Public-private partnerships (PPPs) have emerged as critical enablers of sustainable infrastructure development, particularly in the context of decarbonization and climate resilience. According to the World Bank, the construction and operation of infrastructure are responsible for approximately 70% of global greenhouse gas (GHG) emissions (World Bank, 2021a). As global infrastructure demands escalate, ensuring that these projects are designed to be energy-efficient, low-carbon, and resilient to climate impacts is imperative for addressing both the climate crisis and the growing infrastructure deficit. This white paper examines the role of PPPs in driving sustainability and decarbonization in infrastructure projects, with a focus on the integration of climate-resilient solutions and the reduction of carbon footprints. It investigates how legal frameworks, innovative financing models, and new policy tools have facilitated the adoption of low-carbon infrastructure solutions in PPP projects. Furthermore, it discusses the emerging practices in the design and implementation of these partnerships, emphasizing the role of PPPs in fostering climate-smart infrastructure that contributes to the achievement of global sustainability targets. As the world continues to confront the challenges posed by climate change, the potential of PPPs to support resilient, low-carbon infrastructure has never been more critical.
