Sustainable Minds, an MCADCafe content partner, is an on-demand green product design software and information services company that integrates deep knowledge of product design, life cycle assessment and environmental systems design to help product design teams create more sustainable products.
One of the general criticisms about standards is that they are almost always out of date - those leading technical innovation are usually guessing where things are going and hoping they make the right bet.
Given the increasing awareness and focus on sustainability and minimizing the overall environmental impact of products across their entire lifecycle, is there a useful role for standards?
The folks involved with the creation of the International Electrotechnical Commission's draft standard for Environmentally Conscious Design (ECD) for Electrical and Electronic Products and Systems (IEC 62430) would answer, "absolutely!"
The new standard, which was released in draft form for final review March 21st (review period ends September 5th) was initiated by the delegation from Japan, but developed with the participation of technical experts from 26 additional countries.
In a nutshell, the standard promotes ‘life cycle thinking' (LCT), which is defined as the ‘consideration of all relevant environmental aspects during the entire life cycle of products and systems.' The key elements of LCT are:
· Determining to minimize the overall adverse environmental impact of the product;
· Identifying and quantifying the significant environmental aspects of the product;
· Considering the trade-offs between environmental aspects and life cycle stages.
The standard also goes on to define how an Environmentally Conscious Design Process (ECD Process) can be implemented, including processes, supporting data requirements, and the role of systems for analysis/evaluation and control, across all lifecycle phases. The figure below from the draft standard provides a great graphical overview of the elements and inter-relations that make up the ECD process.

Fundamental to the approach is that it is considered an iterative process, providing the information and historical record to understand and track environmental performance over subsequent product generations, and potentially to provide comparison to competitive products.
I believe that this draft standard has real value and is definitely worth evaluating. Unlike some technical standards that are always behind (e.g. IEEE 802.11- how many of you have bought a ‘draft n' device?), IEC 62430 defines a very useful framework for sustainable product development. In my judgment, it has the potential to foster standard practices for lifecycle assessments that will allow end users to make informed purchase decisions. Ultimately, that rewards the producers who are working to make a real difference in sustainability. Further, I believe that the methodology and framework are applicable and of value to other
industry verticals beyond the electronics industry.
The IEC 62430 is still in review, so you will have to wait a few more months to read it (unless you are part of the review process!). I'll keep you informed via this blog - stay tuned to see how it plays out...
