  At the beginning of 2010, Stockholm launched the program Professional Study Visits in order to share the city's green best practices. The program provides visitors with the opportunity to learn how to address issues such as waste management, urban planning, carbon dioxide emissions, and sustainable and efficient transportation system, among others.
  
  According to the European Cities Monitor 2010, Stockholm is the best city in terms of freedom from pollution. Surrounded by 219 nature reserves, Stockholm has around 1,000 green spaces, which corresponds to 30% of the city's area. Founded in 1995, the Royal National City Park is the world's first legally protected "national urban park". For a description of the formation process, value assets and implementation of the legal protection of The Royal National Urban Park, see Schantz 2006 The water in Stockholm is so clean that people can dive and fish in the centre of the city. The waters of downtown Stockholm serve as spawning grounds for multiple fish species including trout and salmon, though human intervention is needed to keep populations up. Regarding CO emissions, the government's target is that Stockholm will be CO free before 2050.
