Microsoft announced plans to become "carbon negative" by 2030, seeking to erase its entire carbon footprint since the company's founding in 1975 and begin removing more carbon from the environment than it emits.
The company first wants to reduce emissions to zero across its entire supply chain by 2030, and then focus on eliminating all of the carbon dioxide it has ever released by 2050, reports The Verge.
Microsoft has been carbon neutral since 2012, and achieves this through purchasing renewable energy and carbon offsets. Going negative will require more technology and investment than going neutral. "Technology does exist that does this, but getting the price and the scalability to where we need it to be is a significant challenge," said Lucas Joppa, the company's chief sustainability officer, per CBS News. The company plans to spend $1 billion over the next four years on carbon reduction, capture, and removal.
California Gov. Jerry Brown (D) signed legislation solidifying the goal Monday. The bill also requires California to rely on wind, solar, and other renewable sources for 60 percent of its energy consumption by 2030.
