Public procurement can shape production and consumption trends and represents a stimulus for both innovation and diversification in products and services, through a direct increase in demand. In recent years, the interest in demand-side policies has grown and several approaches have emerged, such as Green Public Procurement (GPP), Sustainable Public Procurement (SPP) and Public Procurement of Innovation (PPI), representing strategic goals to be achieved through public procurement. In this context, there is a need to guide and support public organizations in the uptake of GPP, SPP and PPI practices. To respond to the challenges raised by the operationalization of such strategies, this paper proposes a new tool—the SPP Toolbox—for guiding public organizations as they re-think the procurement process, raising their ambitions and broadening their vision, thus changing the organizational approach towards culture, strategies, structures and practices. This toolbox integrates insights from GPP, SPP and PPI objectives and practices, in the context of the emergence of socio-technical transitions. The toolbox coherently links GPP, SPP and PPI, allowing flexibility in terms of goals, yet promoting an increasing complexity of institutionalized practices and skills—from GPP to SPP and then from SPP to PPI, organized in a framework fully integrated into the organizational strategy.

Despite transposing the 2010/31/EU Directive’s requirements creates legal responsibilities at the national level, the nearly Zero energy building (nZEB) principle does not appear to be widely adopted just yet in many nations. Previous studies have shown that the most significant barriers include determining the cost-effective ideal integration of the technologies appropriate for nZEB and the skills constraints faced by the construction industry. In order to meet the challenge of an efficient nZEB implementation, existing certification courses and training programs are still insufficient and inadequate, and hiring experienced specialists for building retrofit and new construction is not common practice. The traditionally conservative real estate industry is nevertheless hesitant to adopt the new building standards and practices, notably in the residential sector, despite a significant movement towards nZEB and extensive energy renovation. In this specific situation, this paper provides a preliminary analysis of the European project nZEB Ready Enhancing Market Readiness for nZEB Implementation, which aims to address the issue of the effective implementation of the nZEB and make use of new possibilities to act at the market level in order to boost the market’s readiness for a successful implementation of the nZEB and to encourage demand for energy-related skills among construction workers and specialists in the countries involved and beyond.
