The Whale CHARTS Act of 2026 aims to enhance the protection and management of migratory whales and other large cetaceans in U.S. waters. By establishing a comprehensive program for mapping, surveying, monitoring, and mitigating risks to these marine animals, the legislation addresses threats from human activities, particularly vessel collisions. Key provisions include the creation of a detailed mapping and monitoring program that utilizes advanced data collection methods and technologies to track the distribution and movements of migratory whales.
