Green Public Procurement (GPP), the practice of aligning environmental sustainability with the purchase of goods, services, and works by public entities, is gaining global traction as a policy tool for the achievement of the Sustainable Development Goals. This chapter maps the current state of GPP implementation in Lebanon to date by highlighting the legal framework, the implementation patterns across sectors and governments, as well as the key impediments and opportunities ahead. Lebanon’s GPP journey is still nascent: while the groundwork had been laid by the Institut des Finances Basil Fuleihan starting 2010 and while a new Public Procurement Law (No. 244/2021) has recognized and enshrined sustainability principles by law, practical uptake has nonetheless remained limited. The chapter finds that the implementation of GPP in Lebanon has been driven by individual initiatives and donor-supported projects, whereas systematic nationwide adoption has not been achieved. Major barriers include lack of mandatory requirements and implementation frameworks, capacity gaps, market constraints, economic as well as political challenges. Nevertheless, emerging opportunities are on the horizon: the new procurement law and national reform strategy have paved the way for the rollout of implementation frameworks. This would create a window of opportunity for GPP integration into public tenders. International best practices show that clearly delineated mandates alongside political commitment can rapidly expand green purchasing. Beyond its sustainability-related considerations, GPP can also help Lebanon reduce the energy bill that drained its public finances and develop green industries, both of which will contribute to the country’s recovery and reconstruction.
