Jeff Bezos committed $10 billion to climate action in 2020 with a 2030 deadline, and his wife Lauren Sánchez Bezos, now vice chair of the Bezos Earth Fund, has become the public face of the fund's spending push over the past year—announcing $37.5 million for Pacific island marine protection, $30 million for AI climate solutions, and accelerating deployments across multiple environmental initiatives. The fund has deployed $2.3 billion of the $10 billion commitment so far, leaving roughly $7 billion to spend in less than four years as the deadline approaches. What gets less attention: MacKenzie Scott, Bezos's ex-wife, has donated $26 billion to charity in the same period—well over half her net worth—and gave $7.2 billion in 2025 alone, dwarfing Bezos's lifetime charitable giving of roughly $4.7 billion despite his $268 billion net worth.
