Chief Environmental Officer
When Microsoft announced in 2020 that it would become carbon neutral by the year 2030, the world gasped. And Lucas Joppa took on the job of making sure it would happen. He is the company’s first ever chief environmental officer, and his day job is, pretty much: Save the planet. He is perfect for the role, though. He has been an environmental scientist for Microsoft since 2017 and has a Ph. D. in ecology from Duke.
