{longname} Q414. How can I determine what percentage of total GHGs come from a particular sector since the GHG Reporting Program (GHGRP) does not cover 100% of U.S. emissions? {longname} |
A414.
...
To
...
calculate
...
a
...
rough
...
percentage
...
of
...
U.S.
...
emissions
...
from
...
a
...
particular
...
sector
...
in
...
the
...
GHG
...
Reporting
...
Program
...
database,
...
take
...
the
...
total
...
emissions
...
from
...
the
...
sector
...
of
...
interest
...
and
...
divide
...
it
...
by
...
the
...
total
...
U.S.
...
emissions
...
reported
...
in
...
the
...
...
...
...
...
...
...
...
...
...
(6,702.3
...
million
...
metric
...
tons
...
of
...
carbon
...
dioxide
...
equivalent
...
in
...
2011).
...
It
...
is
...
important
...
to
...
note
...
that
...
for
...
some
...
sectors,
...
...
...
are
...
required
...
to
...
report
...
their
...
emissions
...
to
...
the
...
GHGRP.
...
For
...
others
...
however,
...
...
...
...
...
...
...
...
...
...
...
...
are
...
required
...
to
...
report
...
and
...
the
...
total
...
emissions
...
reported
...
to
...
the
...
GHGRP
...
is
...
less
...
than
...
total
...
U.S.
...
emissions
...
from
...
that
...
source.
