According to IEA (International Energy Agency), in 2018 transport represented the second most pollutant sector worldwide, with 25% (8,258 Mt CO2) of total CO2 emissions (33,513.3 Mt CO2) globally; therefore, its decarbonization has become one of the most challenging targets. Bioenergy represented one-tenth of the total primary energy supply worldwide, then it is considered a viable alternative to diversify the worldwide energy mix supply. Thus, second-generation biofuels will potentially play a more significant role in the transport sector. In Mexico, bioenergy represents 5% of total primary energy production. Therefore, this work aims to assess the environmental sustainability of bioethanol production from a second-generation feedstock as sugarcane bagasse. This research considered a novel integrated methodology based on a cradle-to-grave life cycle perspective, including four main stages: i) a systematic literature review, ii) data collection, iii) process simulation of the chemical conversion via gasification, iv) Life Cycle Assessment (LCA) (based on the ISO 14040-44 framework) interpretation, and v) validation of results. As part of the results, under a cradle-to-grave boundary, the carbon footprint was 26,689 kg CO2eq with a defined functional unit of 1,000 L of bioethanol. The majority of the CO2eq emissions were attributed to the bioethanol production with 25.3 % and use in vehicle stages with 68.7 %. As conclusions, the results obtained in this study and comparing with other studies suggest that Mexico has a great potential for producing second-generation biofuels. Nevertheless, plans and actions as scenarios, improvements, and further sustainability assessment, as proposed in this work, need to be considered in future work.TextoengopenAccesshttp://creativecommons.org/licenses/by/4.0INGENIERÍA Y TECNOLOGÍA::CIENCIAS TECNOLÓGICAS::TECNOLOGÍA ENERGÉTICA::FUENTES NO CONVENCIONALES DE ENERGÍAScienceTesis de maestríaRenewable energyBiofuelsBioenergySustainabilityUnited Nations 2030 AgendaClimate changeGHG emissionsTransport sector
