The International Air Transport Association (IATA) and the World Sustainable Hospitality Alliance (WSHA) have agreed to strengthen alignment on sustainability between the airline and hospitality sectors. The agreement, signed at the World Sustainability Symposium, will have an initial focus on the procurement of hotel services by airlines. Airlines and hotels face many similar environmental, social, and governance challenges. These include responsible procurement, environmental management, social responsibility, supply chain performance, and increasingly complex sustainability measurement and reporting expectations.
