The
...
U.S.
...
GHG
...
Inventory
...
is
...
EPA's
...
official
...
source
...
of
...
total
...
U.S.
...
emissions.
...
The
...
Inventory
...
is
...
developed
...
using
...
(primarily)
...
top-down
...
methods
...
and
...
covers
...
all
...
sectors
...
of
...
the
...
economy.
...
Based
...
on
...
the
...
Inventory:
...
electricity
...
generation
...
accounts
...
for
...
approximately
...
35%
...
of
...
U.S.
...
emissions,
...
transportation
...
accounts
...
for
...
approximately
...
25%,
...
industry
...
accounts
...
for
...
approximately
...
20%,
...
commercial
...
and
...
residential
...
sources
...
account
...
for
...
approximately
...
10%,
...
and
...
agriculture
...
accounts
...
for
...
less

than

10%.

The
...
GHG
...
reporting
...
program
...
(GHGRP)
...
is
...
developed
...
using
...
bottom-up
...
methods
...
and
...
covers
...
roughly
...
85
...
to
...
90
...
percent
...
of
...
total
...
U.S.
...
GHG
...
emissions.
...
This
...
includes
...
direct
...
emissions
...
data
...
reported
...
by
...
stationary
...
sources
...
-
...
including
...
nearly
...
all
...
emissions
...
from
...
electricity
...
generation
...
and
...
most
...
emissions
...
from
...
industry
...
which
...
account
...
for
...
roughly
...
50%
...
of
...
total
...
U.S.
...
emissions.
...
This
...
also
...
includes
...
GHG
...
data
...
reported
...
by
...
suppliers
...
of
...
fossil
...
fuels
...
and
...
industrial
...
gases
...
-
...
which
...
accounts
...
for
...
the
...
vast
...
majority
...
of
...
emissions
...
from
...
transportation,
...
commercial
...
and
...
residential
...
sources,
...
roughly
...
35-40%
...
of
...
total
...
U.S.
...
emissions.
...
The
...
GHGRP
...
does
...
not
...
include

emissions

from

the

agriculture
...
and
...
land
...
use
...
sectors,
...
or
...
other
...
small
...
sources
...
of
...
emissions.

that

the

data

for
