A Comprehensive Guide to 2025 Subpart W Updates
The EPA has introduced significant updates to Subpart W for the 2025 reporting year (submitted in 2026), reshaping how emissions are reported and measured. These changes emphasize transparency, accuracy, and […]
Measurement-Informed Inventories Guide
A measurement-informed inventory (MII) is a refined emissions inventory that integrates bottom-up calculated emissions data with various scales and types of measurement. This iterative reconciliation process evolves as you acquire […]
State of Methane Emission Detection and Measurement Technologies for Offshore Oil and Gas Applications
For years, the common assumption was that offshore oil and gas platforms are not large sources of methane emission, partly because of the safety hazards of natural gas emissions and the high safety standards followed on these platforms. However, recent studies show that methane emissions from offshore oil and gas production are often more than those reported in
inventories.
Advanced Continuous Emissions Monitoring (CEM) Guide
Abstract: Continuous emissions monitoring is a rigorous approach to finding andresolving methane leaks faster than any other method, such as episodicaerial flyovers, quarterly OGI camera inspections, or audio-visual olfactoryinspections. This […]
