C1. Integrating the CRCF into International MRV Systems and the Global Climate Action Agenda , with MARVIC partners Eric Ceschia and Suzanne Reynders.

This session examined how the CRCF can be aligned with international MRV systems and global climate reporting, exploring how CRCF data and methodologies could support national climate targets, NDCs, and broader public objectives such as soil health and farm income. Among others, the session featured how the SOC monitoring methodologies for the CRCF could be aligned with other contexts of MRV (CAP, NDCs) and why it would be a benefit for those different contexts of MRV to do so.

E4. Data and Approaches for Consistent Quantification of Emissions and Removals in Baseline and Carbon Farming Activities , with MARVIC partners Liisa Kulmala and Layla Höckerstedt.

This session focused on methodological and data challenges in quantifying emissions and removals under the CRCF Regulation with particular attention to baseline definition and consistency, and their implications for calculating net carbon benefits. The session brought together scientists, public authorities and private sector actors to identify best practices for robust and scalable MRV, exploring case studies in agricultural and forest land.

E5. Cost-effectiveness: harnessing state-of-the-art technology to scale viable Carbon Farming MRV , with MARVIC partners Ahmad Al Bitar and Andrea Ferrarini.

This session explored how advanced technologies can address the cost–accuracy bottleneck in carbon farming under the CRCF, supporting robust, scalable, and cost-effective MRV systems. Among others, the session featured the use of earth observation and crop-soil modelling to quantify soil organic carbon changes at the specific plot level in France and smart sampling strategies using optimisation algorithms validated over 2,000 hectares in Italy.

E6. Data Sharing in Action: From Uncertainty to Trust in Carbon Farming MRV , with MARVIC partners Hui Xu and Sofia Biffi.

This workshop brought together actors across the carbon farming value chain to improve data collection, sharing, and uncertainty management for robust and cost effective MRV consistent with the CRCF. The session began with short success stories of data sharing and insights into uncertainty assessment, followed by interactive discussions.

E7. Soil Carbon Modelling for Scalable and Reliable MRV: Insights from MRV4SOC and MARVIC Projects , with MARVIC partners Greet Ruysschaert, Liisa Kulmala, Marta Bertola and Hui Xu.

In this session, the speakers presented results from some case studies of the MARVIC and MRV4SOC projects, focusing on exploring challenges and assessing solutions in modelling performance and uncertainties. The session also provided scientific insights into how modelling approaches can support transparent, cost-effective, and robust MRV systems for European carbon farming.

D8. Scaling Carbon Farming with Stakeholders: Trust, Certification Frameworks, and Local Initiatives , with MARVIC partners Silvia Coderoni and Niklas Witt.

This session aimed to bridge gaps between scientific design, policy frameworks, and market implementation, sharing stakeholder perspectives on MRV complexity, certification credibility, governance challenges, and limited farmer trust. The speakers presented different case studies such as holistic certification frameworks integrating soil health, biodiversity and water quality, local carbon credit schemes, sector-specific certification approaches, and public–private action platforms.

E11. Data Standardisation and Harmonisation towards Credible MRV systems , with MARVIC partners Fenny van Egmond, Hui Xu and Sofia Biffi.

This session presented results from projects MARVIC, MRV4SOC, Credible, CAFAMORE and SoilWise regarding data standardisation and harmonisation for Tier 3 model-based MRV systems, which require large, diverse datasets for calibration, running, and validation. In this session, MARVIC partners showcased project results related to demo and benchmark sites, farm data assessment for MRV, availability, accessibility and interoperability of sources, and the need and operationalisation of standardised vocabularies for MRV.

A9. Opportunities for Cooperation on Agroforestry Carbon Farming Between European Research Projects, and Extension to Projects Operating in Africa , with MARVIC partner Greet Ruysschaert.

This session featured representatives from several projects to facilitate knowledge exchange among European agroforestry research projects addressing MRV challenges for carbon farming certification, while also exploring opportunities for collaboration with EU–Africa research projects. In this session, MARVIC presented the project advances in this topic.
