Want to participate in what is fast becoming latest thing in green personal responsibility, then start a CRAG. People all over the UK are getting together on a voluntary basis to form Carbon Rationing Action Groups CRAG’s. Each group negotiates a constitution allocating an annual carbon ration to be divided equally amongst its members, and rules about what happens when exceedences occur. At the end of the year they hold a ‘carbon audit’ and individuals make contributions to the group based on their emissions levels. Several dozen CRAGs have been formed over the past year, and recently the first overseas group has been set up in Maryland, USA. So whether it is out of a desire to start making a difference in the battle against climate change, or if you what to better understand how you might be affected if mandatory carbon emissions allowances were introduced – something the UK government is considering right now; Cragging might be just up your street!
