A CRAG (or Carbon Rationing Action Group) is a group of people who have decided to act together to reduce their individual and collective carbon footprints. They do this in annual cycle. First they set themselves an annual emissions target or “carbon ration”. Then they keep track of their emissions over the year by keeping a record of their household energy use and private car and plane travel.
Finally, at the end of the year, they take responsibility for any “carbon debt” (i.e. emissions over and above their ration) that they have built up. All carbon debts are paid into the group’s “carbon fund” at an agreed rate per kilo of CO2 debt. The fund is then distributed as agreed by the members of the group.
