As the globe gets hotter and more crowded, our engines continue to pump out muddied emissions, and half the world has no access to clean fuels or technologies (e.g. stoves, lamps), the very air we breathe is growing dangerously polluted: nine out of x people now breathe polluted air, which kills vii million people every year.

The wellness furnishings of air pollution are serious – 1 3rd of deaths from stroke, lung cancer and center disease are due to air pollution. This is having an equivalent effect to that of smoking tobacco, and much higher than, say, the effects of eating too much salt.

Air pollution is hard to escape, no thing how rich an area you live in. It is all effectually usa. Microscopic pollutants in the air can sideslip by our body'southward defences, penetrating deep into our respiratory and circulatory organisation, damaging our lungs, eye and encephalon.

Air pollution is closely linked to climate modify - the chief driver of climatic change is fossil fuel combustion which is too a major correspondent to air pollution - and efforts to mitigate one can improve the other. This month, the Un Intergovernmental Panel on Climate Change warned that coal-fired electricity must end by 2050 if we are to limit global warming rises to 1.5C. If not, we may encounter a major climate crunch in just xx years.

Coming together the goals of the Paris Agreement to combat climate change could salve about a million lives a year worldwide by 2050 through reductions in air pollution alone. The economic benefits from tackling air pollution are meaning: in the fifteen countries that emit the most greenhouse gas emissions, the wellness impacts of air pollution are estimated to cost more 4% of their GDP.

"The true toll of climatic change is felt in our hospitals and in our lungs. The health burden of polluting energy sources is now so loftier, that moving to cleaner and more sustainable choices for energy supply, send and food systems effectively pays for itself," says Dr Maria Neira, WHO Director of Public Health, Environmental and Social Determinants of Health.

The lack of visible smog is no indication that the air is healthy. Beyond the world, both cities and villages are seeing toxic pollutants in the air exceed the average annual values recommended by WHO'due south air quality guidelines. To assistance people better empathize just how polluted the air is where they alive, the WHO, Un Surround and the Climate and Make clean Air Coalition'due south Exhale Life entrada adult an online pollution meter.

This year, WHO and partners are convening the first Global Conference on Air Pollution and Wellness in Geneva on 29 Oct – one November to rally the world towards major commitments to fight this problem. The briefing volition heighten awareness of this growing public wellness challenge and share data and tools on the wellness risks of air pollution and its interventions.

This briefing will showcase some of WHO's work on air pollution, including the findings of its Global Platform on Air Quality and Health. This platform whose various membership includes researchers, civil society, UN agencies and other partner institutions reviews the information on air quality and health. For case, the platform is working on techniques to more accurately attribute air pollution coming from unlike sources of pollution. It is also working on improving estimates of air quality by combining the data from various air quality monitoring networks, atmospheric modelling and satellite remote sensing.

Critical issues at the first Global Conference on Air Pollution and Health

Air quality monitoring → Air quality monitoring in low- and middle-income countries needs to be strengthened, especially in areas close to hospitals, schools, and workplaces. Low-cost sensors and other new technologies can expand air quality monitoring and forecasting to areas that are currently underserved. New protocols and standards are needed to guide the effective use and estimation of data produced by low-cost sensors in citizen science and other applications.

Health sector emissions → Access to reliable and sustainable energy in healthcare facilities is essential to achieve the goal of universal health coverage. On-site renewable energy generation in healthcare facilities tin can improve access to healthcare services, especially in rural, developing earth settings. In adult countries, hospitals are among the nigh energy-intensive buildings. Past reducing its ain carbon footprint, the health sector can evidence how climate change mitigation produces concrete health benefits.

Equipping national health workforces → National wellness workforces must be capable of dealing with the immediate impacts of air pollution on the health of populations, and to inform policymakers to undertake preventive action to reduce the air pollution-related affliction burden. There are currently few grooming programmes on air pollution and its health effects, and petty related data, in public health teaching.

Children's health → Globally, 93% of children nether eighteen alive with air pollution levels to a higher place WHO guidelines. Air pollution causes over half of all child deaths from astute lower respiratory infection in children under five years in lower middle income countries. Air pollution exposure is linked to a wide range of adverse health outcomes in children, including infant mortality, asthma, neurodevelopmental disorders, and babyhood cancers. Past "prescribing" clean air for children, policymakers can protect them from the lifelong effects of air pollution exposure.

Access to clean household energy → Clean household energy access must move higher on the global free energy, wellness and climate agendas. Household air pollution is 1 of the globe'southward single biggest environmental health take chances, and a meaning source of climate-warming pollution. To reach SDG 7 targets for universal access to modern energy, iii billion people must gain access to clean cooking solutions, and i billion must gain access to electricity, by 2030. The current pace of progress mains too slow.

Climate change → Air pollution is the greatest environmental adventure to health of our fourth dimension, and climate change is the greatest public health threat of the 21st century. Burning fossil fuels is the primary source of both climate-warming emissions and health-damaging air pollution. Reducing emissions of curt-lived climate pollutants can generate immediate benefits for health and ho-hum climatic change Actions to reduce both greenhouse gas emissions and short-lived climate pollutants are also measures to protect public health now and in the future.

