U.S. to complete key step for regulating aircraft emissions -sources
By Valerie Volcovici
WASHINGTON, July 22 (Reuters) - The Environmental Protection Agency will as soon as Monday finalize a scientific finding that greenhouse gases from aviation endanger human health, obligating the United States to regulate emissions from commercial aircraft, sources told Reuters.
The EPA's "endangerment finding" requires the agency to implement greenhouse gas emission standards for U.S. aircraft, which accounts for 11 percent of U.S. transportation greenhouse gas emissions and is one of the largest sources of emissions not yet regulated.
EPA Administrator Gina McCarthy is expected to sign the endangerment finding as soon as Monday, two sources familiar with the process told Reuters.
The EPA did not immediately respond on Friday to confirm the timing.
The United States has said it wants to align its aircraft standard with one being developed by the United Nations' International Civil Aviation Organization (ICAO).
McCarthy told Reuters on Tuesday that the agency would finalize the finding "shortly" and that it would "send a signal that the U.S. can integrate (the ICAO standard) in our regulatory structure."
In February, after six years of talks, the ICAO agreed on a global standard aimed at makers of small and large planes, including Boeing Co, Airbus Group SE and Embraer SA that will apply to all new aircraft models launched after 2020.
The standard must still be approved by ICAO's governing council in Montreal in September-October. Continuación...
