Abstract:
This research presents an assessment of an organization's carbon footprint of the Central Library, King Mongkut's University of Technology North Bangkok. In order to calculate greenhouse gas emissions as annual carbon dioxide equivalents (tonCO2eq), based on the guidelines for assessing greenhouse gas emissions of the Thailand Greenhouse Gas Management Organization (Public Organization). Data of this study collected in year 2021 and the year 2022.
The study, it was found that in 2 0 2 2, the Central Library released a total of 363.72 tons of CO2eq. Classified according to the extent of greenhouse gas emissions from highest to lowest in order as follows is the maximum range is Scope 1. Direct emissions from fuels (Diesel and Benzine), Methane emissions from the separation tank system and non aerated sewage treatment tanks and the amount from refrigerant leaks in water dispensers, refrigerators, and freezers equal to 230. 53 tons of CO2eq accounting for 63.38%.Next is Scope 2, indirect greenhouse gas emissions from the use of electrical energy equal to 123.27 tons of CO2eq accounting for 38.89% and the least is Scope 3, indirect greenhouse gas emissions from using A4 and A3 paper (white), using tap water. and waste (Landfill Side) equal to 9.92 tons of CO2eq accounting for 2.73%, respectively. The comparison of greenhouse gases emissions in year 2022 and 2021 (Year 2021 the greenhouse gas emissions are equal to 141. 66 tons of CO2eq) . It was found that the Central Library greenhouse gas emissions increased by 157%. Because in 2021, due to the epidemic of coronavirus (COVID- 19). The university offers online classes and all staff members are working from home. The Central Library has closed according to the university's announcement, which is different from the year 2022 when the university is open for normal teaching. The information obtained from this study can be used as a guideline in finding ways to reduce greenhouse gas emissions for the Central Library and the university.
