New Sony Ericsson phone looks to have better environmental credentials

The Guardian reported last week that "Sony Ericsson will unveil two "green" handsets tomorrow with a carbon footprint 15% lower than current models."
This model looks pretty snazzy to me and I like Sony Ericsson mobiles so all good to them.
Reading the article shows a lot of "improvements" are packaging based which is all good but doesn't deserve too big a slap on the back in my opinion.
