![]() History of Considering Biomethane Certificates Under the GHG Protocol Scope 2 Guidance (2015) ![]() In some markets, contractual instruments have been introduced as a means for customers sourcing gas from common carrier pipelines to claim attributes from a differentiated source, e.g. Common carrier pipelines can contain a mix of biogenic and fossil gas. Lifecycle emission sources can include upstream land impacts, processing, transportation/distribution, and combustion.Įnergy users generally receive gas from a common carrier pipeline rather than a dedicated pipeline. Each pathway has unique lifecycle emissions, depending on the specific source and lifecycle of the fuel. Biomethane can be produced from biogas captured from degradation within a variety of systems, including manure lagoons, landfills, anaerobic digesters, or wastewater. ![]() Background: What is Biomethane?īiomethane (also known as renewable natural gas or RNG) is a form of biogenic gas that has been treated to be used interchangeably with fossil-derived natural gas. In the absence of guidance, companies purchasing certificates may wish to consult with their auditors and consider rules provided by relevant target-setting programs or applicable regulatory schemes in their jurisdiction(s) on how to report these purchases in their reports, while ensuring full transparency and following all GHG accounting and reporting principles. In the meantime, there is no definitive guidance on this question under the GHG Protocol. It explains the history of considering this issue under the GHG Protocol and explains a process to consider the use of biomethane certificates in the future. This communication provides an interim update on the treatment of biomethane certificates under the GHG Protocol.
