Abstract: Green Lean Six Sigma (GLSS) is an effective technique that combines Lean Six Sigma principles with an ecologically conscientious perspective. This paper thoroughly investigates the implementation of GLSS methodology in various industries. It tries to overcome performance issues and impediments while emphasising environmental awareness. The study adds to the body of knowledge and supports sustainability and operational efficiency by identifying and analysing barriers to adopting green technologies. The methodology employs tools such as multiple-criterion decision-making (MCDM), best-worst method (BWM), and principal component analysis (PCA) to prioritise difficulties and target improvement areas. Results highlight the importance of process efficiency and incorporating sustainable practices for long-term viability and a beneficial environmental impact. Overall, this research presents a proven methodology for standardising and applying sustainable manufacturing practices, increasing GLSS and sustainability knowledge.
