well good morning everybody it's my very big pleasure to be here in geneva ah and talk about the
topic that is close to my heart is you have heard in the teens morgan twenty five years
oh it is very strange if you imagine that i grew up here in double was
um how can one occupied the whole life with air pollution there is almost no air pollution up there
a particular not today anymore but that's how life sometimes goal was and if you ask me
i still do remember one thing when i was a little boy in double was
actually there were still such cards as you see here i remember whenever a
coast man came when i was walking home up to the other
uh and put to mean that clout i felt very embarrassed and i closed bibles
um as a boy look like h. six or so looking back that was actually
not a bad idea and i didn't have filters unfortunately so i just closed my nose
ah well this is my biography here if you look might i agree from
the exposure to air pollution perspective that's what happened in my life
i started pretty good and moved up and up to scale of air pollution ending a couple of
years in barcelona and then i thought lied now it's enough and i returned back to boston
um as you do see apostle its ranking pretty well and actually even lower
today than a few years ago and i will come back to that
so what i would like to do with you i wanna walk you through
these uh they're important cycle which we will call the air policy
making cycle where we start with the problem yeah pollution exposure the
red box moving to the question what the health effects are
we don't stop there we wanna know what is the impact in the
population before asking us about treatment and as you have heard originally
i was a fixation and of course disease take evidence based maybe seen
type of cycle uh also used in the field of medicine
so let me walk through all these corners and uh i will start was to a
air pollution exposure and just emphasise one very important message to all of you
yeah pollution is march board and particles the p. and the particulate
matter i do know you are all very interested in particles
um given your interest in filters but that is much more and we should not forget about that
it is a very complex mixture of gases of all that type of particles and
if you even look at the park because there is more than just
particles they can be distributed state can be described i size
number mass blackness succeeded properties in many many other
aspects characteristics and uh of course even if you look to buy this size
oh you would probably agree there must be something with the size no matter which part because you choose even
if you look this comparison your i would assume nobody uh would argue that
viruses are not important not nobody would argue that bacteria are not important
that if you have your hair in this soup you would agree with
me that even to hear the size of particles has some relevance
so this is the mixture of air pollution is absolutely crucial
to measure to correct the rise what's going on
the knee here before asking us about questions of its
health effects this is just the example from switzerland
this is the monitoring network of to swiss federal authority in addition
we have many monitors around by the county auditory piece
that is nothing else think actor rising air pollution and of course particles
uh are characterised on filters uh which uh measure the mass
um wait a in part of particle mass of different sizes
well this is switzerland let me walk now a little bit further on the glow
up i'm from this we talk about because institute it's very important that we
actually carry out a global message and not just a local one this
is the very unfortunate picture off the monitoring situation around the clock
if africa for example would have an s. dance network
of monitoring stations like switzerland there would be some
sixty eight thousand monitoring stations distributed over does not and you see how terrible this look
so there's enormous inequity inequity is icky topic are that will go through all my talk
um if you for example goat to akron inaccurate colleagues of mine
have done a very nice started to i'm just stands
exposure to particles for example and other pollutants within the city of factor so what
they did they were just walking in the c. d. along a trail
uh not even long distance and they measured pollution and look at this
these are the callers highlighting the level of particles p. n. two point five particles
up to two point five my crummy present you see these range you could
walk no matter where in genie mind would never get such high levels in our
current depending on where you are on which corner of the c. d. you
are you can be exposed to extremely high levels of particles i think today
the level of particular yesterday and you knew i was around twenty years
so where do is the particle come from air pollution come from
they try to estimate the sources and you see these
diversity of sources in a city like macro this is totally
different from here many people are trash out burning trash
a traffic of course all over the world basically source of air pollution
of local pollution and general pollution but of wood and coal burning
in our crap it's relevant it's not relevant here and we are currently doing a study impair on another major
city with huge problems in air pollution so my p. h. d. student has done a lot of measurement
supported by the local authorities these days benzene benzene is not a big issue
