Who We Are

Infrastructure Sustainability Council of Australia (ISCA)

Accelerating Sustainability in Infrastructure Through Collaboration

The Infrastructure Sustainability Council of Australia (ISCA) is a member-based, not-for-profit peak body operating in Australia and New Zealand with the purpose of enabling sustainability outcomes in infrastructure.  We do this in the following ways;

  • With an Infrastructure Sustainability (IS) rating scheme for planning, design, construction and operations of infrastructure assets,
  • Education, training and capacity building,
  • Connecting suppliers of sustainable products and services with projects through ISupply,
  • Bringing together experts to share knowledge and lift the community of practice,
  • Recognition and rewarding best practice.

ISCA’s greatest strength is our community of engaged stakeholders – we have a great deal of expertise within our network of members. We position ourselves as a network for collaboration, discussion and education. Our regular events, conferences and seminars facilitate knowledge sharing, and enable experts to get together in a focused environment.

Sustainable Procurement Policy

We at ISCA recognise that our purchasing power can be utilised to encourage good practices through the supply chain, add value to the organisation by encouraging communication and innovation in the supply chain, and achieve social and environmental benefits whilst also reducing costs. ISCA’s procurement policy has been developed to align with the recently released ISO 20400:2017 Sustainable Procurement framework and the ISv2.0 Sustainable Procurement category.


The Infrastructure Sustainability (IS) Rating scheme facilitates the ratings of infrastructure projects and assets. The IS Rating scheme is Australia and New Zealand's only comprehensive rating system for evaluating sustainability across design, construction and operation of infrastructure.

Read more about the IS Rating Scheme.

We were founded in 2007 as the Australian Green Infrastructure Council (AGIC) after a collaboration by nineteen industry organisations.

We evolved into ISCA in 2012, and since then over $80 billion in infrastructure and civil works projects have become engaged in the IS rating program.

Read more about ISCA's history and founding members.

We now have over 100 Organisational members. In 2017, we launched the IS International Rating tool, and the IS Operations tool.

“When we plan, design, build or maintain infrastructure, we’re not just dealing with an asset, we're providing services to a range of communities of interest (economic, social and cultural).  We also have the opportunity to protect and grow environmental, social, cultural and economic capital, as well as manufactured capital.

The IS framework supports holistic, integrated thinking and action and we have an awesome international community of practice.

“Get in touch if you want to do more with your asset investment or to explore the application of IS to planning, design, construction or operations.” – Monique Cornish, ISCA Board member.
