The objective of the study is to estimate the Carbon Footprint of the National University of Jaen (UNJ), for the period 2021. The direct Scope 1 (fuel consumption) and indirect Scope 2 (electricity consumption) greenhouse gas (GHG) emissions were calculated from CO2, CH4 and N2O produced in 29 administrative offices of the university campus. The methodology used was proposed by the GHG Protocol and ISO 14064-1:2006. For fuel emission factors, the indicators established by the Intergovernmental Panel on Climate Change (IPCC) were used, and for electrical energy: 1.56E-01 tCO2/MWh, 9.70E-06 tCH4/MWh, 1.20E-06 tN2O/MWh, and specific conversion factors established by the Ministry of the Environment (MINAM) were used. The results show that a total of 29.3937 tCO2eq were emitted, being CO2 the predominant GHG (23.1364 t). Scope 1 contributed 15,6827 tCO2eq, occupying the highest participation with 53.35 %.

The aim of this study is to calculate the Carbon Footprint (CF) of one campus of the Instituto Tecnológico Metropolitano (ITM), a higher education institution in Medellín, Colombia. Such calculation was conducted from the perspective of Life Cycle Assessment (LCA), considering and analyzing significant impacts of the ITM on the environment and its relationship with its surroundings derived from its operational activities related to the objectives in its mission statement (education, outreach, and research). The methodology used here for the LCA, the Carbon Footprint calculation, and the compilation of input and output inventories of different subprocesses (that comprise ITM’s operation) observed the requirements and guidelines established in the ISO 14001 (2015), 14040, 14041, 14043, and 14064 standards. According to results the activities that emit the most GHG fall within Scope 1, especially the use of fossil fuels (for the transportation of equipment and ITM employees), with about 69%; and, in Scope 2, electricity consumption contributes 26.8%.

Universities are complex organizations, so when implementing an EMS and adopting strategies, methodologies and programs they must involve the entire university system to minimize the negative impacts on the environment and, thus, lead the search for sustainable or carbon neutral organizations. Carbon Footprint was used as an indicator to measure the sustainability effectiveness of the environmental programs implemented and promoted by the EMS-ITM and how they mitigate the emission of GHGs. The calculation of this indicator was developed following ISO 14040-14044 and ISO 14064, for the ITM-Robledo campus and for the period 2015-2017. The results show the relevance and the reduction in the GHG emission levels achieved by the environmental programs studied, especially by the comprehensive solid waste management program, with which the highest levels of mitigation are achieved.
