Iran Energy and Environment Facts

Natural resources, energy and environment

Iran has very large known reserves of both natural gas and oil. This represents almost one fifth of the known natural gas in the world and almost one tenth of the oil reserves. In addition, there are plenty of minerals in the country such as iron, coal, zinc, nickel, sulfur, chromium and copper.

Oil has been mined since the beginning of the 20th century. Most of the oil wells are in the Khuzestan province, but there are also oil fields in the Persian Gulf. The recovery was greatest in the 1970s when it reached the highest level of 6 million barrels a day.

  • COUNTRYAAH: Major exports by Iran with a full list of the top products exported by the country. Includes trade value in U.S. dollars and the percentage for each product category.

The 1979 revolution, the war against Iraq in the 1980s and foreign sanctions in recent years (see Modern History and Current Policy) have contributed to oil production not reaching the same levels as before. The increasingly severe sanctions also caused Iran to lose importance as an oil exporting country. After most sanctions were lifted in 2016, Iran could gradually begin to regain its position on the world market. When the United States reintroduced all its sanctions in 2018, it led to major economic problems for Iran, despite several of the country’s major oil customers being temporarily exempted from US threats of punishment.

Production, refining, distribution and export are handled by the State National Iranian Oil Company (Nioc) and its many subsidiaries. The constitution prohibits foreign and private ownership of natural assets, but since the beginning of the 1990s, foreign oil and gas companies have been allowed to invest in the country. They were responsible for financing and technology when a new oil or gas field was exploited, and then replaced by a repurchase mechanism when Nioc started production. The foreign companies have no ownership rights in the fields and receive no share in the profits once the investment has been paid. In recent years, Western companies have been forced to submit projects because of the sanctions. China, on the other hand, chose to increase cooperation with large investments in the oil and gas fields, but China has subsequently slowed down. This was the case with the first major new contract with a Western company that was concluded in 2016, after the sanctions were lifted. French Total then signed a 20-year contract worth € 4.3 billion to develop a new offshore gas field in collaboration with an Iranian and a Chinese company. Total then became one of the companies affected by reintroduced US sanctions, and in 2019 Iran announced that China had also withdrawn.

Extensive extraction of a variety of metals and other products is ongoing throughout Iran. The mine in Sar Cheshmeh is estimated to have the second largest copper deposits in the world. Iran also has assets of lead, uranium, gold, phosphate and bauxite.

Electricity production has increased during the 2000s, but demand is increasing faster, especially from industry. Since electricity is subsidized, it is consumed unnecessarily. Electricity zoning occurs, but virtually all residents have access to electricity. Fossil fuels – mainly natural gas but also oil and to a small extent coal – account for over 90 percent of the electricity produced. The rest comes mainly from hydropower.

The first electricity deliveries from nuclear power came in 2011, but production is still on a modest scale. In 2016 it was announced that two new nuclear reactors would be built with Russian help and be ready after ten years. Iran claims that all nuclear energy production is for civilian purposes and cooperation with Russia continues. When the US withdrew from the International Nuclear Energy Agreement with Iran, which was concluded in 2015, the civil partnerships established were allowed to continue. A cloud of concern next to big politics is that earthquakes are common in Iran. At New Year 2020, two earthquakes were reported near the nuclear power plant in Bushehr.


The Caspian Sea is the world’s largest lake. Along the beaches, seals used to be a common sight. An estimated one-tenth of the stock that existed about 100 years ago now remains. The species is considered endangered by hunting and industrial emissions, not least from oil recovery. The UN environmental program Unep has warned against large quantities of uncontaminated wastewater, but also radioactive substances from nuclear power plants. Much of the pollution reaches the lake from the Volga River in Russia, which flows into the Caspian Sea. Also, the stocks of the valuable deer, which are fished for caviar, have decreased dramatically.

Emissions of oil and chemicals have damaged marine life both in the Persian Gulf and the Caspian Sea. In cities, emissions from industries and cars create bad air. Most cars lack catalysts and use gasoline with lead. The Iranian motorist drives more than most because of the very low gasoline price. Tehran is ranked as one of the world’s most polluted cities. There is also a lack of clean water. Uncleaned wastewater from industries and cities drains into the watercourses, poisoning them and posing a threat to the country’s fresh water reservoirs.

Much of Iran’s territory has been affected by land degradation due to intensive grazing, logging and desertification (see also Agriculture and Fisheries). The problem is particularly evident at Lake Urmia in the northwest, which was previously considered the world’s sixth largest saltwater lake. Through a combination of drought and dams, the lake has lost 95 percent of its water and more than two-thirds of its surface in a couple of decades. In 2014, President Rohani estimated the equivalent of five billion US dollars in ten years to try to save the lake from disappearing completely.

Two natural areas are on UNESCO’s World Heritage List: the salt desert Lut and a very old forest on the Caspian Sea that has unusually large biodiversity.
