Google announces deal with direct-air capture startup to remove carbon emissions

Google announced that it has entered a partnership with Holocene to support its direct-air capture technology for collecting and removing carbon dioxide emissions from the atmosphere. Under this $10 million deal, Google will purchase carbon removal credits from Holocene at a rate of $100 per metric ton. This is the price the US Department of Energy set as a goal for direct-air capture technology to make it a viable part of efforts to reduce the rate at which we emit carbon dioxide into the atmosphere.

As the name implies, direct-air capture can collect carbon dioxide out of the air, then concentrate the gas to be stored in underground reservoirs. It sounds great in theory, but the technology has proven expensive and difficult to scale. Google said its support should allow Holocene to capture and store 100,000 tons of carbon dioxide from the atmosphere by the early 2030s, in addition to helping the company further refine its DAC technology. Holocene has a more detailed explanation of its DAC approach on its website.

Sustainability has become an important talking point for a lot of big tech. Google has made a big investment in buying carbon offsets, enough that it claims to have eliminated its entire "carbon legacy," and it aims to be carbon neutral by 2030. But its greenhouse gas emissions have risen almost 50 percent in the past five years thanks to the intensive data center demands of AI usage.
