Objectives
The essential goal of RETAKE is to provide scientifically sound information regarding whether and in what form marine alkalinity enhancement (AE) can be a feasible process in permanently removing significant amounts of CO2 from the atmosphere, in an environmentally sustainable and socially responsible manner.
In particular, this includes:
- quantitative assessments of CO2Â uptake, storage potential, and durability of various AE methods
- an assessment of environmental impacts, risks and co-benefits of AE
- study of regional and global impacts of local AE measures
- assessment and evaluation of economic and social aspects, risks and co-benefits
- evaluation of the legal dimension (now taking place in ASMASYS, RETAKE provides information about scenarios)
- investigation of possible mechanisms to consider CO2Â sequestration through AE in climate policy
- providing information about potential monitoring systems capable of detecting and associating effects of individual AE measures as opposed to natural variations and anthropogenic trends
- analysis of possible synergies and tradeoffs with the SDGs and the German sustainability strategy
- information about further required research in AE measures, which must be conducted before a decision on potential deployment
