12.4.1 Publication of a sustainability report

Srinakharinwirot University (SWU) publicly discloses its sustainability and environmental performance through the SWU Annual Report 2025 (Fiscal Year B.E. 2568), which is published on the university website and serves as an institutional sustainability report. Under the LOVES development framework, the section "E – Environment" (pages 113–117) gives a structured, publicly accessible account of the university's environmental performance in 2025, covering green space development as a carbon sink under the "Low Carbon Society" concept, waste segregation and recycling with quantified waste data and avoided CO2 emissions, the reduction of single-use plastic, tap water quality monitoring, and the large-scale introduction of solar energy under the "SWU Net-Zero Campus" plan, together with support for electric vehicle infrastructure (page 118). Together, these elements show that the Annual Report goes beyond financial and academic reporting and provides an integrated public report on SWU's environmental, resource-efficiency and climate-related performance, consistent with the characteristics of a sustainability report.

Development of the University as a Green University (LOVES: E – Environment)

Under the framework of "a high-performance and sustainable organisation", the university aims to manage its physical environment efficiently, giving importance to infrastructure, utilities, transport and landscape, based on the principles of good governance. The university also aims to develop into a Green University and a Digital Transformation Organisation, integrating technology and innovation into management to increase efficiency, reduce the use of resources and build systems that are sustainable in the long term. In fiscal year B.E. 2568 (2025), the university carried out the following work. (Source: SWU Annual Report 2025, p. 113)

1. Environmental Development

1.1 Landscape improvement and green space. The university increased eco-friendly green space and promoted environmentally friendly behaviour to support the goal of becoming a Green University. The area in front of the Faculty of Science and around Building 6 was redeveloped as the "SWU Garden" under the "Low Carbon Society" concept, with the aim of reducing carbon dioxide emissions by increasing carbon sink areas through planting and caring for durable native plant species that use little water and are easy to maintain, and by using environmentally friendly materials and methods at every stage of the landscape work. (Source: SWU Annual Report 2025, p. 113)

The university also improved the landscape of the roundabout to add green space and improve the safety of pedestrian walkways and traffic routes, turned the ground-floor student activity area of the Multi-purpose Building (Building 14) into a green and environmentally friendly space with durable, easy-care plants, and improved the landscape around the university shrine.

1.2 Waste management and plastic reduction. The university installed waste sorting points based on the 4R principles (Reduce, Reuse, Recycle, Refuse) in central areas that are easy to reach, to manage waste systematically, reduce the amount of waste and raise environmental awareness among students and staff. The report discloses waste data for the Prasarnmit Campus in B.E. 2568: (Source: SWU Annual Report 2025, p. 115)

•  Total waste: 205,012.5 kg (data from January to August 2025);

•  Recycled waste: 15,681.50 kg;

•  Accumulated reduction in CO2 emissions: 35,635.19 kgCO2e, equivalent to planting 3,751 trees;

•  Share of waste by type: general waste 67.1%, landscape waste 15.2%, infectious waste 8.6% and recyclable waste 7.6%, with smaller shares of food waste and hazardous waste.

The university also installed automatic water dispensers that count the number of reused bottles, to reduce single-use plastic waste, raise environmental awareness among students and staff, and support sustainable resource management. (Source: SWU Annual Report 2025, p. 115)

1.3 Tap water quality monitoring. To ensure that tap water supplied at SWU Ongkharak meets the drinking water standards of the Ministry of Public Health, the university samples and tests tap water quality every year and monitors water quality from the production process to the point of use. The results for fiscal year B.E. 2568 were all within the standards: residual chlorine 0.70 mg/L (standard 0.2–2.0), colour 5 Pt-Co units (not more than 15), turbidity 0 NTU (not more than 4), pH 7.29 (6.5–8.5) and hardness 60 mg/L (not more than 300).

2. Energy Cost Reduction and Renewable Energy

The university follows its clean energy and energy efficiency policy to reduce costs and environmental impact. (Source: SWU Annual Report 2025, p. 116)

2.1 Solar rooftop at the HRH Princess Maha Chakri Sirindhorn Medical Center. Parts of the buildings of the Medical Center were adapted for a Solar Rooftop System under the "Smart & Sustainable University" concept, to increase the share of clean energy, reduce electricity costs, support the university's Net-Zero Emission policy and develop a model "Green Building". A total of 1,408 solar panels (625 W each) with a capacity of 880.00 kWp were installed on four main buildings: the Faculty of Medicine building (727 panels, 454.375 kWp), the Student Activity and Service Center building (444 panels, 277.500 kWp), and medical student dormitories D (53 panels, 33.125 kWp) and G (184 panels, 115.000 kWp), with a total installation area of 3,935.80 m².

This project is part of the "SWU Net-Zero Campus" development plan, carried out in cooperation with the private sector, such as Banpu NEXT Co., Ltd., and private clean energy companies, towards becoming a Carbon Neutral University. (Source: SWU Annual Report 2025, p. 117)

2.2 Net-Zero Solutions project. This project aims to reduce dependence on external electricity and reduce the university's greenhouse gas (GHG) emissions by installing solar power generation systems in key areas of the university and the Ongkharak Demonstration School, with a total capacity of 5,654.22 kWp in five areas: Faculty of Engineering (Solar Rooftop, 1,149.72 kWp), Plaza building (Solar Carport + EV Charger, 880.88 kWp), The S.W.U building (Solar Carport + EV Charger, 549.12 kWp), SWU Floating Solar (2,574.00 kWp) and the Ongkharak Demonstration School (Floating Solar, 500.5 kWp). The project includes operation and maintenance, preventive maintenance at least twice a year, an annual performance (PR) test and a control room for real-time monitoring. The SWU Net-Zero Solutions project is part of SWU Ongkharak's transition to clean energy, with solar energy as the main source, and is expected to reduce carbon emissions by more than 77 million kgCO2e over 30 years.
