Study finds rising temperatures increase risk of unhealthy ozone levels absent sharp cuts in precursors

Green Car Congress

Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). The RCPs were chosen to represent a broad range of climate outcomes, based on a literature review. Ozone formation.

Renault makes public its lifecycle study of Fluence ICE vs Fluence EV

Green Car Congress

Renault’s comparison of the carbon footprint of EV and ICE vehicles over production, operation and end of life. Since the BEV version has a shorter range, Renault noted, the way in which the miles are accumulated could differ from that of the ICE vehicles.).

Toyota to pioneer use of biosynthetic rubber in engine and drive system hoses

Green Car Congress

Since plants absorb CO 2 from the atmosphere during their lifespan, such bio-materials achieve an estimated 20% reduction in material lifecycle carbon emissions in comparison to conventional petroleum-based hydrin rubber. Jointly developed by Toyota, Zeon Corporation , and Sumitomo Riko Co., Vacuum sensing hose production process.

Calculated E abs from core-shell Mie theory (lines) are shown for the differently sized BC particles and are in generally good agreement with the observations; the colored bands show the uncertainty range in the calculations. The observed mean ambient particle E abs versus RBC during CalNex is shown for comparison (orange line).
