More:Concrete jungle: Push to grow more green spaces across Sydney
Sydney has recently become home to the biggest green wall installation in Australia, amid a wider campaign to green the cityscape. Currently 15.5 per cent of Sydney is blanketed in green canopy, but the city council wants to increase coverage to 23.5 per cent by 2030.
There are similar campaigns in other Australian capitals and an even wider global trend to boost the number of green spaces in urban centres.
Green roofs and walls project officer at City of Sydney council, Lucy Sharman, says the city is on track to reach its green canopy target, but more green roofs and walls need to be installed.
"There is an absolute fascination with green roofs and walls at the moment," she said.
"Green walls started to go in in the 1930s... but in the last 10 years there's been around almost a 70 per cent increase in green roofs and walls."
