I did not get the new newsletter, but saw the green giant pad on their site. I would think Germany has different environmental laws than Japan, which dictates the kind materials used. In Germany, and Europe, recyclabilty of a vehicle at the end of life cycle and environmental impacts (during manufacture, during life cycle) are major priorities when manufactoring a vehicle European car makers.
When I first saw the pad, I thought of Zymol and their various country specific waxes, until I thought about this. I am sure few memebers who work in the industry should have the facts and further insight.
