In this book, governing infrastructure sustainability is explored using the Sydney Metro Authority in Australia and the London 2012 Olympic Delivery Authority's transport division as case studies. Infrastructure sustainability pertains to minimising negative impacts and maximising opportunities across environmental, social and economic dimensions in the delivery phase of infrastructure. Each case study approach to governing infrastructure sustainability is categorised under six key components: i) overall structure, ii) interface with planning approval, design and procurement processes, iii) roles and responsibilities, iv) decision-support tools, v) measuring, monitoring and reporting, and vi) knowledge-sharing and capacity building. A framework is developed based on the analysis that provides guidance on governing infrastructure sustainability. The framework helps fill a gap in the academic literature and provides an approach for sustainability advisers and other industry professionals to adopt on real-life infrastructure projects. This book will therefore be of interest and value to both academic researchers and infrastructure industry professionals.
