The Ventura County Air Pollution Control Board awards Clean Air Fund grants for community projects that reduce emissions that contribute to ozone and particle pollution. Ventura County exceeds current state and federal standards for ozone and the state standard for PM10, which is particulate matter with a diameter up to 10 micrometers. Clean Air Fund grants also support projects that address climate change, for instance by reducing emissions of greenhouse gases or mitigating the impact of carbon released into the atmosphere.
