Current Situation
The average temperature of the Hsinchu Plant area in Taiwan was 22.39℃ in 2018
Changes to the return period
Changes to the 10 year return period:
- The temperature increased to 23.3℃ (RCP8.5)
- The temperature increased to 23.62℃ (RCP2.6)
Overall Adaptation Plan for the Group
The yearly average temperature is expected to continue to rise. With the extreme heat, outdoor operations will be suspended when necessary, or related laws and regulations will be complied with to implement necessary handling. The indoor temperature is regulated by the air conditioning system and green building designs have been actively introduced to maximize efficiency.
Current Situation
Longest consecutive rainless days in a year during the base period is 39.5 for the Hsinchu Plant in Taiwan.

Overall Adaptation Plan for the Group
The impacts of seasonal droughts are expected to become more severe with the continued effects of climate change. The main production processes of Wistron are heavily dependent on water use. In order to fulfill our corporate social responsibilities, we will continue to improve our water usage efficiency. We have established rainwater recycling systems in new plants and have included short-, mid-, and long-term targets in the routine performance evaluations, in order to reduce the operational water usage of each unit.
Current Situation
According to the base period (1979 to 2003) data, Hsinan Plant in Hsinchu Science Park, the major production location in Taiwan, is situated in a level 4 (level 5 is the highest level of risk) vulnerability area for flooding (combined evaluation of danger, vulnerability, and exposure).

Overall Adaptation Plan for the Group
Flood prevention facilities and designs have been reinforced in every operating location. Alarm and reporting mechanisms have been established to protect employee safety and reduce asset loss.
Adjustment plans for specific assets or plants:
Regarding the newly constructed operating locations, the 24 hour rainfall flooding potential for the local 100 year return period is used for analysis. Appropriate drainage and flood prevention facilities are reviewed and emergency response plans (including typhoon flooding protection plant) are formulated for the various disasters (including typhoons and flooding), in order to reduce the negative impact of potential flooding in the next hundred years. In terms of design, 1. Install plant trenches, water permeable surfaces, and other low water impact facilities to reduce water flow during rain storms. 2. Reasonable rain drainage pipe diameters and drainage gradients are installed according to the calculations of the 24 hour rain water flooding potential during the 100 year return period, in order to prevent ground flooding at the foundation. 3. Increase the height of the foundation and the first floor of buildings to prevent flood water filling the foundation.
Regarding the emergency response measures:
(1) Planned to install rainwater collection systems and rainwater recycling: pools, in order to manage and reuse rainwater.
(2) Installed flood gates (panels) to prevent flood water entering the underground spaces.
(3) Stipulated the water pumping plan. The water pumping equipment is sufficient to drain flood water during continuous rain storms.
