如今，严重的污染问题，其中一些与温室气体排放有关，促进了重要的尝试，以面对和减少全球变暖对墨西哥谷都市区（MVMZ）以及世界各地的大城市地区的影响。为了减少废气排放，已经进行了许多努力来重新配制燃料和设计新的催化转化器;然而，众所周知，其他变量，如社会经济和运输结构因素也在这个问题上发挥重要作用。本文分析了几种常用的三效催化转化器（TWC）和平均交通速度在温室气体N2 O排放中所起的作用。根据这项研究，通过增加平均交通流量和避免经常减速（频繁停车）在共同的行程，显着的环境和经济效益，可以获得由于减少N2 O和其他污染物的排放，如氨（NH3），甚至CO2与随之而来的减少化石燃料的消耗。上述行动在总体上减少全球变暖效应和污染问题方面是非常可行的。
Nowadays, the drastic pollution problems, some of them related with greenhouse gas emissions, have promoted important attempts to face and diminish the global warming effects on the Mexico Valley Metropolitan Zone (MVMZ) as well as on the huge urban zones around the world. To reduce the exhaust gas emissions, many efforts have been carried out to reformulate fuels and design new catalytic converters; however, it is well known that other variables such as socio-economic and transport structure factors also play an important role around this problem. The present study analyzes the roles played by several commonly-used three-way catalytic converters (TWC) and the average traffic speed in the emission of N2O as greenhouse gas. According to this study, by increasing the average traffic flow and avoiding constant decelerations (frequent stops) during common trips, remarkable environmental and economic benefits could be obtained due to the diminution of N2O and other contaminant emissions such as ammonia (NH3) and even CO2with the concomitant reduced fossil fuel consumption. The actions mentioned above could be highly viable to diminish, in general, the global warming effects and contamination problems.
