At Wesco, we understand that sustainability stretches beyond energy efficiency and emissions tracking. Truly sustainable business practices must also protect human rights, safeguard health and safety standards and promote environmental responsibility. That is why we require suppliers to comply with the Wesco Supplier Code of Conduct and applicable laws, and we use a risk-based approach to evaluate supplier compliance and sustainability performance.
Wesco is firmly committed to operating with the highest levels of ethics and integrity. The Wesco Code of Business Conduct is the foundation of our global ethics and compliance program, setting forth standards and guidance for conducting business with the highest degree of honesty and integrity. In many cases, the Code requires higher standards of ethical conduct than is required by law.
Protecting the data and systems that support our operations, customers and partners is fundamental to our success.
