Resumo: Abstract: The agricultural sector contributes with over 30% of the greenhouse gas (GHG) emissions of the Brazilian economy (MCTI, 2023). To offset part of these emissions, the application of biochar in the field (Fig. 1) has been promoted as a promising method, due to suitable cost and logistics. Potential benefits of biochar as a carbon removal technique include the sequestration of carbon in the soil and reduction in N2O emissions (Grutzmacher etal., 2018). The sugarcane production chain presents a good fit for biochar use in Brazil. In addition to a planted area of 8.3 million hectares and a volume of 653 million tonnes of sugarcane harvested in the 2023/24 season, sugarcane production generates large amounts of bagasse (10.4 dry tonne/ha.yr) and straw (2.9 dry tonne/ha.yr) (Silva et al., 2019) as residues, which can potentially be used to produce biochar via pyrolysis (Fig. 1). In this study, we assessed the potential use of biochar, produced from sugarcane residues, to offset the lifecycle emissions of the sugarcane production sector in the state of São Paulo (largest producer in Brazil).
