Environmental issues in Iran

80% of air pollution in Tehran is due to cars; the remaining 20% is due to factories and industry emissions.

Iran is one of the world's largest and most densely populated countries, spanning an area of approximately 1.7 million sq. km and a population of 91.5 million. Since 1966 Iran has experienced immense population growth, initially being recorded at 25,781,090 people, and totaling to 75,330,000 in 2010. The various climates, increased population growth, heavy reliance on fossil fuels, and refusal to commit to sustainability goals has extenuated Iran's vulnerability to ecological crisis and climate change.

Environmental issues in Iran include, especially in urban areas, vehicle emissions, refinery operations, and industrial effluents which contribute to poor air quality. A report by the United Nations Environment Programme ranked Iran at 117th place among 133 countries in terms of environmental indexes.[1][2] Water scarcity is also a concern since the increased temperatures and fluctuating precipitation levels associated with global warming can result in droughts or flooding that will further degrade the water availability.

Car vs public transport in Tehran

The World Bank estimates losses inflicted on Iran's economy as a result of deaths caused by air pollution at $640 million, which is equal to 5.1 trillion rials or 0.57 percent of GDP.[3][needs update] Diseases resulting from air pollution are inflicting losses estimated at $260 million per year or 2.1 trillion rials or 0.23 percent of the GDP on Iran's economy.

Most cars use leaded gasoline and lack emissions control equipment.[4] Tehran is rated as one of the world's most polluted cities. However, buses and cars running on natural gas are planned to replace the existing public transportation fleet in the future. Also, energy prices are kept artificially low in Iran through heavy state subsidies, resulting in highly inefficient and polluting consumption patterns.[5][6] Traffic management, vehicle inspection, general use of electric bicycles and electronic government are also part of the solution.[7]

A rising incidence of respiratory illnesses prompted the city governments of Tehran and Arak, southwest of the capital, to institute air pollution control programs. These programs aim to reduce gradually the amount of harmful chemicals released into the atmosphere.[8]

Climate change

Main article: Climate change in Iran

Iran is party to the Kyoto Protocol on climate change but not its Doha Amendment.[9] It has signed but not ratified the Paris Agreement on climate change.[10]

Ecosystems

Much of Iran's territory suffers from overgrazing, desertification and or deforestation.

Wetlands and bodies of fresh water increasingly are being destroyed as industry and agriculture expand, and oil and chemical spills have harmed aquatic life in the Persian Gulf and the Caspian Sea.[11] Iran contends that the international rush to develop oil and gas reserves in the Caspian Sea presents that region with a new set of environmental threats.[12] Although a Department of Environment has existed since 1971, Iran has not yet developed a policy of sustainable development because short-term economic goals have taken precedence.[13]

Signed, but not ratified: Environmental Modification, Law of the Sea, Marine Life Conservation.[14]

Deforestation

Iran had a 2018 Forest Landscape Integrity Index mean score of 7.67/10, ranking it 34th globally out of 172 countries.[15]

Natural disasters

Further information: List of earthquakes in Iran

Iran experiences periodic droughts, floods, dust storms, sandstorms and earthquakes along western border and in the northeast.[14]

Soil erosion

Iran ranked worst in the world for soil erosion in 2011,[16] with reports from 2017 indicating that the erosion rate in the country is 2.5 times the world average.[17]

Waste

An estimated 50,000 tons of trash is produced in the country every day of which something between 70 and 80 percent is disposed of hygienically but the rest is not.[18] Iran produces over 8 million tons of hazardous waste annually (2016).[19]

Water

Main article: Water supply and sanitation in Iran

Industrial and urban wastewater runoff has contaminated rivers, coastal and underground waters.[citation needed][14]

Water scarcity

This paragraph is an excerpt from Water scarcity in Iran.[]
Water scarcity in Iran is caused by high climatic variability, uneven distribution of water, over exploitation of available water resources,and prioritization of economic development.[20][21] Water scarcity in Iran is further exacerbated by climate change.
