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, a cross-department energy conservation 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

The energy sources at PTI’s various operational sites include electricity, natural gas, diesel, and other energies in the absence of heat supply. These energy sources are supplied by government-owned power plants, public gas utilities, and gas stations, with electricity being the primary energy source. 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 2023, PTI saved a total of 17,240,951kWh, or approximately 62,067.42 joules (GJ), decrease of approximately 8,535 tons of CO2e emissions, equivalent to 22.5 Daan Forest Park’s adsorption of CO2e.

• Electricity used by PTI Taiwan was 673,153,150 kWh (2,423,351 GJ) and electricity intensity was 15.92 kWh / thousand (NTD). The electricity consumption in 2023 decreased by 89,418,690 kWh (321,907 GJ) compared to 2022.
• Natural gas consumption totaled 434,272 m3 (16,814.63 GJ), which was an increase of 125,251 m3 (4,849.61 GJ) compared to 2022.
• Diesel consumption totaled 13,410.07 L (506.32 GJ), which was an increase of 888.17 L (33.53 GJ) compared to 2022.

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. The 2023 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 14,381.30 tonnes of CO2e, indirect GHG emissions (category 2) were 328,260.29 tonnes of CO2e, and the total annual emissions of category 1 and 2 were 342,641.59 tonnes of CO2e. The Category 1 direct GHG emission accounted for around 4.20% of total emissions, while the Category 2 indirect GHG emissions accounted for approximately 95.80% 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 the use of renewable energy, effectively achieving the objective of reducing GHG emissions. In 2023, the GHG emission intensity was reduced by 2.3% compared to 2020 (base year), exceeding the original annual target of 2% reduction.

GHG Reduction to Reach 2050 Net-Zero

In order to avoid the climate crisis caused by greenhouse gas emissions and bring serious environmental impact, PTI respond to carbon reduction initiative, formulate short, medium and long-term carbon reduction targets, implementing energy conservation and carbon reduction, renewable energy construction, low-carbon product innovation, etc. Reduce carbon emissions to meet net zero emissions in 2050.

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 SDGs Goal 13: Climate Action to combat climate change and its impacts.

We implemented 117 energy conservation and carbon reduction measures in the plants and processes to reduce energy consumption and GHG emissions.

Climate Change Response(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 2023, 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.
