ThaiBev conducts annual assessment of all production facilities using the World Resources Institute (WRI)’s Aqueduct Tools to evaluate exposure to water-stressed aMedium–High, High, and Extremely High. Facilities with risk levels categorized as High and Extremely High are prioritized and assessed for mitigation plans.

The result shows that 39 percent of ThaiBev’s production facilities (31 out of 80, including F&N production facilities) are located in areas with High and Extremely High water stress risk levels, posing potential financial or strategic impacts. To address these risks, ThaiBev conducts the Water Sustainability Assessment (WSA) for both surface water and groundwater across all production facilities in Thailand to provide in-depth evaluations of present and future risks and opportunities. The assessment has led to the development of Integrated Water Resources Management Plan (IWRM) for each facility, focusing on implementing a long-term adaptation and mitigation plan. ThaiBev also collaborates with the Hydro- Informatics Institute (Public Organization) (HII) to conduct in-depth studies assessing the risks of floods and droughts under various climate scenarios, integrating findings into operational risk management and community engagement plans. ThaiBev works with its suppliers in water-stressed areas to minimize water consumption. All significant suppliers are also assessed on water-related risks using WRI’s Aqueduct and the Together for Sustainability Initiative, as their operational disruptions could have substantial financial impact on ThaiBev. We have identified 49 out of the 108 locations (45 percent) of key agricultural commodity suppliers as operating in High and Extremely High water-stressed areas.

• To quantify these risks, we identify products dependent on these key agricultural commodities and assess potential revenue loss from water-related supply chain disruption.
• To mitigate risks, ThaiBev works closely with suppliers to secure supply continuity and requires them to track and report their water footprint and intensity annually. Additionally, we monitor and assess our suppliers’ water risks during the rainy season, through daily flood reporting via the CROSS SRM system.

ThaiBev has also established a Sustainable Agriculture Guideline to help suppliers optimize water consumption during their agricultural processes. Our suppliers are encouraged to measure their water consumption, identify opportunities to reduce their usage, conduct water risk assessments using internationally recognized tools, and implement mitigation plans in areas with significant water stress levels.

Since 2022, ThaiBev has collaborated with the Hydro-Informatics Institute (Public Organization) (HII) on the “Water Resource Management for Surrounding Communities” initiative to assess the flood and drought risks in both the short and long term by using the HII’s Water Resource Information System for Sustainable Development. The initiative supports local communities around ThaiBev production facilities located in High and Extremely High water-stressed areas, within a five-kilometer radius of each facility. Through this project, ThaiBev is able to operate its business while creating value for the communities that share the same water sources by devising a mitigation action plan for water-related risks within and outside its operations.

The study process includes:

• Assessing the general condition of the area, the watershed condition, and meteorological and hydrological data—including potential sources of water pollution—to assess the flooding and drought situation, including historical occurrences of such events.
• Analyzing the impacts of climate change on flood and drought issues, including the indices and trends in extreme rainfall data for current and future conditions. Creating a probability map for extreme rainfall in the catchment area and its associated watershed areas around the facility.

The initiative has been implemented at Beer Thai Brewery in Kamphaeng Phet Province, Thanapakdi Distillery in Chiang Mai Province, Simathurakij Distillery in Nakhon Sawan Province, and ThaiDrinks Non-Alcoholic Beverage production facility in Lampang Province, all located in Extremely High water-stressed areas. In 2025, the initiative expanded to include Oishi Trading Wang Muang production facility and F&N Dairies (Thailand) production facility in Saraburi Province. Flood risk in the area is generally low, with only 15 percent of the area classified as high to very high risk due to its location within an irrigation zone. Drought risk remains significant, affecting 50 percent of the area, particularly agricultural land situated outside the irrigation zone. Climate change projections suggest that flood risk may increase in both spatial extent and intensity, while drought risk could decrease, highlighting the importance of adaptive water management strategies.

The study area is more vulnerable to drought than to flooding. Approximately 63 percent of the area is at high drought risk, with nearly 99 percent within a five-kilometer radius considered highly vulnerable due to its location outside the irrigation zones and the predominance of agricultural land. The facility mitigates these risks through a reliable water supply from storage ponds and groundwater wells. Climate change projections indicate increasingly variable rainfall, with potential rises in flood frequency, while drought-prone areas may decrease in size, underscoring the need for proactive water resource planning.

Flood risk is generally low due to effective irrigation management, while drought risk is moderate, with 31 percent of the watershed classified as high risk. The facility maintains a reliable water supply through storage ponds and groundwater wells. Climate change projections suggest stable or slightly reduced drought risks, with minor increases in flood exposure, reinforcing the need for adaptive water and risk management strategies.

To strengthen real-time water monitoring and disaster preparedness and demonstrate ThaiBev’s commitment to water stewardship, enhancing readiness and promoting sustainable water security for both communities and society, ThaiBev supported the installation of 72 automatic telemetry stations in collaboration with the Utokapat Foundation under the Royal Patronage of H.M. the King and the Hydro-Informatics Institute (Public Organization) (HII). This initiative, launched in celebrating the Auspicious Occasion of His Majesty the King’s 6th Cycle Birthday Anniversary, aims to enhance water resource management in northern Thailand’s headwater forests, focusing on the Ping, Wang, Yom, and Nan River Basins across 11 provinces. The telemetry stations collect real-time data on weather conditions, rainfall, and water levels, which are accessible via the National Hydroinformatics Data Center and the ThaiWater mobile application for timely monitoring and disaster response.

To complement the initiative, a workshop on “Monitoring Rainfall and Water Levels from Automatic Telemetry Stations” was organized to provide practical knowledge in using telemetry systems and hydrological data for accurate water situation analysis and disaster preparedness. The training was attended by 40 participants from various ThaiBev business units, including the staff from ThaiBev Situation Room (TSR) and community development teams, strengthening internal capacity for effective water risk management.

• All employees in production facilities received awareness training on water efficiency management.
• All ThaiBev factories in Thailand completed Water Sustainability Assessment for surface water and groundwater.
• Zero water-related incidents since 2012 due to our stringent efforts to control our environmental impacts and our close relationships with surrounding communities.
