TY - RPRT U1 - Forschungsbericht A1 - Vieweg, Marion A1 - Sterk, Wolfgang A1 - Hare, Bill A1 - Hagemann, Markus A1 - Fekete, Hanna T1 - Squaring the circle of mitigation adequacy and equity : options and perspectives T2 - Climate change N2 - The report surveys current proposals and positions on issues such as differentiated participation of countries in the new agreement, a differentiated spectrum of commitments, effort sharing and options for how to organise the negotiation process. The report finds that for the level of participation, the selection of commitment types, and choice of effort-sharing approaches there is no silver bullet. A portfolio approach that incorporates multiple options may be most suited to ensure environmental effectiveness, cost- effectiveness and political feasibility.
