The Company uses purchased electricity as a main power source but also uses fuel such as natural gas for cafeterias, dormitories and the health center. Company cars run on gasoline and diesel is used for generators.

Chroma HQ (including the Huaya Plant), Hsinchu Branch and Kaohsiung Branch are located in Hua Ya Technology Park, Hsinchu Science Park, and Nanzih Export Processing Zone respectively. None are located in a protected area. No water from any protected area or watersheds is used, Municipal potable water is the single water source. Our manufacturing process is characterized by assembly and tests and water consumption is low. Most water consumption is for domestic use by employees and some is used by peripheral equipment, particularly for air conditioning. We have no significant environmental impact on water sources or the watershed ecosystem, and did not withdraw the water from water-stressed areas. The generated domestic sewage is processed by appropriate sewage processing facilities or discharged directly into the sewage system pursuant to the law. However, in addition to saving electricity, we recognize that water is an invaluable resource and take measures to reduce water consumption and enhance the efficiency of water use. One way we do this is by a rainwater collection system at the HQ building. Sedimented rainwater is used for irrigation and this effort plays a role in water protection and conservation.

We mainly use purchased electricity, and electricity conservation is a Company priority for carbon reduction. We set ESH targets and introduced several energy conservation measures, including aircon energy conservation improvement for Chroma HQ (including the Huaya Plant) and energy-efficient lamp replacement at the Hsinchu and Kaohsiung branches. The effectiveness of the changes at the Kaohsiung Branch were the most significant.
