Terrestrial ecosystems are key to the functioning of the global carbon cycle and play a fundamental role in mitigating climate change. According to the Global Carbon Budget, about 30% of all the carbon dioxide (CO₂) emitted in the atmosphere is removed by vegetation uptake through photosynthesis and accumulation of biomass (so called CO2 sinks on land). Land use change, nutrient limitations, and extreme events (e.g. droughts, fires and heat waves) may limit this potential to sequester carbon. Identifying processes that might destabilise net land carbon uptake is of paramount importance for understanding and managing the global carbon cycle. CONCERTO aims to improve: the current understanding of the terrestrial carbon cycle by adding land processes that are not included yet or not fully developed in Land Surface Models (LSMs); the representation of land change, land use and land management maps to improve the accuracy of carbon fluxes and stocks; the description of impacts on the carbon cycle of extreme events such as droughts, heatwaves and fires, using tools such as state-of-the-art land surface models (LSMs) embedded into Earth system models (EMSs); the integration of LSM improvements in offline global simulations (driven by re-analyses) and in coupled ESMs.

The THRAC3E project is structured around nine interlinked Tasks designed to deliver a comprehensive, regionally disaggregated carbon cycle assessment framework. The scientific approach integrates novel Earth observation (EO) dataset development, process-based and data-driven modelling, benchmarking, and low-latency carbon monitoring across three key regions: Europe, Africa, and Southeast Asia.

UPTAKE aims to facilitate the sustainable upscaling of carbon dioxide removal (CDR) methods by developing a set of robust strategies through technical, theoretical, and practical analysis accompanied by interactive dialogue within a CDR stakeholder forum. As a result, UPTAKE will develop a harmonised, comprehensive, inclusive, integrated, and transparent CDR knowledge inventory to evaluate a wide range of CDR technologies and methods, quantifying their national, European, and global costs, effectiveness, and removal potential as well as risks, constraints, and side-effects at different scales, and their prospects of technological progress. The UPTAKE approach will allow the assessment of geographical, sectoral, socioeconomic, demographic, and temporal trade-offs, co-benefits, and opportunities emerging from portfolios of different CDR methods. The enhanced socio-technical understanding of CDR methods will feed into an ensemble of state-of-the-art integrated assessment models (IAMs), which will help improve the integration of CDR methods given the EU policy objectives set for 2030, 2050, and beyond climate neutrality. UPTAKE will assess CDR governance and policy frameworks considering social acceptance, accountability, monitoring, and regulations for sustainable CDR rollout at scale. As a result, UPTAKE will generate an open and interactive CDR roadmap explorer to investigate strategies that are resilient to risks of failure and disruption, and minimise adverse impacts on society, economy, and the environment, aiming for a just, inclusive, and sustainable transition.
