Emission Growth Factors Models/Tools
EPA has retired the EGAS 5.0 software tool as of July, 2013. EPA provides projected emissions data on the Emissions Modeling Clearinghouse, which is maintained by OAQPS's Emissions Inventory and Analysis Group, for select years modeled as part of EPA rules and Regulatory Impact Assessments. These data can provide a starting point for States to use for other purposes. Please refer to the Emissions Modeling Clearinghouse for the latest information on emissions projections.
