280 Earth

280 Earth is a direct air capture (DAC) company that permanently removes carbon dioxide from the atmosphere. Originally launched in 2018 inside X, the Alphabet moonshot factory, and spun out as an independent company in 2022, it is backed by Sergey Brin, Builders VC and a $50M Series B. Its proprietary sorbent moves through a gravity-fed dual-chamber system that continuously cycles material between capturing and releasing CO2, running on low-grade industrial waste heat or clean electricity and producing fresh water as a byproduct. Its first pilot plant, in The Dalles, Oregon, captures 500 tons of CO2 per year on a site sized for more than 20,000 tons per year at full build-out, and underpins a $40M offtake agreement with the Frontier carbon removal buyer consortium (Google, Meta, Stripe, Shopify and others). 280 Earth is a hardware and carbon-removal operator; as of this profiling pass it publishes no public developer surface, API, or machine-readable contract.

280 Earth is profiled on the APIs.io network. Tagged areas include Company, Climate, Carbon Removal, Direct Air Capture, and Carbon Capture.
