Today is national carbon footprint day. The idea is that once a year you take meter readings of various things: Electricity, Gas, water, Milometer on your car (easy one that for me!) and flights over last year (again easy for me) and then the following year you update it. It makes it easy to see what progress you are making. I’m going to do my readings tonight ready for next year – it’ll help me to assess how I’m doing with the 10:10 target!
