Cap and Share was originally developed by Feasta (the Foundation for the Economics of Sustainability) and is a regulatory and economic framework for controlling the use of fossil fuels in relation to climate stabilisation. Accepting that climate change is a global problem and that there is a need to cap and reduce greenhouse gas emissions globally, the philosophy of Cap and Share maintains that the earth’s atmosphere is a fundamental common resource. Consequently, it is argued, each individual should get an equal share of the benefits from the limited amount of fossil fuels that will have to be burned and their emissions released into the atmosphere in the period until the atmospheric concentration of greenhouse gases has been stabilised at a safe level.
