Even though heat waves, floods and wildfires are ravaging the planet, it is actually suspended particles in the air that pose the most serious immediate risk to human health, reducing average life spans across the world. Moves to control carbon emissions by switching to renewable energy will help in also reducing pollution thereby improving public health and allowing billions of people around the world to live longer. The <a href="https://aqli.epic.uchicago.edu/wp-content/uploads/2023/08/AQLI_2023_Report-Global_Embargoed.pdf" target="_blank">latest data from the Air Quality Life Index (AQLI)</a> issued by the Energy Policy Institute of the University of Chicago shows that fine soot particles in the air that are less than 2.5 microns (PM2.5) in diameter are the most dangerous. <a href="https://aqli.epic.uchicago.edu/wp-content/uploads/2023/08/Nepal-FactSheet-2023_Embargoed.pdf" target="_blank">Nepal is among countries most affected</a> by particulate air pollution from its own vehicular emissions and open fires, and is downwind in winter from the <a href="https://aqli.epic.uchicago.edu/wp-content/uploads/2023/08/India-FactSheet-2023_Embargoed.pdf" target="_blank">most polluted parts of north India</a>. The <a href="https://uchicago.app.box.com/s/swo06s7b5fvfmn0v4h5eisi37w6a5c6g" target="_blank">report reveals</a> that particulate pollution carries the greatest external risk to human health, with the impact on life expectancy comparable to that of smoking, more than 3 times that of alcohol use and unsafe water, and more than 5 times that of traffic accidents.&nbsp; However, the risk is not spread equally across the world. Six countries in the world are at much greater risk than others and most of them are in Nepal’s neighbourhood.&nbsp; “Three-quarters of air pollution’s impact on global life expectancy occurs in just six countries, Bangladesh, India, Pakistan, China, Nigeria and Indonesia, where people lose one to more than six years off their lives because of the air they breathe,” says Michael Greenstone, Professor in Economics at the Energy Policy Institute at the University of Chicago (EPIC).&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20230829050856_334052e47db863afb0a8d17fe97e67321fd808c7079610bd7e9fa3f97d39933b.png" data-media-id="editor_4" data-image-id="20230829050856_334052e47db863afb0a8d17fe97e67321fd808c7079610bd7e9fa3f97d39933b" data-rendition-name="original" width="1688" height="632" loading="lazy" alt="Air pollutuon"> </figure>  Even though awareness about the danger of pollution is growing, slow changes in state energy policy have not led to meaningful action. The pollution is also being <a href="https://www.nepalitimes.com/here-now/open-air" target="_blank">transported across national boundaries</a>, which means regional cooperation to improve air quality is as important. The first priority is to provide citizens with real-time open air quality data, yet only 6.8% of the Asia knows how dirty their air is. Knowledge about pollution can create public pressure on governments to act. As it is only one-third of the countries in Asia have air quality standards, the basic building block for policies, the AQLI report says. Investment in air quality infrastructure also does not match where air pollution is having its greatest toll on human life.&nbsp; “Timely, reliable, open air quality data in particular can be the backbone of civil society and government clean air efforts—providing the information that people and governments lack and that allows for more informed policy decisions,” says <a href="https://www.youtube.com/watch?v=6mW7YmSSnes&amp;t=50s" target="_blank">Christa Hasenkopf,</a> the director of AQLI and air quality programs at EPIC. “Fortunately, we see an immense opportunity to play a role in reversing this by better targeting—and increasing—our funding dollars to collaboratively build the infrastructure that is missing today.” <div class="embed-block"><iframe width="560" height="315" src="https://www.youtube.com/embed/6mW7YmSSnes?si=qCHCmCfqcMXerxiI" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen></iframe></div> The release of the AQLI report comes just ahead of the UN’s <a href="https://www.un.org/en/observances/clean-air-day" target="_blank">International Day of Clean Air for Blue Skies</a>. While much of multilateral and bilateral development assistance goes to control of diseases like malaria and tuberculosis, the resources for pollution control are much less even though many more people die or are affected by dirty air. The report singles out South Asia, especially its densely-populated northern areas as suffering the deadliest impact of pollution. More than a quarter of the global population in Bangladesh, India, Nepal and Pakistan are the most affected, <a href="https://www.nepalitimes.com/here-now/breathing-can-kill-you" target="_blank">losing five years of their lives on average.</a>&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20230829050852_2853466cd4b12be5cc853762f736bb5b264a752d22354797f35c24f2cd6a1f5b.png" data-media-id="editor_10" data-image-id="20230829050852_2853466cd4b12be5cc853762f736bb5b264a752d22354797f35c24f2cd6a1f5b" data-rendition-name="original" width="1842" height="1118" loading="lazy" alt="Air pollution"> </figure>  Although China had some of the worst air quality 20 years ago, the <a href="https://aqli.epic.uchicago.edu/wp-content/uploads/2023/08/China-FactSheet-2023_Embargoed.pdf" target="_blank">report cites its remarkable success</a> in reducing pollution by 42.3% since 2013, when it declared a ‘war against pollution’.

