The increase in the frequency and intensity of natural events related to climate change implies that in the medium/long term industrial assets might be operating under more severe conditions, with a possible increase in operating risks (Physical Risk). This paper describes the approach developed by Eni to assess the resilience of its assets to climate change, by verifying the consistency of the design bases with the new expected medium/long-term conditions. Based on quantitative prospective data, Eni has developed the "Delta-Climate" methodology that analyses the quantitative variations between current and future conditions and verifies the adequacy of the design criteria, considering that the historical conditions have been properly accounted for in the design, construction and operating phases. The model considers specific tolerance thresholds for each natural event and for each type of asset, both in absolute and percentage terms, to consider best design and operating practices. Assets potentially operating in the future under climate conditions outside of the reference thresholds are highlighted, to be further investigated within the Asset Integrity processes. The "Delta-Climate" methodology allows the integrated energy company Eni to assess the Physical Risk of its entire portfolio of industrial assets promptly highlighting assets with potential critical climate issues, also quickly allowing to re-analyze all the assets when climate forecasting models are updated to reflect scientific advancements. The application of the "Delta-Climate" methodology relies on a Climate Intelligence Data Provider capable to guarantee worldwide coverage (onshore, offshore); metrics for acute and chronic climate-related natural events; medium/long-term time horizons; different socio-economic emission scenarios and statistical return periods; and the possibility to develop custom metrics. This method is an improvement of the top-down screening approach, since it fosters the full involvement of both technical engineering functions and Asset Managers, at Headquarter and Business Units levels. It guarantees that up-to-date knowledge about the plants is used, and supports the Asset Managers, who bear the responsibility to address potential criticalities emerged from the analysis. The winning factors of this approach are: speed and pervasiveness of the analyses; strengthened cooperation between technical departments, Asset Managers and the Risk Management departments; direct input into the Asset Integrity process, with support to engineering for the definition of the design bases and to Asset Managers for the identification of mitigation actions and adaptation plans; strengthening of the mandatory CSRD disclosure; appreciation by financial institutions to support their sustainability investment criteria.
