The aim of the COMPRO project was to analyse the conditions for a common procurement at European scale of collective and public service transport vehicles.
While stopping right before a full-fledged call for tender, the three-years project intended to generate outcomes of different nature, to the benefit of public authorities and private organisations involved in the field of energy efficient and sustainable transport.

• An initial target was a consolidated background knowledge of the collective transport vehicles market in Europe and expected trends, and the barriers hampering a wider deployment of clean vehicles technologies.
• A second major outcome was the organisation and facilitation of a group of committed cities, to effectively function as the heart of the future purchasing syndicate and to contribute to agglomerating an appealing critical mass for the automotive industry.
• A third ambitious outcome was the convening of the Procurement Management Group, a rare case of participatory consultation opened to the wide range of stakeholders having an influential say in the uptake of clean road transport vehicles.  
• A fourth important outcome, was the thorough analysis and definition of all criteria and key elements needed to be considered in a common procurement scheme at European level. 
• A final outcome was represented by the dissemination effort steered by the project through publications, website, workshops and conferences.
