"PORTLAND, Oregon (Reuters) - Republican John McCain, differing sharply with President George W. Bush, said on Monday he would pursue mandatory U.S. curbs on greenhouse gas emissions if he wins the White House in November.
The Arizona senator vowed to take the lead in combating global climate change, seek international accords to reduce greenhouse gas emissions and offer an incentive system to make businesses in the United States cleaner.
"The facts of global warming demand our urgent attention, especially in Washington," McCain told an audience at the Vestas Wind Technology plant in Portland, where he signed the blade of a giant wind turbine and chatted with service technicians."
