An operational framework for equity in the 2015 agreement

Abstract

Equity is a highly contentious but essential area of negotiation, if a stable and effective international climate agreement with broad participation is to be achieved. Three perspectives on the magnitude dimensions of equity are identified that need consideration in the process of formulating an agreement: agreement on a ‘safe’ temperature goal; agreement on the required global effort; and agreement on a fair division of contributions. The opportunities are explored for reconciling these perspectives in an operational framework for equity. Specifically, this means the importance of the adopted a global temperature goal of below 28C temperature increase by the end of the century. In addition, an initial approach to quantifying adaption costs is suggested, while the importance of arriving at a global mitigation goal is emphasized. It is argued that finance and technology support commensurate with the required global mitigation and adaptation effort is an important element of equity.
