Greenwashing
May 16, 2008 by Val Dodge

This is just about the most egregious example of greenwashing I’ve seen. Fifteen per cent less plastic is still 85% too much.
Interestingly, NestlĂ©’s advertising in the U.S. claims that the bottle contains 30% less plastic, which I suppose is an example of greenwashing even more egregious than the Canadian claims.

Eco-Shape? If they really wanted to minimize the use of plastic per unit of volume, they would have made it much more spherical and certainly not turned in on itself.
A sphere is has the best ratio between volume and surface of any container (4/3 pi r^3) : ( 4 pi r^2), which is r : 3. The less spherical a container is, the less efficient it is at containing stuff in its walls.
