Circular Carbon Flows and their monitoring

Client Umwelt Bundesamt

Duration April 2024 – November 2025


With the goals of the Paris Agreement and the resulting greenhouse gas neutrality targets for Germany (2045) and the EU (2050), as well as the possible subsequent targets for negative emissions, carbon will play a different role in our economic system in the future than it has to date. On the one hand, climate policy considerations will focus on avoiding greenhouse gas emissions, above all carbon dioxide, as quickly and comprehensively as possible. In addition to the emitters, possible storage and sinks will also become more relevant in future. On the other hand, carbon currently serves as an important input in some areas. In the future, a circular carbon economy will become important. The recording and accounting of emissions has not yet been geared towards such a circular carbon economy.

Goals and Results

The project includes the preparation of the climate protection and projection report in 2024. The report describes the development of GHG emissions in the various sectors and the implementation status of climate protection measures in the reporting period, as well as projections of GHG emissions and their impact on the achievement of the sector targets by 2030 and the climate protection targets for Baden-Württemberg for 2030 and 2040. In addition, a sector-specific cause analysis for potential target deviations and the respective responsible decision-making level as well as proposals for measures to re-achieve the target path in the respective sector and proposals for the further development of climate protection measures must be made. The impact contributions and interactions of climate protection measures of the federal government and the European Union (EU) must also be taken into account. In addition, important aspects of a cause-related approach must be included.

Tasks of IREES

  • Analysis of possible carbon pathways in a future carbon economy Graphical processing of carbon flows

  • Analysis of the previous recording of CCU, CCUS, CCS processes in the Federal Climate Change Act

  • Collaboration in the development of a consistent inventory and accounting framework

  • Collaboration on recommendations for the further development of the mapping of the circular carbon economy in the architecture for sustainable greenhouse gas neutrality and its monitoring
