Air Quality can provide a comprehensive Air Emissions Inventory following recognized International Protocols and Guidelines. The AEI includes the following:

• Identification of all emission sources by facility.
• Emission loads obtained from measured pollutant emissions for all point sources.
• Estimated emission loads obtained from calculations or engineering design information for all other point sources.
• Fugitive emissions estimates based on calculations utilizing procedures, methodologies and appropriate air quality emission factors as provided in USEPA AP-42: Protocol for Equipment Leak Estimates.
• An estimate of emissions from storage tanks and transfer operations.
• Estimated inventory of six greenhouse gases–carbon dioxide, methane, nitrous oxide, hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF6) from all point sources as per Kyoto Protocol.
