Air Pollution Improvement Plans
CSC made an air pollution improvement plan by expanding its investment of NT$44.709 billion between 2020 and 2026 to actively improve air quality. In coordination with the “Air Pollution Control Action Plan” promoted by the Executive Yuan, CSC participates in review meetings on air pollution control and improvement of state-owned enterprises conducted by MOEA quarterly.

Implementation Results
By taking various air pollution improvement measures, CSC reports air pollution emissions quarterly by using continuous automatic monitoring systems (CEMS) in accordance with the relevant regulations of the Air Pollution Control Act.
| Emissions | 2020 | 2021 | 2022 | 2023 | EIA Commitment Limits | |
|---|---|---|---|---|---|---|
| SOx (tons/year) | 4,943 | 5,579 | 4,257 | 4,163 | 34.9 tonnes/day | |
| NOx (tons/year) | 5,822 | 6,593 | 5,603 | 5,209 | 34.6 tonnes/day | |
| Particles (tons/year) | 2,188 | 2,164 | 1,921 | 1,776 | 19.5 tonnes/day | |
| VOCs (tons/year) | 483 | 409 | 356 | 306 | - | |
| Dioxin (g-TEQ/year) | 3.92 | 2.12 | 3.50 | 3.11 | - | |
| Ozone Depletion Potential Values(I) | Total (tons, CFC-11 equivalent) |
8.15x10-2 | 6.03x10-2 | 8.07x10-2 | 7.03×10-2 | - |
- The refrigerants used by CSC, which are subject to the Montreal Protocol, include R-124 (2-chloro-1,1,1,2-tetrafluoroethane) and R-22 (chlorodifluoromethane). The Ozone Depletion Potential (ODP) has been calculated based on this principle since 2015. The coefficients are referenced from the Annex of the Montreal Protocol
- Figures for SOx, NOx, particles, and VOCs include those from both the head office and flux processing plant.
Environmental Monitoring and Testing
The CSC Environmental Monitoring Center oversees six air quality monitoring stations and has two digital boards that display real-time air quality data for the public. For stationary emission sources, 32 continuous emission monitoring systems (CEMS) serve to monitor traditional pollutants emission intensity and quantity, 31 of which have been connected to KSEPB for government supervision. The current average monthly effective monitoring rate of each instrument can reach 95% and above, which complies with regulatory standards.
