This paper shows how the leading Higher Education Institutions (HEIs) in the UI GreenMetric World University Ranking communicate their environmental sustainability policies through their websites. Specifically, this paper analyses the presence of sustainability-related sustainable development goals on the websites of the top 100 universities in the UI GreenMetric World University Ranking (2021). In the area of university social responsibility, sustainability is less commonly communicated, hence the need to delve deeper into the presence of these messages, carrying out a descriptive study using content analysis as a form of data extraction. The conclusion is that neither position in the ranking nor geographic area are decisive for developing better communication about sustainability. In terms of content, sustainability features on the websites are in three key dimensions of the communication of HEIs worldwide (Climate change, Efficiency of sustainable cities and communities and Striving for peace and justice). Thus, the areas for improvement are around the positioning of this sustainability-related content on their home pages, improving location and format (especially video). Moreover, reinforcing reputational messages, through plans or programmes, as well as improving engagement working on the multi-directionality to other social media, is required.

大学的社会责任和可持续性。他们如何在 SDGS 上开展工作以及如何在网站上传达这些信息

本文展示了 UI GreenMetric 世界大学排名中领先的高等教育机构 (HEI) 如何通过其网站传达其环境可持续性政策。具体来说，本文分析了 UI GreenMetric 世界大学排名（2021 年）中排名前 100 的大学网站上与可持续发展相关的可持续发展目标的存在情况。在大学社会责任领域，可持续性的传达较少，因此需要更深入地研究这些信息的存在，使用内容分析作为数据提取的一种形式进行描述性研究。结论是，排名位置和地理区域对于更好地开展可持续发展沟通都不是决定性的。从内容上来说，气候变化、可持续城市和社区的效率以及争取和平与正义）。因此，需要改进的领域是围绕其主页上与可持续发展相关的内容的定位，改进位置和格式（尤其是视频）。此外，还需要通过计划或计划来强化声誉信息，以及提高其他社交媒体的多向性参与度。
