The California Emissions Estimator Model (CalEEMod), developed in cooperation with air districts throughout the state, is a new statewide land use project emissions model designed as a uniform platform to quantify potential criteria pollutant and greenhouse gas (GHG) emissions associated with construction and operation from a variety of land uses, such as residential and commercial facilities. CalEEMod calculates indirect GHG emissions from energy use, water/wastewater conveyance, solid waste disposal, and vegetation planting and/or removal and the benefits from implementing mitigation measures, including GHG mitigation measures developed and approved by CAPCOA. The model analyzes at the air district, county, air basin, or state level using approved emission factors, established methodologies, and the latest survey data.

The model is available free of charge and can be downloaded and operated from one’s own computer. The latest version of the model (CalEEMod 2011.1.1), a User’s Guide, User’s Tips, Frequently Asked Questions, and future events, such as upcoming training sessions, can be found on the CalEEMod website, www.caleemod.com.
