EPA moves to regulate

A second look at this issue.  We believe the burden will force change, maybe some short-term bumps in cost of airline tickets, but will end with incredible efficiency, use of new tech and will bring better flights and earnings to the airline industry.

EPA moves to regulate climate-warming airliner pollution

WASHINGTON (AP) -- Jet engine exhaust from airliners endangers human health and adds to climate change, the government found Monday in taking the first step toward regulating those emissions.

The Environmental Protection Agency said it will use its authority under the Clean Air Act to impose limits on aircraft emissions.

Jet engines spew significant amounts of greenhouse gases, including carbon dioxide and methane, into the upper atmosphere, where they trap heat from the sun. But proposed rules such as imposing fuel-efficiency standards have faced stiff opposition from aircraft makers and commercial airlines.
Aircraft emissions were not addressed as part of the landmark global climate agreement agreed to in Paris in December.

"Addressing pollution from aircraft is an important element of U.S. efforts to address climate change," said Janet McCabe, EPA's acting assistant administrator for air and radiation.
McCabe said aircraft are the third largest contributor to greenhouse gas emissions in the U.S. transportation sector, and that is expected to increase. Cars and trucks already are regulated.
The EPA's findings do not apply to small piston-engine planes or to military aircraft.

A U.N. panel in February recommended new emissions standards for international flights that require an average 4 percent reduction in fuel consumption during the cruising phase of flight. The new regulations from the International Civil Aviation Organization require that new aircraft designs meet the standards beginning in 2020, and that designs already in production comply by 2023.

Environmental groups have criticized those new international standards as too weak to actually slow global warming. Planes burn the most fuel during takeoffs and landings. Cruising at high altitudes is the most fuel-efficient period.

Environmentalists say aviation accounts for about 5 percent of global greenhouse emissions, though the U.N. and EPA cite studies concluding it's actually less than 2 percent.

The EPA finding announced Monday is expected to result in fuel-efficiency standards for domestic carriers, which critics call long overdue. The EPA acted after a coalition of environmental organizations filed notice of their intent to sue the agency over its inaction.

"People should not have to choose between mobility and a healthy climate," said Marcie Keever, legal director for the environmental group Friends of the Earth. "Now it's time for the Obama administration to issue a strong rule, to hold the aviation industry accountable."

Though environmental groups are pushing EPA to adopt stricter standards, the airlines and aircraft manufactures want to U.S. to adopt the more modest reductions proposed for international routes.
U.S.-owned airliners account for nearly one-third of all aircraft pollution worldwide. While carbon emissions from land-based sources are largely in decline, pollution from airplanes is projected to triple by 2050 without stricter limits.

A spokeswoman for the aviation industry said U.S. air carriers have already been making strides to burn less fuel and generate less harmful exhaust.

"As aviation is a global industry, with airlines operating internationally and aircraft manufacturers selling their aircraft in international markets, it is critical that aircraft emissions standards be set at the international level and not imposed unilaterally by one country or set of countries," said Jean Medina, of the group Airlines for America.
