7.2.3 Carbon reduction and emission reduction process
Metric: University measures towards affordable and clean energy
Have a process for carbon management and reducing carbon dioxide emissions.
Prince of Songkla University (PSU) has established a formal Net Zero Emission Policy B.E. 2566 (2023) to guide the University’s carbon management and greenhouse gas reduction efforts. The policy sets a strategic direction toward achieving Net Zero Emissions by 2030 and provides a framework for managing emissions from university activities.
Managing Direct Emissions
PSU promotes measures to reduce direct greenhouse gas emissions by improving the efficiency of energy and resource use, reducing dependence on fossil fuels, and maintaining building cooling systems regularly to support efficient operation.
The University also promotes lower-emission mobility within and around its campuses through pedestrian routes, cycling, electric vehicles and improvements to transport infrastructure that can help reduce pollution from travel activities.
Reducing Energy-Related Indirect Emissions
For energy-related indirect emissions, PSU promotes a greater share of clean and renewable energy in university operations. The policy encourages the use of clean energy sources that reduce environmental impacts and the expansion of renewable energy to help reduce greenhouse gas emissions.
In 2025, PSU generated 1,216,885.81 kWh of electricity from solar power, helping to reduce dependence on electricity from the main grid and supporting the University’s transition toward cleaner energy sources.
Managing Other Indirect Emissions
PSU’s carbon management approach also covers other indirect sources of greenhouse gas emissions. Measures include improving waste management, working toward Zero Waste to Landfill, improving water and wastewater management, increasing rainwater harvesting and water reuse, promoting environmentally friendly products and supporting environmentally responsible activities across the University.
The policy also includes a commitment to divest from organisations that are heavily dependent on coal and oil, further aligning the University’s financial and operational direction with its low-carbon transition.
Greenhouse Gas Removal
In addition to reducing emissions, PSU promotes greenhouse gas removal through the expansion of green areas and tree planting around university buildings. The policy requires an increase in green space of at least 10% of building areas and encourages additional planting around buildings.
Monitoring Energy Use to Support Carbon Reduction
PSU monitors electricity consumption at both university and campus levels to support energy management and future carbon reduction planning. Total electricity consumption was 79,021,680.00 kWh in 2023, 83,863,600.00 kWh in 2024, and 100,467,532.75 kWh in 2025.
In 2025, electricity use was also monitored separately across the University’s five campuses, providing an evidence base for identifying high-consumption areas and planning further energy-efficiency improvements.
Extending Carbon Management Beyond the University
PSU also supports carbon management beyond its campuses through collaboration with Pattani Province. This cooperation includes the development of area-based greenhouse gas emission databases, pilot renewable-energy projects, expert technical advice and greenhouse gas reduction calculations.
Through this integrated approach, PSU combines policy, energy-efficiency measures, renewable-energy development, sustainable mobility, waste and water management, greenhouse gas removal and emissions-related data management as part of its ongoing carbon management process.
