Análisis de la integración de factores ambientales, sociales y de gobierno corporativo en la administración y toma de decisiones de los bancos del sistema financiero en Colombia
(Universidad Eafit, 2020) Doria Fernández, Andrés David; Vergara Garavito, Judith Cecilia
This paper presents an approach to the advances in environmental, social and corporate governance (ESG) of the banks that make up the Colombian financial system, exposing the theory that relates their corporate performance to good ESG practices. In addition to this identification, the policies that each one applies in terms of ESG were mapped using the following public sources of information: management reports, reports and disclosures, sustainability reports and the Código País implementation report of Superintendencia Financiera de Colombia, among others. Lastly, banks were classified in ranges from highest to lowest compliance or adherence to ESG policies, and an analysis was made of the most profound factors that affect the adoption of ESG policies in the Colombian financial sector.
Análisis de la vinculación al esquema de pagos por servicios ambientales -PSA-de PYMES en el Oriente antioqueño, como modelo gerencial para la sostenibilidad
(Universidad EAFIT, 2025) García Urrea, Jaime Andrés; González Valencia, Alejandro
This research analyzes the connection between small and medium-sized enterprises (SMEs) and the Payment for Ecosystem Services (PES) scheme to promote actions that reduce the impact of human activities. Through the voluntary compensation provided by these companies, the establishment of links with farming communities has been facilitated, where forest conservation is regarded as a cultural activity that also generates income and improves the living conditions of those who protect these ecosystems, which are crucial for regulating water quality and supply. Local management models are identified that contribute to the consolidation and sustainability of payments to the communities that protect these essential resources, while simultaneously preserving farming culture and its practices for forest protection and ecosystem conservation. In this context, the involved companies have implemented an organizational management model that incorporates styles and characteristics aimed at promoting equity toward rural communities as a mechanism of sustainability, integrating it within management practices focused on improving both environmental conditions and the quality of life for farming families who depend on forests and productive systems. This model, driven by SMEs, has enabled the implementation of PES in the areas influenced by their projects by analyzing various environmental, social, and economic structures as a strategy for sustainability and a planning tool, adding significant value to their products, broadening the spectrum of profitability, and benefiting the products and services that these organizations provide.
Cambio climático, convergencia económica regional y efectos espaciales : nueva evidencia empírica para Colombia
(Universidad EAFIT, 2024) Astudillo Mendoza, Carlos Alberto; Aristizábal Tamayo, Juan Manuel
The study analyzes the effects of climate change on economic growth and conditional regional convergence processes in Colombia over the past decade. Using panel models applied to 32 departments over the 2008-2019 period, climate variables are incorporated, and spatial dependence is modeled to capture both the direct and indirect effects of climate on economic growth and interregional convergence. Three main findings emerge from the results: (1) the interaction between the deviation from departmental average temperature and convergence, with an estimated coefficient between -0.03 and -0.044, suggests that temperature variations have more significantly impacted economic growth in the more developed departments; (2) evidence of nonlinearities in the climate-growth relationship, with an optimal deviation threshold of 0.32 °C from the historical average, beyond which negative effects on growth are observed; and (3) the presence of spatial spillover effects, where climatic variations in one department impact the economic performance of neighboring regions. These findings contribute to understanding how climate change influences regional growth and convergence patterns, highlighting the importance of implementing mitigation and adaptation measures that consider both local effects and regional interdependencies, as well as the critical thresholds identified in this analysis (0.32°C).

