Netzero2040: Reaching climate neutrality in Austria by 2040: engaging stakeholders for model-supported scenario development. Data repository

This repository contains scenario results in pyam format, qualitative scenario narratives and drivers identified by stakeholders for the NetZero2040 project. NetZero2040 developed the first independent scenarios achieving climate-neutrality in Austria by 2040. We improve on previous analyses by employing a structured co-creation process involving stakeholders and modellers, simultaneously modelling the whole energy system and the electricity system in great detail, creating shared visions of a climate-neutral future. Results are openly available and have been broadly disseminated in the scientific community and to the public. Our scenarios are differentiated by assumptions on energy demand and imports of energy carriers. They show that a rapid electrification of transport and heating, in combination with a build out rate of renewable energies which is well above historical maxima in the Austrian power system, allow significant emission reductions until 2030, and that these measures are consistently required in all scenarios. However, after 2030 scenarios diverge and uncertainty about the most cost-efficient transformation measures prevail.本仓库收纳了NetZero2040项目的相关成果：采用pyam格式存储的情景模拟结果、定性情景叙事文本，以及经利益相关方识别的转型驱动因素。 NetZero2040项目首次构建了可实现奥地利2040年气候中和的独立情景方案。本研究相较于既往分析的改进之处在于：采用了利益相关方与建模人员共同参与的结构化协同共创流程，同时对全能源系统与电力系统开展精细化建模，以此构建气候中和未来的共同愿景。所有研究结果均已公开，并在科学界与公众层面得到广泛传播。本项目的情景方案基于能源需求与能源载体进口的不同假设进行差异化设定。研究结果表明：快速推进交通与供暖领域的电气化，结合远超奥地利电力系统历史峰值的可再生能源装机扩容速率，可在2030年前实现显著的温室气体减排，且该类措施在所有情景中均为必需项。但2030年后，各情景出现分化，关于最具成本效益的转型措施的不确定性始终存在。
