Exact, objective and verifiable carbon budget was quantified both for underground peat depletion and above ground biomass change in the degraded peat swamp forest of Central Kalimantan, Indonesia by multi-temporal airborne laser altimetry of ground and vegetation canopy surfaces. In a period of four years between the initial and terminal airborne laser altimetry along the same transects totaling 530 km covering the study area of 5,800 km2, the peat surface subsided an overall average of 33.8 cm, while the vegetation canopy rose by 102 cm, resulting in an overall carbon emission of 46.8 tC/ha/yr from combustive and aerobic decomposition of peat and net sequestration of 1.84 tC/ha/yr by vegetation regrowth.
