D2.1 Catalogues of collected empirical and generated original data on climate related risks, damage, and losses

This deliverable presents the identification, organisation and documentation of climate change impact data relevant for the objectives of the PIISA project. The work carried out under Task 2.1 aims to strengthen the data foundations required to support climate risk assessment and the development of climate services for the insurance sector. Insurance-based climate risk management requires integration of several types of information, including hazard observations, vulnerability data and, critically, damage or impact data. However, the availability and accessibility of climate impact datasets remain uneven across Europe, and information on economic losses or damage records is often fragmented, inconsistent or difficult to access. In this context, D2.1 provides a structured inventory of climate change impact datasets and related data portals at the European level, with particular attention to datasets that can support insurance decision-making and climate risk analysis. While the catalogue does not aim to be exhaustive, it highlights key datasets and platforms that are widely used or particularly relevant for the sectors and hazards addressed in PIISA. A central component of the deliverable is the development of an online catalogue that organises this information in a structured and searchable format, allowing users to explore datasets, understand their characteristics and identify potential sources of impact data for climate risk analysis. In addition to the inventory of existing datasets, the deliverable documents the integration of selected climate indices developed within PIISA into the Joint Research Centre (JRC) Risk Data Hub. These indices represent climate hazard indicators and impact precursor datasets that can support risk assessment and the development of climate-informed insurance solutions. While D2.1 documents their integration into the broader data landscape, the detailed technical description of these indices and their role within pilot climate services is provided in Deliverable D2.3. Overall, D2.1 contributes to improving transparency and accessibility of climate risk data, supporting the development of innovative climate services and insurance solutions aimed at strengthening climate resilience across sectors.
