Regional Ecological Summit

Regional Ecological Summit in Astana Produces Ecology Declaration and Broader Regional Agenda

Central Asian leaders have adopted the Astana declaration on ecology and sustainable development, giving the Regional Ecological Summit in Astana a formal political outcome while a wider package of biodiversity, climate, and pollution initiatives takes shape around it. Kazakhstan’s environment ministry says the five heads of state adopted the document, titled “Ecological Solidarity of Central Asia,” during the April 22 to 24 Summit. The declaration sets out a common regional position on several of Central Asia’s biggest environmental pressures. According to the ministry summary, the text calls for closer coordination in climate negotiations, glacier preservation, the mountain agenda, biodiversity, chemical and waste management, plastic pollution, air quality, land degradation, and desertification. It also presents the declaration as a contribution to ecological sustainability, inclusive economic growth, and a sustainable future for the region. Water runs through the document, but the language is careful. The declaration welcomes work on an interstate program to conserve the Caspian Sea and expresses concern about declining water levels and the shallowing of lakes in Central Asia. It also notes Kazakhstan’s proposal for a possible International Water Organization within the United Nations system, but stops short of endorsing its creation. The summit’s outcome does not rest on a single document. On April 24, the United Nations Environment Programme said the Astana meeting had launched new regional partnerships on circular economy and glaciers, while countries established common approaches on biodiversity, climate action, and air pollution. UNEP also said a regional climate and ecology investment portfolio was set up to widen access to international finance for environmental projects. A separate biodiversity track had already produced its own result earlier in the week. On April 22, UNDP in Kazakhstan said Central Asian countries had signed a regional declaration on biodiversity conservation during a high-level plenary session in Astana. According to UNDP, the document envisages an umbrella programme and action plan, as well as a regional resource mobilization plan to be presented at COP17 in Armenia. Outside confirmation of the main declaration has also become clearer. EFE reported on April 22 that the five Central Asian republics had approved the Astana Declaration of Ecological Solidarity, linking it to Tokayev’s focus on water security, the Aral Sea, and the Caspian. Put together, the Astana summit now looks like a broader regional attempt to turn shared ecological pressure into a workable political agenda. The summit’s next test will be whether these declarations and partnerships are followed by funding, coordination, and cross-border implementation.

Air Quality Report Shows Central Asia’s Air Getting Rapidly Worse

Tajikistan ranked as the world’s third most polluted country in 2025, according to the latest World Air Quality Report by IQAir. The report analyzed PM2.5 concentrations across 9,446 cities in 143 countries and territories. PM2.5, fine particulate matter measured in micrograms per cubic meter, is widely used as a key indicator of air pollution. The five most polluted countries in 2025 were Pakistan (67.3 µg/m³), Bangladesh (66.1 µg/m³), Tajikistan (57.3 µg/m³), Chad (53.6 µg/m³), and the Democratic Republic of the Congo (50.2 µg/m³). Only 13 countries and territories met the World Health Organization annual PM2.5 guideline of 5 µg/m³, including Australia, Iceland, and Estonia. Overall, 130 out of 143 countries exceeded the guideline. Kazakhstan records the cleanest air in Central Asia, but still had the 29th worst air globally in 2025, a very significant decline from 71st in 2024. Uzbekistan has the region's dirtiest air, and the 10th worst worldwide, while Kyrgyzstan is only slightly better, in 19th. Like Kazakhstan, both countries have fallen down the rankings since they were last put together in 2024. Kyrgyzstan had been in 41st place, while Uzbekistan has fallen from 19th. Turkmenistan, which was also among the 30 most polluted countries in 2024, was not included in the 2025 report due to a lack of available data. Karaganda in Kazakhstan is Central Asia's most polluted city, ranking 26th globally in 2025. The city recorded an annual PM2.5 level of 72.6 µg/m³, more than ten times the WHO guideline. Other heavily polluted cities in the region included Fergana (30th, 68.8 µg/m³), Dushanbe (51st, 57.3 µg/m³), Guliston (100th), and Tashkent (225th, 39 µg/m³). The report also noted that the world’s 25 most polluted cities in 2025 were all located in India, Pakistan, and China, with India accounting for three of the top four.

