The Co-benefits Risk Assessment (COBRA) Screening Model inexpensively and quickly estimates the air quality, human health, and associated economic impacts of various state-and county-level emission reduction scenarios. This tool serves as a preliminary screening tool to identify those scenarios that might benefit from further evaluation with more sophisticated air quality modeling approaches.
