Air quality has increasingly been an issue of social concern in the backdrop of rising industrial and vehicular pollution. While pollution may result from many sources, the Auto fuel policy seeks to control vehicular pollution arising from the dramatic rise in vehicular traffic in the country. The policy provides a …
Research on nanoparticle emissions from vehicles is still in the academic domain. This is largely because the uncertainty over formation of nanoparticles and their measurement methods. As a spillover, regulatory mechanisms are not yet able to take into account this new science. They still use mass of emitted particles
Improved engine technology and fuel quality has thus created a new debate. “Ironically, particle control regulations may have made the situation worse,” points out Wexler, referring to increased nanoparticle emissions. Andreas Mayer, an engineering consultant based in Switzerland, does not quite agree. “Engine development does reduce the number of the …
The Western world has come a long way in its drive to reduce air pollution from vehicles. Just over a decade back, the focus was on total suspended particulate matter (which includes natural dust too) and the black smoke vehicles emitted. Epidemiological evidence made governments shift the focus to respirable …
The current emission standards and safety measures for conversion of in-use vehicles to CNG are extremely lax. The emission standards only require the vehicles to meet the equivalent standards for diesel and petrol vehicles in force in the year of manufacture. This means that a pre-1996 vehicle after being converted …
Pressure from the automobile industry is delaying implementation of tighter vehicular emission norms in cities across India. Though four-wheelers in 11 cities, including the four metros, switched from Bharat Stage (BS) III emission norms to BS IV on April 1, other cities supposed to make the switch from BS II …
