March 29, 2012 - ALPA first vice president Capt. Sean Cassidy yesterday participated in a congressional roundtable discussion, urging the administration and Congress to block U.S. participation in the EU’s emissions trading scheme. The timing of the congressional roundtable coincided with an opinion piece in Tuesday’s USA Today by ALPA president Capt. Lee Moak with A4A President Nick Calio, opposing the EU-ETS.
