Greenhouse Gas Inventory Standard for Cities: a Case of Jakarta

This paper presents the results of a study on developing the GHG Emissions Inventory for Cities in Indonesia, in which Jakarta has become a case study. The inventory has measured and disclosed a comprehensive GHG emissions inventory and to total these emissions using an approach that categorizes all emissions into scopes, depending on where they physically occur, i.e., Scope 1 for direct emissions and Scope 2 for indirect emissions. The GHG emission level of Scope 1 is estimated based on the IPCC 2006 (Tier-1/2), while Scope 2 employs national/local emissions factor that refers to the grid-connected emission factor of JAMALI. Based on the latest inventory in 2018, the GHG emissions profile of Jakarta is summarized as follows, i.e., the GHG emissions of Scope 1 is from direct fuels combustion in transport, industry, commercial and residential sectors (33.5%), fuels combustion in two power generations located in Jakarta (13.8%), and the remaining 3.8% is from waste treatment activity. The GHG emission of Scope 2 (48.8%) comes from the use of electricity (supplied by JAMALI-grid) generated outside the boundary of Jakarta. In addition, this study also shows estimates result of local pollutants that are affecting air quality.
