We're aiming to increase Greater Sydney's tree canopy to 40% by 2030 by planting more trees in streets, parks, bushland areas and yards.
That’s more trees in our streets, parks, backyards, neighbourhoods and schools, so we can grow our tree canopy from 16.8%* to 40% (*source Office of Environment and Heritage, 2011).

Sustainable Sydney 2030 outlined the aspiration of our community and businesses for our local government area to be an environmental leader on a global scale. To guide the implementation of Sustainable Sydney 2030, the City developed a series of environmental master plans and strategies between 2008 and 2015. This strategy and action plan combines the insights and data from these documents.

Water's role in liveability: Heat, Waterways and Urban Amenity

Australian cities contain millions of trees that provide amenity, important ecosystem services such as cooling and slowing stormwater, and provide habitat for birds and animals. There is growing recognition that increasing temperatures due to urban heat and climate change are a threat to some tree species in our cities.

Greenhouse gas emissions urgently need to be reduced. Even with a step up in mitigation, the goal of limiting global temperature rise to well below 2 °C remains challenging. Consequences of missing these goals are substantial, especially on regional scales. Because progress in the reduction of carbon dioxide emissions has been slow, climate engineering schemes are increasingly being discussed.

As the frequency and intensity of heatwaves are growing in Australia, strategies to combat heat are becoming more vital. Cities are exposed to urban heat islands (UHIs) due to excess urbanisation. In this study, a definition of urban heatwave (UHW) is conceptualised to investigate the combined impacts of heatwaves and UHIs.

This report provides an in-depth analysis of the costs and benefits of applying a set of smart surface solutions1 , including cool roofs, green roofs, solar PV, and permeable and reflective pavements and road surfaces across three cities: El Paso, Philadelphia and Washington, D.C.

Cities must address climate change. More than half of the world’s population is urban, and cities emit 75% of all carbon dioxide from energy use1. Meeting the target of the 2015 Paris climate agreement to keep warming well below 2° C above pre-industrial levels requires staying within a ‘carbon budget’ and emitting no more than around 800 gigatonnes of CO2 in total after 2017.

This paper analyzes the observed highest temperatures that occur every year at nearly 9000 stations, and how they are changing over time and especially over the past 50 and 30 years. This research found these short-term heatwaves to be increasing in most places, especially Eurasia and Australia, and also in megacities.

Local and global climate change increases the ambient temperature of cities by several degrees with important consequences on energy consumption, health and the economy. Advanced urban mitigation technologies contribute to decrease the ambient temperature and counterbalance the impact of urban heat islands.

This research reports on an experiment on two small-scale metal roofs in Sydney and Rio de Janeiro to assess the thermal performance of portable small-scale modules. The findings are that green roof retrofitting could lower the cooling energy demand considerably.
