Universities have significant carbon emissions impact and face pressure to cut their operational carbon emissions around the world. This leads to growing interest of the academic and practice community in effective pathways for carbon reduction within higher education. In this context, the aim of the research is to investigate the strategies for decarbonising university operations and challenges being faced. Drawing from a mixed-method approach, a review of case studies, and a survey involving Higher Education Institutions (HEIs) in nearly 40 countries, it explores the interconnectedness of awareness, cultural and political dimensions, internal institutional structures, and technical approaches in achieving decarbonisation goals. The findings underscore awareness initiatives that enhance understanding of decarbonisation among educators and students in universities, and communities. The case studies as a review of experiences from diverse geographical regions illustrate varying strategies for carbon emissions reduction in HEIs, underscoring the adaptability of decarbonisation efforts across contexts. Additionally, cultural and political factors emerge as key determinants, requiring tailored strategies to navigate diverse contexts and garner public support. Finally, institutional structures, including financial constraints and regulatory barriers, and ageing infraestructure are identified as key barriers to effective decarbonisation efforts. The novelty of the paper resides on the fact that it highlights the need for integrating decarbonisation goals into institutional governance and planning mechanisms is essential for achieving long-term goal of net zero carbon and aligning with the global UN Sustainable Development Goals (SDGs). The study advocates for a holistic approach that considers social, economic, environmental and institutional dimensions in advancing decarbonisation within HEIs, rather than treating emissions as a purely technical issue. The effectiveness of decarbonisation measures is dependent on breaking down chronic structural and financial factors in the implementation, and is substantially supported by institutional practices that promote the engagement of all stakeholders and an open, transparent measurement of its impact. By addressing barriers, HEIs can pave the way for a sustainable and low carbon future while serving as catalysts for broader societal change.
