The Infrastructure Sustainability Council of Australia (ISCA) is the peak body for advancing sustainability outcomes in infrastructure. Among other things, they specialise in performance based, industry-led reporting and governance, and are the custodians of the IS Rating Scheme. The IS Rating scheme, called IS for short, is a voluntary sustainability performance rating scheme. IS evaluates and drives performance beyond compliance, across the asset lifecycle from planning, design and construction to operation of all infrastructure asset classes. So far over $83.5B worth of infrastructure projects and civil works in Australia and New Zealand have been certified or are registered for an IS Rating.
We are very proud to say that late last year our NorthConnex project achieved Australia’s highest ISCA rating for a road project to date. It received the ‘Leading’ design rating, the highest grade in ISCA’s scheme and was a finalist for the 2016 Asset Achievement Award, in recognition of key design outcomes including a:
- 26% reduction of scope 1 and 2 carbon emissions
- 42% reduction in total water use over the life of the project
- 29% reduction in the life cycle impact of materials.
Our approach to sustainable project development was recognised more recently with our Gateway Upgrade North and the CityLink Tulla Widening projects both being awarded ‘Excellent’ IS ratings this year.
With four of Transurban’s Australian projects currently using the ISCA IS rating scheme – the Logan Enhancement Project being our fourth - and West Gate Tunnel Project committed to its use in the near future, we aim pretty high. In fact, we always strive to achieve a minimum of an ‘Excellent’ infrastructure sustainability rating for all major Australian development projects.
For us, IS is not only about driving strong sustainability performance on our projects, it’s also about encouraging and challenging our industry to look at more sustainable ways of designing, building and operating road assets.
