Potencial do sequestro de carbono em plantios de dendezeiros para compensar as emissões de gases de efeito estufa no processo produtivo de óleo de palma

Currently, the oil palm plantations are expanding in the Brazilian Amazon, where there are the optimal conditions for their development. The limitation of culture is an important factor for the maintenance of primary areas in the Amazon. Therefore, to know the characteristics of the culture within a productive context it is necessary to apply methodologies that help the executors of the companies to take into account the carbon emissions of the product. Some studies have been adopting methodologies to determine the greenhouse gas emissions emitted in the palm oil production process, through life cycle assessment applications. In this scenario, this work estimated the carbon stocks in the hybrid palm Interspecific (HIE) (Elaeis oleifera cortés x Elaeis guineensis jacq) over 25 years (productive time of the palm) and later to inventory greenhouse gas emissions from the palm oil production process at Marborges SA. The values show to hybrid palm oil, a carbon sequestration of 0.49 Mt CO2 in 25 years and emissions from the productive process are recorded at 0.39 Mt CO2eq. In addition, it was estimated that in the native vegetation areas of the company, the sequestration registered 4.5 Mt CO2, more than the palm plantations. Finally, it can be concluded that within the environmental context the compensation of the gases emitted in the production process of palm oil should happen in pasture areas only or areas without vegetation allied to the maintenance of the native vegetation.
