His latest foray - regulating commercial aviation - had the
opposite effect.
On Wednesday, the administration took a first step toward cutting
greenhouse gas emissions from the nation's fleet of aircraft,
releasing a scientific finding that said emissions from plane
engines pose a risk to human health because they contribute to
climate change.
But the Environmental Protection Agency (EPA) did not immediately
propose new regulations. Instead, it signaled it would implement a
global emissions standard being developed by the United Nations'
International Civil Aviation Organization (ICAO) that is due to be
released next year.
Those rules are expected to apply only to new aircraft designs
beginning in 2020, leaving most of the world's existing fleets
unaffected for years to come.
That decision was greeted with cautious optimism from the aviation
industry, which says it is making strides on energy efficiency and
wants the United States to coordinate any new regulations with the
rest of the world.
That was precisely what worried environmentalists, who warned that
relying on a global agreement forged under UN auspices seeking
consensus would be doomed to produce weak rules.
"The EPA is declaring aircraft greenhouse gases to be dangerous to
all of us, but is passing the buck on doing anything about it," said
Vera Pardee, an attorney for the Center for Biological Diversity
that was among several green groups pushing the administration for
years to adopt new regulations.
Indeed, the EPA was prodded to act on aviation only after a long
legal fight. A collection of environmental groups petitioned the
agency to bring in new aviation regulations in 2007 and sued it to
do so in 2010, winning a federal court ruling two years later that
ordered the U.S. government to regulate aircraft emissions under the
Clean Air Act.
On Wednesday, the EPA acknowledged "certain classes of airplane
engines contribute to air pollution that causes climate change
endangering public health and welfare," and promised to follow
ICAO's lead on new rules.
Airline companies were broadly supportive of the administration's
approach. The industry favors a global standard over national
standards because carriers operate all over the world and want to
avoid a patchwork of rules and measures, from taxes to emissions
trading programs.
"We feel this is the right thing for the EPA to be doing, as a
precursor to be able to adopt what comes out of ICAO," said Paul
Steele, senior vice president at the International Air Transport
Association.
"If you're a big airline and you're flying to 100 countries a day,
then complying with all those different regimes is an administrative
nightmare."

IMPORTANT SECTOR
Controlling aviation emissions is seen by climate scientists as a
vital cog in the wider attempt to curb global warming. Commercial
aviation accounted for three per cent of overall U.S. emissions and
11 percent from the U.S. transportation sector in 2013, the EPA
said. The U.S. industry was responsible for nearly 30 percent of
global aircraft emissions in 2010, the latest year with complete
global emissions data.
Environmental groups cite studies indicating unregulated aviation
emissions could triple by 2050, and they have been critical of the
ICAO negotiations, saying the organization's targets are not
ambitious.
Sarah Burt, an attorney with Earthjustice, another organization that
sued the EPA, said ICAO is poised to set a "business-as-usual"
standard that will lock in emissions increases for decades to come.
"The ICAO standard won't deliver substantial reductions because they
are setting a standard that 90–95 percent of aircraft already meet,"
she said, adding that planes tend to stay in service for 20 to 30
years.
The burden for meeting those lower emissions standards will fall to
aircraft and engine manufacturers such as Boeing Co, Airbus Group
SE, Pratt & Whitney and Rolls Royce [RROYC.UL]
But some experts want the new standards to apply to any plane
delivered to carriers after 2020, rather than simply for newly
designed aircraft.
"Applying the standard to all new aircraft delivered after 2020 is
key," said Dan Rutherford, director of the International Council on
Clean Transportation Program. "If ICAO grandfathers in existing
designs, the standard would cover only about 5 percent of the global
fleet by 2030."
An EPA spokesman defended the decision to work through ICAO, arguing
that an international standard would cover more planes than a simple
domestic one.
But some critics want the White House to seek more aggressive
targets than what is achievable under the consensus-driven
international organization.
“If the Obama administration wants this to stand up next to its much
more ambitious cars and power plants rule, it will need to do much
more than follow the weak lead of ICAO,” said Burt of Earthjustice.
