Dairy RNG: the most carbon-negative fuel on the market
Most fuels add greenhouse gas to the atmosphere. Dairy RNG starts by keeping it out. On a dairy without a digester, manure lagoons emit methane — a greenhouse gas with roughly 28 times the warming effect of CO2 over a century, and far more over the next two decades. A digester captures that methane before it reaches the atmosphere, cleans it to pipeline quality, and puts it to work as fuel. The climate benefit comes twice: once from the emission that never happened, and again from displacing fossil natural gas.
California's Low Carbon Fuel Standard (LCFS), administered by the California Air Resources Board (CARB), scores every fuel on its full lifecycle carbon intensity — production, transport, and combustion. Because the avoided methane counts against the fuel's footprint, certified dairy RNG pathways score below zero. Not low-carbon. Negative. Dairy and livestock RNG pathways carry the lowest certified carbon-intensity scores of any fuel in the program — lower than grid electricity, and lower than solar or wind on the same lifecycle accounting, because those technologies avoid new emissions, while dairy RNG captures a potent greenhouse gas that was already being released.
An honest caveat: carbon intensity is certified per project pathway, based on measured operations, not claimed as a blanket number. When you work with us, the score attached to your gas or your attributes is the score CARB certified for the specific digester that produced it.
Two ways to work with us
Physical RNG supply. Pipeline-quality renewable natural gas, chemically interchangeable with the fossil gas your equipment already burns — no retrofits required. It can fuel on-site power generation, backup generators, gas-driven cooling, and process heat. Where pipeline interconnection works, gas is delivered under contract through the grid. Where it doesn't, our hauling division operates a virtual pipeline — RNG and CNG moved by tanker, a capability we already run at scale alongside more than 12,000 tanker loads per year.
Environmental attributes. Sometimes the molecule can't physically reach your facility, but the climate benefit still can. Every unit of RNG we produce carries measurable environmental attributes, tied to metered production and the methane it kept out of the atmosphere. Working with our partners, we structure those attributes so they are retired in your name and count toward your footprint goals — the same book-and-claim logic behind renewable electricity certificates, applied to gas. The gas itself displaces fossil fuel wherever it enters the system; the verified benefit belongs to you and no one else.
Why data centers
- Power demand is outrunning clean supply. New capacity is hard to site and slow to interconnect. RNG-fueled generation is dispatchable — it runs when you need it, not when the weather allows — and can be deployed on-site or near-site.
- Backup generation is a footprint blind spot. Diesel gensets are a standing carbon and air-quality liability. Natural-gas generators running on RNG turn the backup fleet from a reporting problem into a much lower-carbon asset.
- Heat and cooling are gas-friendly loads. Gas-driven chillers, absorption cooling, and combined heat and power all run on RNG today, with no technology risk.
- Residual emissions need credible answers. After efficiency and renewable electricity, most footprint targets still leave a gap. Verified attributes from avoided dairy methane are among the most defensible instruments available to close it.
Verified and traceable
Every claim we make rests on measurement, not estimates. Each digester project is certified under a CARB LCFS fuel pathway: production is metered, operational data is reported, and the resulting carbon-intensity score is subject to independent third-party verification and CARB review. Attributes are tied to specific metered volumes from specific projects, and each one is retired exactly once — claimed for you means retired for you. We won't claim what we can't measure, and we won't let the same benefit count twice. If your reporting framework requires documentation, chain-of-custody records, or auditor access, that's a normal part of how we do business.
Our production base
Our gas comes from real, operating digesters on Central Valley dairies — not a development pipeline on paper. We have been running digesters day in and day out since 2022, we built one of the largest lagoon digesters in the state, and our projects have earned multi-million-dollar grants from California's dairy digester program. Our gas moves under long-term offtake agreements with major energy buyers — the kind of long-horizon commitment that tells you the supply is durable. We come from a dairy family ourselves, and we build, own and operate as a licensed EPC: the projects behind your gas are ours from the ground up.
