It is essential to develop techniques in order to make informed decisions, but in a commercial world probably the best approach is to adopt a broad set of criteria that are
likely to give environmental benefits both to the business, the consumer and broader society. This may well be difficult, particularly given that many of the benefits of green supply chains, such as decreased pollution, increase water quality or decreased
production of GHGs are not effectively quantified in an economic way in the
marketplace. Thus, in many ways the best way forward may be to adopt some broad form of accreditation such as organic or to develop individually branded supply chains
that will give an unique selling point for the event or the event caterer.
