2 Policies Regarding CREDIBILITY of the World Heritage List
2.6 Comparative studies
The World Heritage List is a list of cultural and natural heritage deemed to be of 'Outstanding Universal Value' as defined in the World Heritage Convention. It is established, updated and published by the World Heritage Committee and is drawn from national inventories, further to proposals for inscription made by the respective States Parties.
The Credibility of the List refers to it as a representative and geographically balanced testimony of cultural and natural properties of Outstanding Universal Value.
The Credibility theme includes policies related to the World Heritage List, such as nominations, Outstanding Universal Value, Tentative Lists, the Upstream Process, the Global Strategy or type of property, among others.
Synthesis based on relevant Committee decisions
The World Heritage Committee recommends undertaking a deep comparative analysis in order to demonstrate the Outstanding Universal Value of the property by fully assessing the relative values of the nominated property against other sites (based on Case law on decisions on Nominations).
