Earlier nomination evaluations

Evaluating nominations

The evaluation of nominations is a two-phase process, starting with the newly introduced Preliminary Assessment process as phase I. Preliminary Assessment is a year-long process in which IUCN provides advice directly to States Parties on potential nominated properties under natural criteria (please see our page here for more details). 

The second phase is a circa 15 month process involving IUCN’s international and diverse network of experts. To ensure the credibility of the World Heritage List, it assesses the global significance, management, and integrity of the nominated sites. 

IUCN's evaluations combine field missions, desk reviews and inputs from experts with knowledge of the sites or the natural values they represent. Throughout this process, IUCN draws on the expertise of our six specialist commissions and collaborates closely with the International Union of Geological Sciences (IUGS) and the International Association of Geomorphologists (IAG). All the information collected is reviewed by IUCN's World Heritage Panel to form IUCN's recommendations to the World Heritage Committee.

The Nominations Process

The Nominations Process includes three steps before a potential World Heritage inscription, starting with the creation and revision of Tentative Lists, followed by Preliminary Assessment (compulsory as of 2027) and the formal submission of a nomination dossier. More information on IUCN’s role in these processes can be found here, and on the World Heritage Centre's nominations page. The steps involved in the IUCN evaluation process of nominations in phase II can be seen below:

Thematic studies and gap analyses

Mobilising its wide network of experts, Members and partners, IUCN regularly conducts and updates thematic analyses to help States Parties and interested stakeholders assess the potential for nominating candidate sites to the World Heritage List. 

Thematic studies and gap analyses do not constitute IUCN's recommendations to the World Heritage Committee. Rather they offer guidance on enhancing the role of the World Heritage Convention in protecting globally significant natural areas on the World Heritage List.
