Q1. What are the contributions in this paper?
This paper assesses the potential and cost effectiveness of 20 negative emissions in the joint production system of ethanol and electricity based on sugar cane, 21 bagasse, and other residues in Brazil. 23 This study only considers BECCS from fermentation because capturing such CO2 is straightforward, 24 thus potentially representing a cost-effective mitigation option for Brazil compared to other 25 alternatives.
