Green Building Council of Australia Sustainability Actions

Runs the Green Star rating system

GBCA developed and runs Green Star, an Australian sustainability rating system for buildings, fitouts, communities, and homes. The system checks projects against set criteria and only certified projects can use the Green Star trademark. GBCA says this helps make sustainability claims more reliable because projects are independently assessed rather than just self-rated.

Expanded Green Star tools

GBCA has launched and updated several Green Star tools, including Green Star Buildings, Green Star Homes, Green Star Interiors, Green Star Performance, and Green Star Communities. These tools are meant to cover different project types, from new buildings to existing buildings and neighbourhood-scale developments. The updates show that the rating system keeps changing as building standards and climate expectations change.

Published anti-greenwash guidance

GBCA has updated its marketing rules and guidance to reduce misleading sustainability claims. It warns that projects should not claim Green Star status unless they are actually certified. The organisation also says that self-assessments are not the same as verified certification, which helps explain the difference between a claim and a checked result.

Launched data centre program

In 2026, GBCA launched a Sustainable Data Centres program with Data Centres Australia. The program is meant to explore better sustainability standards for the design, construction, and operation of data centres. GBCA says the work will look at energy, water, circularity, nature, and community impacts, and will be shaped with industry input.

Trains and educates industry

GBCA runs courses, forums, newsletters, and other learning resources for people working in the built environment. Its education work covers topics such as sustainable procurement, refrigerants, air tightness, and Green Star use. This helps builders, designers, and decision-makers understand how to apply sustainability ideas in real projects.

Advocates for policy change

GBCA says it advocates for policies and programs that support sustainable buildings and communities. It also works with government and industry to help Green Star fit into wider rules and planning systems. This kind of advocacy can make it easier for sustainable design to move from niche projects into mainstream practice.

Promotes verified certification

GBCA has stressed that Green Star certification is a quality process accredited to ISO 9001:2015, an international standard for managing quality. It says only certified projects can claim Green Star status, and that this helps protect against greenwashing, which means making sustainability claims that are not properly backed up.
