Abstract
Purpose: This integrative review consolidated and synthesized diverse research articles aimed at investigating various environmental factors in sustainability education, including in the healthcare field. Likewise, it provided a holistic understanding of challenges, facilitators, and their significance. Method: Eight databases with different search terms were searched in this integrative review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).
