Prague - European Union environment officials Wednesday urged the world's major economies to join the 27-member bloc in its ambitious plans to curb global warming.
"We want to offer co-leadership to the United States and other important countries," said outgoing Czech Environment Minister Martin Bursik, whose country currently chairs the EU.
The call came some eight months before a United Nations conference in Copenhagen, which aims to set new targets for reducing emissions of gases heating up the planet.
