1.Motivation of the study
3-‐reason
to
start
discussion
about
E-‐book
1.
To
find
real
environmental
impact
•Review
suspicious
look
at
commonly-‐accepted
idea
that

E-‐book
has
less
load
compared
to
P-‐book
2.To
defend
ourselves
from
one-‐sided
claim

•E-‐organization
prepares
E-‐book
quantification
method

which
might
have
negative
influence
on
our
industry
3.To
show
presence
of
printing
industry
•Many
LCA
experts
in
E-‐industry
are
skilled
at
calculating

environmental
impact,
so
we
should
counteract

6. Conclusions and Discussions
Conclusions
1.E-‐book
is
not
superior
compared
to
P-‐book
all
the

time
by
the
scale
of
CO2e
2.Key
element
is
the
calculation
of
the
load
from

E-‐book
device

Discussions
1.How
to
average
usage
hours
of
E-‐book
device?
2.How
to
average
reading
speed
of
E-‐book?

7. Expected role for ISO130 WG11
What
we
have
to
think
and
do
1. We
should
try
to
collect
information
periodically
from
IEC

(TA13?
is
tasked
to
set
E-‐book
related
standard)
and
ﬁnd
a

way
to
work
together
if
possible;
it
will
be
Nakamura’s
task

since
TA13
is
controlled
by
Japanese
manufacturers.
2.We
might
propose
calculation
scheme
for
E-‐book;
it
means

that
we
suggest
calculation
framework,
such
as
scenario

setting
about
“How
to
compare
two
of
those?”,
not

detailed
assessment
methods
for
electronic
devices.
3.We
can
work
on
case-‐study
for
diﬀerent
printed
products
in

the
near
future
to
compare
Paper-‐products
to
E-‐products

and
publicize
in
appendix
of
16759
or
special
edition
of
the

report
at
the
very
least.
