Peatlands play an important role as carbon pools with one third of the world's soil carbon stored (Joosten & Clarke, 2002). However, peatlands of Southeast Asia have suffered shrinkage due to economic and natural resource pressure, often caused by land-use change and fires. In this work, a comparison of different scenarios related to current land management and aboveground biomass valorization of peatlands was performed. The objective was to compare the global contribution to climate change that could be avoided by means of the biomass valorization and stopping the fires in peatlands. A life cycle approach was usedto compare four scenarios that correspond to current land management on peatlands. These scenarios were: 1) business as usual including current fire occurrence, 2) prospective biomass valorization in drained conditions, 3) prospective biomass valorization in non-drained conditions and 4) peatland restoration. The lifecycle inventories relied on meta-analysis reviews and the ecoinvent database. The total greenhouse gas emissions for the “business as usual”, “biomass valorization in drained conditions”, “biomass valorization in non-drained conditions” and “restoration” scenarios were 150, 20, 0.5and -3 t ha yr of CO2equivalent respectively.The “biomass valorization in drained conditions” scenario made it possible to avoid 130t hayrCO2equivalent in comparison with the “business as usual” scenario and, produced 23t hayrof CO2equivalent more than the “restoration” scenario. The “biomass valorization” scenarios in drained and non-drained conditions were alternatives to control fires in peatlands, maintaining a balance between economic activities and contribution to peat formation
