Going green is going to be a challenge. In fact, I have no idea where to start. Just now I tweeted this question to several environmental organisations: does anyone know of a scale to measure an individual’s ‘greenness’? I’m looking for some sort of green fitness test to show where I’m failing and how I can improve. I’ll also send some emails to environmental specialists and see what they suggest. I’m hoping to take stock of my current lifestyle, and to repeat the process at the end of 2012 – to see how much I’ve progressed. Does anyone have any suggestions?
