope it is impossible tomake a worthwhile comparative asse
