A prominent recent perspective article in this journal and accompanying open letter propose a broad international “non‐use agreement” (NUA) on activities related to solar geoengineering (SG). The NUA calls on governments to renounce large‐scale use of SG, and also to refuse to fund SG research, ban outdoor experiments, decline to grant IP rights, and reject discussions of SG in international organizations. We argue that such pre‐emptive rejection of public research and consultation would deprive future policy‐makers of knowledge and capability that would support informed decisions to safely and equitably limit climate risk, sustain human welfare, and protect threatened ecosystems. In contrast to the broad prohibitions of the NUA, we propose an alternative near‐term pathway with five elements: assess SG risks and benefits in the context of related climate risks and responses; distinguish the risks and governance needs of SG research and deployment; pursue research that treats uncertainties and divergent results even‐handedly; harness normalization of SG as a path to effective assessment and governance; and build a more globally inclusive conversation on SG and its governance. These principles would support a more informed, responsible, and inclusive approach to limiting climate risks, including judgments on the potential role or rejection of SG, than the prohibitory approach of the NUA.This article is categorized under: Climate and Development > Social Justice and the Politics of Development Policy and Governance > Multilevel and Transnational Climate Change Governance Policy and Governance > National Climate Change Policy

就太阳能地球工程进行以证据为基础、负责任和包容性的辩论：对拟议的不使用协议的回应


该期刊最近发表的一篇著名观点文章和随附的公开信提出了一项关于太阳能地球工程（SG）相关活动的广泛国际“不使用协议”（NUA）。 NUA呼吁各国政府放弃大规模使用SG，并拒绝资助SG研究，禁止户外实验，拒绝授予知识产权，并拒绝在国际组织中讨论SG。我们认为，这种对公共研究和咨询的先发制人的拒绝将剥夺未来政策制定者的知识和能力，而这些知识和能力将无法支持明智的决策，从而安全、公平地限制气候风险、维持人类福祉和保护受威胁的生态系统。与 NUA 的广泛禁令相反，我们提出了另一种近期途径，包含五个要素：在相关气候风险和应对措施的背景下评估 SG 风险和效益；区分SG研究和部署的风险和治理需求；开展公平对待不确定性和不同结果的研究；利用SG正常化作为有效评估和治理的途径；并就SG及其治理建立更具全球包容性的对话。这些原则将支持采取更加知情、负责任和包容的方法来限制气候风险，包括对 SG 的潜在作用或拒绝的判断，而不是 NUA 的禁止性方法。本文分类如下：气候与发展 > 社会正义和发展政策与治理的政治 > 多层次和跨国气候变化治理政策与治理 > 国家气候变化政策
