Shedding light on pathways to clean air and blue skies in the Hindu Kush Himalaya (HKH) region, National Citizen Party’s (NCP) first senior joint member secretary Dr Tasnim Jara on Tuesday emphasised that people must remain at the centre of climate and environmental action. "It’s about our children breathing freely. It’s about them living longer, healthier, more fulfilling lives. If we connect to that human story, it binds us across political lines and across borders," she said while speaking at a high-level panel discussion on the sidelines of the HKH Parliamentarians’ Meet 2025. A popular figure known for her evidence-based health videos with millions of followers, Dr Jara outlined four key steps to tackle air pollution - building a shared scientific foundation, harmonising policies, mobilising finance and keeping people at the centre.

They are the bridge between science and people, between global commitments and local realities. That is why they must step forward and act.” Dr Jara underlined that clean air is not a luxury, but a right. Framing it as a political issue, she said, “If we can secure that commitment across the region, our partners will act together. The sky above belongs to all of us, and we must defend our right to clean air with urgency. We either fix this together, or we fail separately.” Four Priorities Monitoring of air quality in the region is still uneven, said Dr Jara, calling for a robust regional network of monitoring stations, shared datasets, and transparent science.  “If we cannot measure together, we cannot act together." UN Secretary General calls for enhanced global cooperation for clean air “If one country tightens standards but another does not, the consequences cross borders,” she said, urging alignment of policies across the HKH region.

UN Secretary-General António Guterres  has issued a powerful call for increased global cooperation to address the “global emergency” of worsening air pollution. “Global problems require global solutions. We must act together for clean air,” said Guterres marking the International Day of Clean Air for Blue Skies on Thursday. The theme for the fourth annual International Day of Clean Air for blue skies, "Together for Clean Air", highlights the urgent need for stronger partnerships, increased investment, and share responsibility for overcoming air pollution.

Airborne contaminants are one of the most significant environmental health risks. According to the UN World Health Organization (WHO), 99 per cent of the world’s population breathes polluted air, with the exposure significantly worse in low and middle-income countries. The pervasive nature of air pollution requires global collaboration. This year’s theme, Together for Clean Air, addresses the urgent need for stronger international partnerships, increased investment, and collective responsibility to cut air pollution.

Household cookers and other combustion devices, cars, industrial facilities, and forest fires are the most common sources of air pollution. Air pollution exists both outdoors and indoors, and both severely impact human health. Pollutants which are particularly dangerous include carbon monoxide, ozone, nitrogen dioxide, and sulphur dioxide. Air pollution also includes PM2.5, inhalable particulate matter less than 2.5 micrometers in diameter – less than that of human hair. These particulates are invisible to the human eye and can penetrate deep into the lungs where they can cause inflammation, enter the bloodstream, and damage the heart and brain.

Air pollution also affects plants, reduces crop yields and impacts food security. It worsens social and gender inequality, and slows economic development, limiting the ability of countries to meet their development goals. “Exposure at any level can have health implications that impair quality of life and come with costs for the individual, our societies, and our economies,” said Martina Otto, head of the secretariat of the UN Environment Programme (UNEP)-convened Climate and Clean Air Coalition. Solutions to improve air quality vary based on local contexts and sectors. At the individual level, people can initiate change by making decisions that promote clean air, such as making environmentally friendly purchases and using cleaner methods of transportation and cooking. Businesses and corporations can add air quality to corporate social responsibility considerations, monitor and publicly report pollution emissions, and promote programmes that reduce emissions. Governments should create and enforce air pollution standards to achieve milestones outlined in the 2021 World Health Organization guidelines, in addition to increasing their capacity to monitor air quality.

This past July the Dhaka city dwellers got a special treat from the nature. The air they breathed in was much cleaner as the air quality significantly improved thanks largely to pollution-reducing rain, Eid exodus and Covid restrictions. Even Dhaka got a niche among the world’s top ten cities having clean air from July 22-31 last, a relief for an overcrowded city known for its severe air pollution.

According to the data of the US-based IQAir Visual, Dhaka was also among the top five cities for particular times on July 24 and 30 for the good air quality, said Prof Dr Ahmad Kamruzzaman Majumder, the founder and director of Centre for Atmospheric Pollution Studies (CAPS) of Stamford University Bangladesh. The city’s air quality significantly improved in July as its Air Quality Index (AQI) score remained less than 100 in the most of days of the month. The AQI score 0-50 is considered as ‘good’ air quality, while 51-100 as moderate, 101-150 as unhealthy for sensitive groups, 151-200 as unhealthy, 201-300 as very unhealthy and 301 and above as hazardous.

Highlighting the dangers posed by air pollution, UN Secretary-General António Guterres said air pollution causes an estimated seven million premature deaths every year.

With Dhaka battling every day with toxic air, environmental and rights activists think the ‘ineptitude’ of the authorities concerned to protect people from exposure to ‘hazardous’ and ‘unhealthy’ air is a serious violation of human rights.
