The ISupply Directory


Join the ISupply program

ISupply connects sustainable products and services with projects and assets undertaking an IS rating.

For Projects & Assets

The ISupply directory will give you access to suppliers that can help your project or asset achieve sustainability outcomes rewarded under the IS rating scheme. The directory links products and services to IS credits helping you identify suppliers that can meet your requirements.

For Suppliers

Becoming an ISupplier will showcase your product and service to small and large infrastructure projects and assets undertaking the IS rating across Australia and Aotearoa New Zealand. IS rated projects represent approximately 20% of the engineering construction sector and ~75% of large and mega Government infrastructure projects in Australia and are increasingly gaining traction in Aotearoa New Zealand. It is mandated by almost all Australian State Government transport agencies as well as a number of Local Governments and other infrastructure delivery agencies. That means your product/service will be in front of some of the largest infrastructure projects across Australia and Aotearoa New Zealandd. To date, ISCA has rated over $150 billion worth of infrastructure since 2012.

As part of the ISupply program, material suppliers can have their branded products included in the ISv2.0 Materials Calculator. To do this, your products will need to have an EN15804 compliant EPD. Fees to include your branded product in the ISv2.0 Materials Calculator are provided in the ISupplier Guide.
