Ever wonder why countries can never agree on issues related to climate change and the environment? Young Scientists Summer Program (YSSP) participant Felix Schenuit dives into the politics and challenges surrounding carbon dioxide removal in international climate negotiations.
The Paris Agreement has been lauded as a landmark effort to address climate change and has been signed by nearly every country in the world. The agreement sets out ambitious goals such as reaching temperature targets, setting net-zero carbon targets, and providing financial, technical, and capacity building support to those countries that need it.
One topic that has been receiving increasing attention since the adoption of the agreement is carbon dioxide removal, or CDR – which comprises man made processes involving the direct removal of carbon dioxide from the atmosphere and sequestering it somewhere else, usually underground or under the sea floor. Since it was first proposed, CDR has been discussed on many platforms including critical comments, journals, and studies. 2021 IIASA YSSP participant Felix Schenuit studies how the debate, which has been largely ignored by policymakers until the Paris Agreement, is evolving, and how CDR is being taken up in climate policymaking.

Felix Schenuit comes from a background of political science and public policy. It was during his employment at the German Institute for International and Security Affairs (SWP) that he became fascinated by CDR and the political debates surrounding the impacts it can have on the fight against climate change. This is when he decided to combine his newfound interest with his background and experiences in international relations and public policy to pursue a PhD at the University of Hamburg comparing CDR policymaking in different countries and the role scientific knowledge has on its implementation.
Building on a previous study comparing CDR governance among nine Organisation for Economic Co-operation and Development (OECD) cases, Schenuit is now focusing on the role of scientific knowledge surrounding CDR in Brazil, China, India, and Russia. These countries account for a significant portion of the world’s greenhouse gas emissions due to their rapid industrialization and expanding economies. China and India are especially significant due to their great influence in ongoing international climate negotiations regarding the Paris Agreement.
Schenuit uses integrated assessment models to gather information and data about the role of CDR in different countries in decarbonization pathways.
“These models help us to understand what amount of CDR we are likely to need to achieve Paris Agreement targets. Case studies on specific countries are an important second step to explore facts on the ground about different policy initiatives, emerging CDR facilities, and efforts in each region. We reach out to country experts and build interdisciplinary bridges to investigate how CDR is addressed politically, what amounts are available and politically feasible, as well as relevant knowledge gaps,” he explains.
One of the biggest challenges remaining for CDR is limited knowledge about different CDR methods, both in science and policy circles. There are many ways one can remove carbon dioxide from the atmosphere, ranging from afforestation, to soil carbon sequestration, ocean fertilization, direct CO2 capture from the air, and the use of biochar, among others.

“When it comes to methods, many policymakers are unaware of the portfolio of available methods. Each method has different tradeoffs, both environmentally and politically. For example, in Germany, carbon capture and storage (CCS) is very contested and most policymakers are hesitant to even address CDR. Thus, in Germany one may need a different set of methods than in the UK, for example, where CCS-based CDR methods are pursued proactively,” Schenuit says.
Many predict that the role of international politics in CDR governance under the Paris Agreement is going to be difficult and tricky to navigate. Schenuit argues that it is still a bit too early in the debate for predictions as policymakers have only recently been directly addressing CDR. He does however agree that there is already strong evidence of politics at play and alliances are forming.
The study on Brazil, China, India, and Russia will yield fascinating results, as it will give us an idea about future disputes and questions regarding the carbon in our atmosphere. Questions like where we will be removing carbon and who is going to pay for it. One thing is for certain, however. Time is running out to meet the targets of the Paris Agreement, and international cooperation is desperately needed.
