UB study finds link between ambient ozone exposure, artery wall thickness

Green Car Congress

Long-term exposure to ambient ozone appears to accelerate arterial conditions that progress into cardiovascular disease and stroke, according to a new University at Buffalo study. Atherosclerosis refers to the build-up of plaque, or fatty deposits, in the artery walls, which, over time, restricts blood flow through the arteries.

Fast action on black carbon, ozone and methane could help limit global temperature rise to 2 degrees C

Green Car Congress

Global benefits from full implementation of the identified measures in 2030 compared to the reference scenario. Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F)—and

Life cycle analysis of three battery chemistries for PHEVs and BEVs; environmental impacts higher than expected

Green Car Congress

On a per-storage basis, the team found that the NiMH technology was found to have the highest environmental impact, followed by NCM and then LFP, for all categories considered except ozone depletion potential. They also found higher life cycle global warming emissions than have been previously reported.

EPA proposes stringent new emissions standards for light-, medium-, heavy-duty vehicles for MY 2027 and beyond

Green Car Congress

In this proposed rule, heavy-duty Class 2b and 3 vehicles are referred to as "medium-duty vehicles" (MDVs) to distinguish them from Class 4 and higher vehicles that remain under the heavy-duty program. The light-duty vehicle category includes passenger cars and light trucks consistent with previous EPA criteria pollutant and GHG rules.
