Now this is great idea, and perfect example of the small things...big changes philosophy.
Don't think you'll ever get round to doing all that green, right on stuff which will make a difference to the world, even though it's actually pretty easy to do?
Then sign up to the Nag. And they will, well, nag you.
They'll set you a challenge, and keep nagging you each month (via email) to do it. The first of these is to switch to green electricity. Once you have done this…or you admit defeat - which I'm sure would result in some scathing response - you'll be set another challenge to get you teeth into.
Feel free to sign up here.
