Decoding the green DNA: organisational drivers for GPP adherence in SMEs

This study investigates the organisational characteristics driving SMEs’ motivation to adhere to Green Public Procurement (GPP) practices. Using the Resource-Based View as a theoretical lens, this study examines how environmental organisational culture, green training programmes, and managerial vision for sustainability influence GPP motivation in SMEs. We relied on a sample of 206 small and medium enterprises (SMEs) from Andalusia and conducted a moderated mediation regression analysis using macro-PROCESS. Green training programmes (GTP) acts as a mediator, while Managerial Vision for Sustainability (MVS) acts as a moderator in the relationship between Environmental Organisational Culture (EOC) and GPP adherence. By examining the influence of these organisational factors on motivation towards GPP, our findings reveal that a strong EOC and well‑developed GTP are associated with higher motivation to adhere to GPP. These results provide valuable insights into how SMEs can leverage internal resources to enhance their GPP motivation, support reduced environmental impacts, and embed sustainable practices in corporate strategies. Practices. This research contributes to a deeper understanding of the organisational drivers that motivate SMEs to adhere to GPP programmes in the case of SMEs, thus advancing sustainable development in SMEs.
