The city has a target of reducing the direct GHG emissions down to a maximum if 766,000 tonnes CO2e in 2020, and to become nearly emission-free in 2030. This means that emissions need to be reduced by 95 percent in 2030, compared to 2009. The city is implementing measures to reduce the emissions, presented in the climate budget 2018 and 2019.
The greenhouse gas emissions in the city continued decreasing
In April 2019 the Norwegian Environment Agency published emission statistics showing that the total GHG emissions in Oslo were about 1.1 million tonnes CO2e in 2017. This represents a reduction of almost 9 percent compared to 2016, and 22 percent from 2009.
The change from 2016 is mostly due to an 11 percent reduction in emissions from road traffic, linked to an increased adoption of biofuels, increased share of electric vehicles and a renewed car fleet.
Road traffic is the sector with the largest share of emissions in Oslo, and in 2017 heavy duty and light vehicles together emitted 583,682 tonnes CO2e, or 54 percent of all the GHG in the city. Energy supply is the second largest emission source, with 270,657 tonnes CO2e, or 25 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. Read more about the emissions in Oslo in 2017 and the developments since 2009 in the document GHG emissions from the city of Oslo (PDF 0,3MB).
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 KlimaOslo.no (in Norwegian).
For emissions from road traffic, the climate barometer show that more and more of the new registrations for cars in Oslo are electric. In the first quarter of 2019 these vehicles made up 65 percent of the registrations, compared to 43 percent in the first quarter of 2018. This does not include hybrid cars.
New light distribution vehicle are also increasingly electric, and now represent 15 percent of the sales in this segment in Oslo. When looking at the total fleet of light distribution vehicles in the city, almost 4 percent are electric. For personal vehicles, the share is 14 percent of the total fleet.
Statistics for vehicles passing through the city’s toll ring show that the share of electric vehicles is increasing, up to 20.8 percent in the first quarter of 2019. This shows that more and more are choosing an electric vehicle when they drive in Oslo.
The total traffic through the toll ring fell after the implementation of time-differentiated and environmentally-differentiated toll rates in fall 2017. The traffic was 3.8 percent lower in 2018 than the year before. 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 with 62 percent in the period 2012-2018. The municipal agencies in Oslo represented 0.4 percent of the total emissions in the city in 2017.
The emissions have however increased by 2 percent between 2017 and 2018. This change is mostly due to an increased use of fuel oil and kerosene for heating, as well as emergency generators. All agencies indicate that they will phase-out oil-fired boilers in 2019.
Transport vehicles from the agencies and the use of construction equipment represent the largest share of the emissions in 2018.
The document provides an overview of the development per emission sector, between 2011 and 2018, with data.
There are a number of uncertainties in the yearly reporting from the municipal agencies in Oslo. The document also describes the most important uncertainty factors for each emission sector.
