Study finds significant link between PM2.5 pollution and neurological disorders in US

Green Car Congress

pollution was significantly associated with an increased risk of hospital admissions for several neurological disorders, including Parkinson’s disease, Alzheimer’s disease, and other dementias, in a long-term study of more than 63 million older US adults, led by researchers at Harvard T.H. Chan School of Public Health.

Study finds that replacing older, highly polluting school buses could lead to 1.3 million fewer daily absences annually

Green Car Congress

Replacing all of the oldest, highly polluting school buses in the US could lead to 1.3 Even relatively short commutes on school buses can dominate students’ daily air pollution exposures. Applying their results nationwide, the researchers extrapolated that replacing all pre-2000 model school buses would lead to more than 1.3

China-based study concludes using political incentives to fight pollution is costly and inefficient

Green Car Congress

The study looked at water quality regulations and found that local officials more heavily enforced regulations on polluting firms that were monitored and tracked by the central government, while not enforcing regulations on firms not tracked. A 10% reduction in pollution led to a 3% drop in productivity for China’s polluting industries.

California Air Resources Board posts revised draft of strategy to reduce “Super Pollutants”

Green Car Congress

The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. SLCPs are a category of pollutants which remain in the atmosphere for a relatively brief period, but have global warming potentials that are much higher than those of CO 2.

Latest GHG Inventory shows California remains below 2020 emissions target; much steeper rate of GHG reductions required

Green Car Congress

The data shows a slight increase in overall emissions from the previous year, and a slight decline in emissions from transportation, which is the state’s main source of both GHGs and air pollutants. CARB has approved additional measures to reduce emissions of greenhouse gases from super pollutants that must also be reduced significantly.

BIT team develops optimal control strategy for hydrogen engine; near-zero NOx with high power and BTE

Green Car Congress

However, although hydrogen is carbon-free, eliminating many criteria pollutants, the emission of nitrogen oxides (NO x ) remains at a high level in DI hydrogen engines at high loads. BTE @ 2000 rpm and 2500 rpm can be achieved by the turbocharged direct-injection hydrogen engine with near-zero emission. —Bao et al.
