Greenhouse Gas Inventory and Emissions Management

Since 2021, HD Renewable Energy has conducted comprehensive annual greenhouse gas (GHG) inventories covering Scope 1 (direct emissions), Scope 2 (indirect energy emissions), and Scope 3 (other indirect emissions), demonstrating the company’s strong commitment and proactive response to climate issues. Through scientific and systematic accounting, the company gains accurate insight into its carbon footprint and develops targeted reduction measures, moving steadily toward the ultimate goal of net-zero emissions.

We believe that effective climate action must begin within our own operations. HD Renewable Energy has gradually adopted self-generated renewable electricity and continues to follow a defined carbon-neutrality pathway, setting 2030 as a key milestone for achieving carbon neutrality. For HD Renewable Energy, GHG inventory is not merely numerical disclosure—it serves as a strategic foundation for climate action, enabling the company to maintain competitiveness and leadership amid global climate challenges.

In terms of methodology, HD Renewable Energy follows the ISO 14064-1:2018 standard and adopts the operational control approach to define organizational boundaries. The inventory covers emissions from the following categories:

• Category1： Direct GHG emissions (e.g., fuel consumption from company vehicles, boilers)
• Category2： Indirect energy emissions (e.g., purchased electricity)
• Category3～6： Other indirect emissions (e.g., upstream and downstream transportation, employee commuting, business travel, office supplies)

The inventory covers seven internationally recognized greenhouse gases：
Carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF₆), and nitrogen trifluoride (NF₃).

A notable highlight is the company’s proactive disclosure of Scope 3 emissions. Through a materiality assessment, HD Renewable Energy identified employee commuting and business travel as the major Scope 3 emission sources. In response, the company has implemented a set of low-carbon mobility initiatives, including：

• Shared mobility promotion： Partnership with Uber for Business to encourage shared transportation instead of private vehicles
• Public transport incentives： Transportation subsidies to promote the use of MRT, buses, and other public transit systems
• Travel reduction strategy： Establishing a culture of online meetings to reduce unnecessary business travel

Between 2023 and 2024, despite significant growth in the total number of employees, overall company emissions remained stable, underscoring the effectiveness of these low-carbon policies. This reflects not only HD Renewable Energy’s proactive stance on climate governance but also the maturity and robustness of its internal management systems.

Looking ahead, HD Renewable Energy will continue to strengthen its carbon management capabilities, integrating decarbonization technologies with employee engagement mechanisms. Sustainability actions will not only be demonstrated through measurable indicators but will also become an integral part of the company’s culture and daily operations.