here in geneva it is one as we have figured out in
in data so they're very very high levels of these very nasty carcinogen
of course the next step is to model their pollution so you don't
only measure today you can model air pollution for very large
areas based on a few measurements to understand that whole scale of
to distill she let me move to the house effects
so what does that mean air pollution effects on well i would distinguish too big domains
because the whole research and also it actually the the evaluation and valuation and
uh impact assessment if there's a cute defects and long term effects if you look into the acute effects
it's very clear what i mean was it these these are the effects
of today's er yesterday said pollution on my house today or tomorrow
so this is an immediate effect and i can tell you this is just one example
of two time series of data the time series of the blue line attests
in any seat in the word the reddish line or particle
concentrations on a daily level and there have been hundreds
probably so when even thousands of studies done all over the word and they always see and uh and
conclude this same as hard because as air pollution as an o. two when others go up
best rates go up it's about one to two percent for every ten micrograms per
cubic meter increase in the daily level of p. m. that mortality goes up
seen again and again of course this cannot be the only tells the story
if that was the only thing you would see would actually very much about this
data but there are many many many other studies that have shown of course
it's not only about they have some people will not not able to type a health problem they will
end up in the hospital the hospital iteration the rates go up as air pollution goes up
cardiovascular problems my cotton in functions go up as air pollution goes
up throw goes up every it's me out blot flopping
et cetera a lot of respiratory disease problems you're just increasing as a permission increase
well actually wary about a nice example of such a study this study
is pretty unique it has been done with this max so this is not
exactly invited in london to participate in the study they were invited to
more kinda hyde park i'm sure most of you know where to
hide parties you defer layer and the midst of london
they had also to work for two hours in the oxford street oxford
street to street canyon at that time still a lot of
a boss is actually diesel buses traffic a very very dense traffic
a very to the place compared to the hyde park so at the if
oxford street air pollutants wording that study period some three to six times
higher depending on which market you would measures so very high
level of air pollution compared to the hyde park and you see
here what they observed among other things if this magic hat
the last part of the long function which is normally if you walk out on
that exposure at oxford street is lost in long function was much more serious
then walking into hyde park and most surprisingly it would go
on and on and on unfortunately the experiments stopped up
to seven after seven hours because they did not anticipate that is consequences of this air pollution exposure would
go and last for so long so what does that mean for an asthmatic well and
that's my take walking through a place ah during rush hour like uh like to
uh oxford street and many others uh although the pro with the word it would
stuff they would feel reduction in their lawn function they may need more medication and it's
definitely not what you like to see it says rescission pneumonia patients with nasa
so let me move to the long term effects longterm effects what is that
well this is now the big question does it matter where i leaf
four years does it matter whether i'd grow up in the woods versus los angeles
lifetime exposure well having you all here in switzerland of course i have to mention uh one of their
famous worldwide famous studies initiated twenty five years ago almost thirty years ago
in switzerland this we start the on air pollution in long and heart disease
in about a led by professor nicole props that our institute in boston
the study is still all wrong going on and what you
see here is the map of switzerland colours of particles
and the eight centres that have participated and we have followed up these people over
the last thirty years now and uh followed up in measure to help us
and we have assigned stay home outdoor air pollution to everybody to
understand how this relates to all kinds of health problems
let me just show one single example over is well there are many out this but this
is a very interesting one because what we also measured his lawn function objectively measured
a measure of health and the most interesting fun factor of long
function easy does a very strong determinant of life expect
so it's not just about the health of the long but it is really a market of general helps
what we have seen is the loss of non function which is nothing else then the
speed of a chain getting older the loss of long function
depended on the home out the reportage so people living at the residential place with higher pollution
they have lost belong function faster than the with leaving clean the places and that's
good news for those who leave you clean the places and bad news for the others
let me move to another place where i have lived for a couple of years diseases angeles
a famous for air pollution research um this is a talk psychological studies my colleague from the u. c. l.
