Purpose: The UN proclamation of 2005-2014 as the decade of education for sustainable development has been instrumental in creating awareness and driving higher education institutions (HEIs) in integrating sustainability into their system. The purpose of this paper is to explore and encapsulate practices adopted by universities and colleges across the globe in integrating sustainability in education (here refers to curriculum and pedagogy), research, campus operations and outreach programs. Design/methodology/approach: The review analyzed 229 peer-reviewed research studies in the time period 2005-2018 selected from 44 journals. The literature review was done in phases. The first phase was the selection of the database, the second phase was refining the database by eliminating irrelevant studies and the last phase was distributing selected studies on the basis of the journal, year and country of publication, research paradigm, sustainability integration in higher education, teaching techniques adopted by HEIs and research focus in publications. Findings: This study contributes to the literature review of sustainability in higher education. From the literature review, it is evident that sustainability has made inroads into HEIs, but only a few universities have been successful in implementing it holistically, integrating all the triple bottom line dimensions in balance. Practical implications: The study has practical implications for HEIs planning to integrate sustainability into teaching and learning and other aspects of educational practices. The findings and the examples of successful implementation of sustainable education by institutions around the world would help universities and colleges in formulating policies, strategies and practices that would promote sustainability on campuses. Originality/value: The literature reviews on sustainability in higher education so far have focused either on curricula, pedagogical approaches, assessment and reporting or barriers and solutions. This study attempts to offer a comprehensive view of the initiatives adopted by the institutions in incorporating sustainability in education, research, campus operations and outreach programs.