Desafios de implementación de la regulación trasnacional aplicable en Colombia en materia de cambio climático, derechos humanos y la actividad empreserial
(Universidad EAFIT, 2025) Montenegro Montoya, Alejandro José; Vallejo Piedrahíta, Catalina
This research aimed to identify and describe the transnational regulations on business and human rights related to climate change that are applicable in Colombia. The study began with the recognition that, although there is a growing body of international and regional regulations on these matters, their implementation faces multiple challenges, particularly in contexts like Colombia. Through a dogmatic and historical-legal analysis of international treaties, soft law standards, European and Latin American regulations, and national legal frameworks, the study examined the evolution of transnational law and its capacity to influence corporate conduct in relation to climate change. The research found that, while Colombia has adopted international commitments and domestic regulations, normative gaps, institutional weakness, and a lack of coordination between public and private actors persist. It concluded that these limitations hinder the effective implementation of transnational standards in the country, affecting its alignment with international demands, especially those from the European Union. Finally, the study proposed measures to strengthen Colombia’s legal framework, including regulatory harmonization, institutional capacity building, and the promotion of corporate due diligence as a key tool to address climate change challenges from a human rights perspective.
Desafíos jurídicos en la lucha contra el cambio climático : perspectivas internacionales y nacionales para la participación efectiva del Estado y el sector privado
(Universidad EAFIT, 2024) Bran Rua , Ana Sofía; Vallejo Piedrahíta, Catalina
Climate change is one of the main challenges we face as a society. For mitigating its effects, businesses play an equally fundamental role as countries; however, national and international regulation on this issue is insufficient in relation to the needs. Currently, the legal framework on this matter lacks the necessary specificity to ensure the accountability of the private sector in combating the effects of climate change. This situation allows many companies to evade their environmental responsibilities, compromising global efforts. This document aims to identify legal deficiencies and propose possible solutions to strengthen the legal framework regarding the role of the private sector in mitigating the effects of climate change.
Determinantes de la adopción de tecnologías de agricultura climáticamente inteligente en Colombia
(Universidad EAFIT, 2020) Chinkousky Giraldo, María Antonia; Urrego Morales, María Camila; Muñoz Mora, Juan Carlos
The following work is the product of a research that aims to delimit the determinants in the adoption of Silvopastoral Systems (SSPI) in the Colombian Caribbean region and provide guidance on the public policies that should be followed in Colombia in order to achieve an increase in the implementation of climate-smart technologies. This work seeks to contribute to the efforts to mitigate climate change and at the same time to find tools to address the food challenges associated with population growth trends. The result of the research allowed to identify the socioeconomic and physical factors that encourage the adoption of SSPI in this region, through a Probit type regression.
Development of structural debris flow fragility curves (debris flow buildings resistance) using momentum flux rate as a hazard parameter
(Elsevier B.V., 2018-05-18) Prieto, Jorge Alonso; Journeay, Murray; Acevedo A.B.; Arbelaez, Juan; Ulmi, Malaika; Universidad EAFIT. Departamento de Ingeniería de Producción; Materiales de Ingeniería
Societal risks associated with debris flow hazards are significant and likely to escalate due to global population growth trends and the compounding effects of climate change. Quantitative risk assessment methods (QRA) provide a means of anticipating the likely impacts and consequences of settlement in areas susceptible to landslide activity and are increasingly being used to inform land use decisions that seek to increase disaster resilience through mitigation and/or adaptation. Current QRA methods for debris flow hazards are based primarily on empirical vulnerability functions that relate hazard intensity (depth, velocity, etc.) to expected levels of loss for a given asset of concern, i.e. most of current methods are dedicated to loss-intensity relations. Though grounded in observed cause-effect relationships, empirical vulnerability functions are not designed to predict the capacity of a building to withstand the physical impacts of a debris flow event, or the related uncertainties associated with modelling building performance as a function of variable debris flow parameters. This paper describes a methodology for developing functions that relate hazard intensity to probability of structural damage, i.e., fragility functions, rather than vulnerability functions, based on the combined hydrodynamic forces of a debris flow event (hazard level) and the inherent structural resistance of building typologies that are common in rural mountainous settings (building performance). Hazard level includes a hydrodynamic force variable (FDF), which accounts for the combined effects of debris flow depth and velocity, i.e. momentum flux (hv2), material density (?) and related flow characteristics including drag (Cd) and impact coefficient (Kd). Building performance is measured in terms of yield strength (Ay), ultimate lateral capacity (AU) and weight to breadth ratios (W/B) defined for a portfolio building types that are common in mountain settlements. Collectively, these model parameters are combined using probabilistic methods to produce building-specific fragility functions that describe the probability of reaching or exceeding successive thresholds of structural damage over a range of hazard intensity values, expressed in terms of momentum flux. Validation of the proposed fragility model is based on a comparison between model outputs and observed cause-effect relationships for recent debris flow events in South Korea and in Colombia. Debris flow impact momentum fluxes, capable of resulting in complete damage to unreinforced masonry buildings (URM) in those regions are estimated to be on the order of 24 m3/s2, consistent with field-based observations. Results of our study offer additional capabilities for assessing risks associated with urban growth and development in areas exposed to debris flow hazards. © 2018 Elsevier B.V.

