Climate statistics

The City of Oslo has had a remarkable reduction in the direct greenhouse gas emissions over the last years. The goal is to reduce the direct GHG emissions with 41 percent in 2020 and to become a nearly zero-emissions city in 2030.

The greenhouse gas emissions in the city are decreasing

The total amount of direct GHG emissions have been decreasing since 2013. The Norwegian Environment Agency publishes emission statistics anually.

The statistics shows that the direct GHG emissions from road traffic have been reduced by over 15 percent compared to 2009. The change is mostly due to an increased adoption of biofuels, increased share of electric vehicles and a renewed car fleet.

Road traffic is still the sector with the largest share of emissions in Oslo, and in 2018 heavy duty and light vehicles together emitted 47 percent of all the GHGs in the city.

Energy supply is the second largest emissions source, with 21 percent of the emissions in the city. These emissions come from waste incineration plants at Klemetsrud and Haraldrud, which recover the heat to produce district heating.

The climate indicators show a possible continuation of the emission reductions

The emission statistics are published on a yearly basis, with a bit more than one year delay. The municipality of Oslo, through its Climate Agency, collects and publishes climate indicators in order to be able to assess how the GHG emissions will develop until the next update of statistics. The indicators are also used to evaluate how measures and policy instruments influence the emissions. The climate indicators are based on statistics from various organisations in Oslo and are published three times per year in the Climate Barometer reports (in Norwegian), as well as graphically on (in Norwegian).

Emissions from road traffic

The climate barometer shows that more and more registrations for new cars in Oslo are for electric cars. This does not include hybrid cars. New light distribution vehicles are also increasingly electric.

Statistics for vehicles passing through the city’s toll ring show that the share of electric vehicles is increasing. This shows that more and more people are choosing an electric vehicle when they drive in Oslo. This development indicate a potential continuation of the reduction in greenhouse gas emissions from road traffic in Oslo.

Most of the other indicators in the climate barometer indicate either a stable trend or a reduction in GHG emissions from other sectors.

The municipality of Oslo has reduced a large part of its own emissions

The city of Oslo implements measures for reducing GHG emissions from the municipal agencies. Internal reporting show that the total emissions have been reduced by 70 percent in the period 2012 to 2019.

Transport vehicles from the agencies and the use of construction equipment represented the largest share of the emissions in 2019.

The document greenhouse gas emissions from municipal agencies in Oslo (PDF 0,2MB) provides an overview of the development and data per emission sector, between 2012 and 2019. There are a number of uncertainties in the yearly reporting from the municipal agencies in Oslo which are also described in the document.
