MetaMike Schroepfer is the former chief technology officer of the company and will now devote his efforts to combating climate change.

In September, Schroepfer announced he would be stepping down from his role to a part-time position, to be replaced as CTO by Andrew “Boz” Bosworth, who was the head of Facebook’s hardware division. Facebook changed the name of the company to Meta in September 2013.

Schroepfer posted on Twitter that Thursday that he was officially transitioning from Meta’s Chief Technology Officer to Senior Fellow, and will be continuing to provide advice for projects, primarily in the area of artificial intelligence.

Schroepfer posted on Twitter, “Outside Meta, I’ll dedicate more of my time and resources to working on climate crisis, both early stage climate technology investor and by double downing on philanthropic works to advance early-stage science research.”

Take, for example: Schroepfer pointed to a project studyingHow the ocean can be used at large to reduce carbon dioxide in the atmosphere

Schroepfer tweeted, “There’s not a place where tech could play a greater role in creating better futures.”

Schroepfer made the announcement via a Facebook postAlthough he announced that he was leaving the Meta’s CTO post, he made no mention of his intention to change his mind about climate change.

Another prominent Meta executive — Chris Cox, the social media company’s head of product, who left the company in 2019 and then was brought back as Facebook was riled in turmoil — has also worked on climate change issues when he was outside of Zuckerberg’s office.

Cox served as an advisor to Planet, a San Francisco company takes photos of the earth once every day with satellites, and he worked with Watershed, another San Francisco start-up that built software that can be used by businesses trying to get their operations to zero carbon emissions.
