As the highest-performing city in the 2022 Sustainable Cities Index universe, Stockholm is a leader in urban sustainability. It has the lowest Scope 1 GHG emissions per capita in Europe, so it’s no surprise that the Swedish capital has some of the best air quality of European cities. Both residents and visitors enjoy Stockholm's wealth of open space, such as Djurgården and Ivar Los Park. Stockholmers also have the lowest number of vehicles per household of European cities in the 2022 index universe and opt for more sustainable transport modes.
