The spatial scope of the greenhouse gas (GHG) inventory calculation for the domestic settlement sector covers 19 land categories, including parks. The GHG inventory includes all emissions and absorptions of greenhouse gases resulting from land use and land-use changes and is calculated based on the approaches outlined in the IPCC 2006 guidelines. The GHG inventory for the settlement sector was only calculated for maintained settlements. The calculation focused on the CO2 absorption from biomass, which is one of the carbon reservoirs. The statistical calculation method used was Tier 2a, Approach 1. The inventory calculation period covers 1990-2022, with extrapolation applied for 1990-2001 and interpolation for 2003-2008 and 2020-2021. The canopy area of maintained settlements increased from 56,267 ha in 1990 to 116,779 ha in 2019, but has been analyzed to decrease since 2020. The carbon absorption in the settlement sector was –598,307 tc/ha/yr in 1990, increasing to –1,241,755 tc/ha/yr in 2019. However, in 2022, the absorption decreased to –1,198,995 tc/ha/yr, showing a decline since 2019. Therefore, in the case of maintained settlements, efforts to expand carbon absorption spaces within urban areas and minimize carbon loss are necessary to enhance GHG absorption.
