At the beginning of the year, I worked as Casual Research Assistant at Curtin University, creating a draft presentation for the “Sustainable Future Cities” research conducted by Dr. Elizabeth Karol (Dept. of Architecture and Interior Architecture).
The Sustainable Cities Index, uses ‘three pillars of sustainability’ to rank 100 global cities:
1) People (social): looks at quality of life, assessing areas such as health, education and work-life balance.
2) Planet (environmental): examines areas including energy consumption, renewable energy share and green spaces.
3) Profit (economic): looks at environment and economic health of the city.
Sub-pillars include ease of doing business, GDP per capita and connectivity.
Zurich (Switzerland) is the world’s most sustainable city in 2016, thanks to its strong focus on environmentalism (#1 in the world ranking) as well as world-renowned financial institutions (#5), even if scores less well in the social dimension, being affordability and work-life balance the main reason (#27 in the world ranking).
“No one city is balancing all three areas of sustainability, but may do well in two ratings. This indicates the challenge that cities have in balancing all three needs effectively to ensure long-term sustainability.” John Batten (Arcadis Global Cities Director)
It is very interesting to notice that none of the 4 major Australian cities are in the top 10 of the 100 cities indexed globally, with Perth not even considered in the list. Indeed, Canberra is placed #18, Sydney #21, Brisbane #30 and Melbourne #32.
According to Greg Steele (CEO Australia Pacific, Arcadis), the result is mainly due to the following Australian cities characteristics:
– ‘radial’ networks
– less frequent transport options
– people preference to drive
– traditional preference for low-density living, which can inhibit housing affordability, access to services and even work-life balance.
I fully agree when he says that the key for the future is to find a comfortable ‘liveable density’, where transport, waste management and connectivity are easier to improve, increasing the overall quality of life in cities.
What do you think about it? I would love to hearing from you…
