Dopplr
Dopplr, the social network or business travellers, has just announced at ETech a teamup with AMEE. AMEE stands for Avoiding Mass Extinctions Engine and they provide a neutral, open platform for measuring the “Carbon-Footprint” of anything. Dopplr states on their blog that they are still putting finishing touches on the feature, but will be releasing it soon to the public.

I’m not sure if this has anything to do with saving the world from excessive carbon emissions, but at least it should make frequent travellers think of the consequences of their travels. Nevertheless it’s a move to the right direction.
