Every year public authorities in the EU spend around 14% of GDP on Public Procurement (PP), which amounts to more than EUR 1.9 trillion. To this end, ‘Greening’ public procurements is among the key factors that stimulate the transition to a resource efficiency and green growth, as it is strongly highlighted in the recently launched EU Green Deal.Especially for construction works, public sector is a key source of demand. Considering that the construction sector is one of the most resource-intensive sectors, Green Public Procurement (GPP) in the sector is a key driver for works with limited environmental impact, as well as a major contributor to reaching the EU environmental, sustainability and energy efficiency targets.Nevertheless, EU countries face many obstacles in implementing GPP policies, ranging from lack of information, training, and knowledge for establishing criteria and standards eligible with GPP, along with inadequate capacity building of the PP workforce and limited knowledge transfer between practitioners and the educational sector.In this context, the GUPP project anticipates to tackle the aforementioned challenges and needs through developing capacity building and increasing learning opportunities of the public procurement related staff and public and procurement authorities in implementing GPP that address green criteria and standards in construction works.With this respect, the project envisions to have overall impact on the construction sector, by responding to current, emerging and growing needs of the sector for accelerating transition to a resource efficient and circular economy, towards EU's energy and environmental goals. In parallel, with view to the training system, the expected impact is to enhance the education’s sector capacity building towards meeting the abovementioned challenges by integrating innovative learning tools and resources and facilitating the supply of high quality learning opportunities for adults, through making available flexible learning offers tailored to their learning needs. Overall, the project foresees to:-Enable behavioural changes of key stakeholders involved in a PP process towards a sustainable, greener and circular economy.-Create new opportunities for public authorities to stimulate resource efficiency and green growth.-Facilitate knowledge transfer between key stakeholders involved in PP processes, as well between practitioners and the educational sector and raise awareness about the lifecycle environmental impacts of projects.-Strengthen synergies and empower transnational social dialogue between all relevant stakeholders.The aforementioned results will be achieved through the implementation of complementary activities and innovative outputs, as follows:-The development of a Green Handbook: An instrument on GPP Regulatory Framework and Practice on Construction Works, that will provide a general understanding of the GPP process and challenges faced upon its implementation on construction works.-The development of the GUPP capacity building program that will provide participants (public procurement staff, professionals of construction works), with up-to-date knowledge and advanced aspects of GPP in construction works, facilitating deeper knowledge and familiarity with GPP.-The development of the GUPP Web Platform, an online hub for GPP that will serve as an innovative e-training and e-learning tool and will bring together all the latest news, events, and resources on GPP and enhance retention and learners engagement, as well enable social dialogue and knowledge transfer on the subject matter.-Engagement with GPP in construction works, which will be further facilitated through piloting the capacity building programme in min. 100 public procurement related staff and workforce, delivering all data and information collected in the framework of the previous outputs and providing/ delivering relative policy recommendations to a growing number of key stakeholders and public authorities (min. 40).The target groups addressed range from Public Authorities, contracting Authorities in local, regional, National level, including Public procurement staff, to key stakeholders representing the construction sector, policy makers, social partners and entities involved in procurement processes, as well as education’s sector stakeholders, including training and adult learning providers.The envisioned impact will be enabled through the involvement of 5 project partners, coming from 4 EU countries: France, Slovenia, Greece, Ireland, that represent the construction sector, the education sector as well as public authorities in regional and national level. Their complementary backgrounds and expertise, familiarity with the project topic and close proximity with the target groups will ensure the projects’ high sustainability, dissemination and exploitation impact.
