Renewable natural gas (RNG) is a fuel made by capturing methane released from organic waste—like landfills, farms, or wastewater—and cleaning it so it can replace conventional natural gas. Think of it as recycled gas: it turns waste into a usable energy product that can be sold, piped, or used as vehicle fuel. Investors care because RNG projects create predictable revenue streams, often qualify for subsidies or carbon credits, and reduce regulatory and market risk tied to emissions, affecting long-term cash flow and asset value.
anaerobic digesterstechnical
Anaerobic digesters are sealed systems where microbes break down organic material such as food waste, manure or crop residues without oxygen, producing biogas (mainly methane) and a nutrient-rich residue. They matter to investors because they convert waste into sellable energy and fertilizer, lower disposal costs and emissions, and can provide steady revenue from electricity or fuel sales, renewable credits, and byproduct markets — like turning trash into a small power plant and fertilizer source.
methanetechnical
Methane is a colorless, odorless gas that is the main component of natural gas and is produced both naturally (from swamps, wetlands) and by human activity (fossil fuel production, agriculture). Investors care because methane is a potent greenhouse gas that can trigger tighter regulations, cleanup costs, or liability, and it also links directly to energy supply and prices—think of it as a hidden leak that can affect both a company’s costs and its regulatory risk.
Renewable Identification Numbers (RINs)regulatory
Renewable Identification Numbers (RINs) are unique tracking credits used under U.S. renewable fuel rules to prove that a gallon of transportation fuel contains an approved amount of biofuel. Think of them as tradable coupons that biofuel producers and fuel blenders earn, buy, or sell to show regulatory compliance; their price and availability directly affect the cost and profit of companies involved in fuel production, refining, and distribution, creating financial exposure and potential revenue streams for investors.
Renewable Fuel Standard (RFS)regulatory
A renewable fuel standard (RFS) is a government rule that requires a certain portion of transportation fuel to come from renewable sources like biofuels, and it creates a system of tradable compliance credits to enforce those targets. It matters to investors because the RFS changes demand, pricing and profit margins across fuel producers, refiners, farmers and makers of renewable fuels, creating both regulatory risks and market opportunities similar to a store being required to stock a fixed share of eco-friendly products.
Low Carbon Fuel Standard (LCFS)regulatory
A low carbon fuel standard (LCFS) is a government rule that assigns value to fuels based on how much greenhouse gas they emit over their life cycle, rewarding cleaner alternatives with tradable credits and penalizing dirtier fuels. For investors, it creates a market signal that can raise demand and profits for low‑emission fuel producers, change operating costs for refineries and transport companies, and influence the economics of projects much like a price on pollution or a reward program for cleaner choices.
greenhouse gas (GHG) emissionstechnical
Greenhouse gas (GHG) emissions are gases released into the atmosphere—most commonly carbon dioxide, methane and nitrous oxide—that trap heat and raise global temperatures, like a blanket warming the planet. Investors watch GHG emissions because they influence regulatory costs, physical climate risks, insurance and supply-chain stability, and public reputation; companies with lower emissions may face fewer future expenses and attract more capital, while higher emissions can lead to fines, disruption or divestment.
carbon-intensitytechnical
Carbon-intensity measures how much greenhouse gas a company or activity emits for each unit of output — for example per dollar of revenue, per megawatt-hour of electricity produced, or per product made. It matters to investors because it shows how polluting and energy-inefficient a business is, which affects future costs, regulatory risk, and reputation; think of it like miles-per-gallon for emissions rather than fuel efficiency for a car.

NEWPORT BEACH, Calif.--(BUSINESS WIRE)--
Clean Energy Fuels Corp. (NASDAQ: CLNE) has announced it has completed its eighth dairy renewable natural gas (RNG) production facility in Jerome, Idaho – one of the largest single-site dairies and RNG facilities in North America. East Valley Cattle has now begun producing and injecting negative carbon-intensity RNG into the interstate pipeline which will be used as clean fuel for transportation fleets across the country.
Clean Energy’s renewable natural gas (RNG) facility at East Valley Cattle, Jerome, Idaho.
Home to over 35,000 cows, the East Valley RNG facility has six anaerobic digesters which are designed to capture methane from cow manure, preventing harmful emissions from entering the atmosphere.
The facility can take in over 5 million gallons of manure each day using a municipality-scale wastewater treatment system and advanced manure separation technology to process and clean the manure. This unique approach ensures maximum efficiency and sustainability for a dairy of this size before moving to the anaerobic digestion process which produces clean, pipeline-quality RNG. The byproducts are then reused onsite to support farm operations, providing bedding for livestock and crop fertilizer.
“This is probably the most ambitious project we’ve taken on – the scale, the technology, and the integration of systems are unmatched and quite frankly, extremely impressive,” said Will Flanagan, Vice President of Strategic Development at Clean Energy. “We’re capturing methane, cleaning it up and injecting it on-site while replacing natural gas that would have been of fossil origin. It’s a double offset renewable energy, and we are proud to be a part of it.”
In the first quarter of 2026, the East Valley Dairy project recognized its first revenue, and the RNG produced received full approval from the U.S. Environmental Protection Agency (EPA) to begin generating Renewable Identification Numbers (RINs) under the Renewable Fuel Standard (RFS) program and from the California Air Resources Board (CARB) to generate California Low Carbon Fuel Standard (LCFS) credits. This project has been financed through CE bp Renew Co, Clean Energy’s joint venture with bp.
Agriculture accounts for nearly 10 percent of U.S. GHG emissions and the transportation sector accounts for another 28%, according to the EPA. Capturing methane from farm waste lowers these emissions. RNG, produced by that captured methane and used as a transportation fuel, significantly lowers GHG emissions on a lifecycle basis when compared to diesel. This allows RNG to be one of the only fuels to receive a negative carbon-intensity score based on the reduction of emissions at the source and at the vehicle and costs significantly less than diesel at the pump.
