About Us

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

Zerosix Satellite 10 S

At ZeroSix, we are scaling a digital solution for a new era of high-quality carbon credits. And we’re starting at the source: with the fossil fuels that account for the vast majority of greenhouse gas (GHG) emissions.

In a net-zero world, the most valuable barrels of oil and cubic feet of natural gas are those that remain in the ground—never extracted and never burned. We’re tapping into the power of voluntary carbon markets to permanently close wells and convert their shut-in reserves into carbon credits.

For 150 years of the modern oil and gas industry, the focus has been on surfacing, refining, and burning fossil fuels as the foundation of energy and economic prosperity. The evolution of modern renewable energy technologies such as solar PV and wind, plus the growing urgency of the climate crisis, mean that the next century and beyond of energy prosperity can and must look very different from the fossil-fueled growth the world has known until now.

Founded by fossil fuel industry veterans, we understand that the oil and gas industry needs to pivot to become part of the climate solution. That’s why ZeroSix was born.

The Story Behind Our Name

Our name — ZeroSix — is a reference to the net-zero future we are all creating together.

A net-zero world aligned to the 1.5ºC target of the Paris Agreement requires addressing both carbon dioxide (CO2) and methane (CH4). CO2 is the most abundant and longest-lived of human-caused greenhouse gases, while CH4 is a potent short-lived climate pollutant.

The common denominator between them is carbon, the sixth element on the Periodic Table. A net-zero future must therefore also be a zero-carbon future. The name ZeroSix keeps that mission always in focus.
