I have published the first chapter of my doctoral thesis as a review article in Biomass and Bioenergy: "Methodological determinants of carbon intensity in the life cycle assessment of beef tallow biodiesel: A critical review" The paper examines how methodological choices in life cycle assessment — system boundaries, co-product allocation, data sources, land use change accounting — can lead to substantially different carbon intensity results for the same biofuel. The case studied is beef tallow biodiesel, a feedstock of growing relevance in the Brazilian context. The discussion connects directly to a challenge identified by the G20 Energy Transitions Working Group during Brazil's presidency: the lack of methodological harmonisation in carbon accounting is one of the main barriers to scaling up sustainable biofuels and to having their climate benefits recognised in international policy frameworks. This work is the result of the partnership between the University of Brasília (UnB/LEA) and Université Paris-Saclay (CIRED), within the scope of my doctoral research. 🔗 https://lnkd.in/e7W6hJju #Biofuels #LifeCycleAssessment #Biodiesel #EnergyTransition #PhD
