Sustainability

Our Supplier Sustainability Engagement Programme for Climate Action

ISS is strengthening the way we work with suppliers to support our Net Zero trajectory and increase transparency across our value chain. Our Supplier Sustainability Engagement Programme focuses on top-spend suppliers responsible for roughly 36% of ISS’s Scope 3.1 emissions. As a mandatory requirement, we expect these suppliers to adopt Science Based Targets, report to CDP, cascade sustainability requirements to their own supply chains, and provide verified product carbon footprints to ISS before 2030. We target that by the end of 2026, 32% of our global spend will be with suppliers who have SBTi targets set.

As part of the programme, in 2024 we introduced a structured process including annual sustainability surveys, gap-closing plans, and targeted trainings on ISS environmental expectations, SBTi-aligned decarbonisation, renewable energy, and Life Cycle Assessment (LCA). The combined response rate for the 2024–2025 sustainability surveys was 87%, while the training materials have reached 100% of suppliers in scope of the programme, with an average of 65% joining the live sessions in 2025.

Regardless of annual purchasing volumes, we encourage all suppliers to review the training materials to understand how their climate actions directly support ISS’s decarbonisation pathway, and to follow sustainability principles, which account for 20% of tender evaluation weighting. Through this collaborative and transparent approach, ISS aims to accelerate progress and meaningfully reduce environmental impacts across our global supply chain.
