Air Pollution Management and Prevention

Management Approach (MA) for Material Topic

Air Quality Impacts Evaluation and Consultation Committee

Due to public concern of air pollutant emission from Mailiao Industrial Park affecting the air quality in Yunlin, Chiayi, and Tainan, we established the "Evaluation and Consultation Committee for Impacts on Air Quality by Mailiao Industrial Park," and actively communicate with stakeholders through industry-academia collaboration and community communication.

Air Pollution and Waste Gas Management

To understand the impacts of emissions on the environment and people's health, we comprehensively adopted the best available control technology (BACT), as well as the world's most advanced process improvement and pollution prevention technologies.

SOx emissions were 2,892,988 kg, NOx emissions were 6,453,009 kg, and TSP emissions were 305,694 kg in 2025. Our SOx, NOx, and TSP emissions in 2025 increased compared to 2024, mainly due to our total production capacity of 30,381 thousand tons in 2025 being higher than our production capacity in 2024. In the future, we will continue to reduce SOx, NOx, and TSP emissions per unit of product install air pollution reduction equipment, make improvements to optimize the level of ammonia injected, and create plans for using low sulfur fuels in our production processes. Per unit of product, our SOx emissions were 0.095 kg/ton, NOx emissions were 0.212 kg/ton, and TSP emissions were 0.010 kg/ton.

The Company began complying with international standards and follows the government's policy to ban the use of halons, CFC-11, and CFC-12 since it was established in 1992. Now, R-134a, R-401a, and R-410a are the main coolants used, and sulfur and benzene contents in gasoline and diesel products strictly follow regulations of the European Union.

VOCs Reduction and Foreign Odor Control

Mailiao Industrial Park is the first of its kind throughout Taiwan that implements cap control. Apart from the pollutants that have already fulfilled environmental assessment requirements, FPCC continues to actively make improvements to reduce the quantity of volatile organic compounds (VOCs). The Company has invested approximately NT$4.04 billion in total into 55 improvement projects as of 2025.

Environmental Violations
We received 3 environmental fines in 2025, none of which were major environmental regulation violations (major incidents involving NT$1 million or more as disclosed on the Market Observation Post System). The fines received were mainly due to discrepancies in the amount of waste materials reported. The Company has already implemented measures to improve verification mechanisms for waste reported online.
