The development of drainage in Acacia crassicarpa plantations in order to control groundwater levels has an impact on CO2 emissions in the atmosphere. The research aims to predict and analyze the amount of CO2 emissions from drainage development activities in the management of Acacia crassicarpa plantations. The study was conducted in Acacia crassicarpa plantations located in Siak Regency, Riau Province. In this research, peat soil samples were purposively taken from three locations near the drainage points. Measurements were taken for bulk density, water content, ash content, organic carbon content, and emissions from the decomposition process due to drainage channel construction. Peat water content ranged from 542.56 to 1021.62%, bulk density ranged from 0.13 to 0.07 grams/cm3, ash content ranged from 0.66 to 2.48%, and carbon content ranged from 56.55 to 57.62%. The construction of a 3-meter deep canal is projected to result in emissions of 273 tons/ha/year.
