Tool for identifying environmental 'hot spots' and highlighting key opportunities for effecting environmental improvements. p

Goal: to provide essentially the same results as a full (detailed) LCA – covering the whole life cycle, but in a superficial way (e.g. using qualitative and/or quantitative generic data), followed by a simplified assessment, thus reducing significantly the expenses and time expended.

D.C.A. Pigosso and S. R. Sousa Advances in Cleaner Production 2011 08/15

“It is recognized that where quantification is not possible (for reasons of time or cost, for example), qualitative aspects can - and should - be taken into account (GUINÉE, 2001)”

Designing products with better environmental performance is a necessary action for industries to ensure competitive and environmental advantages. p g However, the systematic incorporation of environmental considerations during product development process (ecodesign) is not an easy task, especially in the early stages, in which there is a lack of information about the product (but the degrees of freedom to take actions for improvements are greater). LCA is a technique developed to study the environmental influence of a product system. But, in some cases, as for complex products, the application of full LCA is hampered by several factors, including lack of data and other

D.C.A. Pigosso and S. R. Sousa Advances in Cleaner Production 2011

  • resources. Time is also a factor that prevents the application of LCA during the

first stages of the product development process (PDP).

In order to overcome the difficulties, it was developed a large amount of ecodesign methods and tools to support the simplified assessment of the life cycle environmental impacts (S-LCA) – 19 presented. A survey on the effective use of these methods and tools by industry should be conducted in future works. Databases development, especially for Brazil, is of great value to facilitate and promote LCA performance for decision-making purposes concerning products. Extreme improvements towards sustainable products can be explored by the
