A synthesis of new methane (CH4) emission data from a recent series of ground-based field measurements shows that 1.7% of the methane in natural gas is emitted between extraction and delivery (with a 95% confidence interval from 1.3% to 2.2%). This synthesis was made possible by a recent series of methane emission measurement campaigns that focused on the natural gas supply chain, production through distribution. The new data were translated to a standard basis, augmented with other data sources as needed, and simulated using a Monte Carlo-enabled, life cycle model. Gathering facilities and production pneumatics are the top methane emission reduction opportunities for the natural gas sector, but there are knowledge gaps and sources of uncertainty that merit further research.
