The life-cycle of infrastructure assets and the public and private investments that enable them play out over a longer timeframe than many others, and this longer-term exposure increases the importance of whole-of-life thinking and risk management.
The large immediate impacts of infrastructure project construction on ecosystems and communities, the long-term economic planning that is underpinned by infrastructure projects and the risks posed by climate change over the same timeframes bring the stakes at play into stark relief. An eco-system of rating tools and reporting frameworks exists for projects in the built environment, including infrastructure assets. However there is no single tool that extends on the one hand through Planning, Design, Construction and Operations stages of a project and also allows performance to be aggregated at each of the asset, fund and institutional investment scale.
This Discussion Paper provides an assessment of the links between the IS rating tool administered by the Infrastructure Sustainability Council of Australia (ISCA) and the Global Real Estate Sustainability Benchmark (GRESB) Assessment for Infrastructure Assets and Funds.
