Renewable Natural Gas

Where the gas is greener


Active for over a decade, Anew’s RNG team is North America’s leading full-service biomethane marketing group. RNG can replace fossil fuel in any natural gas application, including powering vehicles, generating power, and heating homes. We partner with farmers, landfill operators, and wastewater treatment plants to generate renewable fuel and bring it to market for utilities, fleet operators and voluntary buyers seeking cleaner energy.

We are your guide from generation to monetization of environmental credits, allowing you to take full advantage of premium markets while minimizing execution risks.

RINS and LCFS Credits

Renewable Identification Numbers (RINs) and Low Carbon Fuel Standard (LCFS) credits for compliance must meet rigorous standards to reduce revocation risk. In addition to our expert due diligence, independent third-party verification is also offered on many products.

A lever for climate progress

Methane's impact

Landfills, wastewater, manure, and other operations generate high volumes of raw biogas. If the methane contained in biogas is allowed to escape into the atmosphere, the global warming impact is more than 28 times higher than the equivalent amount of carbon dioxide.


Closing the loop on waste

Energy transformed

Capture and purification of the methane portion of raw biogas transforms it into a clean-burning, renewable, pipeline quality fuel that is much less carbon-intensive than fossil-derived natural gas while still able to leverage North America's expansive natural gas grid. This allows us to deliver RNG to any location currently utilizing natural gas today.


Available Project Types


Large agricultural operations such as swine and dairy farms emit methane-rich gas that can be captured, purified and upgraded to pipeline quality renewable fuel.


Landfill gas projects collect biogas that is produced from anaerobic digestion of waste produced through natural processes occuring in every landfill.


Wastewater treatment plants are among the most efficient methods for preventing methane emissions and converting waste products into important GHG reduction tools.

Understanding Renewable Natural Gas

Common questions

The carbon intensity (CI) score analyzes greenhouse gas emissions for the entire pathway of the renewable fuel’s lifecycle, from feedstock collection through to conversion, upgrading, transportation and distribution into the energy pipeline. By assessing all the carbon emitted along the supply chain for any given renewable fuel and comparing that with a reference fossil fuel that is being replaced, a CI score is assigned. A low or an increasingly negative CI score indicates the renewable fuel achieves a greater avoidance of harmful emissions as compared with the reference fuel being replaced and as such is considered more valuable fuel. Anew has a sizable portfolio of RNG with highly-desirable, low CI scores.

According to the EPA, decomposing waste such as agriculture waste accounts for 26% of US methane emissions. RNG captures and repurposes methane from waste before it escapes into the atmosphere. When produced following best practices that maximize methane avoidance, RNG results in meaningful net carbon reductions, and those are the projects we are helping to bring to the market.

RNG projects improve handling of waste, reduce odor around project sites, decrease nutrient loading in waterways, and increase economic opportunities. These projects take existing waste streams and make them part of the circular economy—generating renewable energy, improving air quality around project sites, and creating jobs.

RNG’s advantage is its on-demand capability—it can be supplied 24/7, it’s base-loadable, it is not weather-dependent, and it can be stored. In addition to its use as a transportation fuel, it can produce renewable electricity and is deployable for thermal uses. RNG is also a direct path to reducing Scope 1 thermal emissions now, while work progresses in building out electrification and hydrogen infrastructure.
