The Giving Pledge

The Giving Pledge is a charitable campaign, founded by Bill Gates and Warren Buffett, to encourage wealthy people to contribute a majority (i.e. more than 50%) of their wealth to philanthropic causes. As of June 2022, the pledge has had 236 signatories from 28 countries. Most of the signatories of the pledge are billionaires, and as of 2023, their pledges are estimated at a total of US$600 billion. However, there is no enforcement mechanism (signing the letter is an intention, not a formal commitment), and no restrictions on the charitable causes that signatories are allowed to support.
