Her charitable contributions make good on her signing of The Giving Pledge in May 2019, vowing to donate most of her wealth to philanthropic causes over her lifetime. She wrote -- under MacKenzie Scott, the name she now uses -- that the $1.7 billion was distributed across organizations committed to racial and gender equity, economic mobility, public health, climate change and more.
Scott said she enlisted a team of nonprofit advisers with representation from marginalized communities to help her identify the most effective charities to fund.
"I began work to complete my pledge with the belief that my life had yielded two assets that could be of particular value to others: the money these systems helped deliver to me, and a conviction that people who have experience with inequities are the ones best equipped to design solutions," she wrote, explaining her process.
Donation recipients include Black Girls Code, an organization that works to increase the number of women of color in the digital and computing fields, Howard University, a historically black university, and The Trevor Project, a national crisis-intervention organization for LGBTQ young people, among other organizations.
In total, Scott said she contributed nearly $600 million in unrestricted funds to racial equity causes and nearly $400 million to economic mobility initiatives. She also gave:
$133 million to gender equity causes
$130 million to global development
More than $128 million to public health causes
$125 million to climate change groups
$72 million to "functional democracy" causes
$46 million to LGBTQ equity causes
$55 million to causes related to "empathy & bridging divides"
"I gave each a contribution and encouraged them to spend it on whatever they believe best serves their efforts," she wrote.
Scott's former husband, Jeff Bezos, is the richest person in the world, with a net worth of more than $170 billion.
Scott, 50, is believed to be the third-richest woman, with a net worth of $36 billion, according to Forbes. Most of her wealth comes from her 4% stake in Amazon, which was part of her divorce settlement.
