Zurich, 10 September 2026 

ISS Switzerland has once again won the gold medal in the 2026 EcoVadis Sustainability Rating, improving its score by five points, to 86 out of 100 points in comparison to the previous year. This places ISS among the top 5 per cent of companies assessed by EcoVadis. ISS Switzerland has successfully retained its "Leader" status – the highest possible rating – in the separately assessed Carbon Management category.

EcoVadis is one of the world’s leading assessment platforms for corporate sustainability. Its methodology is based on international standards such as the Global Reporting Initiative, the UN Global Compact and the ISO 26000 Guidance on Social Responsibility. It assesses companies across four areas: environment, labour and human rights, ethics, and sustainable procurement.  

Significant Progress in Three of Four Areas

ISS Switzerland showed improvement in three of the four areas assessed. There was a significant eleven-point increase in the rating for sustainable procurement. ISS improved its score by five points in labour and human rights and by four points in the environmental area.

This development is the result of various measures taken over recent years. These measures include the stronger integration of sustainability requirements into the supply chain, the electrification of the vehicle fleet, and programmes to reduce energy and resource consumption in building operations, among others.

 

“Receiving the EcoVadis Gold medal once again proves that sustainability is firmly embedded in our operating promise and in our day-to-day actions. The fact that we were able to improve our score by a further five points from an already high level is due to a strong team effort across ISS. Anyone who, like us, operates hospitals, research sites and transport infrastructure, among other things, must meet the very highest standards both operationally and in the areas of environment, supply chain and working conditions.”

Marc Amstutz, Head of Environment & Sustainability at ISS Switzerland.

 

For customers, the “Gold” rating is proof of this: Anyone who commissions ISS for Facility Services strengthens the sustainability performance of their own supply chain – as evidenced by one of the world’s leading assessment platforms.  

Highest Level in Carbon Management Confirmed

In the separately assessed Carbon Management category, ISS Switzerland once again achieved the highest rating of “Leader,” as it did last year. Among other things, EcoVadis assesses the management of greenhouse gas emissions, reduction targets, measures, and reporting on decarbonisation.

For ISS, this is particularly relevant because of its role in building operations: The company manages more than 15,000 buildings in Switzerland, which enables it to reduce its own environmental footprint while also helping customers lower their energy consumption and emissions.