El dilema de la inacción : riesgos económicos y estrategia en el cambio climático
(Universidad EAFIT, 2025) Rios Carmona, María José; Chaparro Cardona, Juan Camilo
This research analyzes the economic incentives that influence international cooperation in response to climate change, using a dynamic game theory model. Through an infinitely repeated game, the strategies of four key actors—United States, China, the European Union, and a coalition of middle-income countries—are evaluated across three rounds (2030, 2040, 2050), incorporating empirical data on GDP, CO₂ emissions, and climate-related costs. The results reveal that although non-cooperation initially prevails, the growing economic impacts of global warming create inflection points where collective action becomes inevitable. This study contributes to the literature by overcoming the limitations of static models, proposing a framework that integrates both asymmetries between countries and temporal dynamics. Furthermore, it incorporates monetary values into the utility function to enable a more realistic and policy-relevant analysis.

Estudio de prefactibilidad para la creación de una granja agrovoltaica (APV) en Paz de Ariporo, Casanare (Colombia) utilizando la metodología ONUDI
(Universidad EAFIT, 2025) Gómez, Carlos Humberto; Tobar Guinand, José Mauricio
This pre-feasibility study evaluates the viability of constructing and operating an agrivoltaic (APV) farm at Las Delicias, located in the village of La Peral, municipality of Paz de Ariporo, Casanare (Colombia). The project proposes a generation capacity of 0,99 MW from solar energy, enabling the production of clean electricity and the simultaneous use of land for agricultural activities beneath the solar panels. The project's viability depends on a detailed analysis of regulatory, economic, and technological factors, as well as its alignment with the region’s energy and environmental needs. To this end, both external and internal factors that may influence its implementation are examined, considering the global energy transition, climate change, the Colombian regulatory framework, and the area's solar potential. Furthermore, the methodology of the United Nations Industrial Development Organization (UNIDO) is used to structure the study and ensure a rigorous and methodologically sound evaluation.
Estudio de viabilidad de una empresa de energía solar en Colombia
(Universidad EAFIT, 2022) Romero Escobar, Luis Felipe; Escalante Gómez, Juan Esteban
The main goal of the present work was to develop a feasibility study for a solar energy company in Colombia using Onudi methodology, in order to assess its relevance at the investment level. The type of research chosen for developing this work, due to its scope and how the information was treated, is descriptive and mixed, respectively, since it contains quantitative research of an economic and financial nature, and qualitative research to describe and interpret the demand and supply of the market business, customer segmentation and the profiles of the distinct positions that the company needs The main finding of this research is that the profitability of the project has been significantly affected by the current economic situation at national and international level due to the pandemic caused by COVID-19. This is because most of the equipment for a solar energy project must be imported, and the devaluation of the Colombian peso against the dollar has carried to the costs of raw materials and maritime transport had considerably increased during the last two years. Finally, the result of this work provided enough reliable information for the partners to decide to continue with the next stage of the project, the execution, and invest the resources that the company requires.
