GHG Management

Energy and Carbon Reduction

FENC enhances energy management with various reduction measures to curtail carbon emissions and mitigate global warming.

Measures and Performance in Energy Saving and Emission Reduction

FENC’s efforts in promoting energy and emission reduction measures continued in 2024 with the implementation of 94 energy and emission reduction projects, which averted 70,188 tCO₂e in GHG emissions. Equipment improvement was the primary focus, among which was the replacement of dated air compressors. The secondary focus was on the enhancement of energy efficiency through production and equipment improvement.

2024 Energy Saving and Emission Reduction Projects

Energy Saving and Emission Reduction Project in 2024

	GHG Emissions Avoided (tCO₂e)
	Scope 1	Scope 2	Total
Project of Production Improvement	4,496	4,537	9,033
Project of Equipment Improvement	0	6,047	6,047
Project of Energy Management	0	17,923	17,923
Project of Low-Carbon Fuel Alternative	340	7,508	7,847
Project of New Renewable Energy Source	29,337	0	29,337
Total	34,173	36,015	70,188

Note:
1. The estimate of energy efficiency is compared against the energy consumption with original production process and equipment prior to project implementation.
2. Scope 1 emission sources are coal, coal-water slurry, and natural gas; scope 2 emission sources are purchased electricity and purchased steam.
3. The emission factor of each energy source is based on the externally verified emission factor from each production site, including plant-specific / mass balance factors and those released by the local government.
4. GHGs avoided include CO₂, CH₄ and N₂O.

Energy Saving and Emission Reduction Project Highlights in 2024

Production Site	Production Site
Hsinpu Chemical Fiber Plant	The temperature of the chilled water supply has been adjusted for the higher setting gradually through equipment improvement. With the rise of each degree Celsius, the electricity consumption drops by 3%. The aluminum alloy fan blades have been replaced with high-efficiency fiberglass reinforced plastic blades, which saves 10% to 25% in electricity consumption. The fixed-frequency chillers has been replaced with low-carbon magnetic bearing chillers to improve efficiency. The waste heat recovery system has been installed for the condensing unit, which replaces electricity as the energy source. The residual heat is recovered during production to evaporate the refrigerant, such as water. Once inside the condenser, the evaporated refrigerant is condensed into chilled water. The above measures are averting approximately 7,000 tCO₂e in GHG emissions each year.
FEIW	The cotton suction system of the spinning machine has been optimized. The structure and weight of the fan blade have been upgraded, the suction function added and the roving frame modified, which have improved energy efficiency and reduced energy consumption, translating to a 3% cut in carbon emissions per year.
FEPV-Knitting and Dyeing Plant	The plant installed inverters on the pump motors of the wastewater system and replaced dated equipment with high-efficiency motors. The plant also improved the stenter without incurring any costs. These measures averted a total of 2,153 tCO₂e of GHG emissions in 2024.

A total of 21 energy and emission reduction projects from 2024 are still underway. Once completed, they are expected to cut carbon emissions by 43,075 tCO₂e annually