Cleaner Air = Longer Lives

<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110161156/636d1f909c7e80680e0af470jpeg.jpg" alt="" width="2000" height="2625"/><figcaption>Photo: AMIT MACHAMASI</figcaption></figure>On Thursday morning, Nepali Times photographer Amit Machamasi was greeted with a shocking sight when he drove up to Nagarkot to take pictures of overnight snowfall. Below him, dozens of <a href="http://archive.nepalitimes.com/news.php?id=2498#.Yc5xVy2B2t8" target="_blank" rel="noopener noreferrer">brick kilns</a> were spewing out smoke and steam into the city’s air (photo).The rain had washed down suspended particles, but the brick kilns were pumping more smoke into the air we breathe. There have been attempts to relocate brick kilns away from the densely-populated capital, but political patronage means owners are still fouling the air.After the 2015 earthquake damaged most of the Valley’s brick factories, <a href="http://archive.nepalitimes.com/article/nation/brick-factories-still-using-old-polluting-technology,2078" target="_blank" rel="noopener noreferrer">some adopted cleaner technology</a> to reduce emissions. Public pressure and urban growth then pushed most brick factories to the city’s fringes, and they are now  concentrated around Bhaktapur – most of those in the photograph are traditional dirty chimneys.After two years of forced closure during the pandemic, the brick kilns are once more working overtime to fill a backlog of demand from builders. But with politicians bogged down in power struggles, local leaders are too distracted to address the pandemic and pollution crises – both of which affect the human respiratory system.In a public opinion poll in this newspaper just before the 2017 elections, most respondents said <a href="https://www.nepalitimes.com/banner/dirty-politics-dirty-air/" target="_blank" rel="noopener noreferrer">air pollution</a> topped their list of concerns. Pollution has gotten worse since then, but it is unlikely that dirty air will figure in election speeches in 2022.“We have cleaner options like <a href="https://archive.nepalitimes.com/article/nation/earth-bricks-for-cleaner-and-healthier-kathmandu,4161" target="_blank" rel="noopener noreferrer">interlocking earth bricks</a>, so we just need public pressure to make it an election issue,” says environmentalist Bhushan Tuladhar.A pre-pandemic research showed that 40% of suspended particulates in Kathmandu’s air was from brick kilns, 30% from vehicular emissions, and 20% from open burning of trash and biomass. With the exponential increase in cars and motorcycles, the concentration of vehicular pollution at street level is now 70%.“<a style="letter-spacing: 0.01em;" href="https://www.nepalitimes.com/banner/breathing-is-hazardous-to-health/" target="_blank" rel="noopener noreferrer">Hazardous pollution levels</a> in winter have become the norm, yet the government is not doing much to control it,” says Shilshila Acharya of the Avni Centre for Sustainability. “The public should demand action from our leaders.”Although public awareness about <a href="https://www.nepalitimes.com/banner/how-weather-elevates-air-pollution-in-kathmandu/" target="_blank" rel="noopener noreferrer">air pollution</a> is at an all time high, it has not translated into action by municipalities or the federal government – even though in a democracy elections would be the way to force accountability from public officials.Says Tuladhar: “Campaigning in 2022 for elections, particularly for local government, will give us a platform to build political will to reduce air pollution. People have to be outraged, and the good news is that we have some young and educated leaders taking the lead.”In 2019, <a href="https://www.nepalitimes.com/banner/nepal-is-going-up-in-smoke/" target="_blank" rel="noopener noreferrer">air pollution</a> resulted in the deaths of 42,100 Nepalis, according to one research. Many more were indirectly affected. Vehicular emission, garbage and agricultural residue burning and brick kilns were the main sources of toxic ambient air.Besides shifting to cleaner and greener brick-making technology, controlling garbage burning, and a rapid transition to electric vehicles with government investment in electric mass transit, would be steps that would quickly improve air quality in Kathmandu.Air pollution is leading to the <a href="https://www.nepalitimes.com/latest/double-whammy-air-pollution-and-covid-19/" target="_blank" rel="noopener noreferrer">premature death of Kathmandu’s citizens</a>. It has a huge impact on the economy. The solution is political, and elected officials need to respond to the crisis.Adds Shilshila Acharya: “Politicians as always are big on promises but we demand that they first protect our health by cleaning up the air we breathe. It is a basic right guaranteed by the Constitution. Don't talk about more grandiose plans, just clean up our air first.”

