EDISON INTERNATIONAL

Climate change has, and continues to, impact California. According to the National Centers for Environmental Information, since 1980, California has faced 46 weather-related disasters costing over $1 billion each. In 2024, the Earth experienced its hottest year on record. This spike in temperature is making extreme weather events commonplace, with ripple effects that put people around the world in harm’s way. Severe droughts and windstorms contributed to the devastating wildfires that swept through parts of California in recent years, demonstrating the serious threat that weather extremes caused by climate change pose to California's communities and the environment. See "Management Overview—Southern California Wildfires and Mudslides" in the MD&A and "Business—Southern California Wildfires."

Severe weather events, including drought, increasingly severe windstorms and rising sea-levels, pose risks to SCE's infrastructure and SCE and Edison International are investing in building a more resilient grid to reduce climate- and weather-related vulnerabilities. See "Liquidity and Capital Resources—SCE—Regulatory Proceedings—Wildfire Related Regulatory Proceedings" in the MD&A.

In May 2022, SCE provided its climate adaptation vulnerability assessment ("CAVA") to the CPUC. The CAVA addresses the projected climate impacts of temperature, sea level, precipitation, wildfire, and cascading impacts (such as rain on snow or debris flow) on SCE in the 2030, 2050, and 2070 timeframes. SCE's CAVA will inform planning related to SCE assets, operations, and services, with the goal of maintaining a resilient electric grid in the face of climate change and will inform future investment in the grid. SCE plans to file its next CAVA concurrent with its RAMP application in May 2026.
