Air pollution is particularly significant in urban areas;[8] the problem is especially acute in Istanbul,[9]Ankara, Erzurum, and Bursa, where the combustion of heating fuels increases particulate density in winter. Almost all the urban population is exposed to particulate matter emissions higher than the EU and World Health Organization limits.[10] Especially in Istanbul, increased car ownership causes frequent urban smog conditions.[11] "Air pollution in urban centers, often caused by transport, and the use of small-scale burning of wood or coal, is linked to a range of health problems." "PM10 levels are 36.7 micrograms per cubic meter, much higher than the OECD average of 20.9 micrograms per cubic meter, and the annual guideline limit of 20 micrograms per cubic meter set by the World Health Organization." Although there is some monitoring of air pollution compared with other European countries, many air pollution indicators are not available.[12] Regulations in Turkey do not contain any restrictions on the pollutant PM 2.5, which causes lung diseases.[13] Greenpeace Mediterranean claim that the Afşin-Elbistancoal-fired plant is the power plant with the highest health risk in Europe, followed by the Soma coal-fired power plant, also in Turkey.[14][15]
Summer temperatures have increased and are expected to continue to increase due to climate change.[18]Coal in Turkey emits a third of the country's greenhouse gas.
Organic pollution of streams is a problem.[19] There is a potential for spills from the 5,000 oil- and gas-carrying ships that pass through the Bosporus annually.
Land degradation is a critical agricultural problem, caused by inappropriate use of agricultural land, overgrazing, or over-fertilization,.[22] Serious soil erosion has occurred in 69% of Turkey's land surface. A national soil information system is being developed as presently 'it is difficult to assess the levels of land degradation, desertification or soil contamination'.[23]
The European Pollutant Release and Transfer Register (E-PRTR) legislation was adopted in 2021 to be phased in.[27] There is a pollutant release and transfer register website but as of September 2024 no years are publicly searchable, because it is not yet technically complete (see FAQ).[28] In 2024 a draft similar to the EU green taxonomy was published.[29]
Environmental issues are becoming more politically sensitive.[30] Changes in the law on environmental impact assessments are being considered which will permit mining investments without waiting for environmental impact assessments.[31] The EU has asked for "a stronger political commitment".[32] In 2019 Turkey was one of five countries which voted against the proposed UN Global Pact for the Environment.[33]
As of 2019[update] Turkey is not a party to the Aarhus Convention, and the EU[38] and OECD say the government should remove restrictions on access to environmental information:[39] researchers say the government is punishing them for publishing information about pollution.[40]

A stronger political commitment would help to accelerate the alignment with and implementation of the acquis, as well as coordination and cooperation between relevant authorities at all levels.
