The international community has adopted the 17 Sustainable Development Goals (SDGs) as part of the 2030 Agenda for Sustainable Development in response to the growing concerns about climate change. SDG 13 on climate action and SDG 4 on quality education are highlighted as key goals, with SDG 13 effectively addressing climate change and its impacts, and SDG 4 ensuring inclusive and equitable quality education and promoting lifelong learning opportunities for all. Hence, the objective of this study is to analyse the promotion and dissemination of courses in the field of green taxation (also referred to in the international literature as environmental taxation, environmental law, environmental policy) and environmental law. This will entail identifying the existing courses in this area and the presence of Higher Education Institutions (HEIs) on social media (also referred to in the international literature as social networks). In this scope, considering the fundamental role of HEIs in the training of future professionals, this study will enhance the comprehension of green taxation in the educational context. The increasing use of digital platforms makes it necessary to analyse the digital presence of HEI on social media in other to promote the teaching of subjects such as green taxation, environmental law and sustainability. The researchers analysed information from the websites of the top 30 universities in the Shanghai Ranking and analysed existing courses in the field of green taxation and environmental law. Also identified are the top five social media most commonly used for promoting and communicating between students and intuitions.
