The global burden of disease associated with air pollution exposure exacts a massive toll on human health worldwide: exposure to air pollution is estimated to cause millions of deaths and lost years of healthy life annually. The burden of disease attributable to air pollution is now estimated to be ...on a par with other major global health risks such as unhealthy diet and tobacco smoking, and air pollution is now recognized as the single biggest environmental threat to human health.

This document summarizes several air quality measurement and modelling methods that can be used to estimate ground-level air pollutant concentrations and presents multiple approaches to monitoring ambient air pollution at different spatial and temporal scales. These methods are crucial for estimatin...g population exposures, which can be defined as the product of the pollutant concentration and the time over which a person is in contact with this pollutant.

Almost the entire Rwandan population (98.5%) relies on polluting fuels, particularly firewood and charcoal, for cooking. Access to clean energy such as electricity is still limited. In 2022, 70% of the population lived in towns and villages that have electricity – 49% from the national grid and 21...% from off-grid (mainly solar) systems. When access is defined as connection and use of households to electricity, an estimated 47% of households had access in 2020, representing 86% of the urban population but only 38% of the rural population.

WHO Air Quality Guidelines set goals to protect millions of lives from air pollution
UNCTAD sets out actions to support least developed countries in the global low-carbon transition
New report says COP27 is an opportunity to accelerate action to achieve mutually beneficial climate and development goals in the world's most vulnerable countries.
This report provides an overview of air pollution levels and associated health impacts in cities around the world. Since urban areas are often hotspots for poor air quality, city-level data can help to inform targeted efforts to curb urban air pollution and improve public health. This report draws o...n data from the Global Burden of Disease project and from peer-reviewed analyses led by Susan Anenberg of the George Washington University.

During the first year of the Covid-19 pandemic, the world’s economy slowed. Yet, the global annual average particulate pollution (PM2.5) was largely unchanged from 2019 levels. At the same time, growing evidence shows air pollution—even when experienced at very low levels—hurts human health. T...his recently led the World Health Organization (WHO) to revise its guideline for what it considers a safe level of exposure of particulate pollution, bringing most of the world—97.3 percent of the global population—into the unsafe zone. The AQLI finds that particulate air pollution takes 2.2 years off global average life expectancy, or a combined 17 billion life-years, relative to a world that met the WHO guideline. This impact on life expectancy is comparable to that of smoking, more than three times that of alcohol use and unsafe water, six times that of HIV/AIDS, and 89 times that of conflict and terrorism.

India is the world’s second most polluted country. Air pollution shortens average Indian life expectancy by 5 years,
relative to what it would be if the World Health Organization (WHO) guideline fine particulate pollution (PM2.5) of 5 μg/m3 was met. Some areas of India fare much worse than avera...ge, with air pollution shortening lives by almost 10
years in the National Capital Territory of Delhi, the most polluted city in the world.

In Central and West Africa, regions together comprising 27 countries and 605 million people, the average person is exposed to particulate pollution levels that are more than 4 times the World Health Organization’s (WHO) guideline of 5 μg/m³1. If these particulate pollution levels persist, averag...e life expectancy in the regions would be 1.6 years lower, and a total of 971 million person-years would be lost, relative to if air quality met the WHO guideline. The Democratic Republic of the Congo, Rwanda and Burundi, are the top three most polluted countries in the region.

Bangladesh is the world’s most polluted country. Air pollution shortens the average Bangladeshi’s life expectancy by 6.9 years, relative to what it would be if the World Health Organization (WHO) guideline of 5 μg/m³ was met. Some areas of Bangladesh fare much worse than average, with air poll...ution shortening lives by nearly 9 years in Dhaka, the country’s most polluted city.

Nepal is the world’s third most polluted country. Air pollution shortens average Nepalese life expectancy by 4.1 years, relative to what it would be if the World Health Organization (WHO) guideline of 5 μg/m3 was met.1 The highest concentrations of air pollution are observed in Nepal’s southwes...tern districts, which share their borders with the highly-polluted Indo-Gangetic Plain of India. Here, residents stand to lose nearly 7 years of life expectancy.
