Environmental
product
declarations
(EPD)
for
wood
products
have
been
around
in
Norway
for
about
20
years,
but
there
has
been
a
large
increase
in
use
and
availability
in
recent
years.
The
use
of
EPDs
are
for
whole-‐building
life
cycle
assessments
(LCA)
and,
especially,
accounting
for
the
carbon
footprint.
These
uses
have
been
pushed
forward
by
the
Norwegian
Government
Building
Company
(Statsbygg)
and
the
environmental
classification
system
of
buildings
BREEAM-‐NOR.
The
Norwegian
version
of
BREEAM
gives
credits
for
having
EPDs
for
the
major
materials
used
in
a
project
and
this
has
been
a
game
changer
for
the
demand
for
EPDs
in
Norway.
The
supply
and
availability
was
driven
at
the
start
by
a
few
companies
being
proactive,
but
are
now
more
and
more
made
by
companies
to
satisfy
their
customer’s
requirements.
The
third
party
verified
EPDs
for
wood
products
was
at
the
start
mostly
made
for
large
product
groups
and
representative
for
all
members
of
the
Norwegian
Wood
Industry
Federation.
The
trend
now
is
towards
more
specific
EPDs
and
other
industries
have
starting
making
EPDs
specific
for
single
construction
projects.
The
introduction
of
EN
15804
made
it
necessary
to
change
several
key
methodological
practices
for
wood
EPDs
in
Norway
on
issues
such
as
co-‐product
allocation,
modularity,
biogenic
carbon,
end-‐of-‐waste
and
possibilities
to
include
benefits
beyond
the
lifecycle.
In
Norway,
instantaneous
oxidation
of
biogenic
carbon
had
always
been
the
common
practice
and
studies
did
often
not
include
end-‐of-‐life
scenarios.
The
change
of
approach
to
include
uptake
and
emissions
of
biogenic
carbon
in
the
modules
where
they
appear
was
therefore
controversial
at
the
start.
One
key
way
to
deal
with
this
controversy
was
to
have
high
transparency
of
biogenic
carbon
flows
in
Norwegian
EPDs.
The
use
of
foreign
EPDs
for
wood
products
are
however
often
frustrating
for
LCA-‐practitioners
as
they
seldom
report
the
amounts
of
biogenic
carbon.
Several
EPDs
have
been
developed
for
modified
wood
through
the
Norwegian
EPD-‐foundation
in
accordance
with
EN
15804.
These
are
presented
in
Table

along
with
the
carbon
footprint
for
1
m3
declared
unit
with
optional
modules
of
maintenance,
repair
and
waste
processing.
