Why choose a Green Roof?
Australian cities like Melbourne and Sydney are increasingly facing the impacts of climate change – from extreme heatwaves and heavy rainfall to more frequent bushfires and flooding. According to recent polls, a majority of Australians (59%) see climate change as a critical threat. In response, many cities are turning to green infrastructure as a vital solution. Among these, green roofs – also known as living roofs – stand out as an effective and visually appealing way to cool urban environments, improve stormwater management, and enhance urban biodiversity. By integrating more green rooftops and roof gardens into dense cityscapes, Melbourne and Sydney are leading the way in building more liveable, resilient, and future-proof cities.
Sydney leads the way in urban greening
Since 2014, the City of Sydney has been a national frontrunner in promoting green roofs and living green walls as essential tools for climate adaptation and sustainable urban development. Through its progressive Sustainable Sydney 2030 strategy, the city has made a long-term commitment to increasing green infrastructure to create a healthier, more resilient and more liveable urban environment.
In Sydney, green rooftops are no longer a luxury – they are a necessity. From new high-rise developments to the retrofitting of older buildings, green roof systems and sustainable rooftop gardens are being integrated into the cityscape to reduce the impacts of heatwaves, manage stormwater, improve air quality, and support local biodiversity.
The city actively encourages the private sector, developers and building owners to invest in green roof solutions through planning incentives, roof planting ideas and public awareness initiatives. This shift reflects a growing recognition that green roofs in Sydney offer more than aesthetic value – they are a vital part of the solution to urban heat, climate resilience, and sustainable living.
Melbourne's ‘Green Our City Action Plan’
Melbourne is taking concrete steps toward a greener, more climate-resilient future through its Green Our City Strategic Action Plan. This forward-thinking plan places strong emphasis on expanding green infrastructure, including green roofs, vertical greening systems and sustainable roofing design, to enhance the city’s liveability, sustainability and biodiversity.
By actively collaborating with the private sector, construction industry and developers, the City of Melbourne aims to accelerate the adoption of green roofing, link biodiverse green roofs, in both new and existing buildings. Key initiatives include the promotion of green rooftop benefits, sharing of data and resources, and updates to planning schemes to make green rooftops, roof gardens and sustainable roof designs a standard feature in urban development.
