Pandemic: Less air pollution means thousands fewer die


PARIS, April 30, 2020 (BSS/AFP) – There will be 11,000 fewer deaths in
European countries under coronavirus lockdown due to a sharp drop in fossil
fuel pollution during April, according to research released Friday.

Measures to halt the spread of coronavirus have slowed the region’s
economies to a crawl, with coal-generated power falling by nearly 40 percent,
and oil consumption by a third.

“This will result in 11,000 avoided deaths from air pollution,” said lead
author Lauri Myllyvirta, senior analyst at the Centre for Research on Energy
and Clean Air (CREA).

Globally, oil use has declined by about the same amount, with drops in
coal consumption varying by region.

An unintended boon of shuttered factories and empty roads has been more
breathable air.

Levels of nitrogen dioxide (NO2) and small particle pollution known as
PM2.5 — both toxic by-products burning coal, oil and gas — fell 37 and 10
percent, respectively, according to the findings.

“The impacts are the same or bigger in many other parts of the world,”
Myllyvirta told AFP. “So we are looking at an even larger number of avoided

In China, for example, NO2 and PM2.5 levels declined by a 25 and 40
percent during the most stringent period of lockdown, with an even sharper
fall in Hubei Province, where the global pandemic began.

Air pollution shortens lives worldwide by nearly three years on average,
and causes 8.8 million premature deaths annually, according to a study last

The World Health Organization (WHO) calculates 4.2 million deaths, but has
underestimated the impact on cardiovascular disease, recent research has

Worst-hit is Asia, where average lifespan is cut 4.1 years in China, 3.9
years in India, and 3.8 years in Pakistan.

In Europe, life expectancy is shortened by eight months.

“Our analysis highlights tremendous benefits for public health and quality
of life that could be achieved by rapidly reducing fossil fuels in a
sustained and sustainable way,” Myllyvirta said.

– Pollution and COVID-19 – The happenstance evidence that less air
pollution saves lives should guide governments deciding on how to reboot
their economies, noted Maria Neira, the WHO’s director for Environmental and
Social Determinants of Health.

“When we eventually take off our face masks, we want to keep breathing
clean air,” she said, commenting on the findings.

“If we truly care about the health of our communities, countries and
global commons, we must find ways of powering the planet without relying on
fossil fuels.”

Compared to other causes of premature death, air pollution worldwide kills
19 times more people each year than malaria, nine times more than HIV/AIDS,
and three times more than alcohol.

Another study comparing more than 3,000 US counties, meanwhile, found that
PM 2.5 pollution is directly linked with higher COVID-19 death rates.

One extra micron per cubic metre corresponded to a 15 percent jump in
COVID-19 mortality, researchers at the Harvard University T.H. Chan School of
Public Health reported earlier this month.

The results “suggest that long-term exposure to air pollution increases
vulnerability to experiencing the most severe Covid-19 outcomes,” they wrote.

PM 2.5 particles penetrate deep into the lungs and enter the bloodstream,
causing cardiovascular respiratory problems.

In 2013, the WHO classified it as a cancer-causing agent.

In India’s Uttar Pradesh — home to 200 million — small particle
pollution by itself slashes life expectancy by 8.5 years, while in China’s
Hebei Province (population 74 million) the shortfall is nearly six years,
according to the Air Quality Life Index, developed by researchers at the
Energy Policy Institute of Chicago.

All but two percent of China’s cities exceeded WHO guidelines for PM2.5
levels, while 53 percent exceeded less stringent national safety limits.

The UN says PM2.5 density should not top 25 microgrammes per cubic metre
(25 mcg/m3) of air in any 24-hour period. China has set the bar at 35 mcg/m3.

emissions to data on the damages to health linked to exposure to air
