Sustainability is based on the concept that the natural, socio-cultural, and economic systems are interconnected.  For revitalization to be truly sustainable, it must include and benefit the local community. Projects that focus solely on attracting tourists and outside investment can lead to gentrification, displacing longtime residents and eroding the social fabric of the area. A successful revitalization project involves active community engagement, where local stakeholders participate in decision-making and benefit from the economic and social changes. Inclusive development ensures that revitalized areas remain accessible to all residents, including affordable housing, public spaces, and opportunities for local employment.

The EU Work Plan for Culture, in collaboration with the UNWTO, developed this concept of sustainable revitalization based on a large metadata study examining sustainable integration, tourism, and heritage preservation under the concept of revitalization. These include involving local communities in tourism planning and deciding which heritage assets should be accessible to tourists versus reserved for local use. They promote sustainability-focused tourism management, considering local needs and resource protection. Education and training are vital to raising awareness among stakeholders and preventing damage to heritage sites. Lastly, integrated, multidisciplinary planning is encouraged, involving all stakeholders in balanced decision-making.
