Despite Indonesia's commitment to the 2015 Paris Agreement, its efforts to reduce greenhouse gas emissions by 2030 remain highly insufficient. In Bali alone, waste generation has surged by 30%, largely due to low public awareness of proper waste management. The impacts of climate change extend beyond environmental degradation, affecting social and economic dimensions as well. As of 2021, over 54% of Indonesia’s workforce is concentrated in sectors vulnerable to climate change mitigation and adaptation policies. However, the country’s demographic dividend presents a strategic opportunity to address these issues through education. Higher Education Institutions (HEIs), with approximately 8.5 million active students, are uniquely positioned to promote pro-environmental behavior (PEB) and shape environmentally responsible future professionals. While Green Human Resource Management (GHRM) has been linked to PEB in corporate settings across Asia, its implementation within HEIs remains underexplored. GHRM is vital in embedding sustainability values and cultivating green organizational culture (GOC), a key driver of PEB. Despite its importance, GOC remains underrepresented in higher education sustainability research.
