Description
An accurate methane measurement may capture emissions at a particular moment without reliably representing emissions over time. Measurement frequency, timing, and sampling design all influence how confidently individual observations can be used to estimate annual landfill methane emissions.
This EREF Executive Brief summarizes key findings from EREF Insights: Why Measurement Frequency Matters in Estimating Landfill Methane Emissions and presents four questions for evaluating methane estimates: instrument accuracy, sampling frequency, temporal representativeness, and uncertainty. Designed as a practical reference for landfill operators, researchers, regulators, and other decision-makers, the brief provides a framework for interpreting monitoring results, understanding method limitations, and assessing the information used to support operational, regulatory, and policy decisions.
