About the region

Smart City Sweden East consists of four counties: Stockholm, Uppsala, Södermanland and Sweden’s largest island: Gotland. The region offers a long tradition of cooperation between business and academia, which has contributed to a high level of innovation and a favorable business climate.

Building smart cities require the public sector to be integrated to a large extent, which can be seen in examples in districts such as Hammarby Sjöstad and Stockholm Royal Seaport, where there has been a high focus on climate, environment and energy issues.

A wide range of platforms and corporate networks promote innovation and development in the region. One successful example is the Urban ICT Arena in Kista in the north of Stockholm, one of the world’s leading business clusters for innovation in digitalisation.

Stockholm has one of the world’s largest and most complicated district heating systems with a large number of actors who together produce and distribute district heating & cooling and electricity from hundreds of production units to millions of people. The production has the world’s largest heat pump plant, innovative energy storage, and waste incineration to recover energy from residual products from society and forestry, which contributes to a well-functioning waste management system. Uppsala and Gotland also have well-developed district heating networks with a very small proportion of fossil fuels.

Water and wastewater treatment are key functions in a well-functioning city, a service that often goes unnoticed as long as it performs as planned. Uppland, Södermanland and Gotland all have different challenges with water quality and water supply that have been solved in different ways. In Uppsala, the regional capital of Uppland, water from the passing river Fyrisån is purified through a ridge due to groundwater scarcity. At Hammarby Sjöstadsverk in Stockholm, unique research is conducted on membrane technology for more efficient wastewater treatment, which will make Henriksdal’s wastewater treatment plant one of the largest in the world to use membrane technology. On Gotland, the testbed Storsudret is testing new solutions in drinking water purification.

Social sustainability is key in urban development projects and by initiating dialogue and involvement during construction and renovation processes, the likelihood of a successful project increases significantly. Smart City Sweden East offers examples of social sustainability, such as Fryshuset, an organization that works to support and include young people in the community.

Best practice in the region

#BELOVEDCITY- Collaboration for a better city

Älskade stad (Beloved city) is a unique collaboration concept to save vehicle movements in the city centre and to inspire others to help increase the pace of sustainable Environmental initiatives for a vibrant city.

Stockholm Public Transport – The journey to sustainable public transport

Stockholm public transport (SL) is on a journey to become the most sustainable public transport provider in the world. Achieving a low environmental impact has been a priority for a long time. Today, the SL public transport system is operated on fossil-free fuels and energy from renewable sources.

Let the nature do the work – Stockholm Royal Seaport

Stockholm Royal Seaport, one of the world’s biggest urban planning projects, has developed an integrated stormwater system that purifies and delays storm- and meltwater before it is released into the sea. The system connects green roofs and rooftop gardens with ponds, open storm drain water and surface water drain and urban greenery.

KTH Live-In Lab – Testbeds for Accelerated Innovation

KTH Live-In Lab offers something as unique as a full-scale test beds, ranging from apartments, education building, hotel, changeable interior design and infrastructure, database for user and property data, and a very valuable collaboration platform.

Urban ICT Arena: Testbeds for digitalisation in an urban environment

Urban ICT Arena is a co-creation arena in Kista Science City, one of the world’s leading ICT-clusters, that believes in cooperation as crucial for meeting the goals set out in Agenda 2030. Urban ICT Arena provides tools for ICT companies and the public sector to overcome tomorrow’s challenges – today.


IntegrCity aims at developing and implementing a decision-support platform focusing on planning and designing integrated energy networks and further infrastructure developments. While city planners and energy companies can take advantage of the platform while planning energy supply infrastructure, the projects have also tested different energy supply and energy storage solutions both in Sweden and in Switzerland.

District heating and cooling – A more sustainable energy production

With a water-filled rock chamber beneath Kungsholmen in Stockholm, the energy company Stockholm Exergi has been able to substantially increase capacity in the city’s network for district cooling. The ordinary cooling plants in buildings can be phased out, and both high electricity needs and the risk of leakage of ozone-depleting substances will decrease along with them.

Biogas Xpose: sustainable biogas production through innovative technologies

BIOGAS XPOSE demonstrates how a region with a high demand for biomethane (BM) can increase the production of BM as a renewable vehicle fuel in an economically and environmentally viable fashion by maximizing regional waste as the resource. The project is reducing the total emissions of carbon dioxide with 334 600 tonnes by sustainable production of BM that replaces fossil fuels in the transportation sector. The project ended in 2018.

Extended Producer Responsibility in Sweden: Towards better waste management

Extended Producer responsibility (EPR) is a governmental policy and a Swedish law that aims to better waste management and collection. The Swedish system shifts the waste management cost or physical collection fully from local governments to producers. The policy applies to different goods such as packaging, newsprint, electronic products, batteries, tires, end-of-life vehicles, pharmaceutical waste, stray radioactive products and radioactive sources.

Help from the larvae: Turning food waste into animal feed

How can larvae help reduce food waste and at the same time reduce the risks of spreading diseases? In Sweden, researchers and experts in waste management are working together to turn food waste into animal protein feed.