Uzbekistan Launches “Clean Air” Project to Cut Pollution by 2030

Uzbekistan has approved a nationwide environmental initiative aimed at improving air quality and reducing pollution over the next five years, according to a presidential decree published on March 25. The decree outlines the implementation of the “Clean Air” national project for 2026-2030. The program sets a target of reducing harmful emissions into the atmosphere by 10.5% and strengthening environmental monitoring across key industrial sectors. Under the plan, enterprises classified as having a significant environmental impact will be required to install automatic monitoring systems, as well as dust and gas purification equipment. The initiative also aims to reduce the number of days when air pollution levels, particularly fine particulate matter (PM2.5), exceed national safety standards. Special attention is being given to the capital. Authorities have extended the mandate of a government commission tasked with addressing environmental challenges in Tashkent until March 1, 2027. The body has also been elevated to a national-level commission, reflecting its expanded scope of responsibility. From April 1, 2026, a moratorium will be introduced on the creation of new industrial zones in Tashkent, with no specified end date. The measure is intended to limit additional pressure on the city’s already strained air quality. The decree also introduces stricter environmental requirements in the construction sector starting June 1. Developers will be required to equip building sites with environmental monitoring systems linked to a centralized database managed by the Ecology Committee. In addition, construction sites must install online surveillance cameras to ensure compliance with environmental standards. Companies found to be in violation of environmental regulations will face penalties through a rating system within the national “Transparent Construction” platform. Environmental impact assessments will also become mandatory for all major construction and urban planning projects. New building designs exceeding specified size thresholds must allocate at least 30% of land area to green spaces, reflecting a broader effort to expand urban greenery. In recent years, air quality in Tashkent has deteriorated significantly. Experts attribute the problem to industrial emissions, seasonal dust storms, rapid urban development, and the loss of green spaces. Despite a formal ban, an estimated 49,000 trees have been cut down since 2019. According to the Ministry of Ecology, PM2.5 levels in the capital frequently exceed World Health Organization guidelines. During severe smog episodes in early 2024, pollution levels reached up to 22 times the recommended annual limits, posing serious risks to public health.

Report Reveals Persistently High Air Pollution Levels in Bishkek and Osh

Air pollution remains one of Kyrgyzstan’s most serious environmental challenges, particularly in the cities of Bishkek and Osh, where coal-based heating and motor vehicle emissions are identified as the main sources of pollution, according to a report by the environmental organisation MoveGreen. The study, covering the period from December 2024 to November 2025, found that Bishkek experienced between 118 and 120 days during which concentrations of fine particulate matter (PM2.5) exceeded permissible limits. Average annual levels were estimated at between 44 and 47 micrograms per cubic meter, significantly above the World Health Organization’s recommended guideline of 5 micrograms per cubic meter. Air quality in the capital shows strong seasonal variation. Pollution levels rise sharply during winter due to increased coal consumption for heating and the accumulation of emissions linked to the city’s geographical setting. As a result, Bishkek has frequently ranked among the world’s most polluted urban areas in international air quality monitoring indices. In Osh, pollution patterns were described as more stable but still concerning. Elevated PM2.5 levels were recorded for 159 days during the study period, nearly half the year. The city’s average annual concentration reached 74 micrograms per cubic meter, far exceeding international health recommendations. The report’s authors also noted that concentrations of other pollutants, including nitrogen oxides and formaldehyde, tend to increase during warmer months. Among the key recommendations outlined in the study are a gradual transition to cleaner heating sources, expansion and modernisation of public transport systems, measures to reduce dust pollution in urban areas, and improvements in air quality monitoring infrastructure.

