Greenhouse gas emission: A case in the University of Science and Technology of Southern Philippines-Oroquieta
Abstract
The COVID-19 pandemic has temporarily decreased the greenhouse gas emissions of the University of Science and Technology of Southern Philippines-Oroquieta. However, as the pandemic became manageable, face-to-face classes were reimplemented in 2022, therefore utilizing laboratories and facilities to comply with the respective course requirements of the students, which caused an increase in emissions. Using the 2006 IPCC Guidelines for National Greenhouse Gas Inventories, this study estimates the total entity-level greenhouse gas emission of the campus for the base year 2022 under business-as-usual economic activity. This study investigates the comparison between emissions of mobile and stationary sources and the Scope 1 and Scope 2 emissions. The results revealed that the majority (96.18%) of Scope 1 emission was contributed by stationary combustion sources followed by mobile combustion sources with 0.3494 tCO2e and 0.01388 tCO2e, respectively, indicating a statistically significant difference. The Scope 2 emission contributes to the majority (99.07%) of the greenhouse gas emission with 38.5277 tCO2, while the Scope 1 emission only contributes 0.93% with 0.3633 tCO2e, further indicating a statistically significant difference. Based on the results, the greenhouse gas emission of the campus was 38.8910 tCO2e with an emission per capita of 0.0311 tCO2e, which was below the national average. Generally, there is a need for the campus to intensify commitments to climate actions, particularly in energy conservation, as this scope contributes to the majority of greenhouse gas emissions.
