European Union Green Public Procurement (GPP) criteria for road marking materials (comprising paints, plastic masses, and tapes) have been recently published. Among the criteria, the key is limitation in the contents of Volatile Organic Compounds (VOC); as a novelty in Europe, several solvents would be exempt from the VOC content calculations. Other parameters include exclusion of hazardous materials, heavy metals, and ingredients that would cause significant hazard warnings. In addition, contents of titanium dioxide and the quantity of recycled materials in glass beads are specified and durability of road marking systems is included. In this review, the key points of the GPP are assessed and uncertainties are pinpointed and discussed. Particular attention is given to solvents, which belong to inalienable ingredients in road marking paints. Amongst demonstrated weaknesses of the GPP, the use of nominal VOC contents instead of Ozone Formation Potential and downplaying the impact of service life on overall emissions and materials consumption appear to be the most important. Results from field testing of road marking paints are provided to exemplify this weakness.
