Ed Miliband

While today is unlikely to go down in the annals of history as Green Wednesday, it's still a significant day for those of us concerned about climate change as climate and energy secretary Ed Miliband unveils his big energy strategy.

The strategy - the Low Carbon Transition Plan, no less - comes in the form of not one but a whole ream of papers (including an energy white paper) covering renewable energy, transport, industry and carbon budgets. Together, they form a blueprint explaining how the government hopes to achieve the emissions reductions it's legally obliged to deliver, thanks to the EU renewable energy targets and the UK's own Climate Change Act.

Was it a red letter day for green energy? Let's see.

It's been a long time since there were polar bears at London Zoo, but the famous attraction still houses many other species which are threatened by the effects of climate change. So I can't help but wonder whether this fact registered with Gordon Brown (himself an endangered species) as he stood up at the zoo to present his blueprint for a global climate action plan.

We've made some progress on the coal campaign lately, with Climate and Energy Minister Ed Miliband finally ruling out any new coal-fired power stations that don't capture a proportion of the carbon they emit. But that's not nearly enough to save the climate.
