Arbor today announced a contract to deliver 25,000 tons of permanent carbon dioxide removal to Microsoft. Starting in 2027, Arbor will support Microsoft’s climate goals by delivering 5,000 tons of carbon removal per year while generating enough clean electricity to power thousands of homes.

This protocol outlines the MRV and best practices for high-quality carbon removal of CO₂ from the atmosphere via Industrial Process Biogenic Carbon Capture and Storage.

Arbor has been named a semifinalist in the U.S. Department of Energy’s Carbon Dioxide Removal Purchase Pilot Prize. The company will receive $50,000 in funding to advance its CO2 removal technology, part of a broader initiative to accelerate scalable solutions and support the growing carbon removal industry.

As a high schooler, Hartwig built a pedal-driven helicopter after reading about a human-powered helicopter competition in Popular Science. (It didn’t win.) He then went to USC for aerospace engineering, where he and his team built a rocket to go to space. (It did.) After graduating, Hartwig worked on the engines for SpaceX’s Dragon so the crew and cargo spacecraft could dock with the International Space Station. (It did, safely.)

California announced $3 million in awards to jumpstart innovative technologies like Arbor designed to convert biomass to carbon-negative energy, which will also improve forest health, reduce wildfire risk, and improve the state’s watershed in the Sierra Nevada.
