MacKenzie Scott, the ex-wife of Jeff Bezos, said Tuesday she has donated nearly $1.7 billion to more than 100 charitable organizations following her divorce from the Amazon founder last year.

Scott wrote in a lengthy blog post that she was troubled by the events of this year but had worked with a group of advisers to support nonprofits linked to human rights, environmental and social causes. The move comes after she signed the Giving Pledge, a public promise among the world’s richest people to donate at least half of their wealth throughout their lifetimes.

All of the donations were unrestricted unless groups asked otherwise, Scott noted, in order to provide organizations with “maximum flexibility.”
