Greenhouse Gas Accounting Approach
In alignment with the Greenhouse Gas (GHG) Protocol and the university’s Pathway to Net Zero, TSUULL continuously monitors its carbon footprint to ensure transparency and accountability in environmental performance.
All emissions within Scope 1 and Scope 2—including energy use, heating, and transportation—are fully accounted for in the University’s annual sustainability reporting. In addition, business travel and commuting emissions are included to represent our fundamental carbon footprint target of achieving Net Zero by 2030.
Further Scope 3 emissions (related to supply chain activities) are assessed under the broader “Net Zero Plus” initiative, targeting zero direct emissions by 2050.
Definitions of Emission Scopes
- • Scope 1: Direct emissions from owned or controlled sources (e.g., gas heating systems, vehicles).
- • Scope 2: Indirect emissions from purchased energy (e.g., electricity).
- • Scope 3: Other indirect emissions from activities not directly controlled by the institution (e.g., waste, supply chain, staff commuting).
Reporting and Monitoring Framework
- • Scope 1 and 2 emissions are monitored quarterly as part of the University’s Climate Action Reports.
- • Scope 3 emissions are calculated annually using updated estimation models.
- • All reporting aligns with the GHG Protocol Corporate Standard, ensuring accuracy and comparability.

Progress and Improvement Measures
Since 2022, TSUULL has implemented stringent carbon management regulations across its campuses.
Key achievements include:
- • Reduction in the number of university shuttle buses from 11 to 9, optimizing travel routes.
- • Limitation of service car use within campus to essential operations only (2 cars in total).
- • Integration of quarterly emission audits under the Climate Plan reporting cycle.
- • Enhanced data collection systems for non-energy emissions (e.g., waste and air-conditioning refrigerants).
These improvements support the University’s long-term objective of achieving Net Zero by 2030 and Net Zero Plus by 2050.
Commitment to Continuous Monitoring
TSUULL will continue:
- • Quarterly reviews of Scope 1 and 2 emissions.
- • Annual public disclosure of emission data through the GHG reporting framework.
- • Collaboration with sustainability partners to implement retrofitting and energy efficiency projects across university facilities.
Through these ongoing efforts, the University aims to minimize its environmental impact and foster a culture of sustainability within the academic community.
