ABSTRACT
This study conducted a comprehensive climate impact assessment of Apayao State College (ASC) to evaluate its carbon footprint and identify key emission sources across electricity consumption, diesel generators, transportation, and waste management. Using the GHG Protocol methodology, the research quantified annual CO₂ emissions at 196,405.63 kg, with electricity (43.6%), college vehicles (31.4%), and diesel generators (23.1%) as the dominant contributors. Waste generation accounted for 1.9% of emissions, though landfill-bound residual waste represented 77.5% of waste-related emissions due to high methane potential. The analysis revealed critical inefficiencies, including reliance on coal-powered grid electricity (85,687 kg CO₂e/year), inconsistent generator use (45,329 kg CO₂e/year), and under optimized vehicle fleets (61,623 kg CO₂e/year). Infrastructure audits highlighted energy waste from 499 non-functional lights and 71 air conditioning units in high-consumption buildings. The study underscores ASC’s role as a sustainability leader in the Cordillera region, demonstrating how institutional reforms, community engagement, and clean energy transitions can yield both environmental and financial benefits.
