To adapt to the impacts from climate change, we adopted in 2019 the Task Force on Climate-related Financial Disclosures (TCFD) of the Financial Stability Board (FSB) to identify the risks and opportunities from climate change and assess the potential financial impacts in order to establish countermeasures based on the identification results.

In November 2020, we became one of the 1,846 global TCFD supporters.

Factory Smart Energy Management System

Through the IDB’s guidance, we completed the ISO 50001:2018 EnMS and was selected as a demonstration plant in 2019. Then, we continued to apply to the IDB for the Factory Smart Energy Management Demonstration Guidance Program in 2020. Based on the EnMS, we established energy performance indicators and baseline requirements, equipped plant workers with the ability to data collection and analysis and control and management, and discovered the actual application and practice of smart manufacturing and management to provide a reference for top management to take corrective actions.

Through systematization, automation, and visualization, we simplified complicated data management, reduced management labor and costs, and provided a reference for discovering opportunities to improve energy conservation and supervising the improvement in energy performance. In the future, we will find space for energy conservation through data analysis to enhance energy efficiency and develop mechanisms and drives for continual improvement, in order to progressively reduce energy consumption and achieve the national policy for energy conservation and carbon reduction.

  1. The VOCs detection maps: records of VOCs value around the plant, and trace of offsite VOCs movement to understand the air quality around the plant.
  2. The Water Information Dashboard: links to the reservoir water source information. Changes are visualized with the BI for predicting the remaining water content for consumption (in days) and monitoring in-house water consumption, in order to remind staff of potential water shortages and facilitate in-house water dispatch in advance. Currently, we have also planned to improve the cooling water system to progressively enhance the system’s electricity efficiency rate. By integrating with the water information dashboard, we can understand the current water supply condition to reduce water consumption without affecting plant operations.

USIG Building Energy Management Program

Promotion Vision

When the challenges of global warming intensified, we implemented the energy management system in the headquarter building in November 2019 out of our high concern about energy conservation and carbon reduction, hoping to enhance building energy conservation and carbon reduction with more scientific and data-based reasonable management with the system.

Strategic Direction

After implementing the energy management system, through figure analysis and diagnosis, we searched for every possible opportunity for energy conservation and carbon reduction and practiced building and office energy conservation and carbon reduction through four aspects: equipment improvement, operation improvement, management improvement, and awareness education. By changing the concept and attitude of employees, we hope to develop self-awareness and habits of energy conservation and carbon reduction in them.

Lighting fixture improvement was the core topic of 2020. By replacing low-efficiency lamps with high-efficiency LED lamps and standardizing color temperature, we enhanced the luminance of the office area and reduced power consumption by 138,848kWh/year. Thermostats were installed for aircon temperature control and timers were used to adjust the on/off time of aircon compressors to significantly reduce power consumption in winter.

GHG Management

We set organizational boundary for GHG inventory based on the “operational control method.” The organization has 100% of GHG emissions from facilities under its operational control. The emission coefficients are cited from EPA’s GHG Emission Coefficient Management Table V.6.0.4, and the global warming potential (GWP) is reported based on IPCC’s AR5 (2013).

In 2019, we selected “ISO14064-1:2018” as the standard for verification of GHG inventory, and gathered GHG inventory data and established the system in the assistance of external experts for more accurate quantitative data. Therefore, we set 2019 as the base year for USI’s GHG inventory. In 2019, the direct emissions (scope 1) were 26,590tCO2e, indirect emissions (scope 2) were 133,280tCO2e, and the total GHG emissions were 159,870tCO2e.

We will continue to implement energy conservation and carbon reduction. In the future, we will progressively plan the product carbon footprint and assess the scope 3 inventory to effectively review the environmental impact of CO2, in order to achieve win-win for environmental protection and profit-making.

NOTE1: Scope 1 refers to direct GHG emissions from production processes or facilities. The 2018 data presented in the above chart covers only the major emission sources such as fuel oils, natural gas, RTO, and flaring (including emissions from stationary burning of fossil fuel and flaring); in 2019-2020, the data covered major emission sources including stationary burning emissions, mobile burning emissions, process emissions, fugitive emissions, land use changes, and forests.

NOTE2: Scope 2 refers to indirect GHG emissions from indirect sources. In 2018, it was purchased electricity. In 2019-2020, it covered the indirect emissions from input power and input energy.

NOTE3: The electricity emission coefficient is subject to the electricity emission coefficient of the utility electricity business: 0.533 kgCO2e/kWh for 2018 and 0.509 kgCO2e/kWh for 2019-2020.

NOTE4: Data of 2018 was reviewed by Deloitte Taiwan. The data of 2019-2020 was verified according to ISO 14064-1:2018 by SGS, including the trial run emissions of the CBC plant.

Note: The trial run emissions of the CBC plant was included for 2019-2020.
