ABSTRACT
Indonesia targets the net zero emission (NZE) achievement in 2045 through the forest and other land
uses (FOLU) approach. In the NZE target evaluation, it is necessary to compare the carbon emissions
and sequestration at the regional level. This study aims to evaluate the NZE achievement in Central
Java for further clustering according to the results. Carbon sequestration data is obtained from the
land use of Rupa Bumi Indonesia (RBI), while carbon emission data is obtained through an individual
carbon footprint approach. In 2022, Central Java achieved the NZE, with a difference between carbon
sequestration and emissions of 9,025,367.00 tons of CO2 eq. However, there are almost half, or 15
districts/cities (42.86%), that have not achieved NZE, namely Semarang City, Klaten, Demak, Sukoharjo,
Kudus, Tegal, Surakarta, Sragen, Pekalongan City, Karanganyar, Tegal City, Salatiga, Magelang,
Magelang City, and Pati. It consists of at least 3 categories of regions, namely, 1) Districts/cities that
have reached NZE; 2) Districts/cities that have not reached NZE but are still able to be supported by
surrounding districts/cities; 3) Districts/cities that have not reached NZE and cannot be supported by
surroundings. There are efforts that are still needed to achieve NZE. Achieving NZE can be done by planting vegetation and reducing carbon emissions, especially from the energy, transport sectors, and
waste, considering the availability of the area and its sequestration capability in surrounding districts/
cities.
