Conference in Reading is remarkably quiet compared with recent Green Party get-togethers, or perhaps it just seems that way after leaving behind the excitement of the London election. The campaign is snowballing now, and the first full hustings took place on Thursday, hosted by the Green Alliance. You can watch the videos and judge for yourself how we all did on Friction.tv .
Away in Reading, we've been enjoying the international flavour of the conference. The 'Global Voices' panel on Friday afternoon saw the Venezuelan Ambassador to the UK, Samuel Moncada discuss global human and environmental rights with Dr Abdullah Abu Hilal from the Palestinian West Bank town of Abu Dis , a Jerusalem suburb on its way to being officially twinned with my home town of Camden. Also on the panel, talking about the ongoing problems with Shell in the Ogoni region of Nigeria, was human rights lawyer Patrick Okonmah.
Meanwhile, back in London, two new reports have been published that finally demolished the government's paper-thin economic case for expansion at Heathrow. Friends of the Earth have released their paper, “Heathrow expansion – its true costs” . This shows the massive faults in how the consultation documents  value the impacts of expansion. The report shows that, even if you accept the government’s ethically dubious framework that reduces all the impacts of a new runway to amounts of money, the numbers still don’t add up.
The figure used to calculate the cost of climate change damage isn't the Stern Report’s 'business as usual' figure of £53 per tonne of carbon dioxide, but just £19 - a figure that assumes climate change itself will be minimised thanks to strong policies from the government. FoE calls this 'circular reasoning of the worst kind'. Assuming that expanding an airport does count as 'business as usual', correcting this error almost triples the climate costs from £4.8 billion to more than £14 billion, and wipes out the government's 'net benefit' at a stroke.
The FoE report also finds flaws in calculations of the future cost of flights. In particular, the most ridiculous assumption in the whole consultation – that the price of oil “falls from $64 per barrel in 2006 to $53 per barrel in 2030”. I read this and (after I picked myself up off the floor) went to check the oil price today - it was $95.
The second report, published by consultants CE Delft who were commissioned by campaigners HACAN  to look more closely at the figures, is also damning of the government’s economic analysis. They found that gains to business and employment were being similarly inflated by not taking into account the fact that money, if not spent on via the expanded airport, would be spent elsewhere in the local economy.
These studies, exposing the economic con-trick BAA and the government are trying to pull, are important since these supposed benefits are their last positive argument, set against a vast pile of negative consequences of expansion. The population of London are virtually up in arms about the extra noise and air pollution that would result from more flights, and the climate change argument is completely clear – we can’t fight climate change and build more airports, full-stop.
We now have just a few more days until the close of the consultation. Like most such consultations, the questions have been put together in such a way that it’s very difficult to answer them and actually get your opinions across. The campaigners suggest answering all the questions with a simple ‘No’ and I'm urging everyone to do the same before 27th February. See the Stop Heathrow Expansion  website for more on what you can do before then, including coming to the big rally in Westminster on 25th February.
