Zero-Waste Program Success: A Systems Approach to Indicators at the Micro, Meso, and Macro Levels

Existing sustainability tracking frameworks primarily address water, energy, and material durability, with limited focus on factors driving zero-waste (ZW) initiatives. The current sustainability tracking tools especially lack comprehensive assessment mechanisms to evaluate organizational progress toward ZW, especially in higher education institutions (HEIs). This study reviews the global literature (2000–2023) on ZW indicators in organizations, focusing on HEIs, using databases such as Scopus and Web of Science, with an emphasis on waste reduction and sustainability practices. Institutional theory is used to explain the adoption of ZW programs in HEIs through normative, mimetic, and coercive isomorphisms. This study finds that ZW initiatives in HEIs are driven by shared professional norms (normative isomorphism), imitation of best practices (mimetic isomorphism), and compliance with regulatory policies (coercive isomorphism). Education, full-time staff, sustainability offices, and student advocacy play key roles, while collaboration within sustainability networks further enhances these efforts. This study emphasizes the complex interplay of these isomorphic forces across different levels of influence.
