Different scenarios were developed to explore how these actions can reduce emissions and help achieve carbon neutrality, compared to business as usual (BAU). An economic modelling estimated the socioeconomic costs using the marginal abatement cost model. Adaptation benefits were elaborated for suggested mitigation actions. A credible scenario for carbon neutrality by 2050 The LTS4CN modelling suggests that Cambodia could achieve carbon neutrality in 2050 with the FOLU sector providing a total carbon sink of 50 megatons of carbon dioxide equivalent (MtCO2 e). The energy sector is expected to be the highest emitter in 2050 at 28 MtCO2 e, followed by the agriculture e. The waste and IPPU sectors are projected to emit 1.6 and 1.2 MtCO2 e, respectively (Table 1).
