This study aims to identify and analyze research that promotes sustainable consumption among university students, understand what areas of consumption were addressed, how consumption was intended to become more sustainable and what results were reported.

A systematic literature review was conducted using the Scopus and Web of Science databases and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology. Main criteria for inclusion were focus on changing the consumption behavior of university students, not just diagnosing them, and that students were directly involved in the efforts.

A total of 1,619 articles were extracted, and 34 were included in the study. These selected investigations conducted between 2012 and 2022 focused on areas of consumption such as food, plastic waste, fashion, energy and water. Sustainable consumption was promoted through training programs ranging from one-hour seminars to full-semester courses, marketing and communication campaigns and direct experimentation and interventions. Most articles reported positive results.

This study is limited to research carried out to reduce current consumption by university students; it does not include research aimed at improving students’ professional skills for promoting sustainable consumption.

This study compiles previous research on reducing consumption by university students in a structured manner according to the consumption area, applied strategy and the results obtained.

This research is unique and will serve as a source of inspiration and consultation for academics and university managers concerned about human consumption. It presents successful projects and strategies that can be implemented in their own universities to make their students’ consumption more sustainable.

With the rapid growth and increased consumption of biofuels worldwide, and the multitude of policy decisions supporting this expansion, growing concerns about the biofuels sustainability have arisen. Therefore, the European project “ITAKA”, aiming at supporting the development of aviation biofuels in an economically, socially and environmentally sustainable manner, has devoted considerable effort to take sustainability into account, in a quantitative and qualitative manner. This paper aims to calculate a robust assessment of a life-cycle greenhouse gas (GHG) for the entire ITAKA value chain.

The calculation for the produced bio jet fuel has been set up using the roundtable on sustainable biomaterials (RSB) European Union (EU) renewable energy directive (RED) methodology, through the online RSB tool. This pathway includes feedstock production, feedstock processing, biofuel production, biofuel distillation and all transport steps involved.

A significant reduction in GHG emissions has been demonstrated, up to 66 per cent emission reduction if one considers a mature pathway for the entire ITAKA biofuel chain.

The camelina oil produced can be sustainable according to RSB and RSB EU RED schemes if the practices defined in the project are applied.

Application of different frameworks (actual vs theoretical) to the ITAKA value chain has aimed at testing and demonstrating the commercial application of the sustainability standards in Europe and the readiness of biofuels in Europe as a major means to decrease GHG emissions in aviation.

The present paper uses Twitter to analyze the current state of the worldwide, Spanish-language, independent publishing market. The main purposes are to determine whether certain Latin American Spanish-language independent publishers function as gatekeepers of world literature and to analyze the geopolitical structure of this global market, addressing both the Europe-America dialectic and neocolonial practices.

After selecting the sample of publishers, the authors conducted a search for their Twitter profiles and located 131; they then downloaded data from the corresponding Twitter APIs. Finally, they applied social network analysis to study the presence of and interaction between the sample of independent publishers on this social media.

The results provide data-based evidence supporting the hypothesis of some literary critics who suggest that in Latin America, certain publishers act as gatekeepers to the mainstream book market. Therefore, Twitter could be considered a valid source of information to address the independent book market in Spanish. By extension, this approach could be applied to other cultural industries in which small and medium-sized agents develop a digital presence in social media.

This paper combines social network analysis and literary criticism to provide new evidence about the Spanish-language book market. It helps validate the aforementioned hypothesis proposed by literary critics and opens up new paths along which to pursue an interpretative, comparative analysis.
