This study updates and expands on the 2019 AGF assessment of renewable natural gas (RNG), which is derived from biomass or other renewable resources and is a pipeline-quality gas that is fully interchangeable with conventional natural gas. The study incorporates a revised assessment of supply potential, recent advancements in technology, and shifts in policy landscapes. The focus of the study is on assessing the volumetric potential of RNG production from diverse feedstocks and technologies, examining the broader implications for greenhouse gas (GHG) emission reductions, and analyzing the cost-effectiveness of RNG implementation across various timescales.

This report is structured across four areas: a) the national RNG production potential from various feedstocks, b) the corresponding GHG emission reduction potential, c) the estimated costs of bringing RNG supply into production, and d) the potential to reduce and/or eliminate technological barriers to RNG development.
