The textile and apparel industry has been facing significant challenges in implementing green supply chain management practices. Experiencing inconsistent, slow, and fragmented adoption despite the increasing interest, external pressure and potential benefits. This study aims to address the knowledge-action gap in green supply chain management by exploring the potential adaptability of Implementation Science frameworks, traditionally used in healthcare, to the unique contexts of the textile and apparel sector. An exploratory, qualitative research methodology was employed utilizing semi-structured interviews, held with diverse textile and apparel industry professionals and experts. Findings indicate that structured frameworks as beneficial for enhancing clarity, efficiency, and standardization in green supply chain management efforts. The Knowledge-to-action framework (KTA) was found most relevant due to its emphasis on knowledge creation and translation, feedback loops, and adaptability. KTA's iterative process helps address common implementation barriers such as resistance to change, lack of clear guidelines, and difficulties in scaling pilot projects, aligning with the industry's need for systematic approaches to identify and overcome such barriers. Adaptions to the KTA framework for better alignment in textile and apparel context include: the addition of collaboration throughout, mobilizing internal company knowledge and early considerations of local supplier contexts. This research underscores the critical relevance of implementation science in guiding efficient green supply chain management transitions, offering practical implications for policymakers, companies, and researchers in fostering systematic and scalable adoption of green practices across the textile and apparel industry. It can help bridge a significant gap in green supply chain management literature by providing clear, practical tools for directing the actual implementation process.
