Abstract
Atmospheric emission inventories are useful tools to support informed decision making in air quality management. In the
framework of Apulia Region emission inventory, a tool for the industrial atmospheric emission management called Territorial
Emissions Cadastre (CET) was developed. CET is a Web-based system able to store all data related to the industrial plants and to
perform spatial queries; its components are used for synchronizing, exporting and querying the underlined database. CET also
enables access to information that is useful to support air quality monitoring experts in their decision-making process. An
innovative feature of CET is CETGE. It allows the users to visualize the industrial plants and the associated emissions in Google
EarthŽ which provides an effective tool to display the most relevant industrial emission sources on a Regional area view.
CETGE can be used by the stakeholders to evaluate and present alternative solutions for areas characterized by high impact
emission sources.
