Responsible Research and Governance at the Science-Policy Nexus of Climate Change: New Discourses, Epistemic Communities and Climate Policy Regimes through Climate Engineering?

气候工程（CE）是一个新兴的研究和技术开发领域，在气候科学和气候政策的交叉点，通过增加大规模的气候干预的主要组合的缓解和适应政策，可能会打乱它们之间的既定界限。拟议的项目旨在更好地了解CE是否，如何以及在何种程度上发挥了作用，在科学和政治上应对气候变化的全球挑战。CE-SciPol 2将以SPP 1689第一阶段的研究为基础，扩大其实证重点和分析视角。CE-SciPol 2将（1）研究如何在科学，决策和公民社会的多个领域内和跨领域形成负责任的研究和CE治理的概念。运用定量和定性的话语分析方法，我们将进一步探讨与CE有关的行为者如何定义问题和解决方案，在气候变化研究和治理，以及他们如何定位自己的各种问题的利害关系，如知识质量，风险管理，可接受性，合法性和气候政策设计。除了从自然科学的文件的综合语料库，我们将系统地考虑从社会科学，法律和人文科学的文件，检查CE相关的争议，他们提供了不同的意见与跨领域的争论动态一起。在此基础上，我们将（2）确定不同的认知社区，他们如何评估CE相关的研究，技术开发和治理方法的可接受性，沿着气候政策的可信度和合法性，包括建立国际气候变化制度。该项目还将通过专家访谈和参与者观察，探讨在不同科学和工程学科以及不同机构领域的背景下，CE方法的有争议的表达和评价。我们还将（3）观察在COP 21之后，既定的气候变化制度在多大程度上受到压力，导致其削弱或加强。因此，我们将特别关注IPCC如何评估CE方法的风险，挑战和机遇，以及如何在专门用于管理CE研究，实验，技术部署和气候变化缓解的监管和政策框架中进行和实施这些评估。气候政策的持续发展将被考虑，以更好地了解CE是否会进一步获得承认为气候政策的“第三种选择”。

Climate engineering (CE) is an emerging field of research and technology development at the intersection of climate science and climate policy, potentially dislocating the established boundaries between them by adding large-scale climate intervention to the predominant portfolio of mitigation and adaptation policies. The proposed project aims at better understanding if, how, and to what extent CE has played a role in the ways that the global challenge of climate change has been addressed both scientifically and politically. CE-SciPol2 will build on the research conducted in the first phase of SPP 1689, expanding both its empirical focus and analytical perspectives. CE-SciPol2 will (1) examine how notions of responsible research and governance of CE have been shaped within and across multiple arenas of science, policy-making and civil society. Applying both quantitative and qualitative methods of discourse analysis, we will further investigate how actors concerned with CE define problems and approach solutions in climate change research and governance, and how they position themselves to the various issues at stake, such as knowledge quality, risk management, acceptability, legitimacy, and climate policy design. In addition to the comprehensive corpus of documents from the natural sciences, we will systematically consider documents from the social sciences, law, and humanities, examining the distinct views on CE-related controversies they provide together with the argumentative dynamics across arenas. On this basis, we will (2) identify distinct epistemic communities with respect to how they assess the acceptability of CE-related research, technology development, and governance approaches, along with the credibility and legitimacy of climate policy, including the established international climate change regime. The project will explore, also through expert interviews and participant observation, the contested articulations and valuations of CE approaches against the background of different disciplines of science and engineering and of different institutional domains. We will (3) also observe the extent to which the established climate change regime has come under pressure in the aftermath of COP21, leading either to its weakening or strengthening. Hereby, we will pay particular attention to how the IPCC has been assessing the risks, challenges, and opportunities of CE approaches, and how such assessments have been taken up and implemented in regulatory and policy frameworks dedicated to govern CE research, experimentation, technology deployment, as well as climate change mitigation. Ongoing developments in climate policy will be considered to better understand whether or not CE will further gain acknowledgement as a "third option" of climate policy.
