Nitrogen oxide released from nitrogen fertilisers accumulates in the atmosphere as a green house gas that is 300 times more damaging than carbon dioxide.

由氮肥产生的含氮氧化物等温室气体进入大气后，其产生危害能力二氧化碳的三百多倍。

As this gas passes through a solution of chemicals called amines, the carbon dioxide is absorbed but the nitrogen is not.

照此方案，气体将通入一种称为氨的化学溶液，二氧化碳会被溶解吸收而氮气则不会。

Power plants that burn coal produce more than 90 times as much sulfur dioxide, five times as much nitrogen oxide and twice as much carbon dioxide as those that run on natural gas, according to the Government Accountability Office, the regulatory arm of Congress.

For important pollutants monitored by the EPA, natural gas power cuts carbon monoxide emissions by 81%, nitrogen oxide emissions by 80%, sulfur dioxide emissions by 99%, mercury emissions by 100%, and particulates by 99%.
