About this manual

The purpose of all emission estimation technique (EET) manuals in this series is to assist Australian manufacturing, industrial and service facilities to report emissions of listed substances to the National Pollutant Inventory (NPI). This manual describes the procedures and recommended approaches for estimating emissions from facilities engaged in maritime operations.

Activities covered in this manual apply to facilities primarily engaged in the operation of ports (ie. the loading and unloading of freight), ballasting, transit, and maintenance and general upkeep of ocean going and inland water vessels. This manual does not cover facilities engaged in shipbuilding, refit, overhauls, and dry-docking activities.
