Delivering the next generation of open integrated assessment models for net zero sustainable development

最近的文献强调了气候减缓、适应和融资之间的相互作用，以及气候行动与其他发展议程之间的相互作用，包括可持续资源利用、人类发展和公平以及环境压力。这样一个相互关联的政策环境需要一个由学科、方法和工具组成的综合生态系统。尽管综合评估模型（iam）在过去十年中取得了重大进展，但鉴于《巴黎协定》和净零目标，在其设计、使用和是否足以应对未解决和新出现的问题方面仍存在一些批评。这些包括开放性、合法性和所有权，以及代表需求侧和更广泛的社会变革的技术可行性、跨部门互动、物理影响和适应、气候融资和劳动力动态以及其他可持续性目标。DIAMOND将更新、升级并全面开放6个在科学和政策过程中具有象征意义的iam，提高其部门和技术细节、时空分辨率和地理粒度。它将进一步增强建模能力，以评估符合《巴黎协定》的缓解途径的可行性和可取性、它们与适应、循环经济和其他可持续发展目标的相互作用、它们的分配和公平效应、它们对极端情况的抵御能力，以及强有力的风险管理和投资战略。这将通过整合来自心理学、金融研究、行为和劳动经济学、运筹学和物理科学的工具和见解来实现。我们将开发一种跨学科的科学方法，使实施过程合法化，共同创造扩展气候科学前沿的研究问题，并建立充满活力的实践社区，以透明地开放模型增强和发展能力，从而降低进入已建立的IAM社区的门槛

Recent literature has underlined the interplay among climate mitigation, adaptation, and finance, as well as between climate action and other development agendas, including sustainable resource use, human development and equity, and environmental pressures. Such an interconnected policy environment requires an integrated ecosystem of disciplines, methods, and tools. Despite the significant evolution of integrated assessment models (IAMs) in the last decade, there remain several criticisms on their design, use, and adequacy to respond to unaddressed and emerging questions in the light of the Paris Agreement and net-zero ambition. These include openness, legitimacy, and ownership, as well as technical feasibility to represent demand-side and broader societal transformations, cross-sectoral interactions, physical impacts and adaptation, climate finance and labour dynamics, and other sustainability goals. DIAMOND will update, upgrade, and fully open six IAMs that are emblematic in scientific and policy processes, improving their sectoral and technological detail, spatiotemporal resolution, and geographic granularity. It will further enhance modelling capacity to assess the feasibility and desirability of Paris-compliant mitigation pathways, their interplay with adaptation, circular economy, and other SDGs, their distributional and equity effects, and their resilience to extremes, as well as robust risk management and investment strategies. This will be done via integration of tools and insights from psychology, finance research, behavioural and labour economics, operational research, and physical science. We will develop a transdisciplinary scientific approach to legitimise the implementation process and co-create research questions that stretch the frontiers of climate science, as well as establish vibrant communities of practice to transparently open model enhancements and to develop capacities, thereby lowering the entrance barriers to the established IAM community
