limate information is vital for achieving a green recovery, climate neutrality, and resilience in Europe. Yet, this information must be delivered in ways that decision-makers can trust, understand, and use. Climate services (the tailored provision of climate information for decision-making) play a key role in this process. The demand for climate services has grown rapidly, but so too have challenges. The field is diverse and fragmented, with many actors, inconsistent standards, and limited quality assurance. This makes it difficult for users to compare services or trust their reliability. Building on the legacy of the earlier EU project Climateurope, Climateurope2 works to support the standardisation of climate services so they are credible, relevant, and equitable. The project develops a framework for equitable standardisation, identifying criteria for quality assurance and certification, and defining when technical, procedural, or performance standards are most appropriate. It also contributes to the work of CEN/CENELEC Technical Committee 467, which is developing the first European climate services standard. At the same time, Climateurope2 strengthens Europe’s community of practice, connecting scientists, policymakers, businesses, and civil society through events such as Festivals, online Webstivals, art–science collaborations, and Travelling Climate Action Roadshows. The interactive Climateurope2 Platform supports this network by providing resources, discussion spaces, and a shared glossary. Social sciences and humanities play a central role, ensuring that standardisation considers ethical, social, and governance aspects and that services are equitable and useful in real-world decisions. By the project’s end, Climateurope2 will deliver recommendations and good practices to guide standardisation and quality assurance, helping Europe better prepare for climate challenges.
