                 labour, material, social and environmental costs). This amounts to ambivalence by policy
                 makers and governments. Given this situation, it is perhaps unsurprising that research suggests
                 consumers are not convinced of the importance of their contribution, and mainly expect leg-
                 islation to be set by public authorities first (Zaccaï 2008). This may imply an aversion to being
                 in the minority of ‘payers’ (environmental product purchasers) while the majority remain as
                 free riders who get cheap goods, and meanwhile everyone pays the consequences through
                 climate change and other impacts.
                    Short term economic and political perspectives also give businesses a false indication that
                 long-term environmental risk assessment, LCA, product stewardship and corporate social
                 responsibility are not important. The net result is that a lack of good regulation to guide pur-
                 chasers and businesses in responding to environmental concerns is a significant factor in pre-
                 venting demand for environmental purchasing, and also presents a barrier to the uptake of
                 quick LCA in informing both design and purchasing to this end.


                 11.4  Design requirements for quick LCA tools
                 From the preceding analysis of stakeholder needs regarding drivers for eco-design, provision
                 of environmental information and uptake of environmental product purchasing, there is a
                 potential role for quick LCA tools, provided they meet one or more of the following condi-
                 tions; that they:
                    s   assist designers and manufacturers to make early design and manufacturing decisions
                       based on LCA information
                    s   assist environmental managers to control the environmental impacts of organisations
                       by providing quick LCA information to help them meet environmental objectives and
                       targets
                    s   provide information in clear, simple, accessible ways for use by consumers, purchasers
                       or specifiers
                    s   engender or contribute to a system of trust and independence in the supply of
                       information about environmental performance
                    s   provide businesses with the means to comply with regulations and codes of environmental
                       performance
                    s   provide policy makers with clear LCA information to inform policy and regulatory
                       development.
                    In meeting such requirements, however, any quick LCA tool must address competing needs
                 for: (a) sophistication in consideration and evaluation of environmental issues, and (b) sim-
                 plicity, ease and speed-of-use by different actors in design, production and/or consumption.
                 Compromise is inevitable with any quick LCA tool. Careful validation is required to provide
                 confidence that LCA results can be replicated with automated quick LCA kits to acceptable
                 levels of accuracy before they will be widely adopted as trusted tools. These competing needs
                 partly explain the wide range of approaches, from simple principles-based ‘checklists’ to
                 spreadsheet or online algorithm-based calculation software programs that provide automated
                 reports. The latter hold out the possibility of more accuracy and ready application, yet may not
                 be transparent enough and are often only applicable to a particular sector or relatively narrow
                 range of design situations.
                    The development and use of quick LCA tools would fast-track the integration of environ-
                 mental design aspects into the product development process (Byggeth and Hochschorner
                 2005). The successful implementation and use of these tools will be guaranteed if they meet a
                 range of requirements (Lofthouse 2006), that:
