Linde North America, Inc. ("Linde") is committed to the promotion of socially responsible conduct including efforts to ensure that its products are not tainted by slavery or human trafficking. These efforts include the adoption of the Linde Code of Ethics. In our Code of Ethics, we commit to the principles of the Human Rights Charter of the United Nations and to the core labor standards of the International Labour Organization (ILO). We also support the principles of the United Nations Global Compact. Our focus includes a ban on forced labor and the promotion of human rights. All employees as well as our suppliers are expected to know and abide by our Code of Ethics. Our additional core guideline, the Linde Supplier Code of Conduct, also promotes human rights and prohibits forced labor. Our Supplier Code of Conduct clearly articulates the basic principles for supplier conduct when providing goods or services to Linde. Linde's standard purchase orders and purchase contract templates have been updated to include provisions to require Linde suppliers' compliance with the Linde Code of Ethics and Supplier Code of Conduct. We also offer training tools and other materials and guidelines on corporate responsibility to our supply chain management employees. Internal accountability standards for compliance with these values are maintained by Linde. Linde also conducts an annual social responsibility survey which monitors employee and contractor compliance with these stringent Linde ethical standards.
