Natural Gas STAR Program

Methane Challenge Program Continuous Improvement Fact Sheet

Through the Methane Challenge Program, EPA encourages Partners to make ambitious commitments to reduce natural gas (methane) emissions through broad scale implementation of cost-effective technologies and practices. EPA recognizes ongoing advances in technologies and approaches for identifying, measuring, and mitigating methane emissions. To encourage innovation and technological advances, EPA will consider adopting new emission sources and/or Best Management Practices (BMPs) as commitment options under the Methane Challenge Program, as well as revising approaches to track, implement, and report on current commitments. This document outlines the process through which such updates will be proposed and evaluated.
