Another driver of the Brazilian fuel ethanol supply chain: the consumers’ preferences

Performance evaluation of forecasting models based on time series and machine learning techniques: an application to light fuel consumption in Brazil

“…Specifically in the case of demand, most studies conducted aimed at assessing gasoline, hydrous ethanol, or NGV consumption behavior individually in the face of changes in economic variables. This is the case of those elaborated by Cardoso et al (2019), Santos et al (2018), Isabella et al (2017), Gomez and Legey (2015), Barros et al (2014), Du and Carriquiry (2013), Salvo and Huse (2013), Santos (2013), Freitas and Kaneko (2011), Pacini and Silveira (2011), Alves and Bueno (2003), Burnquist and Bacchi (2002), among others. Among the authors who assessed the total demand for light fuels in Brazil (gasoline, hydrous ethanol and NGV together) are those developed by Rodrigues and Bacchi (2017), Costa et al (2017), Figueira et al (2014) and Rodrigues and Bacchi (2016).…”

Classifying the Level of Energy-Environmental Efficiency Rating of Brazilian Ethanol

“…Ethanol is a renewable fuel produced by the fermentation of sugarcane extract and molasses. The product has a lower carbon footprint, is biodegradable, and has greater energy-environmental efficiency (renewable energy) compared to oil due to its sustainability in the production chain with better use of natural resources [4][5][6][7][8][9][10]. Ethanol is one of the main biofuels consumed in Brazil. Biofuel partially (or entirely) replaces fossil fuels in engines (flex vehicles) [11].…”

“…The total emission is compared with that of the equivalent fossil fuel (gasoline, for ethanol), resulting in a final score (Energy-Environmental Efficiency Rating), characterizing the mitigation of emissions. This note generates CBios for biofuel producers and importers; with the decarbonization of the Brazilian energy matrix, there is a mechanism for the commercialization of these CBios linked to the carbon intensity of biofuels [2,12,16,18].The incentive to reduce pollutant emissions in the biofuel chain goes far beyond the use of flex vehicles by consumers [9,11,22], but it is directly linked to decarbonization credits given to biofuel producers and distributors, because although renewable, it depends on how sugarcane is produced [5,8,[23][24][25][26]. Alkimim and Clarke [27] showed that the carbon debt of deforestation in Brazilian biomes for ethanol production was equivalent to 608 Mg CO 2 ha −1 in the Amazon, 142 Mg CO 2 ha −1 in the Cerrado, and 212 Mg CO 2 ha −1 to the Atlantic Forest with the respective return time of 62, 15, and 22 years.…”
