Republican John McCain pledged to take the lead in combating global climate change if elected president in a speech that set him apart from the policies of U.S. President George W. Bush.

In remarks he prepared to give at a wind technology firm in Portland, Oregon, on Monday, the Arizona senator said he would seek international accords to reduce greenhouse gas emissions, and would 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 said in remarks he planned to give at the Vestas Wind Technology plant.

“Good stewardship, prudence, and simple common sense demand that we act to meet the challenge, and act quickly,” he added.

McCain is visiting Oregon where Democratic rival Sen. Barack Obama is favored to beat Sen. Hillary Clinton in the Democratic primary on May 20.

The speech set McCain apart from fellow Republican Bush, who has been skeptical about global warming throughout his eight-year term, and was calibrated to win support from independents and centrist Democrats he will need to convince to win office in the November election.

“I will not shirk the mantle of leadership that the United States bears. I will not permit eight long years to pass without serious action on serious challenges,” he added.
