Two companies are accelerating carbon dioxide removal (CDR) purchases with a recent transaction announcement. Lithos Carbon – an agricultural carbon removal company developing an enhanced rock weathering solution and Carbonx Climate – a carbon credits procurement and management partner, assisting clients in achieving their net zero goals, announced a purchase of 3,000 tons of carbon removal on behalf of Carbonx’ partners.

Companies around the world are spreading crushed rocks on farms to remove carbon dioxide from the atmosphere in a process called enhanced weathering, but the hard part is measuring how much is stored

Rocks can pull carbon out of the air more inexpensively than machines. But can the process be scaled?

One carbon removal method uses giant fan-like devices to pull carbon from the air.

From ships powered by food waste to jet fuel made from CO2, here’s the climate tech we’re most excited about.

Frontier buyers will pay Lithos $57.1 million to remove 154,240 tons of CO₂ between 2024 and 2028.

Frontier, an advance market commitment to speed up carbo removal, has just made its largest carbon removal purchase from Lithos Carbon. The initiative has agreed to pay Lithos Carbon, a CO2 removal company specializing in enhanced rock weathering, a total of $57.1 million to remove 154,240 tons of carbon dioxide.

The idea of sprinkling rock dust on farmland to soak up atmospheric carbon will be tested at large scale, thanks to a $57 million purchase from corporations including Stripe and Alphabet.

The startup spun out of academic research at Yale less than two years ago. Now it’s working with more than 80 farms in nine states. And in a new deal, buyers including Stripe, Alphabet, and Shopify have committed to pay the startup $57.1 million to remove 154,000 tons of CO2 over the next four years.

The Frontier Fund, a corporate buyers’ group including Alphabet, H&M, JPMorgan, Shopify and Stripe, this week announced a $57.1 million contract with startup Lithos Carbon, which is developing a method for removing carbon dioxide from the atmosphere by spreading crushed rock on soil.

A Stripe-led group that buys carbon removal services has made its biggest bet yet on a small startup that uses crushed rocks to clean the atmosphere.

Stripe, Alphabet, Shopify, and a slew of other companies plan to spend more than $57 million cumulatively to fight climate change by spreading crushed rock over farmland.

Farming with Rockdust: a meaningful climate solution
