Renewable Natural Gas (RNG) & Biogas
Producers and developers capturing methane from organic waste sources, upgrading it to pipeline-quality RNG, and injecting it into the natural gas grid as a low-carbon fuel.

Overview
Renewable Natural Gas (RNG) & Biogas covers the capture and upgrading of biogas from landfills, dairy and livestock manure, wastewater, and organic waste into pipeline-quality renewable natural gas. It spans RNG developers, landfill-gas projects, and the waste and agriculture companies monetizing methane that would otherwise be emitted.
Demand is driven by transportation fuel (RNG for vehicle fleets), utility decarbonization, and powerful incentives (RINs, LCFS credits, IRA support) that make RNG economics highly attractive, with dairy RNG especially valuable for its low carbon intensity. It is a fragmented, fast-growing, and heavily-invested segment, with energy majors, waste companies, and developers acquiring RNG projects and pipelines.
Market snapshot
RNG and biogas span waste, agriculture, and gas-distribution classifications and are an emerging category not separately disclosed by the Census Bureau, so the segment is not separately sized here.
