Washington: Environmental groups have urged the United States to back a global deal to curb carbon emissions produced by planes, noting that global aviation emits more of the greenhouse gas than all but six of the world's nations.
The groups, alarmed at scant progress toward an agreement within a United Nations aviation body, presented a petition with more than 60,000 signatures on Monday to a representative of the US State Department.
The petition asked US Secretary of State John Kerry to secure agreement under the International Civil Aviation Organization (ICAO) for a market-based approach to curb heat-trapping emissions produced by planes.
