Sustainability (Impact) Assessment- for Assessing and Guiding in Research Magdalena Svanström Associate Professor, Chemical Environmental Science Director, Chalmers Learning Centre
Rational • There is a need for methods that canassess the sustainability of different technologies or options (not onlyenvironmental performance as in life cycleassessments, LCAs) • Sustainabilityassessmentneeds input from different knowledge areas and stakeholders • Sustainabilityassessmentcan guide technologicaldevelopment • Sustainabilityassessmentcan be part of a learning process that improves the assessmentitself and alsobuildscompetence in individuals and organizations (education for sustainabledevelopment, ESD) • With a starting point in LCA methodology, and addingexperiences from ESD work, …
LCA – Life Cycle Assessment • Well-known methodology – international standards • Most suitable for existing technologies with existing data on processes and the larger system
The Life Cycle Environmental Impact Raw material acquisition Transports Emissions Processes Transports Resources Manufacturing Waste Transports Use Waste management
LCA methodology Procedures, System boundaries, Purpose Definition of Goal and Scope Inter-pretation Data on input and output for the system Classification Characterization Valuation ImpactAssessment InventoryAnalysis
Problems? • Normally, LCAs are performed by LCA experts, providingresultsneeded by othergroups • Transparency is often a requirement, but it is still verydifficult to understandifresults are relevant and whattheymean • If you are in earlyphases of technology development, you normallydon’tknowwhat the system looks like and you don’thaveany data • And if you want to address the full range of potential sustainabilityimplications, you need a broaderassessment
Ethanol from corn? A life cycle perspective is important
Sustainability (Impact) Assessment • Someframeworks for broaderassessmentexist – relymostly on an expanded LCA methodology • They almost alwaysrely on predetermined sets of indicators – not on a case-specificdescription of sustainabilitychallenges • Stakeholderinvolvement is oftenlow or non-existent • Results are ofteneven less transparent thanmost LCA studies
Howcanwe make sustainabilityassessmentsomething that: • provides relevant and usefulresults, understandable by all? • can guide technicaldevelopment, also in earlydevelopmentphases? • leads to learning that willbothboost the assessment process and have spin-off effects in parallell and futuredevelopmentefforts? By stakeholderinvolvement and by using the sustainabilityassessment to alsoachieveeducation for sustainabledevelopment (ESD)

Analysis of industry needs of engineering competences in sustainable development- A comparison to the education at Chalmers University of TechnologyMaster Thesis in Industrial Ecology; Andreas Hanning, Anna Priem Abelsson AB Volvo, ABB, Akzo Nobel DHL, Electrolux, E.ON Ericsson, Hifab, Husqvarna IKEA, Scania, Skanska SKF, Sweco, Vattenfall, ÅF Text analysis Text analysis Student questionnaire Focus group Interviews (16 companies) Alumniquestionnaire
Some conclusions: Industry: • Sustainability is not something only for experts • All engineers need a comprehensive basic understanding of sustainability issues. • All engineers need a systems perspective, not only those working directly with sustainability issues. • All engineers should be aware of the underlying reasons as to why sustainability issues are important in the business world. Students: • This is prioritized and understood best by students that have SD embedded into their programs, not only single separate courses • Especially, the (company) economic (and social) perspective of sustainability is lacking
Guidingdevelopment in research usingsustainabilityassessment – methodology under development • Different stakeholders need to be involved in selecting indicators, in providing input and in interpreting results • All communication should focus not only on receiving input but also on achieving learning – important to reach many actors that may influence development

Example: Last resultscommunicated ”No, that is too low, the use of incontinence diapers is much higher!” ”Oh, I thought population was decreasing and therefore also the need for diapers!” ”Good, competition from Asia and Europe is decreasing the need for simple fibre products” ”Hey, this is almost all our forests – and pulp is really only a by-product of timber production!” ”But what happens when we also get an increased need of bioenergy and biomaterials?” ”And what about food production globally? Can we really look at the use of just the Södra forest without considering global demands and trends?”
Some lessons learned • Time – a restrictedresource - discussions and learningtakes time • Make their time feeluseful - alwaysbringsomethinguseful - make sure that there is an exchange of information • Confidentiality – always a problem whencompanies, perhapsevencompetingcompanies, are involved • Company image – companies that have high sustainability ranking are the mostvulnerable • Make sure that you understandcompanygoals, culture, knowledgelevels, earlierexperiences etc.

Kofi Annan, Ghanaian diplomat, seventh secretary-general of the UN, 2001 Nobel Peace Prize “To live is to choose. But to choose well, you must know who you are and what you stand for, where you want to go and why you want to get there.”
BACK-CASTING 1. Criteria for sustainability 2. Today’s situation in relation to these 3. Solutions; futurepossibilities (that fulfill the criteria) 4. Strategies for getting there – steps needed SCENARIO PLANNING 5. Test robustness of solutions and strategies • Identify factors that might be really important for your strategies and solutions • Put in graph: Impact vs Predictability. • Pick the ones with highestimpact - mostpredictableones are trends in all scenarios. Two (unrelated) with lowpredictabilitybecomecriticalfactors. • Describe extremes of the criticalfactors. • Make four scenarios using ”trends” in all and different ”criticalfactor” extremes. • Test your solutions and strategiesagainst the four scenarios - Which work well in all scenarios? Whatcan be changed in order to make the strategies and solutions more robust?
