Warren Buffett has pledged to give away 99% of his wealth to philanthropic causes. Approximately 83% of that will go to the Bill & Melinda Gates Foundation and much of the rest will be distributed to the foundations of his children. He is a very hands-off philanthropist, preferring to entrust his wealth to those he knows will spend it wisely on worthwhile philanthropic causes. Buffett has pledged 10 million shares of Berkshire Hathaway Class B stock to the Gates Foundation over a period of years.
In addition to supporting the Gates Foundation, Buffett has pledged Berkshire Hathaway stock to each of his children's foundations, worth more than $2 billion each. These foundations include Peter and Jennifer Buffett's NoVo foundation, which seeks to empower adolescent girls and end violence against women; the Howard G. Buffett Foundation, which focuses on food and water security, conflict mitigation, endangered mammal conservation, and local community support; and Susan Buffett's Sherwood Foundation, which focuses on early childhood education both in Nebraska and nationally and on rural and urban community development in Nebraska.
