Description
This report provides a detailed review of current and emerging technologies used to detect and quantify methane emissions from landfills in North America. The analysis includes over a dozen monitoring systems, categorized by platform type (e.g., walking surveys, mobile platforms, UAVs, aircraft, and satellites), sensor technology, and post-processing methods.
The report was developed to support waste sector professionals, regulators, and researchers seeking to improve methane measurement practices. It addresses the limitations of traditional surface emission monitoring (SEM) methods and compares newer approaches based on factors such as accuracy, minimum detection limit (MDL), quantification capability, technology readiness, and operational constraints.
Included are findings from recent controlled-release testing, such as the 2023 and 2024 EREF-FluxLab studies, which benchmark the performance of select technologies under field conditions. The synthesis section offers a comparative overview to help inform selection of monitoring approaches based on site-specific needs and policy contexts.
This report is intended to inform operational decision-making, regulatory development, and investment in landfill methane mitigation strategies.
