Tackling the complex challenges and opportunities related to infrastructure resilience and maintenance requires a multidimensional approach, considering a range of factors and stakeholders at the local, regional, national and global level. This approach seeks to get the best out of the asset over its life cycle, across functions and tasks and the entire infrastructure system/network. As infrastructure is inevitably affected by environmental social and governance (ESG) risks, this approach can identify the trade-offs between objectives, and therefore enable more robust policy choices.

Drawing on examples and case studies, this report aims to provide a framework to optimise existing infrastructure assets and build new resilient infrastructure, including new strategies capable of ensuring quality and performance over the asset life-cycle. 

It also aims to support the development of the G20 Policy Agenda on Infrastructure Maintenance presented by the Italian presidency at the G20 Ministries of Finance and Central Banks meeting in July 2021.
