The "GREENS" are now really challanging major Political Parties on the Environment.
Ms Lucas said things essential to combat climate change include: the introduction of personal carbon allowances to ensure emissions are shared equally between everyone in the UK; a halt to all road and airport expansion, and incentives to boost renewable electricity generation.
She condemned Britain's record on renewables under Labour, which she said had developed at a "snail's pace" and continued to say "We have the biggest potential for renewable energy within Europe," at a press conference earlier in the day, she added that "We have almost all the wave power and almost half the wind power, yet we are failing."
Siân Berry, the party's "female principal speaker", said earlier today that the Conservatives had yet to sign up to the stronger proposals - including green tax incentives and a moratorium on airport expansion - outlined in the review conducted by John Gummer and Zac Goldsmith.
"There's some nice rhetoric, but in terms of actual policies there is nothing radical and effective there," she said. "And they have already been watered down. John Gummer and Zac Goldsmith have fallen at the first hurdle and backed off on airport expansion. "The energy-saving incentives in the report are meek and certainly not the radical investment we need."
Ms Lucas said: "We are deeply serious about winning elected office but the reason we are serious is because we do not see any evidence that other parties are up for the job," she said. She also siad that "We see a yawning gap between what other parties say and do."
Dr Lucas also added: "You can depend on the other parties to back up their warm words on climate change with a total lack of delivery."
A report published this week by a coalition of nine environmental groups found that "all three [mainstream parties] must close the gap between rhetoric and delivery", said Ms Berry. "They are denying the impact of more flights on Britain's contribution to climate chaos," she said. "They talk about climate change internationally, but at home they do nothing about it."
"The way things are now, being green can be a bit of a luxury. The poorest are being left out of the drive to save the planet."
Ms Berry said that the Lib Dems often failed to match their green intentions with action when they ran local government. She pointed out that the local Liverpool Lib Dem-run council which lagged in the bottom 10 of the local authority recycling league.
To give an idea of whats happening, I refer to this article below written over 18 month ago by John Vidal (with kind permission).
But equally the idea is growing that green ideas suit political opposition better. When your stated intention is not just to achieve power but to totally reform human governance to fit the constraints of the biosphere, then you are not really in the same political ideas field as, say, New Labour or the Greek socialists. Philosophically, you might as well as be Venusians or Martians.
