Universities are critical in developing a sustainable society by mitigating the negative environmental impact of their activities, encouraging sustainable practices in curricula and research, and demonstrating sustainability in all dimensions of their day-to-day activities to local, national, and global communities. However, most research on sustainability in higher education has been limited to specific sustainability factors and has yet to include the broader integration of green practices. The Islamia University of Bahawalpur (IUB), Pakistan, initiated a comprehensive environmental management program, Green Campus Project (GCP), 2021, ensuring sustainability in all university activities to become a green and sustainable university. This research aims to evaluate the different initiatives of the GCP to achieve its targets. The findings suggest that GCP has successfully achieved short-run goals and reduced the ecological deficit per capita (biocapacity per capita—environmental footprint per capita) of the IUB from −6.62 in 2021 to −5.56 in 2022. This reduction may be attributed to a significant increase in digital footprint, renewable energy, reduction in paper use and increased environmental conscientiousness. However, to reduce the ecological deficit significantly, more concentrated efforts are required in green infrastructure, sustainable mobility, and educational technologies in teaching and research.
