For around 40 years, the Gulf Cooperation Council (GCC) countries have been developing cooperative frameworks that aim at enhancing security and economic cooperation as well as establishing joint action on common threats such as environmental degradation of the Gulf waters. Population and economic growth, alongside global issues such as climate change, have increased the pressure on vulnerable ecosystems. They have also resulted in the expansion of environmental concerns and the associated risks. In fact, contemporary sustainability issues represented by global visions such as the Sustainable Development Goals (SDGs) include numerous issues to tackle sustainability in a comprehensive manner. Using mapping of the SDG-based sustainability issues, this paper examines interstate relations among GCC states aimed at achieving comprehensive sustainability outcomes through regional environmental cooperation. It highlights the conceptual and practical relevance of such regional cooperation among GCC states, which share a common pool resource (the Gulf) and many socio-economic, physical, and cultural similarities. Sustainability issues, interstate relations and GCC-based cooperation are examined in terms of policies, legacies, interests and commitments across different sectors; e.g., water, energy, agriculture, ecosystems, and climate. Despite not being comprehensive and not resulting in strong, enforceable outcomes, regional environmental cooperation in the GCC region has been valuable for environmental collaboration and policy coordination. There is a need to strengthen cooperative frameworks, issue representation, and participation in order to overcome the recent rise in interstate competition and political rifts that are negatively affecting the capacity of the regional level to contribute to future environmental outcomes.

大约40年来，海湾合作委员会（GCC）国家一直在建立合作框架，旨在加强安全和经济合作，并针对海湾水域环境恶化等常见威胁采取联合行动。人口和经济增长以及气候变化等全球性问题加剧了脆弱生态系统的压力。它们还导致对环境的关注和相关风险的扩大。实际上，以全球视野为代表的当代可持续性问题，例如可持续发展目标（SDG），包括许多问题，需要以综合方式解决可持续性问题。使用基于SDG的可持续发展问题的地图，本文研究了海湾合作委员会国家之间的州际关系，旨在通过区域环境合作实现全面的可持续发展成果。它强调了海湾合作委员会国家之间这种区域合作在概念上和实践上的相关性，这些国家拥有共同的资源库（海湾地区）以及许多社会经济，自然和文化上的相似之处。从不同部门的政策，遗产，利益和承诺方面审查了可持续性问题，州际关系和基于海湾合作委员会的合作；例如，水，能源，农业，生态系统和气候。尽管还不够全面，也没有产生有力的，可强制执行的结果，但海湾合作委员会地区的区域环境合作对于环境合作和政策协调还是很有价值的。有必要加强合作框架，
