Keeping the Earth system in a stable and resilient state, to safeguard Earth's life support systems while ensuring that Earth's benefits, risks, and related responsibilities are equitably shared, constitutes the grand challenge for human development in the Anthropocene. Here, we describe a framework that the recently formed Earth Commission will use to define and quantify target ranges for a “safe and just corridor” that meets these goals. Although “safe” and “just” Earth system targets are interrelated, we see safe as primarily referring to a stable Earth system and just targets as being associated with meeting human needs and reducing exposure to risks. To align safe and just dimensions, we propose to address the equity dimensions of each safe target for Earth system regulating systems and processes. The more stringent of the safe or just target ranges then defines the corridor. Identifying levers of social transformation aimed at meeting the safe and just targets and challenges associated with translating the corridor to actors at multiple scales present scope for future work.

确定人与地球安全，公正的走廊

保持地球系统处于稳定和有弹性的状态，以保护地球的生命支持系统，同时确保公平分享地球的利益，风险和相关责任，这是人类世人类发展的巨大挑战。在这里，我们描述了一个框架，新成立的地球委员会将使用该框架来定义和量化满足这些目标的“安全，公正走廊”的目标范围。尽管“安全”和“公正”的地球系统目标相互关联，但我们认为安全主要是指稳定的地球系统，而目标仅是与满足人类需求和减少风险暴露相关。为了使安全和合理的尺寸保持一致，我们建议解决地球系统调节系统和过程的每个安全目标的公平尺寸。然后，较严格的安全范围或仅目标范围定义了走廊。确定旨在实现安全，公正的目标和挑战的社会变革杠杆，这些挑战与将走廊转变为多种规模的行为者有关，为今后的工作提供了空间。
