A system and method for a remotely deployable, off-grid system to autonomously detect, quantify, and automatically wort emissions of methane (CH.sub.4) and other gases to the atmosphere, Automated CH.sub.4 emissions detection is accomplished by the use of commercially available CH.sub.4 sensors. CH.sub.4 accuracy is maximized by simultaneously measuring, and accounting for, undesired CH.sub.4 sensor response from interfering gases such as carbon monoxide (CO) and water vapor (H.sub.2O), and undesired CH.sub.4 sensor response from ambient temperature (T) changes. Automated CH.sub.4 emissions quantification is accomplished by calculating a leak rate (mass or volume per unit time) from the measured concentration enhancements using simultaneous measurements of wind speed and direction. Automated CH emissions reporting is accomplished following transmission of measured CH.sub.4concentrations via cellular wireless, radio, or satellite link to a central cloud-based server. Remote off-grid operation is accomplished by solar, wind, or other renewable energy source(s) that charge an on-board battery. This system offers a robust, unattended, and continuous CH.sub.4 monitoring and reporting capability to permit improved accuracy and efficiency of CH.sub.4 leak detection and repair (LDAR) from sources located in remote areas without electrical power, e.g., leak detection at well pads and processing facilities in oil and gas production areas, at concentrated animal feeding operations, and other methane sources.
