The EU-funded 4C project fills the knowledge gap on CO₂ emissions by reducing uncertainties in the global carbon cycle processes and feedbacks

 4C provides key knowledge on climate-carbon interactions and feedbacks to support IPCC assessments and policymaking

4C ensures that the latest knowledge on the carbon cycle is shared and updated on the ScienceBrief platform

4C reduces uncertainties in climate projections over the 21st century and supports the Paris Agreement by providing the best available science
