Together, we will build the world’s best city – a green and vibrant capital that cares for both people and nature. In Oslo, it should always pay off to live environmentally friendly.
We will make climate-friendly travels easier, use energy in smarter ways, and develop the city with green and blue structures that connect nature and urban life. Oslo is leading the way towards a climate-resilient zero-emission society. The Climate Budget is the city of Oslo’s governance tool for achieving Oslo’s climate goals.
The Climate Budget presents measures to be implemented during the 2026–2029 economic planning period. Responsibility for implementation is assigned to municipal entities, which report annually, except for direct emissions, which are reported alongside the municipality’s financial reporting. The Climate Budget consists of four chapters that correspond to Oslo’s five climate goals. Each part specifies which measures are to be implemented in the 2026–2029 economic planning period to help reach Oslo’s climate targets towards 2030. It also presents new budget allocations for climate initiatives.
In addition, the Climate Budget presents identified measures that could strengthen Oslo’s climate efforts if adopted in later climate budgets. These are not currently proposed for implementation but illustrate possible future measures that could help achieve higher emission-reduction results.
More detailed information about the Climate Budget’s methodology can be found in Attachment to the Climate Budget 2026.
Key achievements in 2025
Final investment decision for carbon capture at the waste-to-energy plant at Klemetsrud was secured in January 2025. Construction will continue over the next few years, with operations scheduled to start in the third quarter of 2029. This plant is currently Oslo’s largest single source of emissions, which will be almost entirely eliminated (approximately 90% ) once full operation begins.
Municipalities now have clear legal authority to require zero-emission construction sites from both private and state actors, something Oslo has long advocated. Based on this legal authority, the City Government issued a public consultation in September 2025 on a local regulation proposing that large construction sites must gradually adopt zero-emission or biogas-powered machinery leading up to 2030. The local regulation must be adopted by the City Council.
Further emission cuts are expected from commercial transport, both because Oslo is closer to establishing a zero-emission zone and because zero-emission vans may soon gain access to bus lanes. Both initiatives have been long-term targets for the City Government, though final approval depends on national authorities.
Oslo is a Zero-Emission City in 2030
Direct emissions are emissions that occur within the municipality’s geographical boundaries, so called Scope 1 emissions. By 2030, Oslo aim to reduce its direct emissions by 95% compared with 2009 levels.
Greenhouse gas emissions in Oslo were reduced by 30% from 2009 to 2023, according to the latest greenhouse gas emissions inventory from the Norwegian Environment Agency. The largest contributors to these emissions are the shift to electric vehicles, the use of biofuels, and the transition from oil-fired heating to zero-emission heating. The emission reduction since 2009 is probably underestimated, partly because the effects of Oslo’s measures targeting road traffic and other mobile combustion are not adequately captured in the Norwegian Environment Agency’s greenhouse gas emissions inventory.
Adopted Measures
With the adopted measures in this Climate Budget, Oslo is estimated to reduce its emissions by 70% in 2030. The largest measure is the implementation of carbon capture at Klemetsrud.
The adopted measures in this Climate Budget are estimated to reduce greenhouse gas emissions within Oslo’s boundaries by 75,600 tons of CO₂ equivalents in 2026 and 206,100 tons of CO₂ equivalents in 2029.
The table below presents the adopted measures in the Climate Budget 2026. Here, you can also filter by the municipal entities responsible for the individual measures.

Identified Measures
The table below shows potential new measures that could be implemented to reduce direct emissions by up to 81% in 2030. The identified measures have not been politically decided at either the local or national level, and some require new national clarifications, new legal authorizations, or similar. The measures are not necessarily fully assessed, and their final design will need further evaluation.
