Background

Horizon Europe is the EU's ambitious research and innovation programme for 2021-2027, with a budget of EUR 95.5 billion. CINEA runs parts of the programme targeting energy, climate action and mobility research actions, grouped into Cluster 5. 

The overarching driver for this Cluster is to accelerate the twin green and digital transitions and associated transformation of our economy, industry and society with a view to contributing to the EU reaching its climate goals, and increasing energy resilience.
