The what and why of certification 

Green Star is Australia's trusted mark of quality for the design, construction and operation of sustainable buildings, fitouts and communities. Choosing Green Star can help you save money, create a healthy place for people, minimise your environmental footprint and build a better future for us all.

Our built environment is currently the world's single largest contributor to greenhouse gas emissions, and also consumes around a third of our water, and generates 40 per cent of our waste. From individual buildings to entire communities, Green Star is transforming the way our built environment is designed, constructed and operated. Launched by the Green Building Council of Australia in 2003, Green Star is Australia's only national and voluntary rating system for buildings and communities. Green Star is helping to improve environmental efficiencies in our buildings, while boosting productivity, creating jobs and improving the health and well-being of our communities.

Whether you're a building owner, operator or occupant, creating a green community or looking to live more sustainably, Green Star offers a framework of best practice benchmarks for sustainability that you and the marketplace can trust.