Identified measures to reduce direct emissions
| Sector | Identified measures | Effect 2030, isolated (tons CO2e) |
|---|---|---|
| Overarching measures | CO₂ tax equivalent to NOK 2,400 per ton in 2030: The estimated effect assumes that the Norwegian Parliament does not offset the tax increase by easing other measures, such as reducing other fuel taxes. The increase will be followed up annually and depends on national authorities. | 6 000 - 11 000 |
| Waste incineration and energy supply | Carbon capture from household waste from Oslo municipality: A procurement process for such incineration has been initiated, but a final decision will depend, among other things, on the offers received. | 40 000 - 50 000 |
| Phasing out fossil materials at Hafslund Celsio’s waste incineration plant at Haraldrud. | 20 000 - 30 000 | |
| Increased sorting of plastic from household waste: A new waste regulation requires 60% sorting of plastic suitable for material recycling by 2030. REG are assessing how the municipality can increase the sorting of plastic from household waste. | 15 000 - 22 000 | |
| Increased collection, resale, and recycling of textiles: Greater collection can help reduce direct emissions by avoiding incineration. | 2 000 - 4 000 | |
| 100% zero-emission district heating: In periods of high electricity prices or low temperatures, some fossil gas is still used. | 6 000 - 9 000 | |
| Pricing of emissions from waste incineration and new incentives for carbon removal: The government has announced an increase in the waste incineration tax to a general level of NOK 2,400 per ton by 2030. The government is also considering new measures, such as reverse auctions, to support carbon capture at waste incineration plants. | Not calculated | |
| Waste and wastewater | Optimisation of the operating regime of the gas facility at Grønmo: This includes the ability to flare the gas during periods of low negative pressure in the landfill, which may increase gas collection from the landfill and thereby reduce emissions. This requires approval from the County Governor. | Not calculated |
| Improvement of the top cover at Rommen landfill: The landfill at Rommen has an old top cover that is not gas-tight. A new top cover could reduce leaks and increase the collection of landfill gas. | Not calculated | |
| Sealing measures to reduce the infiltration of clean stormwater and groundwater into the landfill at Grønmo: Less water infiltration may increase the collection of methane from the landfill. | Not calculated | |
| Improvement of the drainage system in the gas facility in the oldest landfill areas at Grønmo: This could increase gas collection from the landfill. There are periodic challenges with water levels in the landfill and drainage, especially during winter and snowmelt periods. | Not calculated | |
| Road traffic | Increase of the national biofuel blending mandate to 33% in road traffic by 2030: This was announced in the 2025 National Budget. The government sets a new level every other year. The proposed increase from 2026 is under consultation in spring 2025. | 6 000 – 11 000 |
| Double toll rate for new fossil-fuel passenger cars during 2026: Adopted in the revised Oslopakke 3-agreement in spring 2024. The measure requires that national authorities allow for this in the toll proposition to be presented in 2026. | 2 000 – 3 000 | |
| Double toll rate for new fossil-fuel vans: This measure requires national authorities to allow for the creation of a new toll rate category, for example in the toll proposition to be presented in 2026. The Oslopakke 3-agreement also states that further incentives to shift the van fleet from fossil fuels to zero emissions should be considered during the agreement period. | 2 000 – 5 000 | |
| Zero-emission zone for vans and heavy-duty vehicles within Ring 2 (along the inner toll cordon): This requires legal authority to be granted by national authorities. On 1 August 2025, the Norwegian Public Roads Administration submitted a proposal to amend the law and regulations on zero-emission zones. | 8000 - 14 000 | |
| Zero-emission zone for passenger cars within Ring 2 (along the inner toll cordon): Requires legal authority, see above. | 500 -1 000 | |
| Introduce parking fees and reallocate parking spaces at municipal workplaces: This can be implemented through a local decision. | 700 -1 200 | |
| Expand and offer cheaper charging for vans: This can be done by establishing overnight charging at municipal parking facilities (scaling up the pilot project mentioned in the table of adopted measures) and removing parking fees for vans that charge at municipal locations. | Not calculated | |
