Thematic Assessment Report on Ammonia
Rob Maas @ TFMM – 2 May 2018
Request
Executive Body of
the
UN Air
Convention
,
Dec 2017
to
TFIAM/TFMM
Slide2Request
Prepare
a
concise
(
low/no budget
) report
that
shows
the
benefits of
further
action on ammonia
E.g.:
What
is
the
current
status of
(a) policy
and
(b)
science
?
What
will
be
the
damage
to
health
and
ecosystems
in
the
coming
decades
with
policy
inaction
?
Which
policy actions
will
be
most
effective
?
How
could
climate
and
food policy
influence
ammonia
emissions
?
Slide3Integrated
approach Everything has been
said
,
so
how do we make a difference?
Slide4Current
status (1)Large
differences
in
ammonia
emission densities
Slide5Current
status (2)strong correlation
with
differences in biodiversity loss
Slide6Current
status (3)
Game changer: ammonia plays important role in SIA formation and PM2.5 exposure in many cities
Slide7Current policy (1)
so far,
only
modest
reductions
in ammonia emissions

is (in different
parts of Europe) more effective: ammonia or NOx-reduction? Uncertainties in abatement potential, including ‘applicability’Uncertainties in relative toxicity of PM-species

Slide13Policy issues
What will
be
the costs and benefits of
additional
ammonia
reduction
?
Will
m
ethane
and
N2O policies contribute to NH3-reduction? Could food policy contribute to ammonia reduction –> healthy and sustainable dietsWill food prices remain affordable?How to win political support?
Slide14Towards
a
circular
agricultural
economy
?
Waste
less
nutrients
,
use less feed and chemical fertilizer
Slide15To conclude
How can we make a difference?
What should get more attention in the report?
What can TFMM-experts contribute?
