Through Climate change, Middle East and Biodiversity

On a per-capita basis, Norway is the world's largest producer, and exporter, of oil and natural gas outside the Middle East. In 2016, 56 new licenses for oil exploration near the Lofoten Islands were issued. However, 98% of Norway's electricity demand is supplied by renewable sources, mostly from hydroelectric power, generated using Norway's extensive freshwater reserves. Emissions are also generated through transportation, although Norway is a world leader in electric vehicles.

Warmer temperatures in Norway are causing permafrost and glaciers to retreat, and leading to shifts in precipitation patterns. Climate change is particularly impacting Norway's Arctic region. Biodiversity and forested areas are experiencing shifts due to the phenomenon, with significant implications for the agriculture and economy of the country. Indigenous Sámi people's practices are being impacted by climate change.

Norway's government have introduced several social and economic policies towards climate change mitigation, including through carbon capture and storage. Norway wants to achieve carbon neutrality by 2030, partly by investing in projects with emissions reduction abroad. It wants to achieve zero emission in the country by 2050. In 2020, Norway pledged to achieve a 50% - 55% reduction in domestic emissions from the level of 1990 by 2030.

Greenhouse gas emissions

Energy consumption

In 2015, Norway's energy supply reached 1.7 million tonnes – a 311.3% increase since 1990 - and their total domestic consumption was 213 terawatt-hours (TWh) in 2015, of which 89 TWh were used by households and services. This was a 2% increase in household consumption, which has been attributed to lower temperatures causing a rise in demand for heating, which also led to a 7% rise in biofuel use from 2014. Due to rising global demand in natural gas and oil, 56 new licences were issued in January 2016 to allow more oil exploration near the Lofoten islands, in addition to the North and Barents seas. This poses a threat to biodiversity and fish stocks in these areas despite numerous promises to improve their environmental ratings and the Paris pledge. On the other hand, 98% of Norway's electricity demand is supplied by renewable energies, 95% of this comes from hydroelectric power. Because of the knowledge that their electricity is supplied by renewable sources and its very low cost as it is produced domestically, consumption in Norway is three times higher than the average European. Electricity consumption equates to approximately 77% of household energy usage in an average detached house.

In 2023, Norway achieved a notable 4.7% reduction in emissions, decreasing from 48.9 million metric tons of CO2 equivalent in the previous year to 46.6 million tons. This progress is part of a continuing trend, with the peak emissions since 1990 recorded in 2007 at 56.5 million tonnes. A significant factor in the recent reduction has been the decreased emissions from car traffic, largely attributed to the increased adoption of electric vehicles (EVs) and the integration of biofuels.

Transportation

The transportation sector accounts for one-third of the total greenhouse gas emissions produced in Norway (~16.5 million tons of CO2), with road traffic accounting for ~10 million tons of CO2. Norway's transport mix is heavily influenced by its low population density, narrow shape and long coastline with many small islands. The Norwegian Ministry of Transport and Communications has overall responsibility for the civil aviation, public roads and rail transport sector, ferry services forming part of the national road system (i.e. coastal regions), for coastal management, the marine environment and port and sea transport policy. They also have the ability to delegate tasks related to public transport and roads to the designated counties and municipalities. The majority of infrastructure in Norway is publicly owned, with operations often contracted out to private firms.

Public transport in and around urban populations is well developed, particularly in Oslo which has one of the most advanced public transportation systems in Europe boasting metro, bus, tram and ferry networks that are all integrated on a zone-based fare system with the latest technology. However, regions with low populations do often lack public transport infrastructure, forcing inhabitants to have their own car. Public transport is subsidized by the government.

Rail transport

Trains produced ~18-36g/km of CO2, depending on capacity of the train. The main railway network in Norway consists of 4,087 km (2,556 mi) of standard gauge lines, of which 242 km (150 mi) is double track and 64 km (40 mi) is high-speed rail (with speeds up to 210 km/h). 2,622 km (64%) is electrified through a 15 kV 162⁄3 Hz AC with overhead wires. This enables significant reductions in greenhouse gas emissions given that 98% (134TWh) of Norway's electricity sector is power by renewable energy (129TWh or 95% of which is produced by hydroelectricity). The only sections that are not electrified are the lines north of Miøsa (except the Dovre and Ofoten Line). Diesel locomotives run the non-electrified sections. All of the urban railways use 750 V DC via overhead wires on the tramways and third rail on the Oslo T-bane. The railways transported 73,836,237 passengers’ 3,555 million km in 2015, with the transport of goods seeing 31,585,437 tons of cargo 3,498 million km.

