climate change

The end of the Heathrow stitch up consultation is nigh, so here's another quick reminder that, on Monday, MPs, activists, authors, and, well, all sorts of people opposing Heathrow expansion are holding a mass rally and filling Central Hall in Westminster.

My carbon footprint according to Defra

As I've been winding down my experiments with carbon calculators, I've been noticing more and more just how variable they can be. The results they spit out fluctuate wildly but as they all ask slightly different questions, that's not surprising. What surprises me are the differences between what they claim the CO2 emissions of your average Briton are, and if your trying to figure out whether you're a relatively big emitter or a teeny tiny one, that can be something of a problem.

There's a great opinion piece in today's Independent, in which Johann Hari argues that leaving the fate of planet to consumer choice and voluntary action isn't going to work. His words echo those of George Monbiot and Mark Lynas, and he looks to government to force us all to use less stuff:

In reality, dispersed consumer choices are not going to keep the climate this side of a disastrous temperature rise. The only way that can ever happen is by governments legislating to force us all – green and anti-green – to shift towards cleaner behaviour. Just as the government in the Second World War did not ask people to eat less voluntarily, governments today cannot ask us to burn fewer greenhouse gases voluntarily.

Oooh, this is gorgeous. I know some of Nick Cobbing's photographs pretty well (he's done a fair bit of work for Greenpeace in the past) but, on the advice of our picture editor, I went to have a nose around his website where he's organised some of his photos into stories.

Ken Livingstone wants it for London, Hilary Benn is giving money to it and Adam and Debbie are bringing it to Ambridge. After a couple of millennia in the sidelines, anaerobic digestion has finally hit the big time (well, The Archers, anyway) - which is why we've chosen it for this second edition of the Weekly Geek.

Every year, we bury thousands of tonnes of waste food in landfill sites around the UK. We produce almost one and a half million tonnes of sewage a year (don't do the maths - it's disturbing), which is mostly spread on land, incinerated or buried as landfill. And we produce enormous amounts of agricultural waste on our farms. All of this waste breaks down to release greenhouse gases as it decomposes.

The Olympic Energy Centre

The Olympic Delivery Authority has long said it wants the London Olympic games in 2012 "to be the first sustainable Games".

Well, today it's unveiled a design for its energy centre - complete with a combined cooling, heat and power (CCHP) plant fuelled by sustainable biomass (woodchip) and natural gas.

With just over a week to go until the consultation process ends, London mayor Ken Livingstone is keeping up the pressure on the government to abandon plans to build a third runway at Heathrow airport. During a visit to Sipson, one of three villages threatened by the bulldozers if the plans go ahead, Ken said: "It is vital that all airport expansion in London and the South East, including Heathrow, is halted now as it is completely contrary to the growing evidence on the role of aviation in contributing towards catastrophic climate change.

Excellent news reaches us from the Philippines where a ban on old-fashioned incandescent bulbs has recently been announced.

President Gloria Macapagal Arroyo announced plans for phasing out inefficient bulbs by January 2010, adding the Asian archipelago to the growing list of countries, including Ireland and Japan, which are slashing their emissions by shifting to compact fluorescent lamps (CFLs). So pressure is building up on our own government - and indeed the entire EU - to bring in their own mandatory efficiency standards for light bulbs.
