通过比较N2O与其他臭氧消耗物质的臭氧消耗潜能加权人为排放，我们发现，N2O排放目前是最重要的单一臭氧消耗排放，预计将保持整个世纪最大的。N2O不受《蒙特利尔议定书》的管制。限制今后的一氧化二氮排放将促进臭氧层从枯竭状态的恢复，还将减少气候系统的人为强迫，这对臭氧和气候来说是一个双赢的局面。
By comparing the ozone depletion potential-weighted anthropogenic emissions of N2O with those of other ozone-depleting substances, we show that N2O emission currently is the single most important ozone-depleting emission and is expected to remain the largest throughout the 21st century. N2O is unregulated by the Montreal Protocol. Limiting future N2O emissions would enhance the recovery of the ozone layer from its depleted state and would also reduce the anthropogenic forcing of the climate system, representing a win-win for both ozone and climate.
