Weighting is more of a political (social, cultural) than a scientific process -- giving, say, more weight to the global warming indicator than to acidification is a values-based decision. Stakeholders may differ significantly on their views about the importance of impacts, as shown in the chart below. - ANSWER-True
Weighted "single score" assessments - ANSWER-Assessments have the advantage of generating one, easy-to-communicate impact number.
The advantage of variable weighting approaches - ANSWER-is that they can be customized to fit an organizations goals and values
Data-driven environmental impact measurements have traditionally been too slow or expensive to acquire. - ANSWER-True
For instance, intuition alone will tell you that a lighter version of a product would save on transportation costs or that a more energy- efficient product would have less of an environmental impact. 1 / 3

Unfortunately, there are plenty of counter-intuitive trade-offs and costs unknown to the average designer. - ANSWER-True
Why you shouldn't listen to public opinions? - ANSWER-PVC has a terrible reputation, even though analysis will show that in certain applications it is the more environmentally responsible choice.

Some companies have created scorecards to enable them - ANSWER-to evaluate a variety of products with at least some internal consistency.
Conceptual Life Cycle Thinking - ANSWER-These approaches consider the life cycle of a product, but tend to have quite qualitative impact evaluations.
One of the most popular tools of this type is the Lifecycle Design Strategies (or LiDS) Wheel, also known as the - ANSWER-Ecodesign Strategies wheel. It was developed as a part of the United Nations Environment Programme by Hans Brezet and Carolien van Hemel Brezet as a way to evaluate how well a product design reflects the application of eight ecodesign strategies, especially relative to alternative designs. 2 / 3

Conceptual Life Cycle Thinking and the Three Choices - ANSWER-1.Impacts - Any, although not always broken out into specifics
- Scope - All life cycle stages
- Metrics - Generally scores
Life Cycle Assessment Abrivation - ANSWER-(LCA)
Life Cycle Assessment - ANSWER-Describes the process of evaluating the environmental impacts of a product at each stage of its life and overall.
Post-Consumer Recycled Abrivation - ANSWER-(PCR)
Post-Consumer Recycled (PCR) Content scores range from - ANSWER- for "unknown or 0-29% post-consumer recycled content" to a maximum of 8 for 100% PCR content.
Such scoring systems try to - ANSWER-reflect the scale of impact somewhat quantitatively, although the direct impact of changes is hard to see. The scorecard's guidelines state that use of PCR leads to resource conservation such as less energy used, less waste produced, and less virgin raw material extracted, but does not say how much. Therefore, it is not easy to tell whether it makes a big or small difference changing from, say, 29% PCR to 30% PCR to get an extra point on the scorecard,
