Supplier Code of Conduct

Latest updated on September 30st, 2023

In accordance with the core concept of sustainable operation, HIWIN has established short, medium and long-term sustainable development goals in three aspects: economy, environment and society (ESG), in response to The Sustainable Development Goals (SDGs) of the United Nations. HIWIN is committed to ensuring that working conditions in its supply chains are safe, that business operations are environmentally responsible and conducted ethically, and that workers are treated with respect and dignity. To this end, HIWIN established this Supplier Code of Conduct (“Code”) and requires our suppliers to operate in accordance with the principles outlined in this Code. In addition, HIWIN also expects our suppliers to hold their suppliers, contractors, and service providers to the standards defined in this Code.

HIWIN will assess its suppliers’ compliance with this Code when making cooperation decisions. Suppliers are expected to fully understand and abide by the Code, and are highly encouraged to contact HIWIN for any questions. It is hoped that through cooperation, communication, HIWIN ESG evaluations, audits, conflict minerals due diligence, and continuous improvement with suppliers, we can achieve a positive cycle in the supply chain, and work together to improve Responsibilities of Social Citizens.

The provisions in this Code are derived primarily from the Responsible Business Alliance (RBA) Code of Conduct and are in alignment with the international standards such as ISO45001, ISO14001, and ISO14064-1.

Suppliers should pay attention to global climate change trends, assess the impact of climate change on their products, services, and operations, and strive to reduce their carbon footprint while enhancing resilience to climate risks. These efforts include, but are not limited to, conducting and disclosing greenhouse gas inventory, consistently promoting energy efficiency and carbon reduction within the organization, assessing environmental risks and opportunities, reducing the consumption of natural resources such as water, actively supporting biodiversity maintenance and forest conservation, implementing no deforestation and dedicating to land conservation, investing in green research and development for a low-carbon transformation, and actively collaborating with upstream and downstream partners to implement climate change adaptation measures.

F1 Greenhouse Gas (GHG) Inventory and Management

Suppliers should quantify the organization's greenhouse gas emissions annually, including carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), nitrogen trifluoride (NF3), and other gases in terms of carbon dioxide equivalents. A GHG inventory should be properly recorded, reviewed, and managed.

F2 Carbon Footprint Reduction

After the annual inventory is conducted, suppliers should track the GHG emission trend, analyze reasons for any changes, and identify the main sources of emissions and areas for energy conservation and GHG reduction. To reduce carbon footprints, suppliers should plan measures for energy conservation and carbon reduction, setting short-, medium-, and long-term goals for implementation. If introducing renewable power is one of the carbon reduction measures, suppliers should fully consider the impacts of the sources of renewable power on the environment, society, and biodiversity and decide on the sources with low adverse impacts.

F3 Proactive Response to Climate Change

E3.1 Suppliers should keep track of potential climate-related risks and opportunities for their products, services, and operations, and should assess, manage, and respond to climate risks appropriately in order to avoid supply chain disruptions. Suppliers should also establish climate governance and put in place units in charge of setting climate change management indicators and reporting climate progress to C-suite executives on a regular basis.

F4 Communication and Disclosure

E4.1 Suppliers should meet HIWIN product requirements for carbon footprints and provide necessary product-specific GHG emission statistics. If there are publicly accessible platforms such as official websites, suppliers should disclose corporate-level GHG emissions, as well as the achievement of energy conservation and carbon reduction goals, on their official websites, if any, or other public platforms every year.
