英语新闻丨中国应对一氧化二氮排放，引领变革
Episode 4
Thanks to a governance approach that combines pollution control with climate action, China has seen the growth rate ofanthropogenic emissions ofnitrous oxide level off and steadily decline since 2013. N2O is a greenhouse gas far more potent than carbon dioxide.
得益于将污染防治与气候行动相结合的治理模式，中国自2013年起已实现人为源一氧化二氮排放增速趋缓并稳步下降。一氧化二氮（N2O）是一种温室气体，其温室效应远强于二氧化碳。
China's experience shows that economic growth does not necessarily mean higher emissions of this heat-trapping gas.
中国的实践经验表明，经济增长并非必然导致这种吸热气体排放增加。
The remarks were made on Saturday by Han Yinghui, associate professor at the University of Chinese Academy of Sciences' college of resources and environment, at an event on controlling non-carbon dioxide, or non-CO2, greenhouse gas emissions. The event was held at the Chinese pavilion on the sidelines of the 30th session of the Conference of the Parties to the United Nations Framework Convention on Climate Change, or COP30, in Belem, Brazil.
上述观点由中国科学院大学资源与环境学院副教授韩颖慧于周六在一场非二氧化碳（non-CO2）温室气体减排相关活动中提出。该活动在巴西贝伦举行的《联合国气候变化框架公约》第三十次缔约方大会（COP30）期间，于中国馆举办。
"N2O is decisive for achieving our temperature goals," Han said, highlighting the importance of anthropogenic N2O emissions control.
韩颖慧指出，“一氧化二氮（N2O）减排对实现温控目标具有决定性意义”，并强调了人为源一氧化二氮排放管控的重要性。
The Paris Agreement aim is to keep global temperature rise this century below 2 C above pre-industrial levels, with efforts to limit the increase to 1.5 C. Scientists increasingly agree that keeping global warming under 1.5 C is essential to avoid severe and catastrophic impacts.
《巴黎协定》的目标是将本世纪全球气温上升幅度控制在工业化前水平以上2℃以内，并努力将升温幅度限制在1.5℃以内。科学家们日益达成共识，将全球变暖控制在1.5℃以内对于避免严重且灾难性的影响至关重要。
As the third most significant long-lived greenhouse gas, N2O has a global warming potential nearly 300 times that of CO2 and remains in the atmosphere for more than a century, Han said. Globally, most N2O emissions come from agriculture, but energy, waste, and industrial sources also contribute. While agriculture produces the largest share, industrial sources offer the greatest potential for reduction.
