The atmosphere has a limited capacity to soak up green house gases. Carbon rationers believe that this represents a unique shared resource.
In a carbon rationing society, those producing more than their fair share (or ration) of green house gases can only do so by finding someone who is living within their fair share and therefore has some ration to spare. In this way, polluters are penalised, the rest of society benefits and the total amount of green house gases produced is controlled.
If we reduce the size of our ration year by year, carbon rationing becomes a pathway to a fairer, lower carbon future.
