Resource efficiency and reduced climate Impact
Many of the challenges facing Stockholm involve the repercussions of global warming. Other challenges are the spread of environmental toxins, linear nutrient flows, and unsustainable energy and water use. Stockholm is expanding largely by transforming former industrial sites requiring remediation and management of environmental liabilities from the past. Efforts are needed to address these challenges.

Since the 1970s, the City of Stockholm has been systematically addressing environmental and climate issues. This work is guided by a city-wide environmental programme and a climate action plan. One of the key goals is to become climate positive by 2030 and fossil-free by 2040. The Chemicals Plan outlines the path towards the long-term goal of a Toxin-Free Stockholm.
Stockholm Royal Seaport is to be a fossil-free part of the city by 2030, with efficient resource use and low environmental and climate impact. Technical supply systems are integrated with closed-loop energy, water, and material systems. All buildings and facilities are planned with high quality and non-toxic materials.
Achievements for 3. Resource efficiency and reduced climate Impact
3.1 Reduce amounts of waste
- To date 29% of the area has been remediated.
- 1,050,000 tons of excavated materials have been reused in Stockholm Royal Seaport, which means that approximately 70,200 round-trip journeys have been avoided.
- The amount of construction waste in new construction varies greatly between the developers; from 25 to 158 kg/m² GFA. The average is 47 kg/m².
- in Stockholm Royal Seaport is 88 kg per person/year 2023.
- Pop-up Reuse has so far been visited by 39,000 people, since its launch in 2017. In 2023, it was visited by approximately 7,400 people, 20,700 items were given new owners, thus 3.1 tonnes have been recycled.
3.2 Resource-efficient water and effluents
- Planning guidelines for sorting sewage systems have been developed within the R&D project MACRO
3.3 Fossil-fuel free energy and transport system
- On average, Norra 2 is 67 kWh/m2 (66 kWh/m2 according to Swedish building code regulations BBR19 and 20) On average, Brofästet is 65 kWh/m2 (54,5 kWh/m2 according to BBR23 and 24)
- During 2023, 644 MWh of solar energy was produced on the roofs of completed phases. Additionally, the generated 235 MWh of solar electricity, and the produced 37 MWh.
- In 2023 residents survey, 29% of households have agreements on eco-labeled energy.
- 33 car parking spaces in the streets have electrical charging (carpooling) and a fast charging station. Additionally, 16% of car parking spaces on development sites are equipped with electrical charging.
- There are currently two filling stations for 100 in Stockholm Royal Seaport.
- 68% of the fuel used for machinery and vehicles in development sites during 2022 has been renewable. From 2024, there will be a requirement for 100% renewable fuels in construction machinery and transport.
3.4 Low climate impact
- Average climate impact (public open spaces): Norra 1: 460 kg CO2e /m2, Västra: 3,130 kg CO2e /m2, Norra 2: 270 kg. CO2e /m2.
- Climate impact from energy use in Norra 2: Total amount is 1,640 tonnes CO2e equivalent to approx. 248 kg CO2e/person.
3.5 Good indoor climates
- 80% of developers meet gold standard for indoor environments.
- The 2023 residents survey shows that 93% of the residents feel that the availability of daylight is generally good or very good, 83% believe that the air quality and 68% that the temperature is very or quite good in their home.
3.6 Sustainable selection of building materials
- All stones have been checked based on ethical requirements.
- 100% of developers and 90% of the City of Stockholm contractors document materials in digital logbooks.
- for wood products was carried out in 2022, and in 2019 the LCC for fall protection and waste bins connected to the vacuum waste collection system was carried out.
