“I
profoundly
believe
that
a
cap-and-trade
mechanism
is
the
only
way
we
will
solve
the
emissions
issue,”
Hayward
said
today
in
a
speech
at
the
Peterson
Institute
for
International
Economics
in
Washington.
The
US
House
of
Representatives
narrowly
passed
cap-and-
trade
legislation
last
year
that
would
regulate
companies
responsible
for
85%
of
US
greenhouse-gas
emissions
through
a
system
where
pollution
rights
could
be
bought
and
sold.
The
legislation,
which
later
stalled
in
the
Senate,
favored
the
electricity
industry
over
the
oil
companies
that
produce
transportation
fuels
like
gasoline,
Hayward
said.
