Arnold Schwarzenegger says leaders who claim combating climate change hurts the economy are "stupid or liars".
Ahead of the COP26 climate summit, the former governor of California told the BBC that cutting carbon emissions will benefit global economies.
The Terminator actor said reducing meat intake does not have to mean sacrificing something - instead cutting his own has led him to be healthier.
He also took aim at pollution caused by international trade.
In a wide-ranging interview for BBC Radio 4's 39 Ways to Save the Planet series, Mr Schwarzenegger claimed California's continued economic success and prolific job creation proves carbon dioxide reduction and boosting wealth go hand in hand.
