The main purpose of the Wildfire Smoke Emergency Declaration Act of 2026 is to give the President the authority to declare a smoke emergency when air quality is significantly affected by smoke from wildfires. This declaration aims to facilitate a coordinated federal response to protect public health and safety in affected areas. Key provisions of the Act include the ability for governors of states to request a smoke emergency declaration from the President. Once declared, the federal government can provide assistance to states and local communities.
