What are stand-alone Impact Assessments?

This section explains the process of carrying out a stand-alone impact assessment of a proposed action that may impact World Heritage. This stand-alone impact assessment on OUV and other heritage/conservation values is referred to in this Guidance as a Heritage Impact Assessment A Heritage Impact Assessment is an activity-specific or project-level assessment that is focused on identifying and assessing the potential effect of a proposed activity or project on the heritage/conservation values of a natural and/or cultural heritage place. In the context of World Heritage properties, a Heritage Impact Assessment should be particularly focused on identifying and assessing negative and positive impacts on the attributes which convey the Outstanding Universal Value 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.   . This may be appropriate where there is no existing impact assessment system or where the proposed action would not require impact assessment under existing legislation. Examples of proposed actions that may not require formal impact assessment but could still have a significant impact on World Heritage include: widening a road, erecting a visitor centre, making the ground impervious in an area upstream from 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.

This Guidance should be read in conjunction with other guidance on impact assessment.13 Heritage Impact Assessment A Heritage Impact Assessment is an activity-specific or project-level assessment that is focused on identifying and assessing the potential effect of a proposed activity or project on the heritage/conservation values of a natural and/or cultural heritage place.

Impact assessment Impact assessment is the process of identifying, predicting and evaluating the potential environmental impacts of proposed actions prior to major approval decisions being taken and commitments made. It is undertaken for the purpose of avoiding or mitigating adverse impacts, and enhancing beneficial impacts. More generally, impact assessment can be appreciated as a way of thinking and planning that can be applied to all scales of activity. Impact assessment can be applied to development proposals at various levels – projects, plans, programmes and policies.

(see Table 4.1 for a list of the steps and supporting prompt questions). While impact assessment can seem like a linear process, the results of many of its steps will influence the conclusions of earlier steps in an iterative way. In addition, the participation of rightsholders and other stakeholders will need to be considered throughout the process, as will the best ways to avoid negative impacts on OUV through proactive problem solving, including the consideration of alternatives and mitigation measures.
