The study determined the contribution of the “Adopt-A-Tree Program” of the maritime university, John B. Lacson Foundation Maritime University (JBLFMU)-Molo towards the global warming mitigation. This study included the experiences, learnings, and challenges of the faculty members, staff, and students as part of the environmental education (EE) of the university. The researchers employed the mixed-method by Creswell (2016). The quantitativestatistical tools used in this study were frequency count, percentage, and rank. The “global warming mitigation contribution” was measured using the “shadedarea” contributed by the trees and the identification of the “flora” thriving under the identified trees. On the qualitative method, the “open-ended questionnaires” were utilized to gather the necessary statements, comments, and experiences of the different stakeholders of the project. The open-ended question approach allowed the subjects to answer based on their own frame of reference rather than structured pre-arranged questions, getting the subjects to freely express their thoughts around particular topics (Bogdan, R.C, & Biklen, S.K. (2003). The researchers categorized the qualitative views of the respondents to come up with different “themes” with regards to EE. Interview was conducted to validate some of the qualitative inputs of the respondents. The respondents of the study will be the selected department heads, faculty members, staff, and students of JBLFMUMolo. Results of this study lead to an enhance environmental education, awareness, and attitude of the different stakeholders and their perceptions and the significant role of this project towards global warming mitigation initiatives.
