- Anthropogenic organic carbon emissions reporting has been largely limited to subsets of chemically-speciated volatile organic compounds. However, novel aircraft-based measurements revealed total organic carbon emissions exceeding oil sands industry-reported values by 1900-6300%, the bulk of which was due to unaccounted-for intermediate- and semi-volatile organic compounds. Measured facility-wide emissions represented approximately 1% of extracted petroleum, resulting in total organic carbon emissions equivalent to that from all other sources across Canada combined. These real-world observations demonstrate total organic carbon measurements as a means of detecting unknown or underreported carbon emissions regardless of chemical features. Since reporting gaps may include hazardous, reactive, or secondary air pollutants, fully constraining the impact of anthropogenic emissions necessitates routine, comprehensive total gaseous organic carbon monitoring as an inherent check on mass closure.
