Energy Management and Response to Climate Change

Chroma have working together with our customers to become a green enterprise
that makes a meaningful contribution to a more friendly Earth.

Climate Change and Greenhouse Gas Management

Chroma remains on top of the GHG emissions at the headquarters and all other company premises. The inventory and results are in accordance with ISO 14061-1:2006. Our GHG inventory system keeps proper track of the status of GHG emissions and feasible solutions for further reduction have also been proposed. An unbiased third-party verification organization was commissioned to verify our inventory process to ensure optimal data quality, obtain more information from our internal GHG inventory, and ensure its validity.   

GHG emissions were calculated according to the operational control approach and using the GWP values from the IPCC Fifth Evaluation Report (2013). The inventory includes CO2, CH4, N2O, CFC, PFC, SF6, and NF3. The GHG quantitative inventory can be separated into two groups with different scopes. The first is direct GHG emission, which includes fixed, process, mobile, and fugitive emissions. The second is indirect emissions from energy that generate electricity and have been purchased externally. 2015 is set as the Chroma base year for GHG inventory and our first scope emissions came to a total of 306.4120 tons CO2e/year (2.92%), and the second scope emissions were 10,185.0928 tons CO2e/year (97.08%) to a combined total of 10,491.505 tons CO2e/year.   

To ensure effective and accurate monitoring of our GHG emission, we have adopted GHG intensity (1 ton of CO2 equivalent/NTD 1 thousand from sales) as a management indicator. Our GHG emissions intensities for 2018-2020 are shown in the table below. The trend graph shows that the intensity of GHG emissions was decreasing year by year.

For other indirect GHG emissions generated by outsourced activities (scope 3), because of the difficulties in data collection and the external supply chain involved, only a qualitative inventory is currently conducted. The major emission sources of Chroma in scope 3 include outsourced operations that are not owned or controlled by the Company, for example outsourced restaurant, transportation vehicles, and waste, as well as operations related to the company, such as employee commuting, business travel, etc.

Power and Fuel Management

GRI 302-1、GRI 302-3、GRI 302-4
The energy used by Chroma is mainly externally purchased power. Other fuels include natural gas used in the restaurant, dormitories, and health center; gasoline for company vehicles; and diesel for generators. The energy statistics of Taoyuan, Hsinchu, and Kaohsiung plants are shown in the table below. No diesel was purchased for generators throughout 2019 and 2020. Total energy use, taken as the total energy intensity, was found to be decreasing year by year.

According to the results of the GHG inventory, the main source of Company electricity is external purchase. This means that electricity saving is listed as a priority issue for the reduction of carbon emission. Chroma has implemented many different energy saving measures, including the replacement of old PCs with low-wattage PCs and the gradual replacement of all public light fixtures across our plants with LED devices. We also do statistical analysis of power consumption at each plant which includes keeping track of the temperature and humidity settings at our plants as well as monitoring air-conditioning. We also disseminate the concept of energy conservation to preserve the resources of our planet. Not only that, we also remind our employees to cultivate the habit of switching lights off whenever they leave a room and to turn off their PC when they leave the office. Good habits like this help conserve energy and reduce carbon emission. Our success in energy conservation and carbon reduction is also evident from a comparison of the graphs of total energy use intensity for the past three years. In 2020, we were able to reduce our total energy use intensity by 10% and we hope to keep this momentum going and bring it down even further.
Replacing the original 76W T8 lamps in the Building B B2 parking lot of the Taoyuan plant with 20W LED lamps saved a total of 3,117 kilowatt-hours of electricity.
Replacing the original 72W T8 lighting fixtures in the Hsinchu plant’s Demo Room with 25W LED lighting fixtures resulted in a saving of 942kWh of electricity.

Water Consumption Management

GRI 303-1
All the water used by the Chroma Taoyuan, Hsinchu and Kaohsiung plants is municipal tap water. It is used by employees and in the plants, mostly by air conditioning (60%). The domestic sewage generated is treated by sewage treatment facilities or is discharged directly to the sewers as required by law. Water is also a vital resource and the reduction of water consumption and the improvement of the efficiency of water usage has become a crucial mission for Chroma. The Company has introduced a number of water-saving measures to ensure effective water management. Monitoring equipment has been installed that checks the quality of air-conditioning cooling water. We have also been disseminating the concept of reducing domestic water consumption. Employees have been installing water-saving gaskets and other water-saving devices with the aim of reducing our monthly water consumption by 3%. This will help to achieve our goals for energy consumption reduction, carbon intensity reduction, and protection of the environment.

The water consumption and intensity statistics for these three years (Taoyuan plant + Hsinchu plant + Kaohsiung plant) are as follows:

In 2020, we analyzed the amount of water used in the plants using the environmental objectives and management plan of the ISO 14001:2015 regulations. The water used for air conditioning accounted for 60% of the water used in the plants. The air conditioning water is now recycled and water quality monitoring equipment has also been installed. The total water consumption intensity in 2020 was 15.4% lower than that in 2019.
