Synthesis Table on soil carbon data generators/repositories of European capabilities

Soil Organic Carbon (SOC) is vital for climate mitigation, agriculture, and ecosystem health. As the EU advances the Carbon Removal and Carbon Farming Certification (CRCF) regulation, reliable SOC assessment and monitoring is essential. This synthesis assesses ten major European data systems—including monitoring networks, farm platforms, and research infrastructures—highlighting their strengths and gaps. While some systems offer high-quality, open data, many face issues with accessibility, interoperability, and standardization. Integration challenges and uneven coverage hinder effective Monitoring, Reporting and Verification (MRV) and policy support. The report recommends aligning data systems with CRCF regulation standards, supporting Application Programming Interface (API) development, and embedding scientific infrastructures into certification frameworks to improve data credibility, reduce costs, and support climate-smart land use.
