Almaty Grapples with Year-Round Nitrogen Dioxide Crisis, Study Warns

A new study has revealed persistently dangerous levels of nitrogen dioxide (NO₂) pollution in Almaty, Kazakhstan’s largest city, with motor vehicles identified as the primary source. Conducted by the Almaty Air Initiative over 2023-2024, the research highlights aging vehicles, inadequate emissions oversight, and coal-based heating as key contributors to chronically high NO₂ levels throughout the year. With more than 600,000 vehicles on the roads daily, Almaty’s outdated and poorly regulated transport fleet is having a significant environmental impact. According to the Ministry of Internal Affairs, nearly one-third of the city’s vehicles are over 20 years old, many lacking catalytic converters that are standard in other countries. NO₂ Levels Far Exceed Global Health Standards Data from over 50 monitoring stations, installed as part of an Asian Development Bank-supported program, show that annual NO₂ concentrations in Almaty were 4.6 times higher than the World Health Organization’s recommended limits in 2023, and 4.2 times higher in 2024. Only 16 days in 2024 met the WHO’s daily NO₂ threshold of 25 µg/m³. On 143 days, concentrations exceeded 40 µg/m³, posing health risks to vulnerable groups such as children, the elderly, and people with respiratory issues. On seven days, levels surpassed 100 µg/m³, considered extremely hazardous for the general population. Kazhydromet, Kazakhstan’s national weather agency, documented over 11,000 violations of the country’s maximum permissible concentration (MPC) for NO₂ in 2024, an average of nearly 30 per day. Pollution Persists Across All Seasons Unlike particulate matter (PM2.5), which typically spikes during the heating season, NO₂ pollution remains elevated year-round. Peak monthly averages reached nearly 100 µg/m³ in January 2023 and 80 µg/m³ in December 2024. Even in summer, concentrations hovered around 30-35 µg/m³, well above WHO guidelines. In 2024, Almaty recorded 164 “clean” days based on PM2.5 levels (below the WHO’s 15 µg/m³ threshold), but just 16 days met the corresponding standard for NO₂, underscoring the pollutant’s persistent presence and underrecognized health risks. Additional Contributors: Coal and Industry Beyond traffic emissions, NO₂ levels are exacerbated by emissions from two coal-fired thermal power plants, as well as numerous private heating systems and small-scale boiler houses. The study also criticized Kazakhstan’s vehicle inspection system, which it says fails to identify or enforce emissions violations. Study Urges Comprehensive Action To tackle the NO₂ crisis, researchers recommend a suite of policy measures, including: Transitioning public transport to gas and electric power Phasing out coal-based heating in favor of gas Installing emissions filters at thermal power plants and residential heating units Establishing low-emission zones across Almaty Encouraging walking and cycling for short trips Strengthening vehicle inspection and emissions monitoring systems With NO₂ now considered one of the most serious and persistent air quality threats in Central Asia, Almaty’s situation serves as a stark warning for other rapidly urbanizing cities in the region.

Bishkek Launches “Living Wall” Project to Tackle Heat and Pollution

Bishkek has launched a pilot project to green the facades of buildings as part of a broader effort to adapt to climate change and mitigate growing heat and air pollution in Kyrgyzstan’s capital. In June, vertical greenery was installed on the facades of three schools and one apartment building under the “1000 Green Walls” program. The initiative is jointly implemented by the environmental organization MoveGreen and the Bishkek municipality, with support from the United Nations Environment Programme (UNEP) and the development agency Bread for the World. More Than Just Aesthetic Green facades, also known as living walls, offer both visual and environmental benefits. They reduce building surface temperatures, absorb carbon dioxide, release oxygen, and filter dust and pollutants from the air. These vertical gardens also improve sound insulation, protect buildings from temperature extremes, and support urban biodiversity, providing habitat for birds, insects, and butterflies. Two species were selected for the pilot phase: maiden grapes and ivy. Maiden grapes are fast-growing, frost- and drought-resistant vines that create dense green coverage. In addition to insulating buildings, they absorb dust and exhaust emissions, improving local air quality. Their vibrant red foliage in autumn also enhances the city’s visual appeal. Ivy, an evergreen perennial, retains its foliage year-round and provides consistent thermal and acoustic insulation. It is effective in trapping airborne pollutants and helps create a more temperate and pleasant microclimate around buildings. A Scalable Urban Solution The Bishkek municipality views this as a sustainable and scalable urban solution. “These green facades contribute to a more comfortable, ecological, and aesthetically pleasing urban environment,” officials said. The city plans to expand the 1000 Green Walls program to include more schools, kindergartens, and residential buildings in the coming months.

