About Us

We’re solving the net-zero emissions challenge of what’s above, by focusing on what stays below.

For 150 years of the modern oil and gas industry, the focus has been on surfacing, refining, and burning fossil fuels. The next era of fossil fuel 'prospecting' is focused on the dual economic and climate opportunity of 'harvesting' unburned oil and natural gas.

Our platform and strict protocol — rooted in accuracy, additionality, permanence, and transparency — unlocks a pathway for oil & gas producers to take a substantial role in the climate action solution, while giving voluntary carbon market buyers the confidence to invest.

We’re introducing the world to a revolutionary new kind of carbon credit—an upstream carbon offset rooted in fossil fuels that never burn, by incentivizing producers to shut wells early and turn unburned oil and gas into high-integrity carbon credits.
