ISCA principally advances sustainability outcomes in infrastructure through the development and facilitation of the IS rating scheme. IS rating scheme is an industry-compiled, voluntary sustainability performance framework evaluating planning, design, construction and operation of all infrastructure asset classes. The IS rating scheme is Australia and New Zealand’s only comprehensive standard for evaluating sustainability across design, construction and operation of infrastructure.

As of July 2019, there are 213 ratings registered with IS, corresponding to assets totalling over $160 billion in capital value.
