  • Mô tả: Biomass has become important as an alternative to fossil fuels and as a means to decrease greenhouse gas (GHG) emissions, particularly in tropical regions such as Brazil. Therefore, the demand for energy crops has increased strongly, and among such crops, palm oil is distinctive because of its productivity and well-developed production techniques. This paper intends to evaluate crude palm oil's GHG balance through a life-cycle assessment approach. This study is based on the average data of an ideal palm oil system in the northern region of Brazil. In the production of crude palm oil, a large amount of CO2 sequestration occurs during the growth of palm oil trees. In contrast, the greatest emissions are biotic CO2, which returns to the atmosphere and emissions from fertilizer production. The GHG balance of an oil palm plantation is approximately −208 kg CO2-equiv./1000 kg crude palm oil per year. •The crude palm oil system fixes approximately 1.1 times more CO2 than it releases.•The main sources of CO2 to the atmosphere are the palm oil residues decomposition.•Synthetic fertilizer production is the largest contributor of inorganic emissions.•The substitution of synthetic fertilizer for compost contributes to GHG reductions.
