INTERNATIONAL HOTELS ENVIRONMENT INITIATIVE Our partnership with International Hotels Environment Initiative (IHEI) is focused on best practices for hotels in biodiversity hotspots. IHEI and CELB are developing guidelines for the responsible siting, design and construction of hotels. more IHEI is working with its members to pilot supply chain management tools, developed by CELB, CORAL and TOI, to encourage good environmental and social practices by marine recreation providers. IHEI members can use these tools to guide their decisions when choosing marine recreation providers who service their customers. more For more information on IHEI, click here.
