Nan Pao is committed to achieving carbon neutrality by 2050 and has identified greenhouse gas (GHG) emissions management as a key priority in its Sustainability Report. To support this goal, PT Nan Pao Indonesia engaged Sustainahaus to conduct a GHG inventory in accordance with ISO 14064-1. The assessment covered direct emissions from company vehicles, generators, boilers, chemical use, and refrigerant leakage (Scope 1); indirect emissions from purchased electricity (Scope 2); and selected indirect emissions such as logistics, employee commuting, business travel, and hazardous waste transportation (Scope 3). Sustainahaus supported the process by defining organizational and reporting boundaries, conducting site surveys and data collection, performing GHG calculations, and preparing a GHG report in line with ISO 14064-1:2018, as well as assisting the client during third-party verification under ISO 14064-3.
