the
European
context
actual
and
updated
environmental
data
is
brought
out
through
environmental
product
declaration
(EPD)
programmes.
There
are
several
national
or
field
related
programmes,
as
EPD-‐Norway
in
Norway,
IBU
EPDs
in
Germany,
and
Wood
for
Good
in
UK.
EPDs
are
completed
according
to
normative
standards;
general
standard
ISO
12025
and
construction
products
related
EN
15804
and
ISO
91930.
A
short

valid
EPDs

Based
on
these
EPDs,
a
comparison
between
different
products
is
difficult.
Regarding
energy
consumption,
primary
energy
increases
by
approximately
15%
in
heat
treated
timber
compared
to
kiln
dried
sawn
timber
(EPD-‐Norway).
The
ThermoWood
Handbook
(2003)
also
reports
a
25%
increase
in
energy
demand
during
the
drying
phase.
Therefore
wood
modification
should
prolong
the
service
life
of
the
product
to
correspond
(in
minimum)
to
the
increase
in
environmental
impacts
during
production
in
order
to
make
the
modification
environmentally
meaningful.
Emissions
are
always
energy
production
related
and
cannot
be
compared
directly.
A
more
detailed
comparison
for
whole
life
cycles
of
products
would
be
needed
more
specific
data
and
assumptions
for
the
use
stage.