a. to have moved they're allowed to the skyway which is one of the spam is terrible places
half a million cars per day running so they have expose their mice to long
term exposure from the mice perspective that is a long term exposure model
and the mesh shirts the development of after school roses and they were inhaling the air from the
highway of course some mice would get filters to hear others would only received fine particles
other mice with only received the altar find that what you see here is these particles in
particular also the outer finds table cause really related to the development of adaptors to roses
the classification of arteries the stiffness the thickness of arteries so this is
a very important talks ecological finding and actually while i
was in los angeles i've initiated research line
on investigating the same inhale men's so why is this a possible to do in humans
ah well in a very nice feature about as close as is shown in this graph here so up here you have a normal
artery and the more you go down to more see we're is the actors for roses what you see here is development
happens mostly in the will of the artery and arteries corrode take how
to fight our to get sicker and sicker and stiffer and stiffer
and at the end of course down here there's a higher risk that
it will pop up and tell people suffer for example a cardiovascular
event like a marketing function so the thickness of the artery wall can be measured
non invasive fleas on a graphically and that is very nice so i have you start is uh in the
us and actually others have then followed as well and i shall we just one famous example from germany
this very nice hides next or study they have observed that the
sickness of the artery the stiffness of the article suffocation
depends on your home outdoor label of air pollution of particles
in two point five you see here it's arranging
in the range which is typical now also in switzerland so the more pollution you have the thicker are
the arteries and that means the more likely it
be steady develop actually cardiovascular diseases real diseases
um oh well cardiovascular diseases are the leading causes of moby dick
this on a global scale not only in the west
and of course people with these diseases they tends to also die earlier
the mortality life expectancy is the ultimate way of measuring the
effect of air pollution and there are many many studies
looking to stay metallic i just wanna emphasise one because it's one from europe
uh where we have also participated it is a huge one b. s. cape consort you mess
used a lot of studies including this we start is this apology study indeed
and we have looked into how people would die out of those school works or
would be used depending on the home out the label of air pollution
and guess what we have seen what others have seen in the u. s. cannot that other places with
every increase in the whole mouth or particle find particle concentrations
for five micrograms mortality would go up seven percent
and most interestingly because escape was such a huge studied either i it
to focus only on those people who lived in the cleanest place
which means people who left at the place of the residence with less than twenty micrograms per cubic
meter on the end will mean yeah so this is on a global scale this is low
more than two hundred thousand people and we have seen exactly the same associations which is one of the many
studies meanwhile actually show there is no threshold of no
effect the higher air pollution the more people stuff
well if you wanna go into summarising all the health effects i
can um advise you to reach for example these paper
uh this is somebody an overview on the adverse effects of air pollution there many others
might very last slide shows you the link to report that we have written
a few years ago so this is the ever longer and longer released of
health effects that have been shown to be related to and didn't approach
so you see this list is very long and you see that interesting actually
findings like diabetes disease only since a few years that people have
figured out that even diabetes metabolic diseases relate them to their pollution
including this we study on a present long disease has observed that so
this is very interesting we haven't thought about that twenty years ago
but meanwhile we understand much more also about the
many pathways that link air pollution with diseases
so one for example are inflammatory pass phrase inflammation and of course
it's important for many many chronic diseases and that's why these least gets longer and longer
and actually look smaller more similar to the least to be no since many years about the health effects of smoking
which is not a big surprise because in fact it's also combustion and
their toxic cans in the smoke of the tobacco are similar
to what you see in the n. b. in there with the only important difference is that if you smoke you expose yourself
many fold times higher than with n. b. c. at least in the west and how
well so this is what we can conclude there are many many effects now
described and you would see to quantify d. link between air pollution
and those effects but the question is of course is this important just is relevant
and you can imagine it reality like in all other signs in the last twenty for
