RenaissanceRe 2025 Sustainability Report A Message From Our CEO About This Report Sustainability Strategy Our Portfolio Our Partnerships Our People Our Operations Our Communities Our Governance Metrics and Performance Looking Ahead Appendix 46 Metrics and Performance We use a range of metrics to monitor our progress and assess the effectiveness of our sustainability approach. These metrics support decision-making across our underwriting, investment and operational activities, and provide transparency to our stakeholders. Our approach reflects the same principles that guide our core business: focus on what is important, measurable and relevant to long-term resilience. Over time, we expect to further develop metrics in areas where data quality and methodologies support meaningful measurement. Environmental Metrics We measure and monitor our GHG emissions across Scope 1, Scope 2 and relevant Scope 3 categories, in line with the GHG Protocol. These metrics support our understanding of our operational footprint and inform actions to improve efficiency over time. Key indicators include: • Total GHG emissions (location-based and market-based) • Emissions intensity per employee and per unit of revenue • Energy consumption across offices and data centers Investment Metrics We assess sustainability-related characteristics within our investment portfolio as part of our broader approach to risk and return. Key indicators include: • Carbon intensity of corporate credit and equity portfolios • ESG data coverage across investments • Allocation to lower-carbon and sustainability-aligned assets These metrics support our understanding of climate-related risks and opportunities within the portfolio and inform ongoing portfolio management decisions. People Metrics We track workforce metrics to understand how we attract, develop and retain talent and to support an inclusive and high- performing culture. Key indicators include: • Workforce composition by gender and leadership level • Employee headcount and geographic distribution • Participation in training and development programs Community Metrics We measure the reach and effectiveness of our community initiatives, with a focus on education, opportunity and resilience. Key indicators include: • Total community investment • Employee volunteering participation • Employee-directed giving • Number of beneficiaries supported through education and employment programs These metrics help us assess the impact of our programs and guide future investment. Governance and Risk Metrics We monitor governance and risk-related indicators to support effective oversight and accountability. Key indicators include: • Participation in compliance and ethics training • Integration of ESG considerations into decision-making processes • Climate-related risk considerations within ERM and underwriting Ongoing Development We continue to refine our metrics and disclosures as methodologies evolve and data availability improves. As with all forward-looking assessments, there are inherent uncertainties and data limitations, and we will enhance our approach over time as more robust and comparable information becomes available.
