There’s no doubt that public procurement must and will become more sustainable. The changes present great challenges to purchasing agents because, despite sustainability’s relevance, the issue has thus far been neglected in public procurement. Consequently, the agents lack clarification on one hand and concrete assistance with practical implementation on the other. In order to change that, the Professional Division of the Mainz-based cleaning products manufacturer Werner & Mertz, is working with the Forschungsgruppe für Recht und Management öffentlicher Beschaffung (FoRMöB) at the University of the German Armed Forces in Munich. Together they have founded the VERGABE INSIDER, an online trade journal for everyone who deals with green public procurement. Another important partner in the magazine is NABU (Nature and Biodiversity Conservation Union).
