Climate targets have become prominent in the media and public debate recently, largely as a result of pressure exerted by groups such as Extinction Rebellion, who have advocated a target of net zero emissions of greenhouse gases by as early as 2025. The current article aims to draw some of the heat out of that debate and to shed some light on the issues raised by climate targets, including their level of ambition. It does so by developing a taxonomy of climate targets – setting out the choices confronting those designing national responses – and then examining those choices through a normative, values framework. Given the threat posed by climate change to humans and the ecosystems of which they are a part, it is important that climate targets are optimally constructed. The taxonomic and values framework laid out in the current article is designed to help with this.

击中目标？分析目标在气候法中的使用

气候目标最近在媒体和公众辩论中变得突出，主要是由于灭绝叛乱等团体施加的压力，他们主张最早在 2025 年实现温室气体净零排放的目标。 本文旨在从这场辩论中汲取一些热度，并​​阐明气候目标提出的问题，包括其雄心程度。它通过制定气候目标分类法来实现这一点——列出那些设计国家响应的人面临的选择——然后通过规范的价值观框架检查这些选择。鉴于气候变化对人类及其所在的生态系统构成的威胁，优化构建气候目标非常重要。