| Strengthened national measures for zero-emission heavy-duty vehicles: These are intended to help achieve the national target of 100% zero-emission or biogas in new vehicle sales by 2030. According to the government, new measures will be considered if the transition progresses slowly. | 5 000 – 10 000 | |
| Requirements in permits for buses operating in Oslo (beyond Ruter): In 2023, the Norwegian Parliament requested that the Government propose a legislative amendment to allow zero-emission requirements for all permit-based operations. No changes have been introduced so far. | 2 000 – 4 000 | |
| Doubling of public parking fees for fossil-fuel vehicles (excluding residential parking): This can be implemented through a local decision and gradually increased toward a doubling by 2030. The calculation shows the effect of a doubling within Ring 3. | 3 000 – 6 000 | |
| Require private actors to charge for parking: This could apply to workplaces, shopping centres, etc. Requires national legal authority. | Not calculated | |
| Facilitate the transition from passenger cars to electric motorcycles: By reallocating parking spaces, providing information, and introducing differentiated parking fees for electric and fossil motorcycles. Can be implemented through a local decision. | Not calculated | |
| Introduce a new pricing model for charging at municipal charging stations to encourage increased utilisation throughout the day. | Not calculated | |
| Expand the residential parking scheme in the outer city: This will help reduce non-resident parking in outer city areas by introducing fees for unregulated parking for those without a residential parking permit. | Not calculated | |
| Other mobile combustion | Require all construction sites to be zero-emission by 2030: Legal authority for municipalities to set climate requirements for construction sites has been adopted. Oslo municipality has submitted a local regulation for external consultation. This measure will replace measure 15 in the table of adopted measures once it is adopted. | 5 000 - 6 500 |
| Increase of the national blending mandate for advanced biofuels to 28% for non-road machinery: The government will determine the specific increase every other year. The next increase from 2026 was under consultation in spring 2025. | 8 500 - 12 000 | |

| Environmental differentiation of port fees for ships using renewable fuel. | Not calculated | |
| Access to quays and other areas for ships using renewable fuel. | Not calculated | |
| Heating | National ban on the use of gas for permanent heating: The government is following up the Parliament's decision and is assessing a ban on fossil gas for permanent heating, with the aim of implementation from 2028. | 7 000 - 11 000 |
Towards Sustainable Consumption
In Oslo, we primarily consume goods produced outside the municipality, meaning that the majority of our climate footprint comes from emissions that occur elsewhere (indirect emissions). This also applies to the city of Oslo as an organisation, which provides a wide range of public services to the city’s residents.
Reducing the climate footprint of the city of Oslo’s own operations is therefore highly important. At the same time, this can help promote a more circular economy in the city and the wider region, through the municipality’s direct contracts and cooperation with the business sector.
Adopted Measures
In 2026, Oslo municipality will assess a new location and business model for a reuse centre for construction materials, as part of Oslo’s circular infrastructure. The municipality will also consider the possibility of centralised ownership and management of municipal PCs. The aim is to extend their service life, which could result in cost savings of NOK 45.5 million and annual emission reductions of around 1,700 tons CO₂ equivalent.
The table below presents the adopted measures in the Climate Budget 2026. Here, you can also filter by the municipal entities responsible for the individual measures.
Adopted measures for a more circular economy and reduction of emissions outside Oslo’s boundaries (indirect emissions)

Identified Measures
The table below shows potential new measures that could be implemented in Oslo to support a more circular economy and further reduce indirect emissions.
The identified measures have not been politically decided at either the local or national level, and some require new national clarifications, new legal authorizations, or similar. The measures are not necessarily fully assessed, and their final design will need further evaluation.
Among the identified measures, setting requirements to reduce emissions from materials will have the greatest impact on emission reductions. A large share of these reductions will also support a more circular economy in the construction sector, through reduced material use, reuse, increased renovation, and material recycling.
