Are you a Subpart DD reporter?

See this page to learn more about greenhouse gas reporting rules (GHGRP), applicability, trainings, and reporting system access. Subpart DD specific information is also available.

State and Regional Regulatory Information

While EPA works with the electric power industry to promote best practices and technologies to voluntarily reduce SF6 emissions, other regulatory efforts exist at the federal, regional, and state level to monitor and/or reduce SF6 and other insulating gas emissions.

Learn more about these efforts.

Research and Case Studies

The research and studies below provide additional information on the topic of SF6 emissions in electric power systems.
