Semarang-Demak coastal area is the current location for giant sea wall construction, which also functions as a toll road across two regions. The construction process reduces mangrove land areas that may have ecological destruction. As we know, mangrove areas play an important role in the Semarang-Demak regions as the carbon sink for global warming mitigation. Hence, this study aims to (1) analyze the current capacity of the carbon stock, (2) mangrove vegetation profiling, and (3) develop a sustainable mangrove ecosystem management model in the coastal area of Semarang-Demak. The research was conducted using descriptive exploratory with a non-destructive test using an allometric equation determined based on mangrove tree stands. The results showed that the total above-ground biomass (AGBs) or the potential above-surface biomass content at the study site ranges from 34.72 ± 6.51 Mg/ha up to 101.06 ± 13.71 Mg/ha. Potential carbon stocks (C-stock) at the research site (lowest C-stock) were 16.32 ± 3.06 MgC/ha or ranging from the lowest 59.83 ± 11.21 MgC/ha to the highest 174.17 ± 23.63 MgC/ha for CO2−e (carbon dioxide equivalent emissions). For this reason, an integrated effort is needed between components for the sustainability of the mangrove ecosystem in the coastal area of Semarang-Demak. Graphical Abstract: The coastal area of Semarang-Demak is currently the location for the construction of the sea embankment toll road project. This development has an impact on reducing mangrove land which has been one of the important ecosystems in the Semarang-Demak area, one of which is a carbon sink for mitigating global warming. The research design in this study is descriptive exploratory with research methods non-destructive test with allometric equation determined based on mangrove stands. It is found that the total Above-ground Biomass (AGBs) or the potential above-surface biomass content at the study site ranges from 34.72 ± 6.51 up to 101.06 ± 13.71 Mg/ha. With a range of potential carbon stocks (C-stock) at the research site, it is known that the lowest C-stock is 16.32 ± 3.06 MgC/ha. The total C-stock, when converted to CO2–e or carbon dioxide equivalent emissions, ranged from the lowest 59.83 ± 11.21 MgC/ha and the highest 174.17 ± 23.63 MgC/ha. For this reason, an integrated effort is needed between components for the sustainability of the mangrove ecosystem in the coastal area of Semarang-Demak. Findings in this research are an additional database for the sustainable management of mangrove ecosystems in the coastal area of Semarang-Demak, Indonesia. As in the diagram developed, mangrove ecosystem management needs to always involve the community in mangrove management, stakeholders, and research institutions and universities to monitor and evaluate environmental components so that the existing database can be managed properly and sustainably.
