How hard can it be?

Right, after scarcely any thought at all, I have decided to try and reduce my carbon footprint. I could go all-out and move to a yurt, compost my own bodily waste and raise organically reared yaks, but it all seems a bit of a faff and, anyway, the lawn is far too small for the yaks. Accordingly I have come up with a sort of dumbed-down and, yes I know, largely token-effort version of this:

I am going to... ... do one thing. A month. And see how it goes. That's one lifestyle change a month - nothing too arduous, nothing too radical. Then I'll sort of randomly blog about it - my successes, my failures and whether or not I think it's made a blind bit of difference. I'll also keep you up to speed on what the rest of the family make of it. Oh, and I'm hoping some more people might join me. I'll post my good intention for the month and you can pledge to try the same if you like. You could also suggest good intentions for subsequent months and, if I think I can attempt them with a cup of tea in one hand, I might take you up on them.
