UNDA Project on CO2 emissions and ForFITS

Flyer UNDA

The main objective of this project was to enhance international cooperation and planning towards sustainable transport policies.

Its achievement was implemented with capacity building initiatives organized for policy makers and training activities for technical experts, leveraging on the development of a specific modelling tool.

This model, meant to foster sustainable transport policies For Future Inland Transport Systems (and therefore named ForFITS), is capable to assist users in the analysis of measures to reduce CO2 emissions in the inland transport sector.

ForFITS model

ForFITS was developed as a software tool allowing for the evaluation of transport activity, energy use, and CO2 emissions in a range of possible policy contexts.

It is suitable for the analysis of transport systems having a regional, national and/or local dimension, with a primary focus on national systems.
The tool is freely available.


The modelling environment selected for the development of this tool is Vensim. The ForFITS model includes a Vensim Packaged Model file (.vpm), coupled with a Microsof Excel file (.xls).

The latest version of both these files can be downloaded here:

The Vensim Model Reader, a software allowing to run the ForFITS model, is freely downloadable here (selecting the Model Reader option): http://vensim.com/free-download/


Relevant documentation, including a methodological description (updating the draft methodology linked above) and the English version of the user manual are available below.

D - Using ForFITS

The pilot report builds on the application of the model to seven pilot countries: Chile, Ethiopia, France, Hungary, Montenegro, Thailand and Tunisia. The development of each pilot in terms of data gathering, definition of scenarios, model runs and analysis of the results is described in the report. The last chapter contains a set of suggestions for the definition of transport policies having implications for climate change mitigation, leveraging on the results of the pilot runs and a comparative assessment between them. 

After the completion of the first phase of the project at the end of 2013, an international consultant was engaged to evaluate its post-implementation performance.  The evaluation was conducted on the basis of a desk review of all the relevant documents and more specifically an in-depth review of the development of the ForFITS model under the project. The evaluation report summarizes the findings, conclusions and recommendations of the evaluation.
