This report by the NewClimate Institute examines the potential for Green Public Procurement (GPP) to reduce energy consumption and greenhouse gas emissions in public buildings by replacing conventional air conditioners with Green ACs, while identifying the financial, political, and technical barriers to adoption.

This report details the outcomes of the ENHANCE project (2017-2020), an Interreg Europe initiative designed to improve regional policy instruments that support the EU Eco-Management and Audit Scheme (EMAS) to increase resource efficiency and promote the circular economy. The project involved six partners across Europe who identified 24 good practices and implemented 31 actions, primarily focusing on regulatory reliefs and promotional incentives for EMAS-registered organizations.

This report by the Stockholm Environment Institute analyzes the implementation of Green Public Procurement (GPP) in Tallinn, Estonia. It evaluates the current state of procurement within city agencies, identifies systemic barriers—such as lack of time and expertise—and compares Tallinn's approach with other Nordic and Dutch cities. The document concludes with a four-stage strategic roadmap to increase the prevalence of environmental criteria in city contracts.

This report uses a system dynamics model to quantify the economic, social, and environmental impacts of Green Public Procurement (GPP) in Canada from 2016 to 2035. It analyzes four spending categories—buildings, cement, steel, and vehicles—comparing business-as-usual (BAU) scenarios against sustainable and domestic-production scenarios. The findings generally indicate that GPP reduces long-term operating costs and greenhouse gas emissions while potentially increasing domestic employment and revenue.

This case study describes the 'GPP in Bhutan (GPPB)' project led by the International Institute for Sustainable Development (IISD). The project aimed to scale up green public procurement (GPP) in Bhutan by providing research, policy support, training for civil servants and suppliers, and technical assistance for pilot infrastructure projects to align public spending with sustainable development goals.

This fact sheet outlines the economic and environmental benefits of Green Public Procurement (GPP) based on the IISD GPP model, highlighting that GPP can offset its own costs through energy, health, and environmental savings.
