Oil palm replanting has faced environmental criticism as it is a source of carbon dioxide (CO₂) emission. The aim of this study was to determine the level of CO₂ emissions and the value of carbon stocks for oil palm smallholders replanting. The measurements were taken using the infrared gas analyser (IRGA) method for CO₂ emission. Non-destructive methods were used to measure carbon stocks for oil palm-stands while destructive methods were used for understorey and intercropped plants. This study shows that there was dynamic of CO₂ emission during the replanting averaging (t CO₂ haˉ¹ yrˉ¹) 28.5 for 28-year-old oil palm, 59.0 for bare land after land clearing, 47.0 for intercropped plants in the vegetative phase, 51.6 for intercropped plants in the generative phase and 42.9 for one-year-old oil palm. It was found that CO₂ emissions were reduced due to the conditions of land coverage and that the reduction in CO₂ emissions occurred not only because of the absorption of CO₂ by plants for photosynthesis but also due to being stored away, as much of the carbon stock (t C haˉ¹) was found in corn (10.2), legume cover crops (7.6), soyabeans (3.5) and natural vegetation (2.8). In 28-year-old oil palm it was found to be at 74.7.
