CALGARY, Alberta, June 08, 2026 (GLOBE NEWSWIRE) — What started with a single liquid nitrogen tank in the field has transformed routine oil and gas operations. Kathairos’ nitrogen systems have now directly eliminated one million metric tonnes of CO2 equivalent— and counting.

Kathairos Solutions has crossed a major climate milestone: one million metric tonnes of CO₂e eliminated.

To put that in perspective: Kathairos now eliminates more methane in one single day than many companies or technologies celebrate in an entire year— the daily equivalent to over 20,000 trees planted. The solution is currently eliminating ±1,250 tCO₂e per day with 3,000 liquid nitrogen systems deployed across North America. Every tonne is direct, attributable, independently verifiable and calculated at a conservative Global Warming Potential of 28:1.

This milestone reflects the decision of over 70 oil and gas companies to replace methane (a potent greenhouse gas) with nitrogen (a clean, inert gas) to power their facilities. From the Montney to the Permian, these operators – armed with Kathairos’ nitrogen-based technology – have set a new standard for what pneumatic actuation should look like, without compromising operational performance. Nitrogen’s success demonstrates that the simplest solution is usually the best one.

The elegance of the Kathairos system has always been its simplicity — no external power, no moving parts, no disruption to existing operations. Nitrogen simply powers the devices previously actuated by natural gas (methane). That practicality is why it has scaled so successfully across the industry.

Methane is more than 80 times more potent than CO₂ over a 20-year horizon. Pneumatic venting is among the most persistent and widespread sources of it in the oil and gas industry, occurring at hundreds of thousands of facilities across North America. Kathairos’ one million tonnes milestone demonstrates that these devices can be addressed at scale.

The data behind that number matters. Every Kathairos system transmits hourly data to Atlas, the company’s operator-facing platform, giving customers real-time, site-specific visibility into exactly how much methane their sites are eliminating. It’s turned methane elimination from a compliance checkbox into something operators can quantify and be proud of.

Dick Brown, CEO and Founder, started Kathairos in 2020 with a conviction that the oil and gas industry would address pneumatic venting if there was an affordable solution that worked in the field. One million tonnes is a testament to this vision. The company is just getting started—as more sites convert to nitrogen, methane emissions decrease exponentially.
