Implementation of Environmental Protection
Climate change is a major topic of discussion in the United Nations and among governments, societies, and corporate bodies worldwide. This is also the case for VIS. The VIS Corporate Social Responsibility Promotion Committee has incorporated climate change issues into project implementation and promotion. Since 2016, VIS has conducted carbon and water footprint inventories for company products in recent years as the basis for future GHG emissions reduction measures. VIS introduced environmental accounting and the ISO 50001 Energy Management System in 2017 to strengthen the Company's environmental management tools. In 2018, VIS introduced the material flow cost analysis method and ISO 14064- 1 Scope 3 inventory, which have both passed SGS third-party verification. In addition to introducing different analysis projects, VIS has also utilized the analysis results to identify the risks and opportunities brought by global climate change in the three aspects of risk matrix: laws and regulations, weather-related disasters, and influences of other behaviors; moreover, VIS conduct corresponding action plans and measure the effectiveness.
VIS conducts its GHG inventories by following ISO/CNS 14064-1 standards, the Executive Yuan Environmental Protection Administration (EPA) Greenhouse Gas Validation Guidelines, "Greenhouse Gas Emission Inventory Registration Guidelines," and the WBCSD/WRI GHG Protocol, with 100% control to define organizational boundaries (Operational Control Act). The inventory data are 3rd party verified by SGS.
VIS's latest GHG emissions are 721.1 thousand tons CO2e in 2016, 711.1 thousand tons CO2e in 2017, and 787.6 thousand tons CO2e in 2018. The increase in emissions is due to the continuous growth of production. As for the GHG reduction, VIS has installed local scrubbers for treating process gases. The F-gas reduction in the last three years from 2016~2018 are 271.5 thousand tons CO2e, 285.3 thousand tons CO2e and 327.6 thousand tons CO2e, respectively.
VIS's GHG reduction goal is to reduce GHG emissions per unit area of wafer to 20% lower than the 2015 level by 2020; currently, VIS has reduced GHG emissions by 14.7%.
VIS ensures the transparency of its GHG information by disclosing relevant GHG emission and reduction information via various types of channels. VIS performs self-inspection during the disclosure process and obtains external opinions to continue to improve GHG emission. Information disclosure channels include the following:
Since 2005, VIS has utilized third-party verification for annual greenhouse gas (GHG) emissions and submitted annual reports of GHG emission to the Taiwan Semiconductor Industry Association (TSIA) and EPA, Executive Yuan.
Since 2014, VIS has voluntarily participated in the Carbon Disclosure Project (CDP) to disclose climate change-related information on a yearly basis which includes information on GHG emissions and reductions. In addition, we conduct inspections and make improvements on risks and opportunities relating to legal regulations, natural disasters, finance, and business operations. External bodies are able to access relevant information on the CDP website.
Since 2014, VIS has made its annual CSR reports publicly available on the Company's website, which includes information disclosures which are of concern to our customers and investors.
VIS continues to conserve energy within its public facilities. In response to government's ESCO plan, VIS has invested in replacement of large energy-conserving equipment, enhancing some of the UPS equipment efficiency from 94.4% to 99%, increasing energy utilization rate by 4.6% (Note); installed heat pumps on external air-conditioning box in the cleanroom; purchased energy-saving production equipment; and adopted variable-frequency control systems in vacuum pumps of manufacturing equipment to conserve energy. With respect to conserving natural gas, the external dew point temperature has been used to set the optimal operational level of boilers within each plant. All three fabs have obtained ISO 50001: 2011 certification in 2017, and continue to pass SGS third-party certification. The systematic management processes of ISO 50001: 2011 have enabled VIS to identify new opportunities for improving our energy-saving capabilities, thus enhancing the Company's energy conservation efforts. Through continuous implementation of multiple energy-conservation schemes, VIS invests in more energy-conserving measures and responds to national energy conservation goals.
VIS aims to conserve 10% less energy per unit area of wafer by 2020 than the amount consumed in 2015. As of the end of 2018, VIS has reduced energy per unit area of wafer to 31.6% lower than the level of 2015. VIS's energy-conservation measures in 2018 resulted in 21.13 million kWh in reduced electricity consumption, which was an energy conservation rate of 3.2% and translated to NT$46.7 million in savings.
Air Pollution Control
VIS adopts classification at source, and best feasible technology in multiple phases to implement air pollution control. Then VIS processes the pollutant before effectively treating it using high-performance control equipment. The content of pollutant emitted into the atmosphere is less than (or conforms to) the amount specified in government regulations. Based on VIS's annual test results, the concentration and emission of air pollutants were substantially lower than the permitted amount allowed by the EPA of Executive Yuan.
VIS has set the goal for 2020 to reduce VOCs emissions per unit area of wafer by 10% compared to the 2015 level. By 2018, VOCs emission per unit area of wafer has been reduced by 4.7% lower than the 2015 level.
Water Resource Management and Water Pollution Prevention
VIS maximizes the reuse of water discharged from its manufacturing processes. Based on the characteristics of the discharged water, VIS has established over 10 types of water discharge pipes according to water quality and user demands. Recycling systems are used to reduce wastewater discharge and ease the burden on the environment, as well as prevent the use of tap water as refills, thereby conserve water resources.
VIS's water pollution prevention strategy is focused on reducing the generation of pollutants, then recycling and treating water pollutants by using effective equipment to make sure that the quality of discharged water is better than or equal to the standards set by the government. VIS also continued to take measures in reducing the concentration of tetramethylammonium hydroxide (TMAH) and ammonia nitrogen (NH3-N) in water discharges in order to mitigate the harmful effects of water discharge.
VIS has set the goal of reducing water conservation per unit area of wafer to 13% lower than the level of 2015 by 2020. By 2018, VIS has reduced water consumption per unit area of wafer to 25.4% lower than the 2015 level.
Waste Management and Resources Recycle
Waste management at VIS has shifted from the traditional approach of cleaning and disposing of wastes to an integration of resource management. VIS has designated professional technician for waste disposal management, and we consider waste as a valuable resource that must be recycled and reused. To facilitate sustainable utilization of resources, the primary principle of waste management is to reduce the use of processed chemicals, which in turn lowers waste output. Furthermore, we prioritize in the recycle and reuse of waste materials. We view other treatment methods such as incineration and burial of wastes as a last resort.
A waste recycle rate greater than 90% is required for all VIS plants. Monthly plant recycle rate reports are submitted to supervisors and environmental safety committee monitors to track our progress. In the future, we will continue to decrease our use of raw materials, seek qualified recycling organizations, and help these organizations develop advanced waste recycling technologies to achieve sustainable resource utilization, energy conservation, and carbon reduction. With VIS's continued efforts, recycle rates have increased to over 90% over the past five years.