Road transport

Cars

Norway's fleet of electric cars is one of the cleanest in the world due to its high abundance of electricity generated by hydropower (98%). This has steadily grown in interest, with the end of 2016 seeing 5% (135,000) of all passenger cars on Norwegian roads being a plug-in (Figure 2). Government incentives include being exempt from all non-recurring vehicle fees (including purchase tax and 25% VAT on purchase), a tax reduction for plug-in hybrids and free access to road ferries. These in certain municipalities they can park for free and use public transport lanes. This successful integration of policies has seen electric vehicles widely accepted in Norway and the public even had the chance to discuss and propose ideas for the governments National Transport Plan (NTP). This led to the NTP setting the goal that all new cars; buses and light commercial vehicles should be zero emission vehicles (i.e. all-electric or hydrogen powered) by 2025. However, there have been some side effects with excessively high public subsidies, increased traffic congestion in public transport lanes, shortage of parking spaces for conventional cars (intentional) and loss of revenue for ferry operators.

About half of new cars in Norway in January–June 2019 were electric cars and a quarter in the same period 2018. As of March 2020, 55.9% of the car sales in Norway were electric cars, 26.4% were hybrids (with or without plugs). By 2023, electric cars constituted 24% of all personal vehicles on Norwegian roads.

Buses

Each county is responsible for the public bus and boat transport in their area, with railways, regional airlines and the Coastal boat all being financed by the state. In 2015, buses transported 356 million passengers over 4 billion passenger km. In an attempt to meet their plan to be carbon-neutral by 2050 (conditional for 2030) Oslo is also converting municipal buses to run on biomethane captured from human waste in order to cut CO2 emissions (saves 44 tons of CO2 per bus per year compared to gas alternatives).

Civil aviation

Civil aviation produced ~220-455g/km of CO2, depending on capacity of the plane. Norway has 98 airports, of which 51 facilitate public flights, including one heliport. 45/51 are owned by the government through it airport operator, Avinor. Norway is the country in Europe with the most airline trips per capita, and the routes from Oslo to Trondheim, Bergen and Stavanger are all amongst the ten busiest in Europe. Contributing factors include poor rail and road infrastructure in areas with a low population density, rugged geography and a limited population in the interior and north. The main gateway by air to Norway is Oslo Airport (Gardermoen), located 50 km north of Oslo and primarily services both major Norwegian airlines; Scandinavian Airlines System and Norwegian Air Shuttle.

Water transport

Car ferries are vital links across fjords and to islands where there is no fixed connection. There are currently over one hundred car ferry connections in Norway. In 2015, boats transported 11 million passengers to their destination, a 10% growth from 2014. Norway even has started to install battery-electric ferries and has plans to expand the current fleet, powered by the large amount of hydroelectricity. The Coastal Express (known as Hurtigruten) operates daily from Bergen to Kirkenes, stopping at 35 ports. This is pleasing news on a regional and national level but fails to address their huge international fleet as shipping and aircraft regulations where notably absent from the Paris Agreement.

Fossil fuel production

Norway has a strong ranking of 17 out of 180 countries analyzed in 2016. However, it is one of the world's largest oil exporter and has the largest sovereign fund of any country. In 2015, Norway produced 53.9 million tonnes of greenhouse gases (GHGs) with 15.1 million tonnes attributed to oil and gas extraction. This was higher than any other source of emissions, including energy supply, agriculture and road traffic. The total emissions of GHGs increased by 600,000 tonnes since 2014, with emissions from oil and gas extraction increasing by 83.3% since 1990. In more detail, a 25% increase CO2 emissions, 10% decrease in methane, 38% decrease in nitrous oxide; 44.7 million tonnes (Mt) was CO2, 5.5 Mt of CH4, 2.6 Mt of N2O (Figure 1).

The petroleum and natural gas production on the Norwegian continental shelf utilizes pipelines totaling 9,481 km to transport products to processing plants and onwards to other European countries.

Industrial emissions

Mining and quarrying

12 million tonnes of CO2 equivalents and 66 TWh were used by the manufacturing mining and quarrying industry in 2015 - a 39% emissions reduction since 1990, second only to oil and gas extraction. This industry is showing a downward trend in emissions, but there was an increase between 2014 and 2015 of 3.1%.

Agriculture

Higher production and use of fertilizer in 2015 contributed notably to higher CO2 and nitrous oxide emissions, which was also the largest proportion of agricultural emission causes. The agricultural sector emitted 4.5 million tonnes of CO2 equivalents, but these emissions have been steadily decreasing since 1967.
