The 2023 Earth Day theme ("Invest in our planet") urges decision-makers to concretely steer the transition towards a sustainable future for our planet by tackling pressing environmental issues, including climate change, biodiversity loss, and waste reduction. The Destination Earth (DestinE) initiative promoted by the European Commission fits this global effort, funding the development of thematic digital twins that enable scenario simulations, predictions, and bio-monitoring methods, which will enable researchers and other users to better address these challenges and improve predictive performance in biodiversity management. In the wider context of Earth Day 2023, BioDT hosted the webinar "Digital Earth Twins to build resilience to climate change" on 4 April 2023. The team had the chance to introduce the Destination Earth initiative and take a closer look at the expanding ecosystem of projects working on digital twins, addressing key challenges such as climate change and biodiversity protection.
