Something which is not widely documented, is the influnce that really small decisions can have on sustainability outcomes.
Whilst doing the Refillable Packaging Systems project with Boots and DEFRA it became really clear that if delivered well, refillable packaging systems had huge potential for reducing sustainability impacts and delighting the customer. However if delivered badly they could lead to more waste and thoroughly irritate the customer. The key was to identifying and getting the important things right.
This leads to the though that the key to actually achieving sustainability improvements is too look to the detail. One well selected, small issue delivered well can dramatically improve the sustainability performance of the products we design.
