The paper presents a reflection on the dialogue between the Islamic and Christian faiths on the subjects of the environment and sustainability, highlighting the existence of common views which can provide an important impetus for global reflection on the ecological crisis and sustainable development. The study aims to underscore the significance of the discourse among faith leaders on this matter, which has been disseminated to other religious communities and has led to the establishment of a shared commitment within UNEP Faith for Earth initiative at the United Nations Climate Change Conference, held in Dubai in 2023.
