"Diplomatic talks on a deal to curb greenhouse gas emissions from the global aviation industry have intensified recently as EU and U.S. officials try to stave off the threat of a trade war, lawmakers and observers said."

"Peter Liese, a member of the European Parliament from the conservative German Christian-Democratic Union, led a delegation to meet with Obama administration officials in Washington last week to discuss the issue.

The International Civil Aviation Organization (ICAO), the United Nations' civil aviation body, has until September to complete a resolution on a market-based plan that would curb rising greenhouse gas emissions from global airlines."
