As at end 2019, overall world's proven natural gas reserves were estimated at 198,800 billion cubic meters or "bcm", which represents more than 50 years of consumption at the current pace. 38% of these reserves are located in the Middle East, 30% in Russia and Turkmenistan, 8% in North America (mainly in the United States), 7.5% in Africa (mainly in Algeria and Nigeria) and only 1.7% in Europe (mainly in Norway, Ukraine, the Netherlands and the United Kingdom). The remainder is divided between South America and the Asia-Pacific region.

New gas fields are found on a regular basis, transforming so-called "probable" reserves into "proved" reserves. As a result, the estimated deadline for the depletion of this resource is constantly being extended. Since natural gas is fossil, it will however have to be gradually replaced by renewable gases (biogas, synthetic methane or hydrogen) to reduce greenhouse gas emissions.

The world's largest gas producers are the United States (921 bcm in 2019), followed by Russia (679 bcm), Iran (244 bcm) and Qatar (178 bcm). In Europe, Norway produced 114 bcm in 2019, the United Kingdom 40 bcm and the Netherlands 28 bcm. Over the last decade, Qatar's production has grown by 7% per year, while the United States' production has increased by 5% per year as a result of development. In Russia production has risen by 2.5% per year and in Norway by almost 1%.

Production in Europe, excluding Norway, is on the other hand down: in the Netherlands, production has declined by 8% per year over the last decade with the gradual decommissioning of the Groningen gas field. While reserves in the North Sea are dwindling, production in the United Kingdom is also declining (-4% per year).


••• Unconventional gas •••  The rapid expansion of so-called unconventional gas exploitation on the North American continent over the last decade has dramatically reshaped the world gas market. New drilling and hydraulic rock fracturing technologies have increased productivity and reduced production costs. The greater agility that characterizes these technologies allows producers to react quickly to market price signals. As a result, the United States has become the world's largest producer of natural gas.

World gas production (bcm/year)

The leading gas-consuming countries in the world in 2019 were the United States (847 bcm), Russia (444 bcm) and China (307 bcm). Europe consumed approximately 554 bcm (or 5,412 TWh) of gas that year. The three largest European consumers in 2019 were Germany (89 bcm), the United Kingdom (79 bcm) and Italy (71 bcm). With 3.9 bcm, or 38 TWh, Switzerland thus consumed 0.7% of European gas. In one decade (2009 - 2019), overall gas consumption increased by 3% per year. While gas consumption was stable in Europe and Switzerland, it increased by 13% per year in China and 3% in the United States. The US very low natural gas prices resulting from abundant supplies are gradually leading to the decommissioning of coal-fired power plants.


In 2019, 80% of Europe's natural gas supply was carried out by pipelines and 20% by LNG carriers.

European gas pipeline networks stretch from Siberia to Spain, from Azerbaijan to the gas fields in the North Sea (United Kingdom) and from Algeria to the Atlantic Ocean off the coast of Norway.

In 2019, Europe imported by pipeline 188 bcm from Russia, 109 bcm from Norway, 38 bcm from the Netherlands and 21 bcm from Algeria. The balance came from Iran, Libya and Azerbaijan.


••• Nord Stream ••• The construction of the Nord Stream 1 pipeline began in 2005. It was commissioned in 2012. It is 1,222 km long and connects Vyborg in northern Russia to Greifswald in Germany under the Baltic Sea. The Nord Stream 2 project, a twin pipeline system designed to double the capacity of the existing Nord Stream 1 link, started in 2018. At the end of 2019, however, work was suspended following opposition and US sanctions. View more.

••• Trans Adriatic Pipeline (TAP) ••• Connected to the Trans-Anatolian Natural Gas Pipeline at the Greek-Turkish border, the TAP crosses northern Greece, Albania and the Adriatic Sea before reaching Italy. It is 878 km long and was commissioned in November 2020. View more.


Imports of liquefied natural gas (LNG) reached 120 bcm in 2019, a rise of 68% over 2018. This leap was catalyzed by the outstanding expansion of liquefaction plants in Qatar, the United States and the Yamal Peninsula on the Arctic Ocean in Russia. Thus 32 bcm of the LNG imported by Europe originated from Qatar, 20 bcm from Russia, 18 bcm from the United States, 16 bcm from Nigeria and 15 bcm from Algeria. The balance came from Trinidad & Tobago, Norway, Egypt, Angola and Peru.


••• EastMed ••• The Eastern Mediterranean (EastMed) natural gas pipeline project is expected to be one of the longest in the world (1,900 km), connecting the eastern Mediterranean to southern Europe. The pipeline is expected to bring newly discovered gas off the Cypriot and Israeli coasts to Europe, thus diversifying the supply sources. Cyprus, Greece and Israel signed an interstate agreement in 2020 and the pipeline is expected to be commissioned in 2027. View more


European regasification terminals are located in Belgium, France, Greece, Italy, the United Kingdom, Spain and the Netherlands.


••• LNG Terminal Wilhelmshaven (LTeW) ••• Germany is planning to build a Floating Storage and Regasification Unit (FSRU) in Wilhelmshaven. This technology has the advantage of being less expensive and easier and quicker to implement than a land-based terminal. View more.


Switzerland's supply is ensured by a good connection to the major gas transmission lines in Europe.

The main entry point for natural gas into Switzerland is at the German border at Wallbach (east of Basel). The TENP (Trans Europa Naturgas Pipeline) is interconnected with the Transitgas pipeline to supply mainly northern Italy with gas from Russia and the North Sea. The pipeline crosses the Italian border at the Griess Pass. 10% of Transitgas' North-South flows remain in Switzerland for domestic supply. The Transitgas pipeline also transports natural gas from France. The entry point is located at Oltingen (west of Basel).

The other entry points of the Swiss networks are: Bardonnex/ La Louvière (in Geneva), La Cure (near Saint-Cergue in the Jura vaudois), Schönenbuch (in Basel), Fallentor (in Schaffhausen). The Ticino region is not connected to the Swiss networks and is supplied from Italy.
