Conclusions. “The following are [the] key principles:

i. in addressing the impacts of climate change on the outstanding universal value, integrity and authenticity of World Heritage properties, the World Heritage community will work in cooperation with other partners that also have responsibility, resources and expertise related to this challenge.

ii. The World Heritage Committee will be an advocate for relevant climate change research, and work to influence and support partners that are mandated and resourced to carry out such research.

iii. World Heritage properties will be used wherever appropriate and possible as a means to raise awareness about the impacts of climate change upon World Heritage to act as a catalyst in the international debate and obtain support for policies to mitigate climate change, and to communicate best practices in vulnerability assessments, adaptation strategies, mitigation opportunities, and pilot projects.

iv. Climate change will be considered in all aspects of nominating, managing, monitoring and reporting on the status of these properties.

v. In considering the threat posed by climate change to the OUV, authenticity and/or integrity of a World Heritage property, the World Heritage Committee will use the existing tools and processes”.

11. “The potential impacts of Climate Change range from physical, to social and cultural aspects. (…). Experience and lessons learned on addressing Climate Change impacts stress the need for using a number of management responses at national and local levels. The World Heritage Convention provides an opportunity to develop strategies to implement relevant actions in respect of cultural and natural heritage properties threatened by Climate Change. Given the complexity of this issue, States Parties may request guidance from the World Heritage Committee to implement appropriate management responses to face the threats posed by Climate Change on their natural and cultural properties inscribed on the World Heritage List”.

13. “Conservation is the management of change, and Climate Change is one of the most significant global challenges facing society and the environment today. The actions that need to be taken to safeguard heritage are threefold:

  • Preventive actions: monitoring, reporting and mitigation of Climate Change effects through environmentally sound choices and decisions at a range of levels: individual, community, institutional and corporate.

  • Corrective actions: adaptation to the reality of Climate Change through global and regional strategies and local management plans.

  • Sharing knowledge: including best practices, research, communication, public and political support, education and training, capacity building, networking, etc.”

15. “It is noteworthy that there are strong links between natural and cultural heritage and the Climate Change issue could be used as an opportunity for the two parts of the Convention to be brought closer together”.

16. “(…) Climate Change is one risk among a number of challenges facing World Heritage sites. This threat should be considered in the broader context of the conservation of these sites”.

6. Encourages all States Parties to seriously consider the potential impacts of climate change within their management planning, in particular with monitoring, and risk preparedness strategies, and to take early action in response to these potential impacts;

10. Strongly encourages States Parties and the Advisory Bodies to use the network of World Heritage properties to highlight the threats posed by climate change to natural and cultural heritage, start identifying the properties under most serious threats, and also use the network to demonstrate management actions that need to be taken to meet such threats, both within the properties and in their wider context;

11. Also encourages UNESCO to do its utmost to ensure that the results about climate change affecting World Heritage properties reach the public at large, in order to mobilize political support for activities against climate change and to safeguard in this way the livelihood of the poorest people of our planet."