Noncommunicable diseases → Air pollution is the 2d leading cause of noncommunicable diseases, such as stroke, cancer and centre affliction, which are on the rise worldwide. In many countries, such diseases can only be significantly reduced by improving air quality. Mainstreaming air pollution reduction into policies to combat noncommunicable diseases leads to multiple benefits for the surroundings, economic system and health.

Outdoor workers → Outdoor workers, including agricultural, structure or waste drove workers, and traffic police, are peculiarly vulnerable to ambient air pollution; at least 1.ii billion people work outdoors virtually of the time. In add-on to breathing polluted air, such workers are oft exposed to other ecology risks, such as heat and cold, heavy rain, and wind as well as solar UV and allergenic pollens.

There are ii main types of air pollution – ambient air pollution (outdoor pollution) and household (or indoor) air pollution refers to pollution generated by household combustion of fuels (caused past burning fuel such as coal, forest or kerosene) using open fires or bones stoves in poorly ventilated spaces. Both indoor and outdoor air pollution can contribute to each other, as air moves from inside buildings to the outside, and vice versa.

Household air pollution kills 4 million people a year and tends to affect countries in Africa and Asia, where polluting fuels and technologies are used every twenty-four hours particularly at home for cooking, heating and lighting. Women and children, who tend to spend more fourth dimension indoors, are affected the most.

The chief pollutants: are (ane) particulate affair, a mix of solid and liquid aerosol arising mainly from fuel combustion and road traffic; (2) nitrogen dioxide from road traffic or indoor gas cookers; (3) sulphur dioxide from burning fossil fuels; and (four) ozone at ground level, caused past the reaction of sunlight with pollutants from vehicle emissions. The pollutant that affects people the virtually is particulate affair (often abbreviated to PM and used as a measure for air pollution).

5 ways to limit breathing polluted air

While particles with a diameter of 10 microns or less, (≤ PM10) tin can penetrate and lodge deep inside the lungs, the fifty-fifty more than wellness-damaging particles are those with a bore of 2.five microns or less, (≤ PM2.5). These particles are so modest that lx of them make up the width of a human being hair.

PM2.five tin penetrate the lung barrier and enter the blood system. They can increase the gamble of heart and respiratory diseases, as well as lung cancer.

Ozone is a major factor in causing asthma (or making it worse), and nitrogen dioxide and sulfur dioxide can as well cause asthma, bronchial symptoms, lung inflammation and reduced lung function.

Then how polluted can air be before information technology starts to bear upon our health? For PM2.v, WHO guidelines say the maximum safe level is an annual average concentration of 10 μg/m³ or less. To encourage cities to reduce air pollution, even if they are unable to meet the ideal safe levels, WHO has gear up iii interim targets for cities. These are: fifteen μg/m³ (interim target iii); 25 μg/chiliad³ (interim target 2); 35 μg/m³ (acting target 1). Many cities are at present exceeding the very upper level of interim target i.

Air pollution has a disastrous result on children. Worldwide, up to 14% of children aged five – 18 years have asthma relating to factors including air pollution. Every year, 543 000 children* younger than 5 years die of respiratory disease linked to air pollution. Air pollution is also linked to childhood cancers. Pregnant women are exposed to air pollution, information technology tin can bear upon fetal brain growth. Air pollution is also linked to cerebral damage in both children and adults.

_{*Number updated to reverberate new numbers published by WHO on 29 Oct 2022}

As well equally affecting our health, pollutants in the air are as well causing long-term environmental damage by driving climate change, itself a major threat to health and well-being.

This month, the Un Intergovernmental Panel on Climate change warned that coal-fired electricity must end by 2050 if we are to limit global warming rises to 1.5C. If not, we may see a major climate crisis in just 20 years.

The briefing next week volition phone call for urgent activity, seeking agreement on a target for reducing deaths from air pollution.

WHO and partners such every bit UN Surroundings are developing ways to support countries. For example, WHO is developing a toolkit (the Clean Household Energy Solutions Toolkit, Breast) to assist countries implement WHO'south recommendations on household fuel combustion and to develop policies to expand clean household energy apply.

BreatheLife – a global entrada for make clean air, headed by WHO, the Climate and Clean Air Coalition, and UN Surroundings – is mobilizing communities to reduce the bear upon of air pollution in cities, regions and countries, currently reaching around 97 1000000 people.

Clean air interventions will be a focus of the conference. Affordable strategies be to reduce emissions from free energy, transport, waste direction, housing and industrial sectors. These interventions ofttimes carry other benefits like reduced traffic and noise, increased concrete activity and better land apply – all of which contribute to improving health and well-being. The conference will nowadays activities and results from the ongoing work of the WHO's Urban Health Initiative focused on supporting cities with the data, tools and capacity to select, implement and track 'clean and healthy' policies at the city level. Improve air quality volition benefit all of usa, everywhere.
