MacKenzie Bezos has promised to give at least half of her fortune to charity, just months after finalizing her divorce from the world’s richest man, CNN reports.
The newly minted billionaire has signed the Giving Pledge, which encourages the world’s richest people to dedicate a majority of their wealth to charitable causes, either during their lifetimes or in their wills.
The initiative was launched by Warren Buffett and Bill and Melinda Gates in 2010 and has so far attracted the support of 204 individuals and families.
MacKenzie Bezos became one of the richest people in the world following her divorce from Amazon founder Jeff Bezos earlier this year. She ranks 22nd on the Bloomberg Billionaires Index.
Her personal fortune is now worth an estimated $36.6 billion. Her former husband leads the global rankings with a net worth of roughly $114 billion.
MacKenzie Bezos said in a letter announcing the move that “I have a disproportionate amount of money to share.”
“My approach to philanthropy will continue to be thoughtful. It will take time and effort and care. But I won’t wait. And I will keep at it until the safe is empty,” she said in the letter, which was dated May 25 and published last week.
