Energy

In the past, I've been a bit sniffy about carbon calculators and have tended to dismiss them, although if I'm honest it's been on principle rather than first-hand experience. From what I've seen, they oversimplify an incredibly complex issue and, as a colleague pointed out, shift the weight of responsibility onto individuals when it should be an energy-efficient government that leads the way.

But then I came across mobGAS, a calculator produced by the European Commission's Joint Research Centre which sits on your mobile phone and allows you to enter daily updates about your energy consumption. Hurray, a new application for me to fiddle with in a borderline obsessive-compulsive manner, and an excuse for a broader look at carbon calculators in general.

As Mayor of London, Ken Livingstone might not be the perfect politician but at least he's streets ahead of central government on climate change and reducing emissions in the capital. His latest ploy is to hold a light bulb amnesty during which Londoners can exchange their old incandescent bulbs for a bright new energy-efficient one.

According to london.gov.uk, you can take up to two old-fashioned bulbs to any London branch of B&Q between Friday 11 and Sunday 13 January and exchange them for compact fluorescent lamps (CFLs) provided by British Gas. Nice.

It will be the UK's first new coal fired power plant in 34 years. It will emit as much carbon dioxide as the 30 least polluting nations in the world combined. And the world's leading climate scientist has called it "a tipping point for the world".

The proposal for a new coal-fired power plant at Kingsnorth in Kent has been given the go-ahead by Medway Council. At a meeting last night, only three of the 16 councillers objected to E.ON's application, meaning that the plant - which will generate electricity in the most climate-wrecking way known to humankind - has been approved, potentially starting a new coal rush in the UK.

We're used to having some unusual people descending on our offices, but today's visit by David Cameron and several other members of the shadow cabinet is the most leftfield (or should that be rightfield?) visitation for some time. But they were here to launch a new policy that uses many of our own demands for renewable energy, a vital component in the struggle to limit the impacts of climate change.
