人为有机碳排放报告主要限于化学物种挥发性有机化合物的子集。然而，新的基于飞机的测量结果显示，总的气相有机碳排放量超过油砂行业报告的值1900%至6300%以上，其中大部分是由于不明的中间挥发性和半挥发性有机化合物。测量的设施范围内的排放量约占开采石油的1%，导致总有机碳排放量相当于加拿大所有其他来源的总和。这些真实世界的观测表明，总有机碳测量是检测未知或漏报的碳排放的一种手段，无论其化学特征如何。由于报告差距可能包括危险性、反应性或二次空气污染物，因此充分限制人为排放的影响需要进行常规、全面的总有机碳监测，作为对大规模关闭的内在检查。
Anthropogenic organic carbon emissions reporting has been largely limited to subsets of chemically speciated volatile organic compounds. However, new aircraft-based measurements revealed total gas-phase organic carbon emissions that exceed oil sands industry–reported values by 1900% to over 6300%, the bulk of which was due to unaccounted-for intermediate-volatility and semivolatile 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. Because reporting gaps may include hazardous, reactive, or secondary air pollutants, fully constraining the impact of anthropogenic emissions necessitates routine, comprehensive total organic carbon monitoring as an inherent check on mass closure.
