The Maha Sarakham Waste to Energy Project has undergone an Environmental and Social Due Diligence (ESDD) and a Greenhouse Gas (GHG) Assessment and Climate Change Risk Assessment (CCRA) to identify potential climate-related risks and impacts. There are three main hazard groupings that pose high risks to the Project:

1

Water Availability: The Project Area faces a high risk related to water availability in the future. Water stress is projected to change to Medium under all climate scenarios and timeframes within the Project Area by 2030. Seasonal variability in water availability is projected to remain at a high level under all climate change scenarios and timeframes.

2

Extreme heat: The hazard due to extreme heat is considered high under all climate scenarios and timelines.

3

Riverine flooding: Thailand has a high exposure to flooding, ranking 9th globally, including riverine, flash, and coastal flooding. Coastal flooding is not anticipated for this project due to its inland location. Flood hazards are projected to remain at a medium level, with inundation depths of less than 1.5 meters along several waste transportation routes for a 100-year return period event.
