Infrastructure Sustainability Council

What Infrastructure Sustainability Council does

The Infrastructure Sustainability Council (ISC) is a member-based, purpose-led non-profit organization headquartered in Sydney, Australia, operating across Australia and Aotearoa New Zealand to advance sustainability outcomes in infrastructure. Its core offering is the IS (Infrastructure Sustainability) Rating Scheme, an evidence-based framework comprising IS v2.1 Planning, IS Essentials, and IS v2.2 Design & As-Built tools that measure, assess, and drive improvements in the sustainability performance of infrastructure projects and assets. Since 2012, more than $201 billion AUD of infrastructure projects have involved an IS rating, positioning ISC as the de facto sustainability ratings body for the ANZ infrastructure sector.

ISC monetizes through four primary streams: annual tiered organizational membership fees (subscription), per-project IS Rating registration fees (professional services), learning and accreditation programs led by the ISAP (Infrastructure Sustainability Accredited Professional) credential and complementary micro-credentials (subscription), and ISupply directory listing fees from sustainable product and service suppliers seeking access to IS-rated projects (subscription). The organization serves a vertically-segmented customer base spanning government asset owners, utilities, tier-one contractors, engineering consultancies, financial institutions, and product suppliers.

Go-to-market is community-led, anchored by the ISC Connect Conference, ISC Awards, ISAP accreditation, member committees, webinars, and advocacy publications including Modern Slavery Coalition outputs and IS Impact Notes. The 2025 Strategy 2030 roadmap and recent partnerships (AURIN, Jacobs/Honeywell/Sydney Water Digital Infrastructure Futures, Connellgriffin) indicate active expansion of the rating scheme into adjacent verticals such as digital infrastructure and sustainable procurement. Pricing is not publicly disclosed and is accessed through the member portal.

Direct peers

• BRE Group (BREEAM): BRE Group operates BREEAM, one of the world's most established sustainability rating/certification schemes for built environment and infrastructure projects. Comparable to ISC because both operate member-based ecosystems around evidence-based sustainability rating frameworks applied to infrastructure assets.
• Carbon Trust: Carbon Trust provides sustainability certification, carbon footprinting, and advisory services globally. Comparable to ISC as an evidence-based sustainability certification body, though broader in scope (carbon, products, supply chain) rather than infrastructure-specific.
• Institute for Sustainable Infrastructure (ISI) - Envision: ISI administers the Envision rating system for sustainable infrastructure in North America. Directly comparable to ISC because Envision and IS Ratings are both third-party, evidence-based sustainability rating schemes specifically designed for infrastructure projects and assets.
• CEEQUAL: CEEQUAL is the UK and international sustainability rating and assessment scheme for civil engineering and infrastructure. Comparable to ISC because it provides evidence-based sustainability certification specifically for infrastructure projects across planning, design, and construction phases.

Emerging players

• EcoVadis: EcoVadis provides sustainability ratings and scorecards for companies and supply chains. Comparable to ISC as a sustainability assessment/rating platform that monetizes ratings via subscriptions, though focused on corporate supply chains rather than infrastructure assets.

Regional players

• Green Building Council of Australia (GBCA): GBCA operates the Green Star rating system for buildings in Australia. Comparable to ISC as an ANZ-based, member-driven sustainability rating organization, though focused on buildings rather than horizontal infrastructure.
• New Zealand Green Building Council (NZGBC): NZGBC is the New Zealand member of the World Green Building Council network, administering Green Star NZ and Homestar. Comparable to ISC as an ANZ member-based sustainability rating body, though focused on buildings and homes rather than infrastructure.

Broad incumbents

• Global Reporting Initiative (GRI): GRI sets the most widely used global sustainability reporting standards, including for infrastructure and construction. Comparable to ISC as the upstream sustainability standards body whose frameworks increasingly complement or compete with rating schemes like IS Ratings.
• U.S. Green Building Council (USGBC) - LEED: USGBC administers LEED, the world's most widely used green building rating system. Comparable to ISC as a global, member-based sustainability rating organization with a dominant regional framework, though focused on buildings rather than infrastructure.

Others

• World Business Council for Sustainable Development (WBCSD): WBCSD is a global, CEO-led membership organization advocating for sustainable business. Comparable to ISC as a member-based sustainability advocacy and standards organization, though broader in scope and without an infrastructure-specific rating scheme.
