Message from the General Manager
We conducted a materiality assessment to identify the sustainability issues most relevant to our business and stakeholders. Five key topics now guide our sustainability management: Climate Change, Environmental Impact, Labour & Human Rights, Business Ethics and Sustainable Procurement. These topics align operational priorities with stakeholder expectations. While we have made meaningful progress, we recognize that ESG data collection and performance management remain in early stages and will require continued focus.

Three Mgmt. Objectives

Strengthening Governance

The company aims to improve internal ESG governance through clearer policies, responsibilities and management processes, strengthening accountability across environmental management, procurement, human resources, operations and business administration.

Improving Operational Performance

The company seeks to improve sustainability performance through practical action, including energy-efficiency measures, green electricity use, cleaner production practices, employee training, safety management and process optimization.
North Star is committed to integrating ESG considerations into its business development and daily operations. The company monitors a range of ESG-related risks including evolving environmental regulations, supply chain disruptions and climate-related impacts. These factors are integrated into ongoing operational planning. The company’s ESG strategy is guided by the five material topics identified through its materiality assessment and is built on three broad management objectives.

Supporting Long-Term Sustainable Development

The company aims to gradually improve ESG data management, supplier engagement and target setting. The company views 2025 as a foundation year for establishing future direction and performance improvement.

Five Key Sustainable Development Issues

Pollution Prevention and Resource Efficiency
North Star minimises environmental impact through cleaner production, process management and routine environmental controls covering waste handling, emissions control, water saving and energy  conservation.

Green office practices were also promoted during the year, including reduced paper use through digital systems.

Raw Materials and Supply Chain
As noted in the GHG inventory results above, raw materials represent a major part of the company’s environmental footprint.

In 2025, while total steel procurement volume remained broadly stable compared with 2024, the share of lower-carbon / green steel procurement increased by approximately 50%.

Going forward, we plan to increase renewable electricity use, improve energy efficiency, strengthen waste management and pollution control, increase lower-carbon raw material sourcing, and improve environmental data collection and monitoring.

North Star recognizes that sustainability extends into its supply chain. In 2025, the company issued its first Sustainable Procurement.
Policy and Supplier Code of Conduct, establishing clearer expectations for suppliers and business partners and providing a stronger
basis for responsible sourcing, lower-carbon material selection and supply-chain transparency.

Supplier Standards and Expectations

The Sustainable Procurement Policy and Supplier Code of Conduct apply to suppliers, subcontractors and relevant business partners, addressing：

  • Legal compliance
  • Labour and human rights
  • Occupational health and safety
  • Environmental protection
  • Climate change
  • Anti-corruption and fair competition
  • Information security and confidentiality
  • Responsible business conduct

Indicators Under Development

As ESG management matures, North Star intends to improve data collection and disclosure for additional indicators, which may include:

  • Workplace safety performance metrics
  • Broader energy consumption data
  • Water consumption data
  • Waste management and recycling data
  • Supplier ESG implementation data
  • Business ethics and governance-related

training data Because this is the company’s first sustainability report, some indicators are presented as baseline or initial data. Future reporting periods will provide a stronger basis for year-on-year comparison and performance tracking.

Data and Information Security
The Data and Information Security Policy, issued in September
2025, applies to all employees and establishes requirements
relating to:

  • Legal compliance in data and information management
  • Confidentiality and controlled handling of sensitive information
  • Protection of technical documents, customer information and business records
  • Restrictions on unauthorized disclosure or transmission of company information
  • Responsible third-party access controls
  • Record accuracy and protection against data falsification
  • Reporting and investigation of security risks or violations

Reporting Channels
North Star encourages employees and relevant third parties to
report suspected violations of business ethics, compliance rules
or information-security requirements, and seeks to ensure such
reports are handled confidentially and investigated promptly.
The Management Center plays a key role in policy
interpretation, support and oversight.
Future priorities include enhancing training, reinforcing internal
reporting mechanisms and further integrating ethical
expectations into supplier and partner management.
