Our university’s total greenhouse gas (GHG) emissions amounted to 1,626,088.667 kg CO2e during the 2024–2025 reporting period. The emissions were calculated using the GHG Protocol Corporate Standard methodology and emission factors from the United States Environmental Protection Agency (EPA) and the Intergovernmental Panel on Climate Change (IPCC) guidelines. The data for these calculations were gathered from our university records and a university survey.

The emissions were categorized into three scopes, as follows:

1. Scope 1 Emissions: Direct emissions from the university’s activities, including refrigerants and waste disposal. These amounted to 67,935.247 kg CO2e, representing approximately 4.2% of total emissions.
2. Scope 2 Emissions: Indirect emissions resulting from the university’s electricity consumption. These amounted to 1,466,816.26 kg CO2e, representing approximately 90.2% of total emissions.
3. Scope 3 Emissions: Other indirect emissions, including waste generated and commuting-related activities. These amounted to 91,337.16 kg CO2e, representing approximately 5.6% of total emissions.

Compared to the previous reporting year total of 1,739,270.979 kg CO2e, the 2024–2025 result shows an overall emissions reduction of approximately 6.5%.

It is essential to note that the largest share of emissions continues to come from purchased electricity. Therefore, the university’s main carbon reduction priority remains improving energy efficiency, optimizing electricity consumption, and strengthening the use of low-carbon energy solutions. At the same time, further reductions can also be achieved through improved waste management and sustainable campus practices.

TSUE will continue monitoring its greenhouse gas emissions, refining its institutional carbon accounting approach, and implementing practical mitigation measures to support long-term environmental sustainability and climate action.
