Research Cluster Climate Policy and Politics

Projects

The aim of the ASMASYS II project is to develop and assess marine CO₂ removal (mCDR) scenarios. Particular attention will be paid to assessing the future political feasibility of such scenarios.
The project analyses current developments and challenges in international climate cooperation as well as their implications, options and priorities for German and EU climate diplomacy
Removing CO2 from the atmosphere (Carbon Dioxide Removal, CDR) is essential to achieving greenhouse gas neutrality in Germany, Europe and globally. A wide range of terrestrial, geological, material-based and marine CDR approaches have been proposed, and the scientific understanding of each method varies greatly.
UPTAKE aims to facilitate the sustainable upscaling of carbon dioxide removal (CDR) methods by developing a set of robust strategies through technical, theoretical, and practical analysis accompanied by interactive dialogue within a CDR stakeholder forum.
The research project accompanies the German government’s “climate foreign policy” strategy from its inception to its implementation.
The »State of Carbon Dioxide Removal« report is a global, independent scientific assessment of carbon dioxide removal research, development, demonstration, deployment, perceptions, scenarios and policymaking.

Marine CO₂-Removal: Scenarios and Governance (ASMASYS II)

The aim of the ASMASYS II project is to develop and assess marine CO₂ removal (mCDR) scenarios. Particular attention will be paid to assessing the future political feasibility of such scenarios.
German climate diplomacy in the context of the European Green Deal

The project analyses current developments and challenges in international climate cooperation as well as their implications, options and priorities for German and EU climate diplomacy
Governance of Carbon Dioxide Removal (CDRSynTra)

Removing CO2 from the atmosphere (Carbon Dioxide Removal, CDR) is essential to achieving greenhouse gas neutrality in Germany, Europe and globally. A wide range of terrestrial, geological, material-based and marine CDR approaches have been proposed, and the scientific understanding of each method varies greatly.
Upscaling of Carbon Dioxide Removal (UPTAKE)

UPTAKE aims to facilitate the sustainable upscaling of carbon dioxide removal (CDR) methods by developing a set of robust strategies through technical, theoretical, and practical analysis accompanied by interactive dialogue within a CDR stakeholder forum.
International Climate Policy and Multilevel Governance (Ariadne)

The research project accompanies the German government’s “climate foreign policy” strategy from its inception to its implementation.
State of CDR Report

The »State of Carbon Dioxide Removal« report is a global, independent scientific assessment of carbon dioxide removal research, development, demonstration, deployment, perceptions, scenarios and policymaking.
