Universities play a critical role in shaping sustainable mobility strategies, especially in urban contexts where the institutional transport system can influence environmental and social outcomes. This study integrates Environmental and Social Life Cycle Assessment (E-LCA and S-LCA) to evaluate the current university transport system from internal combustion engines, diesel, and compressed natural gas (CNG), focusing on the operation and maintenance phases. Also, it compares seven scenarios, including electric, renewable sources, and biodiesel technologies. Environmental impacts were assessed using the ReCiPe 2016 midpoint method, which considers the following impact categories: Global Warming Potential (GWP); Ozone Formation, Human Health (OfHh); Ozone Formation, Terrestrial Ecosystem (OfTe); Terrestrial Acidification (TA); and Fine Particulate Matter Formation (FPmf). The sensitivity analysis explores scenarios to assess the effects of technological transitions and alternative energy sources on the environmental performance. Social impacts are assessed through a Social Performance Index (SPI) and Aggregated Social Performance Index (ASPI), which aggregates indicators such as safety, travel cost, punctuality, accessibility, and inclusive design. Accessibility emerged as the lowest indicator (ranging from 0.61 to 0.67), highlighting opportunities for improvement. Our findings support decision-making processes for integrating sustainable transport strategies into a University Mobility Plan, emphasizing the importance of combining technical performance with social inclusivity.

This study assessed the economic and financial viability of representative smallholder dairy farms (RSDFs) by analyzing two farm types: (1) RSDFs that rely exclusively on family labor and milk receipts, and (2) RSDFs that employ hired labor and obtain income from milk in addition to sales of crops and agricultural by-products. A stochastic simulation based on empirical distributions derived from 44 years of historical data was used to project a 10-year horizon. Results indicate a low-to-minimal probability of decapitalization, an overall outlook of economic and financial viability, and a return on assets between 12% and 22%. Net present value (NPV) was positive for all RSDFs except one; however, in every case, NPV was lower than the opening asset value. Under current economic and policy conditions, RSDFs in the highlands of Mexico appear economically and financially viable through 2033. Family labor was associated with stronger economic and financial outcomes among the small-scale dairy farms evaluated.

This study analyzes the social perception of the mobility system at the Autonomous University of Mexico State. The survey categorizes findings into five key dimensions: accessibility, jobs, mobility and connectivity, safety and public health, and livability. About accessibility (transport services, stops and financial means), the analysis reveals a significant reliance on urban transport 39%, and the Potro Bus service 22%, and perceived efficiency and cost-effectiveness; the stops of mobility service on University community was 1 or 2, and the cost of daily travel was 1.50 USD. The mobility and connectivity (level of satisfaction, punctuality and average distance), around 29% acknowledge the efficiency of the transportation system and economic viability, because is free for students. Safety and public health (accidents, carbon footprint and inclusivity), with 78 % reporting no accidents, and 43% praising the inclusiveness. Moreover, 70% are interested to learn about their carbon footprint associated with transport. The livability (University projects, Urban mobility plans and Technological tools), involves actively educating and engaging in sustainable transportation initiatives with technological and environmental point of view. Additionally, the research introduces the application of Social Life Cycle Assessment methodologies to evaluate the environmental and social impacts of mobility services, aligning with ODS.

Smallholder dairy farms are central to rural livelihoods in Latin America, yet feeding strategies can shift environmental burdens across climate, land, and water dimensions. This study integrated cluster analysis and life cycle assessment to identify methane-related feeding typologies and assess their environmental trade-offs in smallholder dairy farms in the Mexican highlands. Twenty-nine farms from two dairy regions were classified by k-means clustering into two methane-emission-related farm typologies, which were subsequently characterized by their observed feeding profiles: conserved-forage-dominant (Cluster 1, n = 17) and green-forage-dominant (Cluster 2, n = 12). Their environmental performance was assessed with a cradle-to-farm gate life cycle assessment following ISO 14040/14044 and ReCiPe 2016 Midpoint across 18 impact categories. Feed production and ration supply were the main hotspots, contributing 72 to 100% of the total impacts. Global warming potential averaged 2.29 and 2.47 kg CO₂-eq per kg of raw milk in Clusters 1 and 2, respectively. Within the study sample, exploratory comparisons indicated higher marine eutrophication and land use in Cluster 1, whereas Cluster 2 showed higher fine particulate matter formation, terrestrial acidification, terrestrial ecotoxicity, and human carcinogenic toxicity (nominal p < 0.05). These potential trade-offs require validation in larger cohorts and with more geographically representative inventories. These findings show that similar milk outputs can arise from distinct feeding pathways with different environmental trade-offs and that greater reliance on fresh forage does not necessarily imply a more favorable environmental profile. Cluster-based characterization offers a practical basis for improving feed sourcing and ration design in dairy systems facing resource constraints.
