利用2026年夏季卫星观测，量化中国三个己二酸生产厂的一氧化二氮排放，年排放超五十万吨，表明减排有限，消除这些排放相当于消除美国49座燃煤电厂或4300万辆燃气汽车的年排放。
AI 中文摘要
己二酸的生产过程中会产生一氧化二氮作为副产品，如果排放到大气中，会非常有效地加剧气候变暖并消耗平流层臭氧层。目前已有成本效益高的技术来减少己二酸生产过程中的一氧化二氮排放，但该技术的实施程度，尤其是在中国的工厂，仍不确定。利用2026年夏季的卫星观测数据，我们量化了中国三个己二酸生产厂的一氧化二氮排放量，发现年排放总量超过五十万吨，这一速率表明减排措施有限。就气候变化而言，仅消除这三个工厂的年排放量，相当于消除美国49座燃煤电厂或4300万辆燃气动力汽车的年排放量。
英文摘要
The production of adipic acid generates nitrous oxide as a by-product, which, if emitted, very effectively warms the climate and depletes the stratospheric ozone layer. There exists cost-effective technology to mitigate these nitrous oxide emissions from adipic acid production, but the degree of implementation of this technology, most notably at sites in China, is uncertain. Using satellite observations from summer 2026, we quantify nitrous oxide emissions from three adipic acid production sites in China, finding emissions that total over half a million tonnes per year, a rate that implies limited emissions abatement. With respect to climate change, eliminating the annual emissions from just these three sites would be equivalent to eliminating the annual emissions from 49 coal-fired power plants or 43 million gas-powered vehicles in the United States.
