Amazon founder Jeff Bezos says he plans to give away most of his $124 billion dollars fortune during his lifetime.
The businessman told news network CNN he would donate his wealth to fighting climate change and reducing inequality.
He has previously been criticised for not promising to dedicate his fortune to charity.
Investor Warren Buffett, Microsoft founder Bill Gates and Mr Bezos’s ex-wife MacKenzie Scott have all promised to give their money away.
Mr Bezos revealed his plans after donating $100 million dollars to the country music star and philanthropist Dolly Parton to use for charitable causes.
Asked by CNN whether he intended to give away most of his wealth within his lifetime, Mr Bezos told the network: “Yeah, I do.”
