As a leader in renewable energy, 100% of Iceland’s electricity is produced from hydropower and geothermal resources. A whopping 90% of Iceland's buildings are heated by utilizing the country’s natural heat sources like geysers and hot springs while the other 10% is heated with electricity. By the year 2040, Iceland’s government has set out to be completely carbon neutral.

Ranked as #1 this year in the Sustainable City index, Oslo boasts over 1,400 km of forest roads and 2,100 km of nature trails. With large amounts of greenery and low carbon emissions, Oslo has been able to achieve the World Health Organization’s (WHO) target air pollution figures of 10-12 µg/m³ since 2019.

The city is hoping to reach net-zero emissions by the year 2050. 

Thanks to the help of financial incentives and building regulations, the city of Basel, Switzerland passed a law in 2002 that would ensure all new and renovated flat roofs are  “green roofs”.Green roofs are defined as contained green space on top of a human-made structure.
