CollectER EEA-National Emission Reporting Tool

Project information

Index: 0408R1
Priority:2: Environment and risk prevention
Sub Theme:Biodiversity and preservation of natural heritage (including air quality)
Location Start/End date of the practice
Start: 2009

Topic of the practice

CollectER is a database devised by the European Energy Agency, that integrates both greenhouse gases and aerosols. It calculates emissions by multiplying an activity rate (usually production rate) with an emission factor, and the percentage of a certain category (industry, households, etc.) that has a specific emission factor).

Good Practice Information

The CollectER emission inventory software tool is developed by European
Environment Agency (EEA) and its European Topic Centre on Air and Climate Change
(ETC-ACC) since the year 1998. The objectives of the software are to facilitate preparation
of transparent, consistent, complete, comparable and accurate data for emissions reporting
procedures in accordance with the requirements of international conventions, protocols and
EU legislation. The CollectER tool is designed to help national experts on air emissions to collect the
relevant air emission data for delivery to the European Commission and to international
CollectER III is an executable programme, running under the Windows operating system, which manages and compiles an MS Access type of relational database. CollectER III integrates inventory compilation and inventory reporting into one software tool.
The software and this document can be downloaded free of charge from ETC-
ACC’s web site at

Evidence of success

CollectER is the official tool for emission inventory and reporting developed by the European Environment Agency (EEA) and is used by numerous experts and institutes throughout Europe. This tool uses a tailored database platform to help with emission inventory compilation. It allows the input of activity data, selection of different emission factors to give emissions. It also includes point source functionality. One important feature is that CollectER III can be used with ReportER- so that data can be easily output in the different formats needed for AQ or GHG emissions. Historically, the software has been updated whenever there are changes to the required reporting formats/emission factors etc. which has kept it current. So, in summary, it's a very useful tool for national emission inventory compilers- particularly for countries which are starting out with their inventory compilation, and therefore don't already have their own database/data collection system.
