The group of 6 climate pact is worthless

Greenpeace have responded to the 6 nation "climate pact". You can read the press release by clicking here:

152 countries have now ratified the Kyoto Protocol, which contains legally binding emissions cuts for industrialized countries for the period from 2008-2012 (the first commitment period) and negotiations for the second and subsequent commitment begin in earnest later this year in Montreal. This 'pact' looks like yet another attempt by the US and Australia to derail these negotiations and condemn future generations to a world ravaged by climate change.

Indeed, some sort of voluntary scheme is worthless, gas emmissions targets should be compulsory.
