![]() ![]() Efficiency increases, however, by definition provide only relative improvements. In order to achieve absolute sustainability, effective solutions are required. Arena describes how definitions of relative sustainability may change over time, as newer and cleaner technologies become available. Relative sustainability is a weaker qualifier and may be used to compare two different systems, where one is relatively more sustainable than the other (but does not specify if one or both systems are sustainable in an absolute sense). As stated above, absolute sustainability can only exist for a predefined period of time. relative sustainability, effectiveness vs. Synergies between ecodesign and other research disciplines exist in theory, but require implementation and testing in practice.Ĭlosely related to the time-dependency of sustainability are the concepts of absolute vs. The number of ecodesign methods and tools available to address them is large, and more reviewing, testing, validation, and categorization of the existing ones is necessary. Barriers and success factors extend beyond the product development team to management, customers, policymakers, and educators. It has evolved from “end-of-pipe” pollution prevention to a more systemic concept, and addresses the complete life cycle. We find that several names for similar concepts exist, with ecodesign being the most popular one. For the qualitative analysis, the findings are grouped according to the research question they address. ![]() Furthermore, most statements originate from Europe, are published in journals, and address barriers and success factors. The quantitative analysis reveals that the number of review articles has been increasing over time. Five research questions on terminology, evolution, barriers and success factors, methods and tools, and synergies, guide the clustering of the resulting 608 statements extracted from the reference. ![]() With the intent of summing up the past research on ecodesign and making it more accessible, we gather findings from 106 existing review articles in this field. ![]()
