The Trump Environmental
Protection Agency (EPA)
proposed the first
ever greenhouse gas
emission standards
for large passenger jets.
The proposed standards,
would phase in during 2023-2028.
They would match
international airplane
CO2 standards
adopted in 2017
by the International
Civil Aviation
Organization
(ICAO).
The proposed rule is needed
by U.S. aircraft manufacturers
so they are not shut out
of foreign markets
by the other 192 ICAO
member governments.
The US is the
world's leading
aircraft manufacturer,
exporting three of
every four planes
built here.
U.S. civilian airplane
manufacturers
will be forced to get
CO2 emissions
certification
from an aviation
certification authority
of another country,
so their new planes
can operate
internationally.
Aircraft
CO2 emissions
are proportional to
to fuel consumption,
so ICAO standards
are fuel-efficiency
standards.
Current,
aircraft models
that would not meet
the new standard
must be out
of production
when the
new standards
take effect.
To avoid
the new standards,
the Trump EPA
would have to
overturn the
December 2009
greenhouse gas
endangerment finding
of the Obama EPA.
The Trump administration
has not tried to do that.
The global aviation industry
accounts for about 2.5 percent
of all man made CO2 emissions,
with U.S. aviation accounting for
about 0.6 percent of total
global CO2 emissions.
If every US
airplane passenger
decided to STOP flying
until the year 2100,
the climate models,
which grossly
over estimate
global warming,
predict the global average
temperature would decline
by less than 0.1°F. in 2100 !
