What is the Infrastructure Sustainability Council’s IS rating scheme?

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. ISCA seeks to promote infrastructure sustainability through the development and operation of the Infrastructure Sustainability (IS) rating scheme.

The IS rating scheme is a comprehensive ISCA rating system for evaluating sustainability across the planning, design, construction, and operational phases of infrastructure programs, projects, networks, and assets.  IS evaluates the sustainability performance of the quadruple bottom line (Governance, Economic, Environmental and Social) of infrastructure development.

The Infrastructure Sustainability Council’s IS rating scheme aims to:

  • Provide a common national language for sustainability in infrastructure.
  • Provide a framework for consistent application and evaluation of sustainability in tendering processes.
  • Help in scoping whole-of-life sustainability risks for projects and assets, enabling smarter solutions that reduce risks and costs.
  • Foster efficiency and waste reduction, reducing costs.
  • Foster innovation and continuous improvement in the sustainability outcomes from infrastructure.
  • Build an organisation’s credentials and reputation in its approach to sustainability outcomes.

Support to achieve an IS Rating

We have two accredited Infrastructure Sustainability Accredited Professionals (ISAPs) on our team, Director Hannah Meade and Senior Consultant Juliana Bedggood who assist businesses to successfully navigate the IS process and achieve an IS rating.

ISAPs are accredited to:

  • Explain the key concepts and costs and benefits of the IS rating scheme.
  • Prepare an IS rating scheme strategy and implementation plan.
  • Identify key components of the IS rating process to complete a self-assessment for a registered rating.
  • Define a base case and complete a base case proposal ready for verification.
  • Find key information in the IS Technical Manual.
  • Interpret IS categories and credits and describe appropriate evidence for the pursuit of a certified IS rating.

Additionally, we can assist with IS Rating Project Management, working closely with Assessors to guide the project teams through the IS rating process, including providing strategic advice; liaising with ISCA; organising and submitting all evidence and documentation; as well as building organisational capacity.

Our infrastructure sustainability experience

Our depth of experience in the infrastructure sector, in addition to our expertise in environmental and social sustainability, means our team has the knowledge and capability required to achieve success on a wide range of industry projects.

We’ve been engaged by Federal and State Government departments for a range of technical and strategic projects, including emissions assessments of infrastructure, construction, vehicles, and equipment, along with relevant emissions reduction options and business cases. Other infrastructure sector experience includes working with organisations such as Lendlease, Fulton Hogan, and John Holland on climate risk and Task Force on Climate Related Financial Disclosures (TCFD) workshops; emissions reporting under National Greenhouse and Energy Reporting Scheme (NGERS) and the National Pollutant Inventory (NPI); and energy auditing and reduction strategies.

As infrastructure is such a vital part of how we interact as a society, ensuring infrastructure is managed in a sustainable way, is important for its contribution to sustainable outcomes and its symbolic role in a greater move towards sustainability.