five years you have made a huge progress in detecting smaller and smaller effects
so the question whether this is relevant or not is absolutely crucial
so how can you do that the question is what is the
burden of disease of mortality that is attributable to air pollution
and this is a question we actually half lounge to develop the methods in switzerland
uh a couple of well almost twenty years ago and very
interesting story in fact it was dismissed government to asked
us when we did this about this study what could be allowed tell us how important that these for switzerland
what is the impact of traffic related their pollution on the hell's
in switzerland light that they wanna know that in the nineties
they wanted to know that because switzerland tried to move
into that direction of internalise thing big external cost of pollution
so they wanted to change the transit she's of the heavy duty
traffic screw switzerland based on the consequences of that traffic
and they included costs related to air pollution many other factors related to trap
so he asked this question of course you need to know what's the impact we have developed this method
and these were the famous numbers that have travelled around the word
aboard and with what we anticipated yes some forty thousand
test every year on it to be double to air pollution at that time at least in austria france and switzerland
it must be a little bit less today but these methods that we have developed have actually
initially the encrypted size and finally people agreed that this is the way to do it and it's still
done today on a very global scale you see many many studies we have assessed the impact
very soon one most interesting one is the word bank report on the cost of
air pollution so if you can quantify the impact on hell's and mortality
with the help of economists you also can quantified related costs
and that's what uh the world bank recently date
e. p. a. in the u. s. and other agencies and as mentioned in switzerland they
have done that before and the us has concluded also already many years ago that
investment in clean air are very much worth because that then each of
polluted air on the health system is about fourteen times
larger than the costs of investing in clean airports
so word bank report what do they conclude
ninety three percent of the attributable problems
r. o. q. ring in the developing countries so that is a terrible
conclusion and shows again this incredible iniquity children on the five
our sixty times more likely to die from air pollution
in the lower income count to stand what they are in our uh accountancy
non health effect of air pollution are very serious economic development quality of
life productive labour goes down income goes down productivity is affected
and of course it makes in general cities lex attractive and
uh of course this has also implications even on tourism
so all this is the map from mortals as mentioned many
places lack measurements station so there has been models have
been developed on a global scale so you see here these
dark colours show you where the biggest problems are
that's the end will average of particles and gases the basis
of these cost assessment of the word bank report
so these iniquity is very clear and actually if you look into the global burden of disease
he did we look if you go to each and every county you would figure out that air
pollution and this is the combination of indoor and
outdoor which is all combustion is the leading
risk factor in all those counters and it's the second
leading the risk factors um in the other cultures
and the third leading risk factor again invisible and and as you see these these
all the global south is not is saying the rest encountering on that list
actually the word bank reports is in mining so they relate to damage and
relation to the gross domestic product and you see this is very serious like almost eight
percent of the g. d. p. is lost into air pollution in east asia specifics
um of course it's lower in europe but still substantial
and a south asia you see very very high
contribution of air pollution to the last two an economic loss in these counties
and you see here does bars compare the household indoor air pollution combustion
for cooking and the end in one and in some regions
of the world household is more important than others definitely
not like in europe of course the combustion indoors is not an issue uh on the other eleven one
so well i hope i've convinced you that the burden related to air pollution is
serious so i'll ways that that knows is it is time to talk about the treatment
what should we do and of course what we should do it's about all this
and yes i'm sure you wait to hear from me that it is about filters arm
filters yes i totally agree that play a role but i
want to highlight this message of temple ground in
she was a famous or she's a famous um veterinarian protector of animals
actually and she works a lot and lobbies a lot for autism
i think the sentence is important to put here people are always
looking for dissing a magic bullet it will totally change everything
but there is no single magic bullet and one emphasise that he
because in my field of a pollution i tell you
each and every pollutant each and every probably see each and every health effect has a low b.
