National Soft Landing CO2 trajectories under global carbon budgets

One of the most important outcomes during the last Conferences of the Parties was the Durban Platform for Enhanced Action, which can be seen not only as a window of opportunity, but as a necessity to act. Our concern in the present paper is with the identification of an appropriate international climate-policy architecture in order to foster climate governance. The paper attempts to raise awareness towards the Soft landing commitment scheme which is proposed as an element of answer to the climate-policy dilemma. The scheme (REDEM for REDuction of Emissions) proposes a pathway to stabilize the emissions with a timing and a level of commitment, which are differentiated on the basis of capability (per capita income levels) and responsibility (per capita emissions). We present a couple of simulation examples which show different ways to conceive the shapes of the emissions and their rates of variation. The REDEM algorithm is designed as a tool for the benchmarking of supposed national emission reduction trajectories. The tool shows a practical way to guide the potential national trajectories, through a convergence mechanism into a comprehensible framework.
