So it has come in one of our other threads, talks of our responsibility as designers to guide clients about sustainable options. Now, my girlfriend is a product designer, and they drum the sustainability argument into them from the moment they walk through the door. In fact most of the high graded pieces from her final show were effective ideas pushed into a sustainable medium. Example, one girl made a lunch box made out of light weight re-enforced glass! Sounds ridiculous, but in principal it worked! The science was sooooooo complicated it was boring, but it did work. My girlfriend's dissertation was also about sustainability in design. So I might get a little OTT on this topic. This discussion was started because of plastic credit cards, plastic is not as bad as it used to be, whilst not totally sustainable, easily downcycled and recycled. Wonderful example: innocent drinks : all about us They used to use bio plastics, but found them unsustainable in the grand scheme, production, manufacture.... The other favourite argument on the subject of sustainability is the scrapage scheme and the toyota prius. I going to avoid example here and just generalise, 80% of a cars overall emissions are created in the manufacturing process, so the idea of destroying an easily repaired car to buy a brand new electric car is a joke! The best way to make cars more sustainable is to keep them on the road longer and convert them to lpg, bio fuels etc. Right I have started a major rant here, please someone else get involved before this turns into "Michael's Big Sustainability Speech".
