The substantial impact that climate change will have on infrastructure makes it particularly important to incorporate this risk into our long-term planning and management.

The Office of Environment and Heritage (OEH) has supported the Infrastructure Sustainability Council of Australia’s (ISCA) development of a Sustainability rating tool.

ISCA's Guideline for Climate Change Adaptation (PDF 765 KB) can be used to help infrastructure designers, engineers and builders to measure and manage vulnerability to future climatic conditions. The guideline applies to all stages of the infrastructure life cycle and will help ensure that roads, dams, bridges, water supply and wastewater systems are resilient to the future impacts of climate change. The North West Rail Link construction, for example, is using the rating system to inform design, contracting and operation.

NSW Treasury has prepared guidelines for the economic appraisal of assets and infrastructure assessments in terms of climate change. Potential risks to public assets from climate change should be considered in the context of the NSW Treasury guidance framework outlined in:

Adaptation for Sydney’s water

Balancing Greater Sydney's water supply and demand over the long term requires an understanding of climate cycles and trends and of the potential effects of climate change.

The AdaptWater tool (PDF 345 KB) used by Sydney Water quantifies the adaptation options for water assets. It provides a comprehensive review of the complex direct and indirect risks, along with flexible adaptation pathways and estimates of their cost effectiveness.

The NSW Government's 2010 Metropolitan Water Plan concentrated its adaptive planning on four major areas: dams, recycling, desalination and water efficiency. More information on Sydney’s water infrastructure is available at Water for Life.
