Welion New Energy establishes a full chain supply chain due diligence system to ensure compliance with the United Nations Guiding Principles on Business and Human Rights and the International Labour Organization (ILO) The core convention requires the establishment of a comprehensive risk screening checklist for key areas such as environmental protection, labor rights (including child labor prohibition, occupational health and safety), and business ethics, and a risk identification and evaluation mechanism that combines industry characteristics and regional compliance requirements to conduct graded assessments. Through regular on-site audits, data submission verification, and public opinion monitoring, the implementation of suppliers in carbon emission management, labor welfare, anti bribery, and other aspects is dynamically tracked, and a continuous monitoring and improvement mechanism is initiated for non compliant items. In addition, a supply chain responsibility management information disclosure mechanism is established, and a transparent governance mechanism is established to regularly disclose due diligence results to stakeholders and accept social supervision. We are committed to building a supply chain ecosystem that is both resilient and responsible, Promote the coordinated development of commercial value and social value through full process control.
