Climate information plays a fundamental role in achieving a green recovery and climate neutrality. However, this information should be delivered appropriately and used effectively to be integrated into decision-making processes to better manage risks and realise opportunities. As the number and diversity of actors that make up the landscape of climate services keep growing and evolving, new challenges appear. The communities involved in developing and providing climate services are often unaware of each other and lack interdisciplinary and transdisciplinary knowledge. In addition, quality assurance, relevant standards, and other forms of assurance (such as guidelines and good practices) for climate services are lagging behind. Climateurope2 supports the standardisation of climate services to ensure their saliency, credibility, legitimacy and authoritativeness and build two-way trust between supply and demand.
