How about building products that last?
Notebooks made from recycled materials to demonstrate their environmental credentials? How about not handing the notebooks out at all?
Phones made from 50% recycled materials? How about phones that are built to last? That way you don't need to use the 50% non-recycled materials.
Whoops - just realised. Phones that last would mean that people would have less reason to replace their existing handsets, and the notebooks were no doubt an important (environmental) branding exercise.
