I.        Introduction

In the grand scheme of things, aviation may not represent a huge source of concern with respect to climate change. But neither should the aviation industry (airports included) ignore the fact that aviation does contribute to climate change not only through the emission of carbon dioxide (CO2) but also through the emission of nitrogen oxides (NOx), aerosols and their precursors (soot and sulfate), and increased cloudiness in the form of persistent linear contrails and induced-cirrus cloudiness. The intent of this series of articles is to examine the effect aviation has on climate change, outline the regulatory and legal framework that is developing, and to suggest avenues for the aviation industry to pursue in the future.  The first challenge is to clear up some misconceptions about aviation and climate change so that we can move forward with accurate and up-to-date information.

II.      Some Facts About Aviation and Climate Change

In Aviation and Climate Change: the Views of Aviation Industry Stakeholders, the aviation industry makes several claims regarding the impact aviation has on climate change. First, the industry claims that “over the past four decades, we have improved aircraft fuel efficiency by over 70 percent, resulting in tremendous savings.” As a result, the industry continues, “given the significance of fuel costs to the economic viability of our industry, our economic and environmental goals converge.” Second, the industry claims that “because of our aggressive pursuit of greater fuel efficiency, greenhouse gas (GHG) emissions from aviation constitute only a very small part of total U.S. GHGs, less than 3 percent.” However, in order to assist the industry in its obligation “to further limit aviation’s greenhouse gas footprint even as aviation grows to meet rising demand for transportation around the world,” those claims of progress need to come under a microscope.

        A.            Contribution of Aviation to Climate Change Remains Subject to Debate

First, how much aviation contributes to climate change is still up to debate. Several governmental and aviation industry organizations have been reporting a “less than 3%” number for quite some time while environmental groups, particularly in Europe, claim that the percentage is anywhere from 5 to 9%. In examining the claims and counterclaims concerning emissions of GHG, one has to be very careful about the language and the metrics used in determining the “impact” any given industry will have on “climate change.” Many reports and studies focus only on CO2, since the amount of CO2 produced both naturally and by humans is overwhelming. However, as just about everyone knows by now, there are other gases and anthropogenic actions that exacerbate climate change. For example, the U.S. EPA recently proposed regulations that would require major emitters of six “greenhouse gases” to report their emissions to the EPA on an annual basis. Those six greenhouse gases are: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), sulfur hexafluoride (SF6), hydrofluorocarbons (HFCs), perfluorochemicals (PFCs), and other fluorinated 20 gases (e.g., nitrogen trifluoride and hydrofluorinated ethers (HFEs)). It also should be kept in mind when discussing climate change, especially with respect to aviation, that water vapor is estimate contribute anywhere from 36% to 72% of the greenhouse effect. This is important because the radiative forcing effect of cirrus cloud formation from the aircraft is a significant contributor to the greenhouse effect. As pointed out above, it is generally accepted that for aviation the GHGs of concern are CO2, nitrogen oxides (NOx), aerosols and their precursors (soot and sulfate), and increased cloudiness in the form of persistent linear contrails and induced-cirrus cloudiness.

  • FAA Administrator Babbitt’s Pilot Fatigue Advisory Committee delivers its recommendationsAn advisory committee on pilot fatigue,convened by Administrator Babbitt, delivered its recommendations to the Federal Aviation Administration late Tuesday, September 1, 2009.  Committee members

Writing in the Wall Street Journal, Senior Special Writer Andy Pasztor states:

Federal Aviation Administration chief Randy Babbitt, in his most detailed comments yet about combating pilot fatigue, vowed to tailor future regulations to better reflect the safety challenges facing commuter pilots.  In a speech to the country’s largest commercial-pilot union, the agency’s administrator said the current "one size fits all" regulations don’t adequately take into account fatigue typically experienced by commuter pilots, some of whom fly five or more segments per day.

This speech by Administrator Babbitt underscores the growing concern about Pilot fatigue and safety of the aircraft that are flown.  Ever since it came to light that the co-pilot of the Continental Flight 3407, which crashed in Buffalo, New York, had commuted from Seattle to Newark to be on the flight, and that the pilot was not familiar with the de-icing procedures for the type of aircraft he was flying, pilot training, fatigue and maintenance have been hot topics.