oh so some people just talk about they are saying that you should single problem entity if that is
the magic bullet and they believe that is the solution a
disease that wrong concept i just show you one restart
to put that message in one single example in the context because the study has just come out last week
again a large courting taiwan have followed up people to look how they develop
lost in kidney function kidney diseases are very important as well and they
have shown that the whole outdoor air pollution is again associated with
the loss of kit a function that is kind of a new are finding it was not on my to do list before
but it was not everything not all types of pollution home outdoors they have seen a clear association
significant with p. m. ten and with the course fraction of particles
it was not related with the smallest for parking with p. two point five
or we stood at this is just one example or many others
well you can always say well wait a minute there is more work
then you're particle or you were gas or your wallet tiles many
pass the ways in fact and many pollutants combining different pathways of effect
a result ultimately in very complex diseases more beat it is
and that's true also given that we have many many sources
well i mean actually fit talk about diseases look at this why
why does it even make sense that for example particles
are not just black and white well if you look how what happens if we inhale a particle
that if these deep you should how these particles peep hand on depending on their size
and it's not black whites there is the distribution so you see in
the tall grass sick to position which for some diseases is important
uh has two peaks so the very small ones but also
the bigger once they are very well deposits down the
others are more efficiently exhaled and of course depending on where you deported part because there
are different mac mechanisms in well so this is not the black and white
uh effect and there is not a black and white if it's coming to sources
so if you combine all that effects the pollutants to sources of course
the policy cannot be a black and white and yes and no need
so what my real messages we talk about symphonies it's to see if any of clean apple we see
air pollution isn't orchestral of complex pollutants course
by many sources the health effects
are excellent orchestrated by many past wait you know there are also some
toxicologist of physicians to believe only in one passed away and if you don't show
the pollution being associated with that passed away they don't believe distorted no
biology is far more complex there are many many pass wait actually to even get
the same disease even hence is not one pathway that results in kent
costing actions of course people are different not everybody reacted the same
way on the inhalation of tobacco smoke or of air pollution
and actually you all know these famous examples of home video old
people have smoked a whole life yes people are different
so the hosting actions is more is orchestrated by multiple modify in fact
and therefore we have an orchestration of clean up all this is that the
two neat and it must be tailored to the local situations and source
so this is the simple policy framework and of course it's application is less than simple
recreation on the level of emissions is very crucial
second important part is to set very clear science based
air quality standards so the government should be fine
how air pollution air quality should be in the c. d.
and then of course you have to define and you have to implement the locally tailored
management plans at that is complex that is not
easy it involves many sectors many departments usually
a transport urban planners and others and implementation of course of those plans is even more
difficult than defining the planes but these are the steps and of course you
from the filter perspective you must be very interested in the very first one
to some extent in the second one if it's about money touring but uh of
course emissions emission control is very crucial and in our regions that costs
twenty years of course we must talk about traffic traffic is essential that they
really important source and it's not only important because of the mass
but also because of the proximity of traffic to people compared to industries which
tends to be ah class that i'm very often outside c. d.'s
traffic is among us it's in the middle where people if and state
so in missions must be controlled at the source and in fact
all particles i mean it shows should stop and not
even only part because most of the gases have to be put in question is very clear that play a role
and actually what's coming out he plays a role in the atmosphere in the
building of secondary pollutants which are again the source of health
so yes please regulate the emissions and yes
of course filters are one element
of that about it's not the only one and in fact on
uh highlighting here pay but that also just came out uh uh
this week i think there is a place also for filters
that's the mask and i have to say we from a rest in perspective for years we have totally new what's that
because we're actually fundamentally disagree to promote peace as a solution
and uh if you reach this uh there was an interview with me and others about a new
study that was done in china this new study has very beautifully shown that in fact
having such masks it's das have an impact the benefit
on some of the health effects so it is true that in the extreme
exposure situation of the terrible c. d.'s mega cities in the
south of this word yes with filters you can
