Adelaide is investing $5m in its efforts to green the central business district (CBD) with initiatives including targeted street plantings, green wall and roof grants, a new “cool corridor” and $500,000 worth of green water rebates.
Led by Green Adelaide the aim is to create a cooler, greener, wilder and more climate-resilient CBD and boost the city’s livability. Projects will be delivered over the next four years.
Heat and tree canopy mapping
The $2m greener streets programme will be dedicated to specific greening of CBD streets based on heat and tree canopy mapping put together through joint state and local government investigations. The $1m cool corridor programme aims to create a “green artery” of streets and laneways through the heart of the CBD, via strategically selected locations.
“South Australia is national leader when it comes to taking action to deal with our changing climate,” said David Speirs, minister for environment and water, who showcased some of the city’s efforts in this area at the Cop26 climate change conference.
He added: “These new and innovative greening projects for Adelaide’s CBD are further examples of this commitment and they will reduce temperatures around parts of the city, improve livability and increase economic activity.
“Heat mapping data has been used to determine the warmest areas of the CBD and we will partner with the City of Adelaide to make a focused effort to green and cool these areas through planting trees and other plants and building green roofs and walls.
“The Cool Corridor is a vision for a green walkway through the heart of the city through multi-use paths, shade and greenery that creates a more attractive and cooler city space for everyone to enjoy.
“Green walls and roofs are an effective and alternative way to improve the visual amenity of the city, which improves wellbeing and encourages people to spend more time in an area which helps stimulate our economy. They are also a way to reduce heat impacts where there is little space for street trees and parks.”
The $1.5m wild walls and roofs grants will provide CBD building owners with up $25,000 to build green walls and roofs on commercial and residential dwellings, and the green water rebates will trial the application of discounted water rates for new projects that are designed to cool and green Adelaide’s CBD.
“We know that greening and cooling our city makes good sense for the community, but the cost of water can be a deterrent in some cases,” said minister Speirs.
“The green water rebates trial is expected to further encourage greening and cooling projects by investigating the impact that discounting the cost of water can have on these types of projects.”

Green Adelaide Board presiding member professor Chris Daniels said that these new programmes are another way Green Adelaide is partnering with others to deliver on-ground action as a contribution to Adelaide’s push to become an internationally-known National Park City.
“These inner city areas can play a valuable part in conservation, with trees along Leigh Street in the city already supporting the largest known roosting aggregation of native tree martins in South Australia,” said professor Daniels.
Green Adelaide is a South Australian Government-supported organisation and it will work on the initiatives in partnership with the City of Adelaide and other councils, SA Water and Escosa. The planning for the programmes is expected to begin from early 2022.
