British Prime Minister Tony Blair and California Governor Arnold Schwarzenegger met on Tuesday to discuss the trans-Atlantic battle against global warming.
Schwarzenegger, a conservative who has put major emphasis on the fight against climate change, praised Blair's "great leadership" on the environment.
He said that during a decade in power, the British leader has "proven to the world that you can do both, you can protect the Earth and protect the economy."
Last year, Schwarzenegger signed legislation that imposed the first statewide cap on greenhouse gases. The move put California at odds with the administration of US President George W. Bush, which has resisted global agreements to limit emissions.
