Data generated during this research will resolve ongoing uncertainties surrounding a blind spot in national greenhouse gas (GHG) abatement policy and methodology. Current national and international GHG emission estimates are unable to account for N2O emissions resulting from the downstream disposal phase of the wastewater management cycle, and as a result, actual GHG emissions may be far greater than currently estimated. This research will provide primary data on the magnitude of downstream N2O emissions coming from the near-shore marine disposal of primary-level municipal wastewater in Australia. Results from this research will help quantify the carbon footprint associated with marine disposal of poorly treated effluents worldwide.

这项研究期间产生的数据将解决围绕国家温室气体(GHG)减排政策和方法盲点的持续不确定性。目前的国家和国际温室气体排放量估计数无法说明废水管理周期下游处置阶段产生的N2O排放量，因此，实际的温室气体排放量可能远远大于目前的估计数。这项研究将提供有关澳大利亚初级城市污水近岸海洋处理所产生的下游N2O排放量的初步数据。这项研究的结果将有助于量化与全球范围内处理不当的流出物的海洋处置相关的碳足迹。
