Fossil Fuel Air Pollution Linked To 1 In 5 Deaths Worldwide, New Harvard Study Finds

Eight, Nine, Ten Million

Findings of this research will likely amplify calls to rapidly transition off of oil, gas and coal for reasons beyond curbing climate change

Air pollution from burning fossil fuels caused 1 in 5 deaths worldwide in 2018, killing more than 8 million+ people, according to Harvard University research published (Feb. 2021) in the 'Environmental Research Journal'.

The finding, based on new models that use atmospheric chemistry, significantly increased the previous estimates for deaths linked to tiny particles of burned carbon that lodge in soft lung tissue and cause respiratory diseases, trigger asthma attacks, and cloud cities with smog.

A recent prior estimate from the worldโ€™s largest and most comprehensive study of global deaths, known as the 'Global Burden of Disease Study', reported the total lives lost to outdoor airborne particulate matter โ€• which includes not only fossil fuel pollution, but also dust, wildfire smoke and burning crop fields โ€• at 4.2 million per year.

The new Harvard research shows nearly double that total from fossil fuel pollution alone, with the highest concentrations of fossil fuel-related deaths in regions with some of the most populous cities, where combustion-engine automobiles, fuel-heated buildings and sprawling power plants abound. Those regions include eastern North America, Europe and Southeast Asia...

Global implications as 90% of people breathe dirty air

Tiny air pollution particles have been revealed in the brain stems of young people and are intimately associated with molecular damage linked to Alzheimerโ€™s and Parkinsonโ€™s disease

Nanoparticles... linked to neurodegenerative diseases... more studies needed to study neuropathology of the brain stem

Neurotoxicants... 'metal rich nanoparticles... matched the shape and chemical composition of particles produced by traffic, through combustion and braking friction'

The Great Challenge: Air Pollution Impacts on Health from Childhood to Old Age


Report: Toxic air will shorten children's lives by 20 months

Global air pollution crisis is taking its greatest toll on children in South Asia

93 percent of the worldโ€™s children breathe polluted air each day

Nearly 2 billion children โ€“ about 93 percent of the worldโ€™s children under the age of 15 โ€“ breathe toxic, putrid air thatโ€™s so polluted it puts their health and well-being at serious risk, according to a new report by the World Health Organization.

Many of the children die: The United Nations' World Health Organization (WHO) estimates 600,000 children died in 2016 from lower respiratory infections caused by dirty air.

โ€œPolluted air is poisoning millions of children and ruining their lives,โ€ said Dr. Tedros Adhanom Ghebreyesus, director-general of the WHO. โ€œThis is inexcusable. Every child should be able to breathe clean air so they can grow and fulfill their full potential.โ€

Air pollution can affect children's cognitive ability and can also trigger asthma as well as cancer. Children who have been exposed to high levels of air pollution may be at greater risk for chronic illnesses such as cardiovascular disease later in life...

Off-the-chart air pollution in Delhi

Devastating, debilitating, deadly

Delhi Disaster


The Delhi air quality index, or AQI, reached as high as 858 at some areas in New Delhi at 6.30 a.m. on Monday after breaching 1,000 over the weekend, according to website AirVisual, which monitors air pollution around the world. Readings above 300 are considered hazardous and anything below 50 is the safe level.

The level of carcinogenic pollutants, which increases risk of stroke, heart disease and lung cancer, in New Delhiโ€™s air was almost six times the reading in Beijing, where air quality has seen a considerable improvement over the past years.

โ€œA child born yesterday in Delhi would have smoked 40-50 cigarettes on the first day of his or her life,โ€ said Arvind Kumar, a lung surgeon at the Sir Ganga Ram Hospital in Delhi and founder of the Lung Care Foundation. โ€œA silent damage is occurring inside our body.โ€

India, home to 10 cities with the worldโ€™s worst air quality, has been struggling to contain this annual catastrophe that killed an estimated 1.24 million citizens in 2017...

Harnessing Real Time Data to Combat Air Pollution



Tracking Ozone-Smog in U.S. Cities


Detecting pollution of shipping lanes and individual ships from space

For the first time ever, scientists using data from @CopernicusEU #Sentinel5P were able to detect nitrogen dioxide plumes from individual ships from space.

A past study estimated that shipping emissions are globally responsible for around 400 000 premature deaths from lung cancer and cardiovascular disease, and 14 million childhood asthma cases each year.

For this reason, during the past decade, efforts to develop international shipping emission regulations have been underway. Since January 2020, the maximum sulphur dioxide content of ship fuels was globally reduced to 0.5% (down from 3.5%) in an effort to reduce air pollution and to protect health and the environment. It is expected that the nitrogen dioxide emissions from shipping will also become restricted during the coming years.

