Global Hospitality Sector Gains New Sustainability Roadmap As WSHA And Diversey Launch Strategic Partnership

The World Sustainable Hospitality Alliance (WSHA) and Diversey, a Solenis company, have entered into a strategic partnership aimed at helping hotels transform sustainability commitments into measurable operational improvements. The collaboration addresses the growing need for hospitality businesses to reduce environmental impact, improve resource efficiency and advance social sustainability while continuing to deliver high standards of hygiene, safety and guest satisfaction.

Through this partnership, hotels will receive support in integrating sustainable practices across key operational areas, including cleaning, hygiene management, laundry services, kitchens and back-of-house functions. By combining WSHA’s sustainability network with Diversey’s technical knowledge and data-driven solutions, hospitality operators will be able to identify opportunities to reduce waste, improve resource management, strengthen water stewardship and monitor sustainability progress in daily activities.

The initiative focuses on moving sustainability strategies beyond long-term goals and turning them into practical actions that can create measurable results. Hotels will have access to expertise designed to help them improve efficiency, optimise operations and build more responsible practices throughout their facilities.

WSHA President and CEO Glenn Mandziuk highlighted that the hospitality sector has an important role in supporting global conservation efforts. He explained that the partnership with Diversey will provide members with advanced technical support and help transform sustainability ambitions into realistic solutions that protect essential natural resources.

Diversey’s parent company Solenis also emphasised the importance of creating practical sustainability solutions that address real operational challenges faced by businesses. Dr Lotta Kanto Öqvist, Chief Sustainability Officer at Solenis, said the collaboration will enable hotel operators to discover new ways to improve resource efficiency, enhance operational performance and progress towards their long-term sustainability objectives.

With sustainability becoming an increasingly important priority for the global hospitality industry, the partnership between WSHA and Diversey aims to help hotels balance environmental responsibility with the everyday requirements of guest service. Diversey’s solutions are designed to support hotels in maintaining high standards of cleanliness, safety and customer experience while reducing resource consumption and improving operational efficiency.

The collaboration represents a wider industry shift towards practical sustainability measures, where hotels are focusing not only on setting environmental targets but also on implementing solutions that deliver measurable improvements across their daily operations.

“Hotel teams need solutions that are easy to implement and reliable in day-to-day operations,” said Anouk Sassen, Regional Hospitality Sustainability Expert, Diversey. “Through this partnership, we can share practical experience with WSHA members and help translate sustainability priorities into improvements that work on property.”

The partnership highlights WSHA’s ongoing commitment to strengthening its Net Positive Hospitality vision by bringing together industry stakeholders and encouraging greater collaboration across the hospitality sector. Through shared expertise, practical guidance and open discussions, the initiative aims to help businesses develop and implement sustainable practices that create long-term positive impacts.

By focusing on knowledge exchange and real-world solutions, the collaboration will support hospitality organisations in understanding how sustainability goals can be integrated into daily operations. The partnership is designed to encourage innovation, improve industry awareness and provide businesses with practical approaches to address environmental and social challenges.

The announcement comes ahead of the WSHA Global Summit, which will be held in Paris on 8–9 December 2026. The upcoming gathering will serve as a platform for hospitality leaders, experts and partners to discuss emerging opportunities, strategic partnerships and operational changes needed to accelerate progress towards Net Positive Hospitality.

The summit will bring together global voices from across the hospitality industry to explore actionable solutions and share experiences that can support a more responsible and resilient future for the sector. Discussions will focus on how collaboration, innovation and sustainable transformation can help shape the next phase of hospitality development worldwide.
