The importance of considering non-exhaust traffic emissions; the role of EVs

Green Car Congress

the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. However, there is more than 15 years of research showing that the contribution of non-exhaust primary particles to the total traffic generated primary particles is significant in urban areas. Further, a 2013 review by Denier van der Gon et al. Background.

Cummins Agrees to Pay $1.6 Billion in U.S. Emissions Fines

The Truth About Cars

We can visibly see them emitting more pollution than vehicles equipped with gasoline engines, though Europe had previously championed diesels as the cleaner option and even subsidized them due to diesel emitting less carbon dioxide. Viewed from an emissions standpoint, it’s hard to make a case for diesel motors.

SEAT pushes forward with CNG line-up

Green Car Congress

SEAT, a member of the Volkswagen Group, continues to spearhead the introduction of compressed natural gas (CNG) technology, giving customers the widest choice of vehicles that are cleaner, more sustainable and offer even greater efficiency. A CNG vehicle reduces CO 2 emissions by about 25% compared to a gasoline-driven equivalent.
