In our Supplier Code of Conduct and our Supply Chain Policy, we lay down a set of minimum requirements, including on working conditions and equal treatment, that all suppliers must adhere to by signing up to ISS Supplier Code of Conduct or by having in place own policies of at least the same standard as the ISS Supplier Code of Conduct. It also defines our expectations and requirements towards suppliers in terms of human rights emphasising our expectation that suppliers comply with international standards such as the UN Guiding Principles on Business and Human Rights. Human trafficking, forced labour and child labour are explicitly addressed in our Supplier Code of Conduct and our Supply Chain Policy and are subject to requirements to establish and maintain due diligence processes for these severe human rights areas. Our supply chain policies described above are supported by a detailed set of internal procurement standards setting out requirements that our procurement and supplier engagement process must comply with. At the core is our risk categorisation of our suppliers. Our risk categorisation considers the type of goods and services provided, the environment in which goods and services are delivered as well as geographical risks and potential customer impact. From these criteria suppliers are grouped in high, medium and low risk categories, which determines activities undertaken during each supplier lifecycle phase: Vetting, Contracting, On-boarding, Operations and Off-boarding.