Identified measures for a more circular economy and reduced indirect emissions
| Sector | Identified measures |
|---|---|
| Construction | |
| Set requirements for gradually reduced emissions from materials for all developers: This could result in annual emission reductions in the range of 100,000–150,000 tons of CO₂ equivalents by 2030. | |
| Set standard requirements for materials in the municipality’s construction projects: A municipal working group is developing a proposal for new standard requirements to be considered by the City Government. | |
| Require reuse assessments in municipal construction projects involving the removal of existing infrastructure, such as sports facilities or playgrounds, where the estimated waste volume exceeds 10 tons. | |
| Consumption and retail | |
| Establish a comprehensive solution for the reuse of furniture and furnishings in municipal operations: UKE is currently assessing how this can be structured. The solution should help reduce costs and emissions, while meeting storage and transport needs in a user-friendly and cost-effective way. | |
| Reduce the use of single-use plastic cups and food packaging at Oslo’s events and food service establishments: Consider the use of a local regulation, a municipal environmental fee, and subsidies for a shared environmental discount. | |
| Adopt a new goal for reduced meat consumption in municipal operations by 2030: The current goal expires in 2025. | |
| Adopt a guideline requiring all entities, when renegotiating lease agreements or in collaboration with other tenants, to promote measures for sustainable, healthy, and more plant-based food in canteens. | |
| Strengthening of extended producer responsibility schemes: Contributes to ensuring that producers and importers of various products take responsibility for packaging and products throughout their entire life cycle, including when they become waste. This can create incentives to extend product lifespans and reduce volumes. As of 1 July 2025, the Ministry of Climate and Environment has amended Chapter 6 of the Waste Regulations concerning extended producer responsibility for plastics. Oslo municipality will negotiate a new agreement with the producer responsibility organization to have a greater share of the costs for collection and handling of plastic packaging covered. | |
| Travels and mobility | |
| Increase the number of parking spaces reserved for electric shared cars on municipal property in areas close to the city center. | |
| Make the municipality’s own goods deliveries more efficient by, among other things, increasing centralised purchasing, reducing the number of delivery days, avoiding partial deliveries, unnecessary express deliveries or small orders, and increasing consolidated deliveries of goods transported to the same area. In addition, deliveries could be scheduled at times of day that allow for more efficient use of vehicles and road capacity. | |
| Introduce common guidelines for business travel in municipal operations: Flights should be minimised where alternative travel methods are available that are not disproportionately expensive or time-consuming. | |
An Energy System Adapted to the Zero-Emission City
A robust, flexible, and zero-emission energy system is a prerequisite for Oslo to achieve its goal of becoming a zero-emission city. Since 2009, total energy consumption in Oslo has decreased by 10%. This is largely due to the electrification of the passenger car fleet (electric motors have higher efficiency than combustion engines, thereby reducing energy consumption per vehicle), the phasing out of oil for heating, and more energy-efficient buildings.
Adopted Measures
To achieve the goal of a 95% emission reduction, we must ensure sufficient capacity in the power grid. The future total power demand for the electrification of heavy transport and the construction sector is estimated at around 100 MW. Adopted measures in the Climate Budget 2026 are estimated to make 11 MW of capacity available.
The table below presents the adopted measures in the Climate Budget 2026. Here, you can also filter by the municipal entities responsible for the individual measures.

Identified Measures
Although the goal for reduced energy consumption is within reach, additional measures are needed to ensure that Oslo has sufficient energy and capacity to achieve the climate goal of 95% emission reduction. The table below provides an overview of identified measures that could contribute to this.
The identified measures have not been politically decided at either the local or national level, and some require new national clarifications, new legal authorizations, or similar. The measures are not necessarily fully assessed, and their final design will need further evaluation.
The most important identified measure is to require local energy production and shared energy solutions in zoning plans. This will facilitate the development of effective energy systems that help reduce energy demand and peak loads, while also increasing local energy production.
Identified measures for energy
| Sector | Identified measures |
|---|---|
| Overarching measures | Require local energy production and shared energy solutions: The Norwegian Building Authority has, among other things, submitted a proposal for a potential new provision on solar energy for commercial buildings over 500 m² in the Building Technical Regulations (TEK17) for public consultation, with a deadline of 26 September 2025. |
| Changes to the national electricity support scheme and the “Norway Price” scheme: The “Norway Price” scheme, planned for implementation on 1 October, along with the existing electricity support scheme, increases the payback time for investments in energy efficiency. These schemes should be designed to better incentivise energy efficiency measures and energy flexibility. | |
| Energy efficiency | Differentiate property tax based on energy rating for commercial buildings: This would give private actors an incentive to upgrade their buildings to a higher energy class. The municipality currently does not have the legal authority to implement this. The measure would require legislative changes. |
| Set minimum energy rating requirements in the municipality’s standard lease agreements for commercial premises: By requiring an energy rating in lease agreements and promoting energy efficiency measures to property owners, the municipality can pressure private actors to upgrade their existing buildings. The municipality is currently assessing the need and feasibility of setting more ambitious energy requirements in its standard lease agreements for commercial spaces. | |
| Energy flexibility | Incentives for conversion to waterborne heating systems in buildings: This could target large housing cooperatives, condominiums, and commercial buildings to encourage greater use of thermal heating, such as district heating. This would help relieve pressure on the electricity grid. |
| Establish pilot areas for low-temperature district heating networks: This would enable increased use of surplus heat and more energy-efficient district heating solutions in new or fully renovated development areas. | |
| Energy production | Establish local power production on grey areas: Oslobygg is working to identify grey areas on its properties. Suitable municipal areas could also be made available for solar power production by private developers through competitive tenders. |
| Map the potential for solar energy production when selling municipal plots and consider requiring local energy production. |
Oslo is a Climate-Resilient City with Increased Carbon Uptake and Storage
Oslo aims to become a climate-resilient city, meaning that the city’s ability to withstand climate change will be strengthened by 2030, and it will be developed to cope with the changes expected by 2100. Oslo must be able to endure and manage a warmer and wetter climate.
