Bandung CO2 emissions continue to increase in line with an increase in the Bandung population. Bandung CO2 emissions are generally sourced from the industrial sector, transportation, LPG consumption, animal husbandry, and households; whereas CO2 uptake only comes from vegetation through photosynthesis. CO2 emissions that are too high can have an impact on decreasing air quality and reducing environmental health. Efforts to reduce the rate of CO2 emissions can be done through an approach to suppress CO2 emissions from various emission sources and increase absorption through vegetation cover. This study aims to estimate the amount of CO2 emissions and their absorption in Bandung by implementing a simulation package of CO2 Emission Reduction (PLEC). The simulation package consists of four scenarios, namely (1) substitution of motor vehicle fuel and the application of smart driving techniques, (2) optimization of waste processing in TPST, (3) processing 90% of animal waste into biogas and (4) green space development of 30 % of Bandung City area. Estimated CO2 emission and absorption rates are calculated for the next 10 years (2021-2030) using the STELLA program version 9.0.2. The results showed that without the implementation of the PLEC simulation package the amount of CO2 emissions in Bandung in 2030 was estimated to reach 10,983,666.82 tons, while the application of the PLEC simulation package was 2,361,721.30 tons. Without the application of the PLEC simulation package, the estimated amount of CO2 emission uptake in 2030 was 214,235.11 tons, while the application of the PLEC simulation package was 2,785,703.11 tons. The largest estimate of CO2 emissions after applying the PLEC package in 2030 is thought to come from the household sector (1,246,517.49 tons), followed by transportation (1,000,065.41 tons), industry (109,794.84 tons), energy consumption (3,730), 73 tons) and animal husbandry (1,612.84 tons). It can be concluded that the application of the PLEC simulation package is expected to reduce the level of CO2 emissions in Bandung by 78.5% and can increase CO2 absorption by 1,200.3%.
