چکیده
In India, the ambient air quality has been degrading from past few decades especially in urban areas. Vehicular emissions are amongst one of major reasons for deterioration such This article is an effort to review vehicular emission standards countries (USA, Europe, Japan and Australia) compare with Indian standards.

Countries like have already following WHTC, some other may introduce same near future. Yet across world keeps on diverging. situation, harmonization vehicle bit challenging, based dynamics road conditions, patterns, environmental etc. Thus, more concerted research needed evolution common universal implementable so uniformity information policies available public could be maintained.
