Situation
and Trends

2


Ambient Air
Pollution 
Air pollution is a major environmental issue
affecting people across the world. According
to the World Health Organisation (WHO),
more than 2 million people worldwide die
every year from air pollution.
● the population of Asia and the Pacific is
among the most highly exposed to PM2.5
in the world.

Indoor Air
Pollution
● Globally, the number of annual
deaths from indoor air pollution has
fallen by more than 1 million since
1990


● This means that despite continued
population growth in recent
decades, the total number of deaths
from indoor air pollution has still
declined.

Health affected
by air pollution
● Fewer than 8 percent of the region’s people
are exposed to levels of air pollution that
do not pose a significant risk to their health
according to the World Health Organization
(WHO) Guideline. 
● WHO estimates that in 2016, some 58% of
outdoor air pollution-related premature
deaths were due to ischaemic heart
disease and strokes

Causes



Ambient Air
Pollution 
● Common sources of air pollution
are emissions caused by
combustion processes from motor
vehicles, solid fuel burning and
industry






Urbanization source
Stationary Sources
Mobile Sources 
Rural Area Sources 
Marine Emissions

Household Air
Pollution 
● Air pollution is now considered the world's
biggest environmental health threat. Half of
the world's population has no access to
clean fuels or resources, 9 out of 10 people
are inhaling polluted air, and up to 7 million
people are killed each year because of air
pollution.

● The impact of air pollution on human health
is increasingly concerned

Valuation of air pollution’s effect
on healthcare expenditure
● The analysis involved two steps:

○ Measure the reductions in PM2.5 and ozone
concentration levels throughout the area for our
air quality improvement scenario.
○ Quantify potential spending reductions 

11






China managed to calculate that for every
10 μg/m3 decrease in PM2.5 concentration,
a reduction of 9 billion $ in healthcare
expenditure for air pollution will occur. 



In order to convert this data into the Asia’s
healthcare expenditure for air pollution, we
will have 2 assumptions.

in order to reduce 10 μg/m3 in PM2.5
concentration, Asia as a whole will
need at least 9 billion $.

at any level, a 10 μg/m3 decrease in
PM2.5 concentration will always results
in  a reduction of 9 billion $ in
healthcare expenditure for air pollution
and vice versa.

12


From the table above, we can calculate the mean level of PM2.5 concentration in Asia is about 21,56
μg/m3. Therefore, follow our function above, we come to conclusion that the healthcare expenditure
for air pollution in Asia is at least 19,5 billion $.
