While we think it's lovely that Defra has launched a carbon calculator, we can't help but notice that a few other organisations have already developed similar tools (here, here, here, here, here, here, here, here and here, say).
I'm not knocking carbon calculators (they're useful tools and lots of us here in the office use them), and obviously personal action to help combat climate change is invaluable. But really, is this what David Miliband should be spending his time and our money on?
