Mont Blanc Observatory

Mountain areas are among the regions most exposed to the effects of climate change and the Espace Mont-Blanc is a great laboratory for studying the evolution of ecosystems and seeking new adaptation strategies. The Mont-Blanc Observatory allows us to follow and study the evolution of these territories at 360º, and to share best practices in adaptation.

The Mont-Blanc Observatory (MBO) is an internet platform presenting economic, environmental, social and climate data on the three sides of the Mont-Blanc massif, based on 38 indicators. It is a cross-border information and assessment tool, “climate change thermometer”, serving local communities and promoting sustainability and planning policies.

Created in 2013 thanks to the Alcotra AdaPT Mont-Blanc project, the Observatory is now managed by the Fondation Montagne Sûre, in collaboration with the Region of Valle d'Aosta. The Communauté de Communes de la Vallée de Chamonix Mont-Blanc and the Canton du Valais feed the platform with data from their countries.

In 2022, the first report on climate change in the territories of Espace Mont-Blanc has been published, based on the data contained in the MBO. It compares data from the last forty years (1980-2018) to analyze trends in climate change in the massif. Three indicators related to climate change were taken into account in the report: the "Summer days" indicator, which expresses the number of days (per year) when the maximum temperature was above 25°C, the "Frost days" indicator, which is the number of days per year when the maximum temperature was below 0°C, and the “Length of Growing Season”, an indicator sensitive to changes in the biosphere.
