Abstract—To meet the United Nations Sustainable Development Goals and the 2050 Net Zero Emission Policy, the European Union introduced the EU Taxonomy and the Carbon Border Adjustment Mechanism (CBAM) in 2020, making green product environmental declarations crucial. Taiwan promotes Sustainable Finance Classification Standards through Green Building Materials Labels (GBMLs). This study utilizes Phenomenon-Based Learning (PBL) with a focus on green product labeling, delivering short-term seminars on sustainable environmental expertise. A one-day seminar was attended by 346 participants. Initially, a questionnaire assessed their understanding of green building material labeling. After the PBL session, a second questionnaire gauged cognitive and importance assessments from 98 participants. The Boston Consulting Group (BCG) matrix analyzed the impact of PBL on awareness and the importance of a sustainable economy through green product labeling. A two-factor categorical analysis using the Pearson chi-square test was also conducted. Results showed 80% were first-time attendees aware of green product labeling, and 51% had backgrounds in architecture, interior design, and materials. The BCG matrix analysis in the second stage revealed that the significance of green product labeling to Taxonomy Regulation activities was high, with 95.9% in the first quadrant (+,+) and only 3% in the third quadrant (-,-). The Pearson chi-square test indicated no significant association between professionals in interior design and the importance of green product labeling (p > 0.05), suggesting that awareness and importance of a sustainable economy were not influenced by professional occupation. However, individuals with professional backgrounds showed significant associations with the application of green product labeling in building regulations (p < 0.05), highlighting the influence of professional background.

Keywords—green building materials labels, phenomenon-based learning, taxonomy regulation, awareness, Boston Consulting Group (BCG) matrix, Pearson’s chi-squared test
