In a recent study, Canberra came out on top with an index score of 427, beating Madrid (403) and Brisbane (382) to claim the title of the most sustainable city in the world.

Canberra has been named the most sustainable city in the world, leading with excellent public transport and air quality, according to a new study by Uswitch.  

The study analysed green spaces throughout each city, along with public transport, air quality and energy sources, giving each an index score out of 600.

Canberra came out on top with an index score of 427, beating Madrid (403) and Brisbane (382) to claim the title of the most sustainable city in the world.

According to the study, Australian cities in general perform well, with excellent solar power bidding farewell to energy options of the past.

Uswitch revealed that 88.6% of Canberra’s transport infrastructure is green; the vast network of public transport contributing to the high score in transportation infrastructure.

Canberra was also found to have low pollution levels, only scoring 13.89 on the pollution index, meaning out of every 100 particles of air 13.89 are polluted.

Other factors that shot Canberra to the top include the use of solar power, wind farms and the connectedness of the city with 94% of residents able to access the internet.

A variety of other ranking factors were considered to compile the report, including crime rates, affordability of property, traffic levels (including commute time, CO2 emission and inefficiencies of traffic system), pollution levels (air, water, and smaller types), use of renewable energy.

Jeddah, Saudi Arabia was scored as the least sustainable city, followed by New Delhi in India and Amman in Jordan.