To become a climate-resilient city, we must stay ahead of climate change. Oslo has made significant progress in managing stormwater, which must remain a high priority moving forward. Work is now underway to ensure Oslo can handle the broader range of risks posed by climate change. In addition to climate-resilient infrastructure and climate-adapted emergency preparedness, a climate-resilient and diverse natural environment plays a central role in enabling the city to withstand climate change.
Climate-resilient forests and other vegetation absorb and store carbon. Oslo’s ambitions for low-impact logging are important in this context. It is also crucial to limit the development of carbon-rich areas, which are found in the forest areas (marka), built-up zones, and the fjord. Increased knowledge about these carbon stores is essential.
Adopted Measures
With the adopted measures in the Climate Budget, efforts to establish a coherent floodway and stormwater retention network will be strengthened, Oslo’s forestry practices can become more nature-friendly, including on forest land not owned by the municipality, and work to make Oslo a land-use neutral municipality will be initiated.
Together, this will strengthen Oslo’s efforts to become a climate-resilient city that safeguards natural carbon stocks.
The table below presents the adopted measures in the Climate Budget 2026. Here, you can also filter by the municipal entities responsible for the individual measures.

Identified Measures
The table below shows identified measures that could be implemented to strengthen efforts on climate adaptation and natural carbon storage in Oslo. The identified measures have not been politically decided at either the local or national level, and some require new national clarifications, new legal authorizations, or similar. The measures are not necessarily fully assessed, and their final design will need further evaluation.
The most important identified measures are improved consideration of climate adaptation in land-use planning and the introduction of a requirement for land-use neutrality.
Identified measures for climate adaptation and increased natural carbon storage
| Sector | Identified measures |
|---|---|
| Flood and stormwater | Establish a reception mechanism for emergency assistance during extreme weather: Norway participates in the EU Civil Protection Mechanism and can receive assistance from other countries during extreme events such as floods and wildfires. However, this requires a local reception system within the municipality. |
| Develop guidance for assessing climate adaptation considerations in planning cases at the district level: City districts need improved guidance to account for current and future climate risks in planning processes. | |
| Improve integration of climate adaptation in land-use planning: There is a need for better risk and vulnerability analyses (ROS analyses) in construction projects, greater consideration of watercourses in land-use planning, and more suitable areas for snow management. | |
| Increase frequency of sand trap emptying to improve stormwater treatment from streets and pipes: A review by Bymiljøetaten shows that twice as many sand traps need to be emptied annually compared to current levels. | |
| Consider using new legal authority to require stormwater measures on existing buildings. | |
| Wildfire prevention | Develop an action plan for wildfire prevention in Marka: The municipality’s work to promote site-adapted, multi-aged forestry helps prevent wildfires, but a systematic analysis of wildfire vulnerability and other potential measures—such as vegetation clearing near residential areas or the establishment of firebreaks in Marka—is still needed. |
| Climate-resilient nature | Rezone land to prevent development on valuable natural areas and carbon sinks. |
| Prohibit logging and interventions in old-growth forest and intact peatlands: The Department for Environment and Transport will prepare a proposal for an instruction to the Regional Agricultural Office (RKL) based on expert recommendations from RKL, the Climate Agency (KLI), and the Agency for Urban Environment (BYM), with the aim of having the instruction incorporated into zone plan case processing. | |
| Restrict construction of new agricultural roads: The Department for Environment and Transport (MOS) will prepare a proposal for an instruction to RKL, based on expert recommendations from RKL, KLI, and BYM, with the aim of incorporating it into zone plan cases. |
