As a result, the concept of measuring greenhouse gases by the management of organizations was established to help reduce the amount of greenhouse gases. This study focuses on the importance of measuring the amount of greenhouse gases or Carbon Footprint by calculating greenhouse gas emissions in units of carbon dioxide equivalent (CO2e) from the activities of the Faculty of Environment and Resource Studies, Mahidol University with data collection of greenhouse gases sources such as electricity and water supply consumption, quantity of wastewater and garbage, and amount of fuels used etc. Then, multiply these data by the emission factors that are recognized internationally. The results showed that a GHGs emission from Faculty of Environment and Resource Studies is equal to 1,091.85 tonCO2e. Sources that emit the most greenhouse gases are the use of electric energy, followed by produced solid waste. Thus, power consumption and the amount of waste created should be reduced with the use of current energy-saving technologies or energy saving campaigns to reduce the power consumption of students and staff including waste classification to facilitate recycling and so on.engMahidol UniversityCarbon FootprintGreenhouse gasesResearch ArticleElsevier10.1016/j.apcbee.2013.05.031
