在人类世，重新审视地球上人类生命的生物物理极限的想法重新获得了势头。行星边界框架已成为一个强有力的屏障概念，尽管其为制定绝对可持续性评估和现实政策提供信息的能力仍不明朗。在这篇文章中，我们介绍了目前发展的绝对环境可持续性(AES)指标和评估的PBS信息的综合。我们首先探讨了在不同尺度上，PBS是如何被考虑在俄歇电子能谱研究中的。然后，我们对如何在标准化和协调全球和本地分配的安全操作空间份额方面达成共识提出了批评。我们认为，公共广播必须与作为主要社会经济驱动力的人类消费联系在一起，只有通过涵盖全球远程联系的整体观点才能解决全球关切问题。基于我们的研究结果，我们提出了未来由PBS提供信息的AES指标和评估的设计建议。
The idea of revisiting the biophysical limits of human life on planet Earth has gained renewed momentum in the Anthropocene. The planetary boundaries (PBs) framework has emerged as a strong guardrail concept, even though its capacity to inform the development of absolute sustainability assessments and realistic policies remains unclear. In this paper, we present a current synthesis of the development of absolute environmental sustainability (AES) indicators and assessments informed by PBs. We firstly explore how PBs have been considered in AES research at different scales. We then present a critique of how consensus could be reached in standardising and harmonising the share of globally and locally allocated safe operating spaces. We argue that PBs must be linked to human consumption as the main socio-economic driver and that planetary concerns can only be addressed through a holistic perspective that encompasses global tele-connections. Based on our findings, we provide recommendations for the future design of AES indicators and assessments informed by PBs.
