Stake-holders may vary over time and can include regulatory bodies,customers, neighbors, employees, suppliers, etc.3.2.7 sustainability, nAspirational concept denoting thecapacity to meet current needs

17、while maintaining options forfuture generations to meet their needs. To make the concept ofsustainability operational, consistent approaches are requiredthat facilitate comparable, science-based assessments usingmeasurable indicators of environmental, economic, and socialprocesses (1); (2); (3)43.2.

18、7.1 DiscussionConceptual sustainability and sustain-able development goals are described in the Brundtland Report(1987) and other legislation such as the National Environmen-tal Policy Act (US Government 1969) which aimed “to createand maintain conditions under which humans and nature canexist in pr

19、oductive harmony, that permit fulfilling the social,economic and other requirements of present and future gen-erations.” Sustainability does not imply a steady state or anabsolute value, but instead is a relative and comparative termthat must have a defined context, based on clear objectives (4).No

20、aspect of human activity can be “sustainable” everywhereor indefinitely without change or adaptation over time.3.2.8 relative sustainability, na comparison of the sustain-ability of two or more options (products, processes or projects)to enable the understanding of the relative costs, benefits andtr

21、ade-offs that are applicable to defined sustainability goals,objectives and indicators.3.2.8.1 DiscussionAn assessment of relative sustainabilitycan be used to inform decisions leading to more sustainableoutcomes.3.2.8.2 DiscussionAssessing relative sustainability uti-lizes a scientific analysis of

22、economic, social and environmen-tal conditions to enable decisions that will improve thesustainability of a defined product, process or project.4. Discussion of Concepts4.1 It is important to clarify concepts used in this practicebecause they can be used differently in other sustainabilitycertificat

23、ion standards and schemes.4.2 Assessing Relative Sustainability4.2.1 No aspect of human activity can be considered to besustainable indefinitely. Environmental, economic, and socialchange preclude absolute sustainability without adaptationover time. Sustainability is a relative term and reflects cho

24、icesamong options, trade-offs across sustainability aspects(environmental, social, economic), selected criteria, and indi-cator values or trends in a defined place and time (context).4.2.2 Comparison of relative sustainability typically in-volves some combination of past events and conditions as wel

25、las expectations about the future.4.2.3 Because data about the past are limited and knowledgeabout the future is still more uncertain, a process to monitorindicators in a manner than can support continual improvementis a fundamental requirement for this practice.4.3 Context and Stakeholders4.3.1 The

26、 selection of context and stakeholders depends onthe products, processes or projects to be assessed. Contextestablishes the appropriate temporal and spatial boundaries forthe assessment. The context may include the places and timeperiods impacted.4.3.2 The context will be used to identify stakeholde

27、rgroups that can have an interest in the options to be assessed.Stakeholder input is important to help identify and prioritizegoals and criteria for the assessment.4.3.3 Determining the context for assessing the relativesustainability is a critical step. A decision or action that resultsin a more su

28、stainable outcome under one set of conditions maynot produce a more sustainable outcome under other condi-tions. The context and stakeholder priorities are important forselecting the specific indicators used in the evaluation of eachoption and for assessing the relative sustainability.4.4 Continual

29、Improvement4.4.1 Given the definition of sustainability and the fact thatsocial, economic, and environmental conditions are constantlychanging, iterative analysis to support adjustments needed toassure progress toward defined goals is fundamental.4.5 Continual Improvement in Sustainability Assessmen

30、ts4.5.1 Because social, environmental and economic condi-tions are constantly changing, along with the informationavailable to support indicator measurement and technologicaloptions, any effort to support more sustainable outcomesrequires periodic monitoring and reanalysis. This standardpractice req

31、uires the description of mechanisms that willadvance the concept of continual improvement.4.6 More Sustainable Outcomes4.6.1 Recognizing that sustainability is not a state or end-goal, “more sustainable outcomes” underscores that an assess-ment process is limited to identifying what appears to be be

32、tterat achieving specified goals within a defined context and basedon the chosen criteria and indicators. One goal of this standardpractice is to standardize a process for supporting informeddecisions about the relative costs and benefits of options interms of meeting both current needs and unforese

33、eable needsof future generations. Thus, more sustainable outcomes neces-sarily consider the value of conservation and reuse of non-renewable resources.4.7 Science-based Indicators4.7.1 The evaluation of options shall be based on indicatorsthat are relevant, measurable and replicable.4.7.2 This stand

34、ard practice encourages the continued de-velopment of science-based indicators to address the prioritiesidentified by stakeholders. Science-based indicators for someareas of concern are not yet adequately defined in standards.4.7.3 See Appendix X1for examples of science-based mea-surable indicators.

