Abstract: A system for greenhouse gas emissions data collection and cross-validation, including vehicle tailpipe emissions sensor devices, mine site environmental emission sensor devices, distributed computing data interfaces installed on light- and heavy-duty vehicles, wireless connection controllers integrated with the data interface, and remote cloud data servers. The system also includes software components that include a distributed computing-level cross-validation AI algorithm. The system also includes data acquisition modules, data analysis modules and sensor data processing modules. The particular acceptability threshold is calculated either in real-time and continuously or at predetermined time intervals. Further, the emission data is benchmarked against an acceptability threshold calculated from the emissions data from similar vehicles continuously accumulated using similar processes at the same mine site and globally.
