Project activities are divided into 4 core themes ranging from scientific activities to knowledge exchange and outreach.
The first 3 core themes (CT1, CT2 and CT3) are dedicated to research activities (from component development, process parameterisation, couplings, to interactions with the Integrated Assessment Modelling community); the 4th (CT4) is devoted to the dissemination and exchange of knowledge with stakeholders and the general public.
Interactions between the 4 core themes are facilitated by dedicated cross-cutting actions (XCA1, XCA2 and XCA3) and decision-making boards that link the different activities of the project to ensure their smooth running.
