The World Sustainable Hospitality Alliance continues to work with its members to develop the tools, resources, and collaborative platforms necessary to address the climate, human rights, and social challenges facing the hospitality sector today.

Annette Gevaert, SVP Alliances and Strategic Initiatives at EcoVadis said: "Sustainable procurement is no longer just about compliance, it is the foundation of long-term sector resilience. By combining EcoVadis’ global ratings and carbon intelligence with WSHA’s industry leadership, we are giving hospitality organizations a unified pathway to mitigate supply chain risk, safeguard human rights, and accelerate Scope 3 decarbonization, turning shared commitments into measurable, lasting impact across the entire value chain."

Audrey Clavedon, Head of Sustainability Leadership at Sedex, said: “We’re delighted to join WSHA to support our many customers in the industry, and the sector as a whole, to build more responsible and resilient supply chains.”

The announcement comes ahead of WSHA’s Global Summit in Paris on 8–9 December 2026, registration for which is now open. Hosted by Accor, where more than 250 hospitality leaders, investors and sustainability experts will come together to turn ambitious commitments into practical action.

The Summit will conclude with the World Sustainable Travel & Hospitality Awards Gala, celebrating the industry's most impactful sustainability initiatives.