Traffic regulations

Kazakhstan May Introduce Traffic Restrictions Based on Beijing Model

Kazakhstan’s Ministry of Ecology and Natural Resources has proposed that city authorities draw on Beijing’s experience in restricting private vehicle traffic on days with unfavorable weather conditions as part of efforts to combat air pollution. Beijing has operated an “even-odd” traffic system since 2011, under which vehicles with even-numbered license plates may drive on even dates, and those with odd-numbered plates on odd dates. While the measure in the Chinese capital was initially introduced to reduce traffic congestion, in Kazakhstan, it is being considered primarily as a tool to improve air quality. After reviewing Beijing’s practice, the ministry has instructed local authorities and regional environmental departments to prepare air protection plans for 2026-2028, including the possible introduction of similar restrictions. The ministry cited data from Kazhydromet indicating that by the end of 2025, eleven cities in Kazakhstan are expected to record persistently high levels of air pollution. The most affected cities remain Almaty, Ust-Kamenogorsk, Karaganda, Temirtau, and Aktobe. Despite the modernization of major industrial facilities and the adoption of best available technologies, a significant share of emissions originates from smaller sources, including motor vehicles, private households, and small businesses. In Almaty, approximately 60% of emissions are attributed to transport, while a further 12% comes from private homes and small boiler houses. A similar pattern is observed in Ust-Kamenogorsk. In response, the Ministry of Ecology has proposed that city authorities not only consider temporary traffic restrictions during periods of unfavorable weather but also accelerate the transition of public transport and taxis to electric and gas-powered vehicles, establish green belts around industrial zones, subsidize the gasification of private homes, promote connections to centralized heating systems, and ban the use of solid fuels in catering establishments and small boiler houses. The Times of Central Asia previously reported that the most severe smog and adverse weather conditions have recently been recorded in Ust-Kamenogorsk.

Choking on Smog: Air Crisis in Öskemen Deepens

Heavy smog and sustained NMU-II adverse meteorological conditions reported by Kazhydromet continue to affect the city of Öskemen (Ust-Kamenogorsk) in eastern Kazakhstan, after authorities moved all students in grades 0–11 to remote learning on February 2. The decision followed several days of windless weather and a temperature inversion that trapped pollutants close to the ground. According to Kazhydromet forecasts, unfavorable meteorological conditions are likely to remain in place, limiting dispersion. Air quality monitoring platforms show persistent spikes in fine particulate matter, raising renewed health concerns among residents. Data from IQAir indicates that PM2.5 concentrations in Öskemen have at times reached levels classified as “hazardous,” significantly exceeding World Health Organization guidelines. Live readings continue to fluctuate depending on wind and temperature shifts, but pollution levels remain elevated compared to recommended norms. Local authorities say the health of students remains the priority. The regional Department of Education confirmed that distance learning was introduced as a precautionary measure during the NMU-II period. Environmental specialists have advised residents to reduce outdoor activity, particularly children, the elderly, and those with respiratory conditions. What’s Behind the Smog? Specialists attribute the pollution to a combination of meteorological and structural factors. A temperature inversion has created what meteorologists describe as a “thermal cap,” with warmer air overlaying colder surface air, preventing pollutants from dispersing. The absence of sustained wind has compounded the buildup. Öskemen is also one of Kazakhstan’s most industrialized cities, home to major metallurgical enterprises, a coal-fired thermal power plant, and titanium-magnesium production facilities. Vehicle emissions and winter heating from coal and firewood in private homes add to the concentration of fine particulate matter. The city’s geography further complicates the situation. Surrounded by mountainous terrain, Öskemen experiences restricted air circulation during stagnant winter conditions, allowing pollution to accumulate. Monitoring and Mitigation The East Kazakhstan Department of Ecology reported that an interagency task force, including Kazhydromet meteorologists and sanitary inspectors, conducted mobile laboratory monitoring during the peak of the episode. Authorities said industrial facilities reduced output under NMU protocols and that transport and municipal services were instructed to limit emissions. Officials stated that monitored pollutants, including carbon monoxide, nitrogen oxides, sulfur compounds, chlorides, and suspended particles, were measured daily. While authorities described overall average indicators as remaining within permissible limits, independent monitoring services recorded significantly higher short-term PM2.5 spikes. Public Reaction Residents have expressed frustration online, posting photos and videos showing the city enveloped in haze. In comments responding to official statements, users described sore throats, headaches, and difficulty breathing. One resident wrote: “It’s impossible to breathe in the city. This isn’t exaggeration, it’s reality. You, your children, your loved ones are breathing this air.” Others questioned the official assessment, asking why schools were closed if pollution posed no threat to public health. What Comes Next? Kazhydromet forecasts suggest that wind and snowfall could help disperse accumulated pollutants in the coming days. However, recurring winter smog episodes have reignited debate over industrial emissions, household coal use, and long-term urban air quality policy. In early February, regional Maslikhat...
