Harnessing the Power of Public-Private Partnerships: The role of hybrid financing strategies in sustainable development

This report by the International Institute for Sustainable Development (IISD) examines the theoretical benefits and practical drawbacks of Public-Private Partnerships (PPPs), specifically focusing on their ability to integrate into sustainable development frameworks. It argues that while PPPs can attract capital and encourage life-cycle technology investments, they often suffer from high costs, reduced transparency, and a lack of explicit sustainability safeguards.

• Theoretical benefits of PPPs include increased value for money through private sector efficiency, faster project delivery via risk transfer, and expanded government access to off-balance sheet financing. Additionally, because private partners are responsible for the entire life cycle of the infrastructure, they may be more inclined to invest in the best available technologies.
• Practical drawbacks of the PPP model include high tender costs, complex contracts, and a requirement for high skilled capacity in both sectors to avoid rigid agreements. These complexities can lead to implementation delays and increased costs for consumers, while the model generally undermines public sector transparency and accountability.
• Governments are currently not using PPPs to advance social and environmental sustainability, as private partners primarily respond to technical specifications in tenders. To achieve sustainable development, governments must lead during the tender and contracting stages and reform norms regarding risk transfer and compensation to provide correct incentives for sustainability investments.
• Integrating sustainability into PPPs requires a 'whole life value approach' and the adoption of sustainable public procurement policies. Current PPP designs often fail to prioritize transparency, accountability, and whole life costing, and frequently lack explicit tests to measure standalone environmental or sustainable risks and benefits.
