The Gas Technology Institute has introduced a Differentiated Gas Initiative, a program designed to accelerate the growing importance of emissions-based differentiation. The initiative is designed to create a standardized framework for measuring methane emissions throughout the natural gas value chain.

In addition, the initiative will develop measurement protocols and establish a training program for auditors to assess companies. The term “differentiated” refers to gas that has a verified and minimized emissions footprint.

Other names for the same technology include “certified,” responsible,” and “green,” natural gas. The assessment criteria to differentiate gas are generally focused on methane emissions but can consider additional qualities such as other air emissions, water use, water quality, land use of community engagement.

Differentiated gas may be evaluated throughout the value chain components of its sourcing, transportation, or delivery to customers. Ultimately, the successful scaling of differentiated gas will require standardized criteria that includes measurement, transparent reporting and verification across the natural gas value chain.

The GTI said the initiative is the result of market needs from natural gas producers, transporters, distributors, and investors. The entire value chain of natural gas will benefit from a transparent, credible approach to emissions-based differentiation of natural gas. That value chain will serve as a reference point from which a broad set of interests can work to reduce emissions, the organization said.

“Customers, investors, and other stakeholders expect energy companies to reduce the environmental impact of their operations and of the products they provide. Natural gas is no exception,” said GTI President and CEO David C. Carroll. “GTI is uniquely positioned to lead the differentiated gas effort. We have the requisite technical and operational expertise to guide this process, and a strong record of technical independence.”

The Differentiated Gas Initiative will require diverse participation, financial support, and technical input. GTI invited companies and organizations to participate and asked them to contact Erin Tullos ( if they want more information.
