This paper presents an innovative experience involving students and professors from diverse backgrounds and regions that was designed to integrate corporate sustainability (CS) knowledge into undergraduate programs. An action research approach was adopted, with the course running over one semester. The course involved 146 students with diverse academic backgrounds from universities across Brazil along with eight professors from Brazil, Chile, and South Africa. The proposed approach provides actionable insights into the integration of sustainability concepts in the higher educational setting, thereby contributing to the development of a more environmentally and socially conscious generation of professionals. The learning outcomes are discussed in the light of the Sustainable Development Goal (SDG) Agenda, particularly SDG 7 (affordable and clean energy), SDG 9 (industry, innovation, and infrastructure), and SDG 13 (climate action). In addition, it is important to highlight that the dissemination of the course's key features can be useful for universities, professors, and researchers engaged in training future professionals capable of addressing real-world problems of innovation and sustainability. By employing an action research methodology and fostering collaboration among students and professors with diverse academic backgrounds and from different countries, including Brazil, Chile, and South Africa, this paper presents a multiregional and interdisciplinary perspective that sets it apart from conventional practices. The emphasis on providing actionable insights and its potential applicability for universities, professors, and researchers involved in training future professionals further underscore its distinctive contribution to education for sustainable development.

Front-of-package food labelling (FOPL) is a mechanism to inform consumers on food nutrients content and risks for health. Each country, within its own institutional framework, defines methods and protocols to formulate rules capable of influencing organizations and the behavior of agents. The paper aims at evaluating the role of some meso-institutions in shaping arenas for policymaking on FOPL based on an exploratory study in Brazil, Chile, and Mexico. A documental analysis and literature review were employed, followed by in-depth interviews. The relevant aspects of FOPL assessed were thresholds for sugar, fats, and sodium; marketing restrictions, and timeframe given for compliance with the new rules. The contribution of this article is to illuminate the way in which meso-institutions operate in a specific context, namely the development of food labelling standards. The focus is to find the rules that allowed the participation of stakeholders in the process of defining normative acts intended to regulate food labelling. The discussion of mandatory FOPL can be interpreted as a struggle to define proper rights for the food industry and the consumer. Meso-institutions, as translators of general normative principles in specific contexts, can encourage or restrict stakeholder participation in policymaking. Besides political arena, the participation can be done in other arenas, such as legislature, regulatory agencies, scientific community, media and public opinion. Institutions that encourage stakeholder participation increase the probability of obtaining widely accepted specific rules. [ABSTRACT FROM AUTHOR]

Committed to achieving carbon neutrality by mid-century, South America faces unique challenges in carbon mitigation due to its distinct socio-economic, technological, and institutional backgrounds compared to developed and other developing economies. Previous research on South America's carbon emissions has limited country and sector coverage and typically adopts a top-down approach that focuses on the overall emissions of an economy, neglecting individual energy sources and emission sectors. Therefore, this paper compiles a comprehensive inventory of CO 2 emissions for South American countries based on a meticulous bottom-up approach and multi-source data integration, followed by a thorough analysis of their temporal evolution patterns and the driving forces behind them. Between 2010 and 2020, South America's overall emissions peaked in 2014 at 1092.3 Mt., led by emissions from oil consumption and from the transport and electricity sectors, and dropped to 865.6 Mt. in 2020, due to the economic fluctuations and COVID-19. Specifically, Brazil was the largest emitter, Chile experienced the most significant increase in emissions, and Paraguay recorded the highest emission growth rate. Generally, expanding population was constant driver of emission growth. High energy intensity led to significant emission increases in Brazil and Ecuador, while elevated carbon intensity was the main driver in Argentina. Energy structure changes played a positive role in most countries to different extents (e.g., much more significant in Brazil than in Chile) but aggrevated emissions in Paraguay and Guyana. Therefore, carbon mitigation strategies should be tailored to each country's unique national circumstances. • During 2010–2020, South America's CO 2 emissions from fossil fuels peaked in 2014. • Transport and electricity sectors comprised over 60% of total emissions. • Brazil was the top emitter, while Chile saw the largest increase in emissions. • Emission patterns and driving factors varied significantly across countries. • Carbon reduction strategies should be tailored to local circumstances.

The occurrence of contaminants of emerging concern (CECs) in environmental systems is gradually more studied worldwide. However, in Latin America, the presence of contaminants of emerging concern, together with their environmental and toxicological impacts, has recently been gaining wide interest in the scientific community. This paper presents a critical review about the source, fate, and occurrence of distinct emerging contaminants reported during the last two decades in various countries of Latin America. In recent years, Brazil, Chile, and Colombia are the main countries that have conducted research on the presence of these pollutants in biological and aquatic compartments. Data gathered indicated that pharmaceuticals, pesticides, and personal care products are the most assessed CECs in Latin America, being the most common compounds the followings: atrazine, acenaphthene, caffeine, carbamazepine, ciprofloxacin, diclofenac, diuron, estrone, losartan, sulfamethoxazole, and trimethoprim. Most common analytical methodologies for identifying these compounds were HPLC and GC coupled with mass spectrometry with the potential to characterize and quantify complex substances in the environment at low concentrations. Most CECs' monitoring and detection were observed near to urban areas which confirm the out-of-date wastewater treatment plants and sanitization infrastructures limiting the removal of these pollutants. Therefore, the implementation of tertiary treatment should be required. In this tenor, this review also summarizes some studies of CECs removal using electrochemical advanced oxidation processes that showed satisfactory performance. Finally, challenges, recommendations, and future perspectives are discussed. [Display omitted] • Occurrence of contaminants of emerging concern (CECs) in Latin America. • Pharmaceuticals, pesticides and personal care products are the most assessed CECs. • The presence of CECs were predominantly observed in close proximity to urban areas. • Electrochemical technologies are an important alternative for CECs elimination.