re to use some of these health effects not all of them and not entirely and of
course our message has always been this is not this solution dissolution is at the source
we must take care of and in their part and that's what i'm saying indeed to view of course
i fully agree there must be a science to show if you wear a field but is it working how is it working
and which filters are working and of course if some feel does do work
people have the right to protect himself rather than to hope that the government's make a
change in the end in there that will happen maybe twenty years from now
so there is of course a very difficult discussion how to deal with individual and with this site
emission control must go beyond filters are is to maybe
you all know do regulation the euro six standards
very nice and moves to work cleaning clearing the cars but of course
and i heard yesterday you had that big talk here as well
yes zero emission mobility and i'm sorry to say that this doesn't
look like a business model for the filtering does three but
yes future some future cars uh will not be
pays them compassion anymore at all but it
mentioned also urban planning verbal plan is our key partners if it's about air pollution
and and other environmental effects fuel quality fair trade
are very important levels uh issues in
policy making and i want to really emphasise an example on this shoot quality
which is a very important current example on a global scale just to show you again
where we are in terms of iniquity and where there is still a lot to do
so what this map shows is the distribution of the national
standards of sulphur content that is permitted to be
in diesel so these are the governments who have set the standards and you see these shoots range
not only in colour spot in the p. p. and so in switzerland we are below ten it yeah
if you move up here there are some counties will officially allow
more than two thousand p. p. m. south or in diesel
that is a very very bad because of course diseases source a very nasty air pollution
cell where what's happening here is really another message to the industry
a very interesting study has figured out ways intensive research
over three years the importance of three straight years
uh in this business by taking in africa they're responsible for
thirty five percent of the worldwide oil and fuel traits
yeah they had a very strongly involved in africa this we straight
as a whole in fact the full chain from the crude
oil to very fine there is the production storage of diesel and to selling in the gas stations enough to sell
that sounds like fantastic that's suisse traders who have access to all
these beautiful technologies owned this whole chain that sounds like
a great business model for environmentally sustainable way of doing business
well guess what what they do is unfortunately very different
they buy this actually clean oil from africa one of the cleanest or else is coming
from africa they sell it to your because they don't have their own refineries
your three straight as and others what they do day makes a bland
the word wild or else they blend them and put them
at different levels of quality depending on the local regulation
and what they sell to what did industries calling the african
quality is to they're just be easily in the world
absolutely horrible what stable and here they sell it back this these who
has a more than three thousand p. p. m. actually eighty
percent of the of the gas station sell these little uh with more than one thousand p. p. m. in i think
suisse traders uh do that in africa of course they could never do that in switzerland
so you see here these are the results of samples taken in africa at the gas station
so this is not as to read this is the reality so in maui on one
station three two thousand seven hundred and eighty p. p. and sulphur in these these
well i hope you agree that something is very wrong here disposal mouthpieces a business model
and of course the consequences are very clear if you then go to air pollution
a mortal steve's estimates of air pollution in different cities
in africa here no wonder that does make
us it does have a huge problem in air pollution given these very very dirty arm
the usual that he sold their traffic as you do knowing the
seed disease anyway nightmare because urban planning is not ready for
for swallowing be huge amount of traffic they here they actually get our
old cars that are sold to africa because they are not
uh legally uh allowed anymore on our street so
there is a whole range of uh inequity
around to deal which causes the c. d. to be terribly polluted and
of course as you have heard before this is a direct
cost of mortality and morbidity in these cities
so do we um global uh the world bank as estimated actually what the costs
would be two souls these problematic stores and you see this is actually
they're interesting first of all the costs on the diesel would be very load additional costs on
selling clean diesel in the way we do in europe and actually they would say if
within ten years a huge amount of money in the sub
saharan african if this policy would have been done
and you see this is a very simple policy the government can seem pretty side by january
next year old these lead all gas station should be as clean as in switzerland
the technologies they i mean it's not the problem to do it
and in fact that that's the good news berlin began around that and then the out on that
two thousand fifteen they have taken this decision and actually that's the
other good thing this very interesting report of these n. g.
