Scientific reports show that Castilla-La Mancha is one of the Mediterranean regions where the effects of climate change may be particularly important.

The Regional Strategy for Reducing and Adapting to climate change (Spanish acronym: ERMACC), which was passed in 2010 and is currently under review, sets common goals for reducing and adapting to climate change, seeking to guarantee the joint action of the Regional Government to strengthen the effectiveness of the actions that are taken, budgetary efficiency, political coherence, solidarity, co-responsibility and social commitment. Accordingly, it provides a number of measures on both reduction and adaptation.

Climate change Office has been created as a horizontal administrative unit and provides advisory services for regional policies and actions related to climate change.
