Hammarby Sjöstad

Hammarby Sjöstad is the first eco city district in Stockholm. It is a 'town around a lake' where the planning work begun in 1980s with an opportunity to expand the inner city of Stockholm. It is one of Stockholm's biggest urban development project and it focuses on water and eco-friendly solutions. As a part of the ambition to create an eco-friendly city district, investments in e.g. green spaces, walkways and several large parks. have been made. Furthermore, the Hammarby Model is the eco-cycle which describes environmental solutions used for energy, waste and water and sewage. (Ref. 1 and 2)

Urban setting

  • External building greens
    • Green roofs
  • Parks and (semi)natural urban green areas
    • Large urban park or forest
    • Pocket parks / neighbourhood green spaces
    • Green corridor
  • Green areas for water management
    • Sustainable urban drainage systems

Key challenges

  • Climate action for adaptation, resilience and mitigation (SDG 13)
  • Environmental quality, including air quality and waste management
  • Green space, habitats and biodiversity (SDG 15)
  • Sustainable consumption and production (SDG 12)
  • Water management (SDG 6)

Main beneficiaries

  • Local government/Municipality
  • Public sector institution (e.g. school or hospital)
  • Citizens or community groups
Project objectives
“The goal of the entire environmental programme is to halve the total environmental impact in comparison with an area built in the early 1990s.” The goal for e.g. land usage include: “Sanitary redevelopment, reuse and transformation of old brownfield sites into attractive residential areas with beautiful parks and green public spaces.” Furthermore, objectives of the project include “Development of undeveloped green public spaces shall be compensated for in the form of biotopes that benefit the biological diversity in the immediate area, and natural areas of particular value shall be protected from development.” Also, green roofs are used (as a part of the local storm water treatment) to collect, delay and evaporate rainwater. Also, the small and dense sedum plants form living green areas in the cityscape. Other objectives regarding waste, and water and sewage are also included in the Hammarby Model. (Ref. 4 )
Implementation activities
“Hammarby Sjöstad has its own eco-cycle, the Hammarby Model, which describes the environmental solutions used for energy, waste, and water & sewage.” Furthermore “the Hammarby Sjöstad project office employed a new methodology whereby officials from the relevant administrations and authorities formed a unified management team.” Also, investments have been made in green public spaces (with maintenance plans for the oak forest, a reed park with wooden jetties, a broad avenue, and several large parks) in order to adapt the area to an environmentally friendly one. As mentioned, green roofs have been created (part of local storm water treatment, and forming living green areas). (Ref. 1 and 4).

Details on the roles of the organisations involved in the project
“All relevant administrations and authorities jointly planned the construction of the new city district. The municipality encouraged the builders (developers) to find their own solutions within the common frameworks, including eco-cycling, low energy consumption and energy production. The city then collaborated with developers and companies responsible for waste, energy, water and sewage and implemented the plan for the area.” (Ref. 5). “The City’s administrators and companies, municipal and private developers, the contractors and consultants are jointly responsible for realizing the objectives. Together, they form the group of actors or stakeholders of the development of Hammarby Sjostad.” Note that there is a "high degree of local authority leadership" due to "the fact that the City has acquired the majority of land in Hammarby Sjöstad.” (Ref. 6).

“The development program for Hammarby Sjöstad is guided by well-defined environmental objectives which were drafted by the City of Stockholm. The environmental program was included in the Stockholm application for the LIP (Local Investment Program) as an appendix.” (Ref. 6)
Expected impacts
  • Climate action for adaptation, resilience and mitigation (SDG 13)
  • Economic development and decent employment (SDG 8)
  • Environmental quality, including air quality and waste management
  • Inclusive and effective governance (SDG 16)
  • Social justice, cohesion and equity (SDG 10)
  • Water management (SDG 6)
Details on impacts and indicators used "Once fully built, Hammarby Sjöstad will have 11 ,000 residential units for just over 25,000 people and a total of about 35,000 people will live and work in the area." (Ref. 4) The project not only focused on the design aspect, but also recognised the need to influence how residents use places. The Hammarby Model achieved this through the creation of an environmental centre that promotes understanding of how residents can help to achieve the city’s environmental aspirations. (Ref. 10)
