Stockholm's air quality is generally good, with little to no risk from air pollution
The city has set ambitious goals for itself, aiming to be climate-positive by 2030 and completely fossil-free by 2040. It is also home to renowned environmental research institutions like the Stockholm Environment Institute and the Stockholm Resilience Centre.
Stockholm's public transport system is impressive, with around 850,000 people using it daily. The entire underground network runs on green electricity, and since 2017, all buses have been powered by renewable fuels. The city also has an "eco-quarter," Stockholm Royal Seaport, which is building thousands of eco-friendly homes and promoting sustainable innovations.
While the city's air quality is mostly good, there are some areas of concern. The lakes in central Stockholm are affected by pollution from settlements, traffic, and industry. Levels of pollutants like cadmium, copper, mercury, and lead in these lakes are far above average. However, efforts to reduce the use of these substances have shown positive results in decreasing their levels in the lake sediments.
Overall, Stockholm is a leader in sustainability and environmental initiatives, and its air quality is considered safe for its residents, who are encouraged to enjoy outdoor activities freely.

The city's water supply is purified, but some lakes have high pollution levels
Stockholm, Sweden's capital, is known for its commitment to environmental sustainability and climate change mitigation. The city has made significant strides in reducing its environmental impact and promoting sustainable practices. However, like many urban areas, Stockholm faces challenges in maintaining water quality in its lakes due to pollution from various sources.
The city's water supply primarily comes from Lake Mälaren, which is purified at plants in Norsborg and Lovön, producing 350,000 cubic meters of potable water daily. This ensures that Stockholm residents have access to clean drinking water. However, the purification process also addresses the issue of sewage pollution, as the plants in Bromma, Henriksdal, and Loudden filter 400,000 cubic meters of sewage daily before discharging it into the Baltic Sea. This treated sewage water contains pollutants such as nitrogen and phosphorus, which can be detrimental to the marine environment if not properly managed.
While Stockholm's water supply is effectively purified, some lakes within the city exhibit high levels of pollution. Central bays, such as Klara sjö, Årstaviken, Ulvsundasjön, Riddarfjärden, and Hammarby Sjö, are particularly affected by pollution from settlements, traffic, and industry. Metals and organic compounds, including cadmium, copper, mercury, and lead, have been found in these lakes, especially on the western side of the city. The reduction in the number of lakes and watercourses in Stockholm over time can also be attributed to lake reclamation for settlements and health reasons, in addition to post-glacial rebound.
The presence of these pollutants in the lakes poses a risk to both the aquatic ecosystem and human health. Stockholm has implemented initiatives to address this issue, such as the Stockholm Convention, a global treaty aimed at phasing out persistent organic pollutants. Additionally, the city has adopted an environment programme for 2030, with the goal of becoming climate-positive by that year. This includes reducing emissions and increasing carbon sequestration, with the ultimate target of a completely fossil-free city by 2040.
Despite the challenges posed by pollution in some of its lakes, Stockholm is committed to environmental sustainability and innovation. The city has been recognised for its efforts, ranking highly in various sustainability and innovation indexes. With its focus on reducing emissions, promoting renewable energy, and developing eco-friendly urban projects, Stockholm serves as an example of a city striving for a sustainable future.

Stockholm's transport system is largely fossil-fuel-free, with green electricity and renewable fuels
Stockholm has been working strategically for decades to reduce the city's impact on the environment, with climate and environmental sustainability being integral to all operations and policy documents. The city's transport system is largely fossil-fuel-free, with an emphasis on green electricity and renewable fuels. Around 850,000 people use public transport on a normal day in Stockholm, and the entire underground system runs on green electricity. Since 2017, all buses have been fuelled by renewable energy sources, achieving the target set for 2025 eight years early.
Stockholm's commitment to sustainability is further demonstrated by the 'eco-quarter' of Norra Djurgårdsstaden, where an old gasworks is being transformed into thousands of eco-friendly homes. This development includes biogas produced from food waste and the provision of electric car chargers, with plans for a new tram line. Additionally, Stockholm Royal Seaport is piloting a smart energy grid in collaboration with energy companies, universities, and homebuilders.
The city has also implemented measures to address water pollution. Stockholm's water supply comes from Lake Mälaren, which is purified at plants in Norsborg and Lovön, producing 350,000 cubic metres of water per day. Sewage is filtered at three plants, removing pollutants such as nitrogen and phosphorus, before being discharged into the Baltic Sea.
Stockholm's efforts in sustainability and environmental protection have gained recognition, with the city being named the first European Green Capital in 2010. The city has also performed well in various rankings related to sustainability and innovation, including the Global Cleantech Innovation Index, the Global Innovation Index, and the Global Sustainable Competitiveness Index.
Looking ahead, Stockholm has set ambitious goals for the future. By 2030, the city aims to be completely fossil-free, with a focus on reduced emissions and increased carbon sequestration. These initiatives contribute to Sweden's broader goal of having a fossil-free transport sector. Stockholm's progress in reducing pollution and its commitment to sustainability make it a model for other cities and countries to emulate.

Stockholm's environmental initiatives include reducing emissions and increasing carbon sequestration
Stockholm, Sweden's capital, has been a leading environmental city for decades. The city has made climate and environmental sustainability an integral element of all its operations and policy documents. Stockholm has been strategically working to reduce its impact on the environment for years, and in 2010, it became the first European Green Capital. The city has unveiled an ambitious Climate Action Plan for 2030, with 150 specific measures designed to rapidly reduce emissions and ensure an inclusive transition.
The Climate Action Plan 2030 is built on the foundation of the Environment Programme 2030, which sets goals for air quality, green spaces, biodiversity, sustainable consumption, and climate mitigation. Stockholm aims to be climate-positive by 2030 through reduced emissions and increased carbon sequestration. The city has implemented a carbon emissions budget to limit emissions to nine million tonnes of CO₂-equivalent between 2024 and 2040. This "climate compass" will guide decisions and help measure the impact of initiatives.
Stockholm's environmental initiatives to reduce emissions include phasing out fossil fuels and investing in renewable energy solutions and carbon capture technologies. The city is working towards a fossil fuel-independent vehicle fleet by 2030, with projects like CleanTruck already reducing carbon dioxide emissions. Stockholm also encourages the use of public transport, bicycles, and clean vehicles, as well as the expansion of walking and cycling infrastructure, to reduce private car dependence.
Additionally, Stockholm is integrating circular economy principles into planning, construction, and land use, prioritizing green infrastructure and biodiversity. The city communicates with its residents to increase knowledge about their climate impact and provide tools to reduce it. Stockholm stands behind the Global Green New Deal initiative, which aims to bring cities together to combat climate change and deliver emission reductions in line with the 1.5-degree goal.
