Challenges

Stockholm faces a number of challenges, such as a rapidly growing population (+40% by 2030), and how to preserve and develop a sustainable, resilient, low-carbon society, to be fossil fuel free by 2040. As a coastal city, Stockholm must also adapt to rising sea levels.

The challenges for SRS are; to be fossil fuel free; to develop and integrate a livable city district within an industrial brownfield area - with a harbour and energy plant of crucial importance for Stockholm and Sweden; to connect the city district with the rest of the city, enabling walking and biking; to develop tools and methods to increase social sustainability; and to partner with a construction industry resistant to change.

Actions

The main climate goals of the project are to develop a city district that is: 

  • fossil fuel free by 2030 and climate positive (according to CCI standards) by 2030. This will result in a reduction of 36,000 tons of CO2 per annum compared to business-as-usual.
  • climate-adapted to rising temperatures, sea - and groundwater levels as well as increased precipitation. 

The fossil fuel free and climate positive goals are to be achieved through requirements on developers such as extremely energy efficient buildings, use and production of renewables, waste management, traffic and mobility management and resource-efficient production. The climate adaptation goal is achieved through safe ground levels, local stormwater management, and by introducing a Green Space Index that regulates the use of ecosystem services for stormwater management, biodiversity and recreational purposes. 

In terms of energy efficiency, all new buildings must comply with passive house energy requirements. In terms of mobility, measures to promote walking, biking and public transport as main modes of transport must be rolled out; the mode split should include 70% of work-related trips by public transport. In terms of waste management, there is zero waste to landfill target and the automated waste management system reduces energy use by 75-80%. Buildings must allow for a reduction in average water use from 150 litres/person a day to 100 litres/person a day. Developers must install solar PV to cover 10-20% of building electricity need.

Projected Outcomes

The SRS is clearly referenced in the City´s Environmental Program and Climate Plan. Stockholm is developing the next generation of sustainable city districts paving the way for the rest of the city and helping to achieve a fossil fuel free Stockholm by 2040.  Findings from SRS are implemented city-wide and contribute to sustainability all across the city; already, they have influenced policies on energy requirements, green space index, stormwater management, and traffic planning.   

SRS will be a living and integrated city district, built with the human scale in mind. The development will connect the northern and southern part of the Royal National Park and contribute to the area’s biological diversity. Other co-benefits include; cost savings due to lower resource use (energy, transport, waste) over the long term; green growth by creating green jobs in the clean tech sector; a stronger community through the creation of networks, project groups and residents association; and the proximity to and availability of green structures.

Good examples from the SRS are continuously transferred to the City's ordinary development projects. All participating departments are transferring the experience into their projects. 

Lessons from SRS are already applied to other developments in the city and the region and will continue when new solutions are evaluated and demonstrated to be viable.
