Call: Carbon Dioxide Removal (CDR) approaches

Acronym HE-CL5-D1
Type of Fund Direct Management
Description of programme
"Horizon Europe - Cluster 5 - Destination 1: Climate sciences and responses for the transformation towards climate neutrality"

Europe has been at the forefront of climate science and should retain its leadership position to support EU policies as well as international efforts for a global uptake of climate action in line with the Paris Agreement and the Sustainable Development Goals (SDGs), including biodiversity objectives. Advancing climate science and further broadening and deepening the knowledge base is essential to inform the societal transition towards a climate neutral and climate resilient society by 2050, as well as towards a more ambitious greenhouse gas reduction target by 2030. It will involve research that furthers our understanding of past, present and expected future changes in climate and its implications on ecosystems and society, closing knowledge gaps, and develops the tools that support policy coherence and the implementation of effective mitigation and adaptation solutions. Due to the inherent international character of this subject, international collaboration is encouraged for topics under this destination.

The activities implemented under this section will enable the transition to a climate-neutral and resilient society and economy through improving the knowledge of the Earth system and the ability to predict and project its changes under different natural and socio-economic drivers, including a better understanding of society’s response and behavioural changes, and allowing a better estimation of the impacts of climate change and the design and evaluation of solutions and pathways for climate change mitigation and adaptation and related social transformation.

This Destination contributes directly to the Strategic Plan’s Key Strategic Orientation C ”Making Europe the first digitally enabled circular, climate-neutral and sustainable economy through the transformation of its mobility, energy, construction and production systems” and the impact area “Climate change mitigation and adaptation”.

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.

Description of call
"Carbon Dioxide Removal (CDR) approaches"

Expected Outcome

  • Support climate policies through an enhanced understanding of existing and emerging carbon dioxide removal options in terms of their technical readiness, key requirements (land and other resource needs, geographical and geological constraints, primary energy needs, etc.), short- and long-term sequestration potential, permanence, impacts (environmental, social, health, resource depletion, etc.) including potential co-benefits.
  • Support climate models and integrated assessment models through an improved parametrisation of these technologies and solutions, allowing their better integration into pathways and strategies and broadening the carbon dioxide removal technology options that can be numerically modelled.
  • A harmonised, comprehensive and transparent methodology for the characterisation and comparison of such technologies and the barriers to their deployment, which can facilitate public discourse on their role and impacts.
  • Gain better insight into the extended, system-level impacts of these technologies by considering ripple effects (e.g. extended impacts, land benefits foregone, opportunity costs, and rebound effects).
  • Develop abatement cost estimates in function of time profile as well as factors like scale of deployment, key input factors (e.g., land/sea space, energy, reservoirs).
  • Exploration and demonstration of business/ policy/ MRV (Monitoring, reporting and verification) frameworks for CDR uptake at scale, ranging from plant level to incorporation of CDR in international MRV and accounting (for example in the case of bioenergy trade).


Projects under this topic should identify an extended range of nature-based and technical CDR methods, analyse and characterise them in a consistent and transparent assessment framework. In this way, projects should:

  • Deliver realistic estimates of each approach’s potential scale, cost, and effectiveness: on the basis of factors such as technical readiness, key land and other resource needs, geographical and geological constraints, primary energy needs (and associated impacts, including emissions), short- and long-term sequestration potential (including risk of non-permanence), key impacts (environmental, social, health, resource depletion, etc.) and risks.
  • Allow the better parametrisation of integrated assessment models with respect to removals as well a better design of forward-looking policies. Develop abatement cost estimates in function of time profile as well variables like scale of deployment and key input factors.
  • Explore efficient incentive and governance frameworks to facilitate CDR uptake at scale, including social acceptance, ethical and regulatory considerations, as well as identifying major issues and options for establishing MRV and accounting systems associated with CDR in general and specific technologies where applicable.

Analysis under this action should be based on practical experiences (in particular with a range of land-based projects), existing pilot and experimental projects, technical and theoretical analysis and review, including system-level impacts by considering ripple effects through consequential analysis, including land benefits foregone, opportunity costs and rebound effects, key barriers to deployment and governance challenges.

Interactions with CCUS topics under Destination 3 and HORIZON-CL5-2021-D2-01-08: Emerging technologies for a climate neutral Europe under Breakthrough Technologies are encouraged.

Projects investigating the use of CDR technologies for enhanced oil recovery are not eligible.

Where appropriate, interaction with the topics related to climate-ecosystem interaction (HORIZON-CL5-2021-D1-01-08, HORIZON-CL5-2021-D1-01-09, HORIZON-CL5-2022-D1-02-05) as well as marine topics (Cluster 6) is encouraged in order to foster integrative and system approaches including different scientific communities and disciplines, as well as different sectors of the society.

This topic requires the effective contribution of SSH disciplines and the involvement of SSH experts, institutions as well as the inclusion of relevant SSH expertise, in order to produce meaningful and significant effects enhancing the societal impact of the related research activities.
