Cool initiatives: Rethinking heat response in New York City

Abstract

As extreme heat events in New York City increase in frequency and intensity, existing response strategies must evolve to address growing risks to public health and infrastructure. This paper examines updates to the City’s (hereafter, ‘the City’ refers to the municipal government) heat emergency approach, based on initiatives piloted during the 2024 and 2025 summer seasons. The study outlines key changes to public messaging, operational planning, and community engagement. Messaging was revised to emphasise the health risks of extreme heat and promote earlier individual preparedness. The City expanded its approach beyond traditional Cooling Centers, introducing a broader concept of ‘Cool Options’ that includes a wider range of indoor and outdoor locations accessible to residents. New mapping tools were developed to provide continuous public access to information on cooling options across the city. The paper also describes targeted strategies to reach vulnerable populations, including partnerships with community organisations and the distribution of heat safety resources. Additional initiatives focused on improving accessibility, increasing awareness, and supporting at-risk groups during prolonged heat events. The findings demonstrate the importance of flexible, community-focused approaches to managing extreme heat. Continued evaluation and expansion of these strategies are expected to strengthen resilience and reduce heat-related health impacts in future increasingly severe conditions.
