Green public procurement (GPP) has been extensively adopted as a public administration tool for achieving sustainability outcomes. However, there is a marked lack of understanding regarding the determinants of GPP adoption beyond, that is, the characteristics of the contracting authority. Indeed, most studies have focused their attention on these micro determinants, with little being known about the macro and meso factors involved. In this paper, we contribute to the literature by analyzing macro and meso adoption factors. To do so, we explore GPP in the award criteria for twentyfive European countries as recorded in Tenders Electronic Daily database for the period 2006–2017. Our results show significant cross-country differences in GPP uptake and we identify factors beyond those of the contracting unit itself that condition GPP adoption. Specifically, more developed countries and a larger government size impact positively on GPP. GPP adoption has evolved favorably over time, and regional and local administrations show a clearer preference for GPP than is shown by national governments or EU authorities. We find that better governance is linked to GPP adoption and that larger contracts are more likely to include GPP. Our results confirm that join procurement between contracting authorities more probability to adopt GPP. Our results are useful for defining a more comprehensive decision-making framework for GPP. •Macro and meso determinants of GPP have largely been omitted from previous studies.•We explore GPP in the award criteria in the European TED database.•Size of government and economic development are positively associated with GPP adoption.•Good governance and local and regional government also have a positive impact.•Positive effects on GPP adoption over time and across-country exist as do differences by sector.
