The ForestNavigator project assesses the climate mitigation potential of forests and forest-based sectors by modelling robust policy pathways, aligned with medium (2030) and long-term (2050) climate goals, and supporting EU and national decision makers. ForestNavigator applies integrated approaches combining observational data, policy expertise, and a range of advanced modelling tools to develop a Policy Modelling Toolbox, capable of addressing climate change impacts on coupled ecological and socioeconomic systems. The Toolbox relies on a near-real time monitoring of forests, carbon and biodiversity, and provides policy makers with efficient decision-making tools for climate action. With a primarily European scope, ForestNavigator zooms into carefully selected EU Member States to enhance the consistency of the EU and national pathways, and zooms out towards the global scale, for extra-EU future drivers and potential leakage effects.
