Mike Schroepfer, Facebook's ex-chief technology officer, will now focus on combating climate change.

In September, Schroepfer announced he would be transitioning to a part-time position as CTO, with Andrew “Boz” Bosworth replacing him as head of Facebook's hardware division. Facebook rebranded the company last fall.

Schroepfer announced on Twitter that he has officially transitioned from CTO of Meta to a Senior Fellow role, where he will continue to advise projects, particularly those related to artificial intelligence.

Schroepfer wrote on Twitter that he will allocate more time and resources to addressing the climate crisis, both as an early-stage climate tech investor and by increasing his philanthropic efforts to support early-stage scientific research.

Schroepfer highlighted a project examining the potential of the ocean to absorb carbon dioxide on a massive scale.

Few places can harness tech's potential to shape a brighter future as effectively as Schroepfer believes, according to his tweet.

Schroepfer, the CTO of Meta, announced on Facebook that he was stepping down without mentioning his plans to focus on climate change.

Another prominent Meta executive, Chris Cox, who left the company in 2019 and was later brought back as Facebook faced turmoil, has also worked on climate change issues while outside of Zuckerberg's office.

Cox collaborated with Planet, a San Francisco-based company that captures daily photos of Earth using satellites, and Watershed, another San Francisco start-up that developed software to help businesses achieve zero carbon emissions.
