Call for proposals 2021 - Climate sciences and responses HORIZON-CL5-2021-D1-01 Closed!


In line with the Strategic Plan, the overall expected impact of this Destination is to contribute to the “Transition to a climate-neutral and resilient society and economy enabled through advanced climate science, pathways and responses to climate change (mitigation and adaptation) and behavioural transformations”, notably through:

  1. Advancing knowledge and providing solutions in the any of following areas: Earth system science; pathways to climate neutrality; climate change adaptation including climate services; social science for climate action; and better understanding of climate-ecosystems interactions.
  2. Contributing substantially to key international assessments such as those of the Intergovernmental Panel on Climate Change (IPCC) or the European Environment Agency (e.g. European environment state and outlook reports, SOER).
  3. Strengthening the European Research Area on climate change.
  4. Increasing the transparency, robustness, trustworthiness and practical usability of the knowledge base on climate change for use by policy makers, practitioners, other stakeholders and citizens.

Coordination and synergies between activities supported under Destination 1, as well as in other Destinations and Clusters, and in particular complementarities with Cluster 4 and Cluster 6 should be taken into account by planning for adequate resources for co-ordination and clustering activities. Following a systemic approach, Destination 1 concentrates on activities related to climate science and modelling, whereas Cluster 6 supports R&I in the areas covered by Cluster 6, notably on the implementation of climate change mitigation and adaptation solutions.
