Commonly known as the World Heritage Convention, it establishes how the international community as a whole is responsible for
the protection of such heritage and sets out the duties of States Parties in identifying potential sites that may be eligible for inscription onto the World Heritage List and their role in protecting and preserving them.

celebrates its 50th anniversary in 2022, over 1100 sites around the world are recognized as World Heritage - places that are so valuable to humanity that there conservation has been deemed our collective responsibility. Yet many of these exceptional places face increasing pressure from diverse types of development projects within and around the sites. Assessing the impacts of such projects – before deciding to proceed with their implementation – is essential to both prevent damage to World Heritage and identify sustainable options.

The Guidance and Toolkit for Impact The effects or consequences of a factor on the attributes of the heritage place, both in terms of the attributes’ state of conservation and their ability to convey the heritage/ conservation values. An impact is the difference between a future environmental condition with the implementation of a development project, and the future condition without it. Note that for there to be an impact, there must a source of impact (e.g. noise from an industrial site), a receptor or attribute of the World Heritage property A cultural, natural or mixed heritage place inscribed on the World Heritage List and therefore considered to be of OUV for humanity. The responsibility for nominating a property to the World Heritage List falls upon the State(s) Party(ies) where it is located. The World Heritage Committee decides whether a property should be inscribed on the World Heritage List, taking into account the technical recommendations of the Advisory Bodies following rigorous evaluation processes.
When used as a general term, World Heritage refers to all the natural, cultural and mixed properties inscribed on the World Heritage List.
that is affected (e.g. residents living nearby) and a pathway or route by which the harmful action or material is able to reach the receptor (e.g. the air). Impacts can be positive or negative, as well as direct or indirect, current or potential and originating within the heritage place, any existing buffer zone(s) and even beyond it.
