Cutting greenwash is empty posturing anyway but it clearly indicates a
lack of commitment to carbon reduction on the part of the government

"Britain is trying to weaken European proposals to make governments
and companies cut their carbon emissions by 2020 to tackle global
warming, the Guardian has learned. Leaked documents show Britain wants
Brussels to offset more domestic carbon savings through investment in
clean projects in the developing world.

The move would let firms and countries import more carbon credits to
count against their pollution targets. It would allow Europe to make
less effort to cut its pollution, while keeping it on course to meet
an ambitious target of reducing carbon emissions by 20%% by 2020.

The government's own calculations show the proposed change would allow
Europe to emit an extra billion tonnes of CO2 from 2013-2020.

The move was condemned last night by environment campaigners, who
accused the UK of trying to undermine efforts to get European industry
to reduce emissions..."
