Sustainability has moved from a nice-to-have to a core criterion in event procurement. Clients ask about it in briefs. Attendees notice it on the day. And as the events industry takes a harder look at its environmental footprint, one certification keeps coming up: Green Star.
But what does Green Star certification actually mean for events? It is not a straightforward question. The scheme was designed primarily for buildings and communities, not live event delivery. Yet it shapes the venues, suppliers, and procurement decisions that sit at the heart of sustainable event management.
This article explains what Green Star certification covers, how it applies in an events context, and what it means in practice when you are planning eco-friendly events that genuinely stand up to scrutiny.
What Is Green Star Certification?
Green Star is Australia’s national sustainability rating system, administered by the Green Building Council of Australia (GBCA). It was established in 2003 and has since become the recognised standard for measuring the environmental performance of buildings, fitouts, and communities.
The Australian Green Star rating system awards projects a score from one to six stars. A four-star rating indicates best practice. Five stars signals Australian excellence. Six stars represents world leadership.
Ratings are awarded across several categories:
- Management and governance
- Indoor environment quality
- Energy performance
- Transport and connectivity
- Water consumption
- Materials and waste
- Land use and ecology
- Emissions and innovation
Green Star accreditation is independently verified, which means claims are not self-reported. That matters when you are selecting a venue or supplier and need to back your sustainability commitments with evidence.
Green Star and Events: Where the Overlap Sits
Green Star does not certify events as events. The scheme certifies the built environment: the venue, the fitout, the precinct. But that distinction is more useful than it might first appear.
When your event is held in a Green Star certified venue, you are immediately working within a building that has been assessed against rigorous environmental benchmarks. That covers the energy systems, water infrastructure, waste management facilities, and air quality of the space itself.
Choosing a certified venue is one of the most impactful decisions an event planner can make. It is also one of the more defensible ones. Rather than relying on a venue’s marketing language, a Green Star rating gives you a verified standard to reference. This is particularly relevant for clients who include sustainability criteria in their event management briefs or who need to report against ESG commitments.
Certified Venues Across Australia
Australia has a substantial number of Green Star certified buildings, with major event venues in Sydney, Melbourne, and Brisbane among them. Venues such as the International Convention Centre Sydney (ICC Sydney) and the Melbourne Convention and Exhibition Centre (MCEC) hold Green Star ratings, which means event planners already have access to high-quality, certified infrastructure.
When sourcing a venue, asking for Green Star documentation is a reasonable and increasingly common part of the venue selection process. A venue that cannot provide it is not necessarily unsustainable, but one that can offers a stronger, independently verified baseline.
What Green Star Does Not Cover
Understanding the limits of Green Star certification is as important as understanding what it includes.
The rating covers the building. It does not cover what happens inside it on your event day. The catering, the waste generated by attendees, the carbon footprint of travel, the materials used in your set build, the sustainability of your suppliers: none of these fall within the Green Star scope.
This is not a criticism of the scheme. It was not designed to cover event operations. But it does mean that if your goal is genuinely sustainable events, a Green Star venue is the foundation, not the finished product.
Complementary practices such as waste reduction strategies, sustainable procurement, and supplier selection all require separate consideration. Our article on sustainable event management covers these operational practices in detail.
How to Build Green Star Thinking Into Your Event Plan
If you want your event to reflect genuine commitment to sustainability, rather than just holding it in a certified building, here is where to focus.
Venue Selection
Start with Green Star certified venues as your default shortlist. Check the GBCA website for the current register. Verify that the rating applies to the specific space you are using, not just another part of the building.
Supplier Alignment
Ask your suppliers about their own sustainability credentials. Not all will have formal certification, but a catering company that sources locally, a production supplier that uses LED lighting and reusable infrastructure, or an AV partner with an active carbon reduction plan all contribute meaningfully to the overall event services picture.

Waste and Materials
Set a target for waste diversion before the event begins. Assign responsibility for waste sorting and make sure the venue’s infrastructure (bins, collection points, composting facilities) is actually accessible and well-signed on the day. A Green Star building may have excellent waste systems in place, but they only work if your event activates them correctly.
Measurement and Reporting
If your client needs to report on sustainability outcomes, set up measurement criteria at the planning stage. Track energy consumption, waste volumes, supplier certifications, and transport data. These metrics matter increasingly in brand activation and corporate event contexts where ESG reporting is a genuine obligation.
Why Green Star Matters More Now
The events industry in Australia is under real pressure to reduce its environmental impact. Clients across the corporate, government, and not-for-profit sectors are being asked to demonstrate sustainability in their spending. Events are visible and often scrutinised.
Green Star certification offers a credible, independently verified language for that conversation. It does not solve every sustainability challenge in event management. But it provides a recognised benchmark that clients and planners can both point to.
The strongest events are ones where sustainability is designed in from the start, not bolted on at the end. That applies to the venue choice, the supplier relationships, the materials brief, and the guest experience. As we explore in our piece on crafting unforgettable experiences, the decisions made at the planning stage shape everything that follows. [INTERNAL LINK]
Events and sustainability are not competing priorities. With the right foundations in place, they reinforce each other.
FAQs
Green Star is Australia’s national sustainability rating system, run by the Green Building Council of Australia (GBCA). It assesses and certifies buildings, fitouts, and communities against a set of environmental performance criteria covering energy, water, materials, indoor quality, and more. Ratings run from one to six stars, with six representing world leadership in sustainable design and operation.
Green Star certifies buildings and spaces, not events themselves. However, it is directly relevant to events because it sets the sustainability baseline for the venues you choose. Holding an event in a Green Star certified building means you are working within independently verified, sustainable infrastructure. What happens operationally within that space, such as catering, waste management, and supplier choices, requires separate planning.
Eco-friendly event planning involves making deliberate choices at every stage of the planning process to reduce environmental impact. This includes selecting certified venues, working with suppliers who share sustainability values, designing out waste, minimising single-use items, and measuring outcomes. It is a discipline that begins at the brief stage, not a checklist applied after the event plan is already set.
Start with your venue. A Green Star certified venue gives you a verified sustainable foundation. Beyond that, focus on supplier selection, waste reduction targets, reducing single-use materials, and choosing catering partners who prioritise local sourcing and low-waste operations. Set measurable targets before the event and track outcomes against them. Sustainability works best when it is built into the brief, not added at the last minute.

Plan Events That Stand for Something
Green Star certification is one piece of a larger sustainability picture. It matters because it provides a credible, independently verified standard for the built environments where events take place. But it sits alongside, not instead of, the operational decisions that determine how sustainable your event actually is.
The planners and organisations leading on sustainability are the ones treating it as a design principle, not a compliance exercise. They are choosing certified venues, asking harder questions of their suppliers, and measuring what they commit to.