Monitoring ships to comply with these regulations is still an unresolved issue. The open ocean covers vast areas, with limited or no capacity to perform local checks. This is where satellites, such as the Copernicus Sentinel-5P satellite, come in...

Claus Zehner, ESAโ€™s Sentinel-5P Mission Manager, commented, โ€œWe think that these new results demonstrate exciting possibilities for the monitoring of ship emissions in support of environmental regulation from space. Future planned satellite missions with improved spatial resolution, for example the Copernicus Anthropogenic Carbon Dioxide Monitoring satellites, should allow for the better characterisation of nitrogen dioxide ship emission plumes and, possibly, detection of smaller ship plumes.โ€

People in the UK are 64 times as likely to die of air pollution as those in Sweden and twice as likely as those in the US, figures from the World Health Organisation reveal.

"It is deeply tragic that around 3 million lives are cut short worldwide because the air we breathe is dirty and polluted. In the UK, air pollution is a public health crisis hitting our most vulnerable the hardest โ€“ our children, people with a lung condition and the elderly."


One Day's Toxic Air News Pulled from the Headlines










Decades ago Mexico City's air pollution was so poor, birds would fall out of the sky -- dead. Locals said living there was like smoking two packs of cigarettes a day, according to one report. In response, Mexico City took several steps to try to improve air quality including restricting driving one or two days during the weekdays. The program has had negligible results.

What Can Be Done

Making Progress: Models of Environmental Initiatives that Have Made a Difference

GreenPolicy360 siterunner: Los Angeles, the 'worst in the world' in air quality in the 1950s. Now LA and California are 'out in front' of clean air and environmental initiatives, providing models of what can be done nationally and internationally.

California political leaders Jerry Brown and George Brown, out in front with a first-generation legislative regulation of air pollution

Governor Jerry Brown
George E. Brown Jr


From the Institute for Governance & Sustainable Development


California / AB 1493, Pavley. Vehicular emissions: greenhouse gases

...a model of green legislative best practices

...the "Pavley Law"', first legislation in the world to regulate greenhouse gas emissions of passenger vehicles... these visionary California environmental protection laws/regulations became model air quality / air pollution legislation and were ultimately adopted by the United States as the national standard.



Jerry Brown (2015): "California has this history that really derives from the experience of smog in the Los Angeles Basin, and the response to that over many administrations has led to where we are today. As a matter of fact the standards that were established under the so-called Pavley Law, 'the first legislation in the world to regulate greenhouse gas emissions of passenger vehicles, were ultimately adopted by the United States as the national standard'".
Air Resources Board - Model Regulations / 'Green Best Practices'
ARB - Background

"Today Los Angeles has ten times as many cars as it did in the 50s, and the air is 95 percent cleaner. Thatโ€™s a pretty dramatic move, one that countries like China and India are taking notice of."

"So weโ€™ve had that history. As far as peopleโ€™s attitudes I would say that there is a strong preference for favoring policies that nurture the environment as oppose to those that disrupt them."

"But if you dig deeper into the use of things or creature comforts, I donโ€™t think weโ€™ve attained the level of enlightenment that Pope Francis is calling for."

Breathing Poison

โ€ข - Breathing Poison


Smog, ground-level ozone, causes a host of respiratory consequences, ranging from coughing, wheezing and throat irritation, to asthma, increased risk of infection, and permanent damage to lung tissue.


Via the Guardian, 2016 / โ€œWe have a public health emergency in many countries from pollution. Itโ€™s dramatic, one of the biggest problems we are facing globally, with horrible future costs to society,โ€ said Maria Neira, head of public health at the World Health Organization. โ€œAir pollution leads to chronic diseases which require hospital space. Before, we knew that pollution was responsible for diseases like pneumonia and asthma. Now we know that it leads to bloodstream, heart and cardiovascular diseases, too โ€“ even dementia. We are storing up problems. These are chronic diseases that require hospital beds. The cost will be enormous.โ€

  • The toxic haze blanketing cities could be clearly seen last week from the international space station.
  • Poor air quality is killing millions and threatening to overwhelm health services across the globe.
  • With nearly 1.4 million deaths a year, China has the most air pollution fatalities, followed by India with 645,000 and Pakistan with 110,000.
  • The latest scientific research, published in the journal Nature, suggests that air pollution now kills more people a year than malaria and HIV combined, and in many countries accounts for roughly 10 times more deaths than road accidents.
  • According to the WHO, air quality is deteriorating around the world to the point where only one in eight people live in cities that meet recommended air pollution levels.
  • "We are only just learning about the scale of the toxicity of coal and diesel... This is a deep, deep problem."