35、4.8 Stakeholders4.8.1 Engaging stakeholders can be challenging due to thebreadth of potential interest groups and the physical, financial,and social-cultural barriers to constructive participation.4.8.2 Sustainability aspects include global and regionalissues such as climate, air, and water.

The United Nations Sustain-able Development Goals (2015) provide one example of suchan effort and it is reasonable for projects to take such thirdpart

37、y processes into consideration when seeking to identifybroad stakeholder interests and priorities.4.8.3 The ability to guide decisions to support more sustain-able outcomes is compromised if an assessment relies ongeneralized data that do not capture priorities and trade-offsinvolved in a specific p

38、roject and context. Information to guidedecisions toward more sustainable outcomes is generated whenassessments focus on a project scale appropriate to support datacollection and analysis for the activities that are causally linkedto locally defined problems and observable values. Stakeholderengagem

39、ent is facilitated by focusing on a similar local scale.4.8.4 Transparent communication is a prerequisite for con-structive stakeholder engagement. Transparency supports thedevelopment of trust among parties and serves as a cornerstonefor sustainability assessment and future monitoring and evalu-ati

41、ment goals, considering trade-offs, identifying sources of information, and supporting ongo-ing work (monitoring) toward continual improvement.5. Summary of Practice5.1 Basic Principles for Assessing Relative Sustainability5.1.1 Several basic principles are to be an integral part of anassessment pla

42、n. Following these principles improves the valueand acceptance of the assessment outcomes.5.1.2 TransparencyIt is essential that the assessment bedocumented with sufficient detailed information such that theprocedure and results are clearly communicated, understood,and can be reproduced by other par

43、ties.5.1.2.1 The expectation of transparency does not stipulatethat all information is made public. There may be situationswhere information could be considered confidential understandard business practices. Confidential business informationis not included under the transparency principle.5.1.3 Stak

44、eholder EngagementThere are two aspects tostakeholder engagement. The first is to identify stakeholdersthat should be considered within the scope and context of theassessment. The second is the outreach to engage the identifiedstakeholders. As the assessment proceeds the stakeholdergroups and engage

45、ment methods can be modified if needed toimprove the input into the assessment plan.5.1.4 Timely CommunicationA system should be in placeto share info on the status of priority indicators for energy orchemical options being assessed. Untimely reporting or de-layed communication with stakeholders can

46、 hamper the effec-tiveness and value of the assessment.5.1.5 Equivalent TreatmentThe goal of a plan to assessrelative sustainability is not to declare something as sustainableor not sustainable but to determine how options compare basedon specific goals and objectives. These plans must be devel-oped

47、 and conducted in a manner that avoids bias. Each optionin the assessment plan shall be evaluated in an equivalentfashion.5.2 Six Steps for Assessing Relative SustainabilityThe sixsteps described below shall be followed when planning andconducting an assessment of relative sustainability. Theseasses

48、sments need to be planned and conducted incorporatingspecific principles to improve the acceptance of the assessmentand prevent bias and market disruption.5.2.1 Step 1: Define the purpose of the assessment plan andthe options to be assessed.5.2.1.1 The assessment plan shall clearly specify: who isin

49、itiating the plan as well as contact information for questionsand general communication about the plan; the project time-line; primary purpose of the plan specified goals relevant tosustainability; and other aspects of the scope and project thatare pertinent for subsequent steps, for example, references tobackground studies and impact assessments.5.2.1.2 The assessment plan description can include otheritems described below related to context, stakeholders, alter-native(s) available to achieve similar goals, etc.5.2.1.3 The plan description can be modified ba
