Abstract

The concept of safe and just Earth System Boundaries (ESBs) is a scientific framework that integrates environmental sustainability and social justice into an integrated structure to both maintain the ecological stability of the planet and prevent harm to the welfare of humans and other species. This framework was introduced by Rockström and colleagues in 2023. The approach is based on the idea that human activities should not exceed limits that both threaten the health of the Earth system and exacerbate social inequalities. This research aims to examine the key components and concepts of safe and equitable Earth system boundaries and the current status of this framework, including an analysis of the impacts of human activities on safe boundaries and considerations of equity. The research shows that currently, key components such as climate change, biosphere integrity, water and nutrient cycles, and aerosol pollution have exceeded acceptable limits set by global standards. The Safe and Just Earth System Boundaries Framework provides a quantitative basis for protecting the global commons, contributes to the Sustainable Development Goals, and has implications for policy and governance. Ultimately, the Safe and Just Earth System Framework provides a comprehensive approach to achieving sustainable development by balancing environmental constraints with social needs. The framework emphasizes the importance of integrating justice into environmental governance to ensure a fair and equitable distribution of resources and opportunities while maintaining Earth system stability.
