S DN Ragunan 08 Pagi and SDN Grogol Selatan 09 Pagi are two out of four schoolsin Jakarta officially designated by the Jakarta Provincial Government as net zerocarbon concept schools. These schools prioritize not only environmentally friendlybuildings and facilities, but also emphasize environmental education andcurriculum. The aim of this study is to analyze carbon dioxide (CO2) emissions,compare PM2.5 concentration in the two net zero carbon schools, explore therelationship between meteorological parameters (humidity and temperature) andparticulate matter 2.5 microns, and assess the green building criteria implementedby these two schools. The estimation of CO2 emission calculations is based on theelectricity consumption requirements of electronic devices and the electricityconsumption during the months of April, May, and June 2023. The CO2 emissionfactor from the electricity source, the Java-Madura-Bali interconnected system, is0.870 kg/CO2/kWh (Directorate General of Electricity, Ministry of Energy andMineral Resources, 2019). PM2.5 monitoring was conducted using the low-costEdimax Airbox sensor during April and May 2023. The research results indicatethat the CO2 emission calculation in SDN Ragunan 08 Pagi is higher compared toSDN Grogol Selatan 09 Pagi. This difference could be attributed to varyingactivities and energy usage in the two schools. The PM2.5 concentration is lower atSDN Grogol Selatan 09 Pagi compared to the Ambient Air Quality Standard(BMUA), Government Regulation No. 22 of 2021. The correlation betweenmeteorological parameters and PM2.5 is weak at all measurement points, suggestingthat other factors such as surrounding environmental conditions and the influenceof motor vehicle activities affect PM2.5 concentrations. Both SDN Grogol Selatan09 Pagi and SDN Ragunan 08 Pagi have implemented green building criteriaincluding Land Use Suitability, Energy Efficiency and Conservation, Air Quality,and Space Comfort, in accordance with the aspects or criteria established byGREENSHIP version 1.2
