Consumer comparison and switching service Uswitch has done a study that has revealed Canberra to be the most sustainable city across the globe.

The report scores a city out of 600 for its sustainability measures that include energy, transportation infrastructure, affordability, pollution, air quality, Co2 emissions and the percentage of green space accessible in the city.

The nation’s capital garnered a score of 427, due to its superior public transport service, renewable and sustainable energy sources, and recording one of the lowest scores at 13.89 on Uswitch’s pollution index. Canberra depends on solar power and regional wind farms, with 94% of residents connected to high-speed internet also enhancing this high score.

Spanish capital Madrid placed second with a score of 403, with Brisbane claiming third place. The river city scores low on pollution cases at 21.8 percent and an elevated transport infrastructure percentage at 75 percent. A pair of Australian cities in the top three emphasises the commitment to sustainability Australian cities offer, with the usage of solar power a primary motivation for both cities’ high scores.

Wellington, New Zealand, has less pollution than any other place studied, scoring 13.66 on the pollution index, meaning from every 100 particles of air, only 13.66 are polluted. Nairobi, Kenya, garnered the highest score for renewable energy, with 90% of its energy sources sustainable, with most of it originating from hydroelectricity or geothermal energy.

Saudi Arabian port city Jeddah got the lowest score on the Uswitch index, rendering it the least sustainable city in the globe according to the study. With a heavy reliance on fuel and gas, the city encompasses much of Saudi Arabia, with the national economy funded by fossil fuel exports, which encompass the nation’s bank balance but harm its effect on the environment. New Delhi, India, was scored as the second least sustainable city, with Amman in Jordan scoring third lowest.
