Arnold Schwarzenegger, the Republican governor of California, is scheduled to address this year's conference of Britain's Conservative Party.

Party officials said Sunday in London that Schwarzenegger would speak about climate change at the party's annual meeting.

British conservative leader David Cameron said Schwarzenegger had shown tremendous leadership in pioneering measures to protect the environment.

Schwarzenegger signed into law last year a measure that imposed emissions limits on utilities, refineries and manufacturing plants. The goal is to cut greenhouse gas emissions 25 percent by the year 2020.

He said California could set the standard for the United States and the rest of the world.