World Bank: Over 65,000 Premature Deaths a Year in Central Asia Linked To Air Pollution

Air pollution remains one of the most pressing environmental and public health challenges in Central Asia, with significant consequences for human life and regional economies. A new World Bank assessment highlights the scale of the crisis, linking poor air quality to more than 65,000 premature deaths in 2021 across the region. The report identifies pollution from fossil fuel combustion, especially for heating and transportation, as a major contributor to declining air quality in both urban and rural areas. Transboundary sand and dust storms are compounding the problem, affecting multiple countries simultaneously. In many Central Asian cities, concentrations of fine particulate matter (PM2.5) exceed safe limits by a wide margin. During the winter, levels can spike to six to twelve times higher than the World Health Organization’s recommended thresholds. The economic burden is also staggering: the annual health costs associated with air pollution are estimated at $15-21 billion, representing 3-5% of the region’s GDP in 2022. Human-Caused Emissions Dominate According to experts, 50-80% of PM2.5 exposure is due to human activity, primarily the burning of solid fuels for heating in households and small businesses. While natural dust is a contributing factor in some areas, anthropogenic sources remain the dominant driver. The World Bank argues that this crisis can be mitigated with the right policy interventions. Effective strategies include reducing emissions from household heating, traffic, and industrial operations, as well as expanding urban green spaces. To better coordinate efforts, the Bank advocates for an “airshed approach”, a governance model that promotes joint responsibility between national and local authorities to improve air quality. Additional recommendations include strengthening air quality laws and monitoring systems, updating standards, raising public awareness, and enhancing cross-border cooperation among Central Asian states. Impact on Children A separate report by UNICEF underscores the disproportionate toll air pollution takes on children. In 2021, approximately 6,441 children and teenagers across Europe and Central Asia died from air pollution-related causes, 85% of them under the age of one. UNICEF stressed that these deaths were entirely preventable. Experts maintain that improving air quality could yield wide-ranging benefits, including increased productivity, reduced healthcare costs, and enhanced quality of life. They urge governments to integrate air quality management into climate and development plans to unlock additional financial and technical assistance.

EDB Evaluates Environmental Projects to Combat Air Pollution in Bishkek

The Bishkek municipality and the Eurasian Development Bank’s (EDB) Fund for Digital Initiatives are considering two major environmental projects to tackle air pollution and enhance the quality of life in Kyrgyzstan’s capital. The proposals were reviewed during a meeting on May 21 between Bishkek Mayor Aibek Junushaliyev and Tigran Sargsyan, Deputy Chairman of the EDB Management Board and head of the EDB's Fund for Digital Initiatives. According to the municipal government, the first project involves establishing a comprehensive air quality monitoring system based on a digital platform. The system is designed to address the city’s chronic air pollution by providing government bodies with real-time data on key emission sources. It would also enable assessments of contributions from industrial activities and natural background pollutants. The second project envisions an intelligent transport monitoring system aimed at improving traffic flow modeling and management. The goal is to optimize the city’s public transport network, reduce congestion, and enhance urban mobility, all while improving environmental conditions. Transport and Air Quality: Pressing Challenges for Bishkek Traffic congestion and outdated public transport are among the most pressing issues in Bishkek, a city undergoing rapid population growth. According to the Ministry of Natural Resources, Ecology, and Technical Supervision, motor vehicles are responsible for 27% of the city’s air pollution. With over 600,000 registered vehicles, nearly double the city’s road infrastructure capacity of 350,000, Bishkek’s air quality continues to decline. More than 333,000 of these vehicles are over 15 years old, contributing significantly to emissions. Nonetheless, the city has taken steps to modernize its public transport fleet, including replacing aging diesel-powered buses with larger, eco-friendlier models powered by liquefied petroleum gas (LPG). Air pollution is especially severe during the winter months when coal burning for household heating, accounting for 40% of the city’s emissions, surges. As a result, Bishkek frequently ranks among the world’s top 10 most polluted cities on IQAir’s global air quality index. The proposed EDB-backed projects represent a potential turning point for Bishkek’s environmental management strategy, offering digital tools and policy solutions to address longstanding public health and urban planning challenges.

UN Human Rights Commissioner Raises Alarm Over Air Quality in Bishkek

UN High Commissioner for Human Rights Volker Türk has expressed concern over deteriorating air quality in Bishkek during his official visit to Kyrgyzstan. The visit, focused on civil rights, freedom of speech, and economic development, also addressed pressing environmental issues affecting the Kyrgyz capital. Speaking at a press conference, Türk emphasized that Kyrgyzstan ranks among the most polluted countries in the region, and that air quality in Bishkek poses a serious threat to public health and the environment. “Despite some progress and financial support from international organizations, much more needs to be done to protect the environment,” he said. Türk urged Kyrgyz authorities to intensify efforts to combat climate change and to increase investment in green initiatives. He underscored the importance of climate finance and the need for comprehensive, cooperative action. “This issue must be addressed in partnership and through a climate change lens,” he said. “While there have been financial injections from international donors, they have not yet translated into sufficient results. Each country bears responsibility. Green investments are essential, not just for Kyrgyzstan, but for all nations. The government must take stronger, more effective action.” According to the 2024 World Air Quality Report from IQAir, cities across Central Asia consistently exceed World Health Organization (WHO) recommendations for fine particulate matter (PM2.5). The report notes the following annual average concentrations (in micrograms per cubic meter): Dushanbe: 46.3 Tashkent: 31.4 Bishkek: 21.2 Osh: 20.5 Almaty: 20.3 Astana: 15.4 For context, the WHO’s recommended safe limit for PM2.5 is no more than 5 micrograms per cubic meter.