Administrator Babbitt vowed in his speech to the Air Line Pilots Air Safety Forum not to wait until the Congress gets its act together and passes legislation.  He said that he has set up a rulemaking committee studying fatigue:  "I want to make sure that we get the answers we need as working men and women aviators.  In rulemaking not only does one size not fit all, but it’s unsafe to think that it can."

Although not part of his rulemaking committee, Administrator Babbitt also mentioned that the FAA is holding a series of 12 nationwide airline safety forums aimed at "stimulat[ing] a safer, more professional enviroment at regional airlines. . . the discussions are focusing on air carrier management responsibilities for crew education and support, professional standards, flight discipline, training standards and performeance."

This is not to say that Congress is standing still waiting to see the outcome of these rules and meetings.  The Senate Subcommittee on Aviation has a held a series of three hearings on Aviation Safety, the most recent being August  6, 2009, which focused on "the relationship between the major, or network, airlines and their regional airline partners." (Witness lists for the three hearings appear after the jump).  The goal, as expressed by Subcommittee Chairman Jay Rockefeller (D-W.Va.) is to "to determine if there are further steps we can or must take to ensure there is one level of safety throughout the commercial air transportation system."

Maybe Administrator Babbitt got it right when he concluded his remarks by stating that "if you think the safety bar is set too high, your sights are set way too low."Continue Reading Pilot Safety Rule Focus of New FAA Administrator Babbitt

On Wednesday, July 29, 2009, the bipartisan leadership of both the Committee on Transportation & Infrastructure and the Subcommittee on Aviation introduced H.R. 3371, the "Aviation Safety Bill" designed to "enhance airline safety by setting new training and service standards for commercial pilots."  This bill came primarily as a response to the Senate Commerce Committee’s passage

In a per curiam Abbreviated Disposition that will not be published, the U.S. Court of Appeals for the District of Columbia Circuit summarily denied 12 separately-filed petitions for review that questioned the legality of the Federal Aviation Administration’s Environmental Impact Statement for its East Coast Airspace Redesign. The matter, Rockland County v. Federal Aviation Administration

FAA Administrator Randy Babbitt told the Senate Subcommittee on Aviation Wednesday, June 10, 2009, that small regional airlines are held to the same safety standards as the major carriers. Babbitt says he and Secretary of Transportation Ray LaHood are ensuring that the FAA is taking steps to ensure that that is the practice as well as the law. However, FAA Inspector General Calvin Scovell  says that is not currently the case.

Subcommittee Chair Byron L. Dorgan (D-N.D.) opened the hearing with the statement that he was concerned that there is a double standard in aviation instead of  "one level of safety for both regional and major carriers."  This issue has come to the forefront since the crash of Colgan Air flight in Buffalo, raising issues of pilot training, proficiency and pay at regional airlines.  The investigation into that crash has revealed that the pilot flew cross country as a passenger on a flight the night before and lacked experience in the deicing procedures for the type of aircraft that crashed.

FAA Administrator Babbitt said that the same safety laws and regulations apply across the board to all airlines, regardless of whether they are regional or national in scope.  That being said, Administrator Babbitt stated that there is much to be done to improve safety and that he and Secretary of Transportation Ray LaHood are committed to focusing on inspection of aircraft and safety.

FAA Inspector General Calvin Scovell, however, stated that although the laws and regulations may be the same, in practice there are two standards.  He stated that he was particularly concerned about the difference between pilots’ training and level of flight experience in the two types of airlines.  The major airlines did not escape the hearing unscathed.  Scovell also testified that  there have been many lapses in oversight of the major airlines’ technical programs, similar to the problems that came to light last summer concerning Southwest Airlines. In particular, he was concerned that 7 major airlines missed "Air Transportation Oversight Systems" inspections, some had been allowed to lapse  "well beyond the 5-year inspection cycle."

NTSB Chairman Mark Rosenker also had some choices remarks for the FAA.  He informed the panel that the FAA has failed to heed recommendations suggested by the NTSB that would produce greater safety.  When asked how many recommended changes were outstanding, Chairman Rosenker stated that there about 450 recommendations still outstanding with some 10 – 15 years old.  Sen. Barbara Boxer (D-Cal.) called this an "outrage" and an indictment of the FAA, "it is not about anyone personally, it is the institution, it is the way they think, and it is very disturbing to me."

In the end, Administrator Babbitt promised to consider the NTSB recommendations, and although the FAA will not adopt them all, he would make the FAA "more transparent" about the process.
