COPERT is a Microsoft Windows software program which is developed as a European tool for the calculation of emissions from the road transport sector. The emissions calculated include regulated (CO, NOx, VOC, PM) and unregulated pollutants (N2O, NH3, SO2, NMVOC speciation …) and energy consumption is also computed. A detailed methodology supports the software application. For more information regarding the methodology, the user should consult the Methodology Report.

COPERT 5 is an updated version of COPERT 4 including both revised methodological elements and a reworked user interface aiming at a compilation of complicated annual national inventories that include multiple countries and years in a single file. This manual discusses all advanced features.

This report is designed in order to help COPERT users to produce in a short time a complete annual national emission data set from road transport. Hence, the manual is divided in several chapters. The different chapters include all information needed to build a complete data set, assuming that the user has no former experience in using COPERT but he is quite familiar with the methodology and the terminology used. Background knowledge in using Microsoft Windows is also expected, although no special skills are required. Major attention has been given to ensure that no erroneous data are inserted. This can certify reasonable results. It cannot guarantee their accuracy though, if input data do not correspond to reality. This is a user responsibility. In order to be compatible with the application, this manual is designed in the same way that the software is developed. The contents in the manual are structured in the same order as the respective forms appear when preparing t
