2021 SERVE 360 REPORT ESG PROGRESS AT MARRIOTT INTERNATIONAL → 27 Climate Resilience Physical climate-related risks, such as severe weather events, are typically managed and updated annually through our enterprisewide approach to business continuity planning, including risk identification, readiness, response, and recovery, relative to operational disruptions. Our corporate risk management department develops and updates policies for insurance coverage for both owners and franchisees, as well as business interruption coverage for our operations in regions prone to events such as tropical storms, flooding, and wildfires. Identification of transition and chronic physical climate-related risks and assessing the degree to which they could affect Marriott’s business is integrated into the governance structure and the materiality assessments that underpin our sustainability and social impact platform, Serve 360. Additionally, Global Engineering is collaborating with Marriott’s Risk Management Team and external collaborators to evaluate and address climate-related risks to the property assets under Marriott’s care and to develop strategies, programs, and trainings to promote climate resilience across the global portfolio of properties. Marriott has launched the Marriott Infrastructure Resilience Adaptability (MIRA) project, which evaluates the growing related risks to the physical assets managed by Marriott and promotes resilient strategies, programs, and training to help mitigate losses associated with these events. During 2020, we launched an education series for associates and engineers of managed hotels called ‘Three Things for Resilience’ and published three training modules focused on cold weather protection of our systems. During 2021, two additional modules related to asset preparation for hurricanes and power outages will be added to the training series.
