Responsible Units (Governance)

The responsible unit coordinates energy and greenhouse gas (GHG) management, collaborating with facility management, production, quality assurance, procurement, and finance departments to ensure data integrity and traceability.

The key management mechanisms are as follows:

Energy Monitoring Mechanism: Guided by ISO 50001 principles, daily monitoring is applied to production processes, utility systems, and facility power consumption to regularly evaluate energy usage and savings performance.
GHG Inventory Mechanism: Standardized Scope 1 and Scope 2 accounting protocols are established to comprehensively measure fuel combustion, fugitive emissions, and purchased electricity.
Data Verification & Audit: Rigorous data collection, internal control reviews, and third-party verification are conducted to uphold data credibility, ensuring an accurate baseline for decarbonization tracking and ongoing optimization.

Policy Commitments (Strategy)

Energy Efficiency & Process Optimization: Upgrades and replaces HVAC, air compressor, and key production equipment to continuously reduce unit energy consumption.
Process Improvements: Introduces low-energy technologies and thick-film printing processes to simplify manufacturing, reducing energy, chemical, and liquid waste treatment needs.
Renewable Energy Promotion: Optimizes the energy structure by driving solar self-generation/self-use and renewable energy certificate (REC) applications.

Negative Impact (Risk)

Operations continue to consume energy and generate emissions, facing cost pressures from energy prices, carbon fees, and regulations. Failure to respond effectively could impact product competitiveness, disclosure quality, and customer partnerships.

Positive Impacts (Opportunities)

Establishing energy management and verification mechanisms improves data quality and management foundation. Driving energy efficiency and renewable energy measures steadily reduces energy intensity and emissions, boosting supply chain competitiveness and client collaboration.