o. d. c.s n. g. o. has resulted in a few african
it's a government taking that decision very recently as well
so it has moved actually the agenda because you can imagine this report has
created a very very big fast in use african counties who are
of course a very very disappointed to see how these businesses organise
regulation of ending concentrations is to other make very
important element of doing the right policy
the w. h. o. is leading forty works uh the reckon they're reviewing of
the whole literature on health effects of air pollution and based on that
it provides guidelines to all counters in saying what's the
levels should be w. h. o. unfortunately cannot put
values as a regulation that's the government's right to do that but they can
right these guidelines and actually right now we are updating the guidelines
again for to publish them uh maybe in two three years to
new version but even the old ones have been very clear
how air pollution should be regulated if you take this science serious
and if you take it serious that people should be protected from adverse health effects okay
so i just show you the one example here um p. m. ten
w. h. o. safety and will mean should not be higher than twenty micrograms per cubic meter
and you see here to very few counter is it's about nine not even ten pound choose who
have this value in their local regulation or a very similar ready
and the rest of the words in you'll be science uh take a sad of course euro as i have
shown you before europe has invested a lot in science in showing the evidence of peace out effect
but on the government side terrible yeah so they have all these counter is uh
who block the right policies very active against the right policies has in germany
and the netherlands and uh of course eastern europeans are very happy to not see more stringent
um uh regulations as well this is simply wrong this is against a protection of peoples well
and you see actually hid the sad situation on the global scale we have just published a
paper i'm ready recently looking into the worldwide situation
of regulation that this is a sobering
you see here for example in africa all only if third of the counties have even
at least one the regulation for one pollutant at the
whole majority of counties have absolutely zero regulation
so there is a lot to do
ah well if you go online or into the paper you would see
the distribution of these regulations how they comply with the proposed values
um i'll show u. p. n. ten and p. m. two point five because some counties regulate either one uh which is uh
also an option which is not too bad so you see here there are some counties green
or yellow but the vast majority have a real serious problem that a good age
and why do i emphasise that i mean i would not sell you regulation if he's would not work
but there is there is strong evidence on a global scale that it
doesn't work it works very well this is los angeles famous
smoke c. d. of the last century today is clean that in many european cities
today people know that belief surrounded by beautiful mountains i've seen
them almost every day when i was driving to my
a workplace in l. a. forty years ago people would not even know that there are mount
the same is true for switzerland you see this development in switzerland some belief
that the air pollution is the price to pay for economic development
it's total nonsense uh just as a reminder the g. d.
p. gross domestic product in switzerland has developed a very
well over the past twenty five years i don't think we can talk about having an economic disaster in crises
basically kilometres have grown up has one indicator of
people getting better at wealthier and wealthier
but told me this connection from emissions yeah i know x. one example
has gone down drastically i could show you the levels of particles of other pollute
drastic decline air pollution is getting lower and lower air quality is getting
better and better actually in all waste encounters not only in switzerland
so it's just proof of what and emphasising eek works
and it's worth doing because doing that is much cheaper than not doing it economically
well i could say well it's great that switzerland but i have shown you
before the big problem actually is that even the western in this three
acts and we have societies actually we are part of the problem
so this is shows just one side of the story but
what has happened a disease also he didn't hear switzerland and
all the western counties have outsourced pollution to other places
and and they have a nice paper just came out this week in nature i wanna emphasise it here they have
evaluated the burden of mortality of disease
duo to consumption and production in your count three and
all over the glow about just wanna emphasise too critical statements western europe and the us
in all those regions directive look that they are the only regions who cost substantially
higher air pollution in other counters to accommodate their own consumption in there from
and on the other side china india and asia they take the highest share of
air pollution for the production of the quotes that are consumed in other counties
so i would hope you understand um and that there is a neat
for change because what actually happened that's a consequence of that over the last
twenty five years to clean places get clean air and clean or
and polluted places get more and more clued so in some i want to emphasise and summarise
there has been enormous progress we do understand very well the
problem we know it's effects on but the research
policy making measurements monitoring are very an equally distributed over the world
and um it's a very clear duty for the citizens and the policymakers and for the industry
support more equitable way of approaching the problem and the solutions because the solutions are the
and they should belong to all countries all over the world thank you very much for a change
