Climate change and energy are already important issues that the whole world must jointly deal with. PTI, through its Environment, Safety and Health Committee formed by top-managers and representatives from respective departments, is responsible for stipulating, coping with, and implementing related issues on environmental sustainability and climate change. Moreover, an energy-saving cross-department task force consisting of staff from factory affairs, equipment, production, and environmental safety is gathered to contribute to the efficiency of resources. Besides creating energy-saving performance indicators, feasible energy proposals are introduced and by validating the performance of energy-saving proposals, it helps persistently and effectively reduces energy waste and consumption.

Energy Management

In each of PTI's locations, only electricity from public power plants operated by the government is used, not fuels, heat or other forms of energy. PTI has implemented energy management measures to analyze energy consumption and efficiency. To materialize our energy conservation efforts, all of our plants have received the ISO 50001 energy management system certification. PTI has introduced green building design into the construction of new facilities, in order to reduce energy and resource consumption. Our equipment is also equipped with environmentally friendly refrigerants containing low greenhouse effect potential. High-performance motors (IE3 or higher) have been installed for the rotating component. Moreover, we continue to replace older equipment to increase energy efficiency.

In 2022, PTI saved a total of 11,435,224kWh, or approximately 41,166.81 joules (GJ), decrease of approximately 5,821 tons of CO2e emissions, equivalent to 15Daan Forest Park’s adsorption of CO2e.

• Electricity used by PTI Taiwan was 762,571,840kWh (2,745,259 GJ) and electricity intensity was 14.47kWh / thousand (NTD). The electricity consumption in 2022 increased by 11,593,120 kWh (41,735 GJ) compared to 2021.
• Natural gas consumption totaled 309.21m3 (11,965.02 GJ), which was an increase of 195,726m3 (7,578.34 GJ) compared to 2021.
• Diesel consumption totaled 12,521.90L (472.78 GJ), which was an increase of 426.47 L (16.10 GJ) compared to 2021.

GHG Inventory

PTI has referred to ISO 14064-1: 2018 GHG inventory protocol, as well as guidelines established by other domestic and foreign organizations for managing GHG inventories. Furthermore, we have conducted climate change risk analysis based on the risks and opportunities defined by TCFD, and formulated response measures to reduce potential impact.

PTI referenced inventory guidelines of domestic and international institutions such as ISO 14064-1:2018 and the GHG Protocol to establish greenhouse gas inventory and management procedures. The 2022 PTI Taiwan GHG emissions data consists of actual inventory checks performed at respective plants. The data encompasses operation-related direct GHG emission sources (Category 1), energy indirect GHG emission sources (Category 2) and other indirect GHG emission sources (Category 3 to 6). Direct GHG emissions (category 1) were 14,452.871 tonnes of CO2e, indirect GHG emissions (category 2) were 377,208.717 tonnes of CO2e, and the total annual emissions of category 1 and 2 were 391,661.588 tonnes of CO2e. The Category 1 direct GHG emission accounted for around 3.69% of total emissions, while the Category 2 indirect GHG emissions accounted for approximately 96.31% of total emissions. This is predominantly generated by the use of external purchased electricity. Consequently, PTI’s GHG reduction strategy focuses on energy consumption management and energy savings, setting an energy-saving goal of 1% per year to effectively achieve the objective of lowering GHG emissions.

GHG Reduction

PTI actively organizes activities related to energy saving and GHG reduction. Each year, energy conservation goals are set and electricity consumption efficiency is enhanced, while related incentives are provided to reward supervisors and employees that are engaging in energy conservation. We implement carbon reduction projects that are measurable, reportable, and verifiable, and these are linked to SDG 13: Climate Action to combat climate change and its impacts.

In 2022, PTI Taiwan reduced the use of electricity by about 11,435,224 kWh, equivalent to a decrease of approximately 5,821 tonnes of CO2e note emissions. We also implemented 84 energy conservation and carbon reduction measures in the plants and processes to reduce energy consumption and GHG emissions.

Carbon Management(CDP Disclosure)

In response to the Paris Agreement to limit global warming to within 2 degrees, PTI has committed to developing a Science Based Target (SBT). As part of the "CDP Commit to Action" initiative, CDP has actively participated in the CDP Investor Questionnaire and the CDP Supply Chain Program since 2011. Information is provided on PTI's climate change governance, strategy, risk identification and opportunity analysis, as well as GHG emissions, reduction targets and performance. In 2021, PTI received a CDP rating of B, which corresponds to the Management level. In the future, PTI will integrate the financial disclosure of climate change into the CDP evaluation and management, and is actively purchasing renewable energy certificates and installing renewable energy equipment in order to achieve the goal of GHG reduction.
