All suppliers are required to complete "Vestas' registration and self-assessment questionnaire, that includes a module of the topics in Vestas' Supplier Code of Conduct" (page 3, Due Diligence Processes sub-section).
Vestas has a risk management tool that segments suppliers according to their social sustainability risk. "A high social sustainability risk supplier to Vestas is defined as supplier on which Vestas is dependent and which, is simultaneously, is placed in country that has a high risk of human rights violations" (page 4, Risk within Supply Chain section).
Also, Vests conducts Code of Conducts audits and onsite supplier assessments of its suppliers using an external auditor. For example, the statement states that "In addition to the Code of Conduct audits for direct suppliers, onsite supplier assessments were conducted by an external auditor" (page 4, Risk within Supply Chain section).
The Code of Conduct audit and onsite supplier assessment are not risk assessment methods.
