BRUSSELS/STRASBOURG, Dec 17 (Reuters) - The European Union finalised plans for its battle against global warming on Wednesday, seeking to lead the way towards a broad alliance including other big polluters like China and the United States.

The European Parliament approved a cut in carbon dioxide emissions to 20 percent below 1990 levels by 2020, heeding warnings of severe weather, famine and drought as the atmosphere heats up.

The deal takes on a greater importance coming just before Barack Obama assumes the U.S. presidency, amid hopes in Europe he will cooperate more on tackling climate change than incumbent George W. Bush.

"Happily Bush is going," said European Environment Commissioner Stavros Dimas. "Everybody knows what Mr Obama has set as priorities -- energy security and climate change."

World leaders will meet in Copenhagen next December to try to agree a global deal, but preparatory talks in Poland ended last week with deep divisions between rich and poor nations.

The advancing economic crisis had at times threatened to derail the EU's climate negotiations.

A myriad of concessions to water down the costs for industry helped pin down a deal, although this fuelled criticism from environmental groups.
