Study shows two-stroke scooters dominant source of air pollution in many cities; asymmetric polluters

Green Car Congress

A study by European researchers has found that two-stroke (2S) scooters, although constituting a small fraction of the fleet, can dominate urban vehicular pollution through organic aerosol and aromatic emission factors up to thousands of times higher than from other vehicle classes. Emission factors (EFs) from scooters and other vehicles.

Motherson Group collaborating with UBQ to bring carbon-negative thermoplastics into auto parts

Green Car Congress

The companies are joining efforts to implement the carbon-negative UBQ thermoplastic ( earlier post ) into auto parts manufactured by Motherson Group for the automotive industry. Adding as little as 10% UBQ GHG to a part can immediately transform it into a carbon-neutral product. Polymers typically emit 1.9

WUSTL study finds use of air conditioning reduces in-car pollution

Green Car Congress

Traffic is a major source of harmful pollutants; daily peak exposures tend to occur near roadways or while traveling—or being stuck—on them. That gave them rare, real-world look at pollutant exposure. With windows closed, the pollutants took longer to enter the vehicle cabin, but also longer to exit it.
