Digital twin technology holds significant promise in developing solutions to mitigate the damage caused by climate change and facilitating the transition to greener alternatives. The European Commission is leveraging this technology to create a digital twin of the ocean (DTO), a highly accurate digital model aimed at facilitating studies, improving decision-making, and providing essential ocean data. The ERC-funded TwinPolitics project seeks to address concerns surrounding the socio-technical aspects of DTOs and their use in national and international contexts. The project aims to investigate current challenges related to development, access, security, legal considerations, and necessary regulations. Additionally, it will develop a methodological approach to address these challenges and ensure the effective use of DTOs.
