A team from the Barcelona Institute for Global Health (ISGlobal), a center supported by the “la Caixa” Foundation, has identified the European cities with the highest and lowest rates of mortality attributable to a lack of green space. The team analyzed more than 1,000 cities in 31 European countries and concluded that up to 43,000 premature deaths could be prevented each year if these cities were to achieve the WHO recommendations regarding residential proximity to green space. The data were published in The Lancet Planetary Health.
