Policy Document on Climate Action for World Heritage, 2023 (UNESCO)

World Heritage properties are affected by the impacts of climate change at present and in the future. Their continued preservation requires understanding these impacts to their Outstanding Universal Value and responding to them effectively.

World Heritage properties also harbour options for society to mitigate and adapt to climate change through the ecosystem benefits, such as water and climate regulation, that they provide and the carbon that is stored in World Heritage forest sites. Cultural heritage, on the other hand, can convey traditional knowledge that builds resilience for change to come and leads us to a more sustainable future.

World Heritage properties serve as climate change observatories to gather and share information on applied and tested monitoring, mitigation and adaptation practices. The global network of World Heritage also helps raise awareness on the impacts of climate change on human societies and cultural diversity, biodiversity and ecosystem services, and the world’s natural and cultural heritage.
