the selection of relevant indicators of environmental performance,.for the purpose of strategic planning, priority setting, product or process design or redesign, identifying opportunities to improve the environmental performance of products at various points in their life cycle,.This is also clear from the introduction to ISO 14040:2006 where all the listed applications of LCA are about improvements: It is therefore obvious that also the ISO 14040 series is concerned with improvements rather than measuring the status-quo. However, the ISO 14040 series is part of the overall ISO 14000 series on Environmental Management Systems (EMS), which has a commitment to continual improvement as a basic requirement for the EMS policy statement. The revision of the ISO 14040 series in 2006 did also not introduce the distinction between “attributional” and “consequential” models, since it was decided to limit this revision to a simple re-writing of the original standards, separating the framework (ISO 14040) from the requirements (ISO 14044) without any intention of changing the actual text and prescriptions of the original standard series. The term “attributional” was not coined until 2001 (on an International Workshop on Electricity Data for Life Cycle Inventories in Cincinnati, 2001.10.23-25) and was not defined before 2011 (in the UNEP/SETAC Shonan Guideline). The first to make this distinction clear was Tillman (in her 1998 key-note lecture “Significance of decision making for LCA methodology” to the 8th Annual Meeting of SETAC- Europe in Bordeaux). The original ISO 14040 series of standards were published in 1997, which was before the distinction between “attributional” and “consequential” models had become clear. The ISO 14040 series of standards on Life Cycle Assessment provide the basic requirements for consequential LCA, even if they do not make a clear distinction between “attributional” and “consequential” modelling.