In addition, peak season mean 8-hr ozone concentration should not exceed 60 kg/m3. The 2005 guideline values for PM2 and NO2 were, 10kg/m3 and 40 kg/m3 respectively, with no recommendation for long-term suspended particles and ozone concentrations.Environmentalist Bhushan Tuladhar immediately took to twitter to respond to the new recommended standard for air quality: ‘The WHO just released its new air quality guidelines which have halved the guideline value for annual average PM2.5 in ambient air. This means Kathmandu, which had annual PM2.5 levels that were about five times higher than the WHO guidelines now have pollution levels that are 10 fold higher.’The new standards are ambitious and reflect the large impact of <a href="https://www.nepalitimes.com/editorial/polluted-politics/" target="_blank" rel="noopener noreferrer">air pollution</a> on public health, and experts hope that it will influence air quality policy across the globe. They recommend bold action to clean up the air at all levels and across all sectors such as transport, energy, industry, agriculture and residential.“Air pollution is a major global public health threat that causes a range of adverse health effects, even at the lowest observable concentrations. The updated guidelines offer a wake-up call, to reconsider current air quality legislation and regulations,” noted a joint statement released by the International Society for Environmental Epidemiology (ISEE) with the European Respiratory Society following the revised guidelines.It adds: “There is ample evidence to strongly support government action to reduce air pollution and address climate change simultaneously. But the most important message is that each reduction in the outdoor concentrations of key air pollutants brings health benefits to the surrounding population, even in places which already have low pollution concentrations.”Additionally, most jurisdictions with <a href="https://www.nepalitimes.com/here-now/solution-to-pollution/" target="_blank" rel="noopener noreferrer">clean air</a> regulations have relied on fixed limit values with little incentive to further reduce air pollution levels once compliance with the limit value is achieved. Given the evidence that health effects occur down to very low concentration levels, future clean air policies must include incentives for progressive lowering of exposures of the entire population, thereby improving health for all.The new <a href="https://www.nepalitimes.com/here-now/how-transboundary-haze-affects-nepal/" target="_blank" rel="noopener noreferrer">air quality</a> guidelines are not legally binding however but experts believe can represent a turning point in the way we approach air pollution globally, and in particular, South Asia where the air pollution levels are consistently high and the health burden is stark.“The new guidelines offer a benchmark for South Asian cities and countries to plan their air quality agenda. This will bring renewed interest in the topic and create an opportunity to push for stronger action,” says Pallavi Pant of Health Effects Institute based in Boston.She adds: “We know where we’d like to get to, and the real discussion now should be focused on the basket of strategies and sectors we need to address.”Air pollution, indoors and outdoors, accounted for some 12% of all death in 2019. Air pollution currently ranks fourth among major risk factors for global disease and mortality, only behind <a href="https://www.nepalitimes.com/latest/why-do-so-many-nepalis-have-high-blood-pressure/" target="_blank" rel="noopener noreferrer">hypertension</a>, smoking and dietary factors.In terms of economic burden, the estimated global health-related external costs were $5 trillion in 2013 with an additional $225 billion in lost labour productivity as per the World Bank Group 2016.Here in Nepal, the new guidelines hardly made it to the news. Nepal doesn’t even have a minister for the environment because of a continued political stalemate.Successive governments in the recent past have made commitments to promote <a href="https://www.nepalitimes.com/here-now/cleaner-air-with-greener-buses/" target="_blank" rel="noopener noreferrer">electric vehicles and transport for clean air</a>, but they have done the opposite. Earlier this year in the budget, it reintroduced tax rebates. But only this week, Prime Minister Sher Bahadur Deuba’s government slashed taxes on the import of 10 or more diesel buses by new luxury hotels to 1%. It also cut by half the duty on petrol motorcycle assembly in Nepal.The Covid-19 pandemic and subsequent lockdowns over the last two years have shown people that the <a href="https://www.nepalitimes.com/banner/nepal-lockdown-proves-air-quality-can-be-improved/" target="_blank" rel="noopener noreferrer">goal of clean air can be achieved</a>, and it has become even more crucial at this point where the coronavirus cases are going down, vaccinations have picked up and businesses are reopening for the Dasain-Tihar festive season.“There is no shortcut to clean air, we need long-term policies that target major sources including transportation, use of wood/animal dung for cooking and heating, brick kilns, coal power plants, industries and waste burning,” adds Pant ,who is from India.She adds: “Access to clean energy for all is one key policy that can help reduce the burden of air pollution. It is also useful to keep in mind that air pollution is a multi-sectoral problem, and we must engage not just technical experts but also legal and policy experts, economists, healthcare workers and others in developing solutions.In the short term, especially as we approach the winter season, the government should ensure the public that <a href="https://www.nepalitimes.com/here-now/open-air/" target="_blank" rel="noopener noreferrer">air quality data</a> is accessible and understandable. With this information, the public can avoid outdoor activities during hours when the pollution is at its peak and reduce the prevalence of allergies and immediate respiratory illness.
