This paper&lt;br&gt; specifically addresses the topic of environment-friendly and sustainable procurement of road works (Green&lt;br&gt; Public Procurement). The Belgian Road Research Centre has formed a national working group with members&lt;br&gt; from road administrations, road contractors, and sustainability experts.&lt;br&gt; The main objectives of this working group are to help road authorities (at the national and regional levels) in the&lt;br&gt; process of including sustainability indicators in their road tenders, with a view to achieving Green Public&lt;br&gt; Procurement in their road projects, and to keep abreast of new developments: European guidelines, best practices&lt;br&gt; in the sector, progress in other sectors such as the building industry, and certification in other sectors and in road&lt;br&gt; construction.&lt;br&gt; The aim is to define the most important sustainability (environmental-social-financial) indicators in the life cycle&lt;br&gt; of a road pavement, and use the evaluation of these to come to an overall assessment of the road’s sustainability&lt;br&gt; for use as a criterion in tendering. Pragmatic choices are made from the basket of sustainability indicators to&lt;br&gt; keep the methodology easy and simple yet objective, without aspiring to a full life cycle analysis.&lt;br&gt; A pilot project has been set up with global warming potential, the depletion of materials, noise, responsible&lt;br&gt; sourcing, road availability and annoyance to people, and direct construction costs as environmental, social and&lt;br&gt; financial indicators. Each of these is split up into sub-indicators (such as road transport, recycled contents, tyreroad&lt;br&gt; noise, or rolling resistance) that are all assessed by an easy procedure for both the contractor and the road&lt;br&gt; administration, respectively, thereby delivering and checking the sustainability information in the tender.&lt;br&gt; The evaluation leads to a single value, i.e., a weighted sustainability score. This score affects the actual tender&lt;br&gt; price in such way that direct costs as well as the sustainability score both determine which contractor wins the&lt;br&gt; bid.&lt;br&gt; The paper describes the implementation of the methodology in the pilot project.<br /> <br /> <br /> == Original document ==<br /> <br /> The different versions of the original document can be found in:<br /> <br /> * [https://zenodo.org/record/1446070 https://zenodo.org/record/1446070] under the license http://creativecommons.org/licenses/by-nc-nd/4.0/legalcode<br /> <br /> * [http://dx.doi.org/10.5281/zenodo.1446069 http://dx.doi.org/10.5281/zenodo.1446069],<br /> : [https://zenodo.org/record/1446070 https://zenodo.org/record/1446070] under the license http://creativecommons.org/licenses/by-nc-nd/4.0/legalcode<br /> <br /> * [https://zenodo.org/record/1446070 https://zenodo.org/record/1446070],<br /> : [http://dx.doi.org/10.5281/zenodo.1446070 http://dx.doi.org/10.5281/zenodo.1446070] under the license http://creativecommons.org/licenses/by-nc-nd/4.0/legalcode<br /> <br /> <br /> <br /> DOIS: 10.5281/zenodo.1446070 10.5281/zenodo.1446069</div>
