RE100 and Net-Zero Commitment

Under the global transition toward net-zero emissions by 2050, HDRE continues to advance the low-carbon transformation of its operating locations. In 2025, the Company set a short-term goal for its headquarters locations to achieve net-zero emissions; this goal was partially achieved. Renewable electricity consumption reached 183,636 kWh, accounting for 12.96% of total electricity consumption. Renewable electricity usage reached 90.46% at the Taipei headquarters and 88.05% at the Taichung office.

HDRE continues to increase renewable electricity use through wheeling from self-owned solar projects, Star Trade’s renewable electricity brokerage and wheeling services, and participation in Taipower’s Small-Scale Green Electricity Program. The Company also strengthens energy efficiency through equipment upgrades, smart metering, the Energy Management System (EMS), and the ISO 50001 Energy Management System, for which third-party certification was completed in December 2025.

HDRE has established the following greenhouse gas reduction and net-zero roadmap:

  • 2025 Short-Term Target: Achieve net-zero emissions at headquarters locations — Partially Achieved.
  • 2027 Short-Term Commitment: Reduce emissions by 20% from the base year — In Progress.
  • 2030 Medium-Term Target: Reduce emissions by 40% from the base year — Under Planning.
  • 2035 Long-Term Target: Achieve net-zero emissions across all Taiwan office locations — Under Planning.
  • 2050 Ultimate Target: Achieve net-zero emissions across all operating locations — Under Planning.

To support this pathway, HDRE focuses on three reduction strategies:

  1. Reduce emission intensity through renewable electricity procurement, energy management, and workplace efficiency improvements.
  2. Increase renewable energy adoption through renewable electricity procurement, green power wheeling, and small-scale green electricity programs.
  3. Improve energy efficiency through ISO 50001, smart metering, EMS, and energy-efficient equipment management.

HDRE has completed greenhouse gas inventories for all existing domestic office locations and obtained BSI ISO 14064-1:2018 verification at the reasonable assurance level for four consecutive years. In response to IFRS sustainability disclosure requirements, the Company has initiated a phased transition from ISO 14064-1 to the GHG Protocol framework and plans to expand the inventory boundary to include all entities within the consolidated financial reporting boundary.

In 2025, HDRE reported no material violations of environmental laws or regulations. The Company will continue to expand renewable electricity adoption, strengthen energy management, and improve energy efficiency while progressing toward its 2050 net-zero goal.

Implementation Measures and Performance Outcomes
