To What Extent Are the Green Public Procurement Criteria in National Policies and Action Plans? Commonalities Across European Countries for Environmentally Harmonized Valuations

Green Public Procurement (GPP) is a key tool in European strategies to promote sustainability in public procurement. This study examines the integration of GPP criteria in the National Action Plans (NAPs) of the European Union Member States, with a focus on the construction and urbanizing fields. Through a comparative analysis of policies and regulatory instruments, the main differences in terms of mandatory application between countries in the monitoring and implementation of GPP are highlighted. The comparative analysis of 27 countries reveals significant variation in mandatory execution, regulatory frameworks and monitoring mechanisms. This study proposes an integrated set of indicators that align GPP performance with the Sustainable Development Goals (SDGs) of the 2030 Agenda, providing an holistic framework for the evaluation of policy and strategic planning. The research also explores the role of environmental performance indicators—such as energy efficiency, CO2 emissions reduction and the use of sustainable construction materials—highlighting how these criteria support the ecological transition and contribute to the achievement of the EU climate objectives. The findings offer insights to strengthen the strategic role of GPP in sustainable environmental and territorial planning.
