Guidebook on Preparing Airport Greenhouse Gas Emissions Inventories provides a framework for identifying and quantifying specific components of airport contributions to greenhouse gas emissions (GHG). This guidebook can be used by airport operators and others to prepare an airport-specific inventory of greenhouse gas emissions. It identifies calculation methods that can be applied consistently, improving comparability among airports and enhancing understanding of relative contributions of greenhouse gases to local environments. The inventory methods presented focus on the six primary greenhouse gases: carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons, and perfluorocarbons. As part of the methodology, the guidebook provides instructions on how to calculate emissions from specific sources and how to create carbon dioxide (CO2) equivalencies. |
