IDENTIFYING THE METHODOLOGIES AND CHALLENGES IN ESTIMATING SCOPE 3 EMISSIONS OF DELHI TECHNOLOGICAL UNIVERSITY

Abstract
This paper underscores the importance of carbon footprint estimation in Higher Education Institutions (HEIs) as a catalyst for climate change mitigation. We review widely used methodologies (GHG Protocol, ISO 14064, PAS 2050/2060) and recent literature on global and Indian HEI emissions, highlighting electricity and transport as primary emission sources. HEIs function as living laboratories, offering insights into reduction pathways yet facing data, institutional, and policy barriers in Scope 3 emissions, which include waste management and transportation of students and faculty. A case study of Delhi Technological University (DTU) for the year 2024, illustrates campus boundary definition, data collection processes, and persistent gaps. We recommend future measures and recommendations into university governance, stressing that systematic carbon footprint estimation is critical to benchmark impacts and drive emissions reductions aligned with national and global goals.
