The House approved legislation (H.R. 2594) October 24 that would prohibit U.S. airlines from participating in the European Union emissions trading scheme, which is scheduled to take effect for airlines this January. The European Union Emissions Trading Scheme Prohibition Act would direct the Transportation secretary to prohibit domestic aircraft operators from participating in the trading scheme and instruct the Federal Aviation Administration to negotiate or take action to ensure U.S. aviation operators are held harmless from not participating in the scheme.
