E-Mail What drives the feasibility of climate scenarios commonly reviewed by organizations like the Intergovernmental Panel on Climate Change (IPCC)? And can they actually be achieved in practice? A new systematic framework can help understand what to improve in the next generation of scenarios and explore how to make ambitious emission reductions possible by strengthening enabling conditions. While the IPCC is in the midst of the drafting cycle of the Sixth Assessment Report, whose publication will start in the second half of 2021, there is an ongoing debate on how to assess the feasibility of ambitious climate mitigation scenarios developed through integrated assessment models and to what extent they are actually achievable in the real world. In their new study published in Environmental Research Letters, researchers from IIASA and the RFF-CMCC European Institute on Economics and the Environment (EIEE) developed a systematic framework that allows identifying the type, timing, and location of feasibility concerns raised by climate mitigation scenarios.
